TEM01*:

You see before you an OmTech Polar 350, a 50W CO2 laser for engraving and cutting various materials.

[[File:Omtech-laser-cutter.jpg|thumb|Photo of Omtech laser cutter at the space]]

In the desk drawer below the laser, you find a rotary attachment for engraving round objects.

Currently, Thomas (TEM01* on discord) has taken responsibility for this machine. If you have questions, contact him or someone else certified to use the laser.

== Laser Documentation, Use, and Rules ==
This document is not considered a replacement for an in-person training on the laser. In person training is required before use.

=== What Can I Cut or Engrave on the Laser ===
The laser is pretty good at cutting and engraving many materials made of hydrocarbons, and a few that aren't. When choosing materials for the laser cutter, materials that cut well without burning or melting are desired. Many hard plastics work well. Materials that are thicker than '''¼''' will not cut on the laser because the focal length of the lens is too short. There are a few materials that are not safe to cut, and are banned. This is typically for one of 3 reasons:
* They release too much sticky smoke, which builds up in the enclosure/ductwork and is a fire hazard.
* They release poisonous gas, for example, cyanide. Avoid plastics with a carbon-nitrogen bond (e.g. ABS). Research new plastics and get in touch with someone before use.
* They release corrosive gas (which is also poisonous). Do not cut PVC (vinyl) based materials, or any other materials with chlorine or fluorine atoms.

Additionally, avoid avoid overly reflective materials, or things that take a lot of energy to melt, such as metals. Remember, the laser has to either burn away the material or vaporize it. Materials that will not burn or sublimate will product a liquid layer that vaporizes. This causes interesting effects when engraving materials such as stones; sometimes leaving a layer of rock that was temporarily molten. Materials that do not burn or sublimate should not be cut on our lasers. Cutting metals often requires a laser 10 times more powerful (~500W) than this CO2 laser for a reason. When in doubt about a material, ask someone! There may be a solution to finish your project with a material that wouldn't normally be recommended if we think outside the box.

=== Orientation and Safety ===
To use the laser, first turn on the ventilation system. Currently, there is two separate fans, the large one inside the electrical closet, and a smaller fan above the laser. Plug in the fan inside the closet, then turn on the small fan by pressing "FAST" on it's controller.

The top lid and debris catch tray are interlocked. This means the machine will not operate unless both are fully closed.

The laser is controlled by the computer above it, and turned on using the key switch on the front right of the laser. When the laser is turned on, the large illuminated pushbutton can start a cutting job, so do not press it until you are ready.

Make sure to only cut approved materials on the laser, this will mitigate fire hazards and noxious fumes. The laser MUST be supervised continuously during operation. If the material being cut catches fire, or too much smoke is being generated, turn off the laser. If the material being cut continues to burn, take the fire blanket out of the pouch on the wall, open the laser, and smother the fire.

===== Safety Checklist: =====

* Use only approved materials
* Make sure ventilation is running properly
* Keep lid and debris catch tray closed (both are interlocked)
* Be aware of the location of the first aid kit, the fire blanket, and fire extinguisher
* Do not leave the machine unattended
* Stop the machine if excessive smoke is generated or is building up in the machine
* Don't stare at the bright cut spot
* Don't open the machine while it is running. Wait a while after it's done for smoke to clear.

=== Software ===
The laser is controlled using the Lightburn software on the computer. This takes in SVG files, or can be used to draw a design from scratch. Primary colors are used to control the different power levels for cutting and engraving.

Lightburn has a number of tutorials available here: https://lightburnsoftware.com/pages/tutorials Training for how to use the laser will focus on operating the machine, not creating a design file. If you already have a preferred graphics editor, great! We should be able to import files from it. Please convert all text to a vector path before exporting it to avoid font library issues.Some other design rules for creating a design are related to colors:[[File:LightburnOverview.png|thumb|1076x1076px|Lightburn Overview|center]]

In the above example, there are 3 rectangles to be cut. Their color defines the power and speed settings that will be used. Additionally, the color controls the order in which the cuts/engravings will be made. Generally, it is best practice to engrave any images first (black grayscale in this case), then cut out any interior holes (blue in this case), then use the final setting to cut the work out of the larger piece of material (red in this case). This reduces the chance of the material shifting and throwing things out of alignment.

The per color settings on the top right control the speed, power, cut mode (Line/Fill) whether or not to cut that color (output), whether or not to show it in the editor (show), and whether or not to turn on the air assist (Air). Air assist should be turned on at all times. There are a few exceptions, but turning off the air has a chance to let smoke accumulate on the lens and burn it.

You have a large variety of possible colors available to you when designing a file, and the software lets you reorder them if you make a mistake to cut and engrave in the incorrect order. One of the main design constraints is when engraving images, you will want to use a grayscale black and white image. If you need more than one image engraved on a piece, at different settings, we can try to create a grayscale image with a different color (blue to white), but this will depend on your design software. If all else fails, just run two print jobs on the same material.

On the right there is another tab labeled move. This lets you manually move the laser head over your material to make sure it is in the right area, and also focus to the material. To focus, with a 2in lens a Z height of 17 mm should focus to the level of the honeycomb. Move the Z up by the thickness of the work to focus. Moving up is a smaller Z number. No this doesn't make sense, thanks for asking.

Before sending the job to the laser, Alt+P will preview the cutting job so you can check it for any errors.

=== Material Settings ===
To help with dialing in new materials, Lightburn has a Material Test Generator utility found under tools. If you haven't used this before, ask for assistance.
[[File:MaterialTestGenerator.png|thumb|870x870px|Material Test Generator|center]]

This lets you make test coupons for new materials, that you can leave in the space for others to reference in the future.

Using these test coupons, you can choose the right speed and power settings for your project.

=== Maintenance ===
This laser cutter is still pretty new to EMS, so the frequency and exact maintenance steps required for this laser are still being determined. For the time being (1-2-26) here are the things TEM01* has run into in previous workplaces.

<nowiki>**</nowiki>These instructions have not been updated to be applicable to the OmTech Laser, and should be updated when the maintenance occurs.**

===== Clean focus lens: =====
Remove assembly

Clean front (faces down when in laser) of focus lens by dripping small amount of lens solution on the lens and gently wiping with clean q-tip or lens paper.

===== Z-Calibration: =====

===== Air Assist: =====

===== Honeycomb (Cutting table): =====
If there is a large buildup of small pieces of material in the honeycomb, take it out and empty it. When replacing, be sure to properly align, by pushing it against the guides in the top left corner.

===== Focus lens mirror: =====
Take out the lens assembly and clean the mirror as if you were cleaning the lens, but wipe along the length of the mirror instead of in circles.

===== Clean beam optics: =====
The mirror is cleaned with horizontal strokes, and the beam window with circular ones. These should only be cleaned gently bi-monthly unless visible build-up of soot has occurred.

===== Beam x-y calibration: =====
The x-y beam path does not go out of calibration often, and is very robust, but can occasionally cause problems that are very difficult to troubleshoot. The x-y mirror is adjusted to ensure that the beam is parallel to the x-axis armature.

Maintenance guidelines from the [https://cdn.shopify.com/s/files/1/0280/0012/4993/files/USB-0503-U4_compressed.pdf?v=1737100697 manual] :

"Follow the instructions below when maintaining:

* Clean and cool water or laser-safe coolant must be provided to the system at all times.
* Confirm the tank is at least two-thirds full before and after each use.
* The work bed must be cleaned and the waste bin emptied every day.
* The lenses of the 1st and 2nd mirror housing, the 3rd mirror, the focus lens, and the camera must be checked every day and cleaned if required.
* The exhaust system must be checked every week and cleaned if required.
* The guide rails should be cleaned and lubricated at least twice a month.
* The air assist must be checked every month and cleaned if required.
* All other components of the laser machine should be checked every month and cleaned where required.
* Replace your coolant every three months for best results. Even if it is visibly clean month after month, drain it, clean the entire system, and replace it at least once a year.

In commercial settings, keep a cleaning and maintenance log in a visible location near the engraver. Have operators date and sign the log as cleaning and maintenance are carried out."

Additionally, avoid avoid overly reflective materials, or things that take a lot of energy to melt, such as metals. Remember, the laser has to either burn away the material or vaporize it. Materials that will not burn or sublimate will product a liquid layer that vaporizes. This causes interesting effects when engraving materials such as stones; sometimes leaving a layer of rock that was temporarily molten. Materials that do not burn or sublimate should not be cut on our lasers. Cutting metals often requires a laser 10 times more powerful (~500W) than this CO2 laser for a reason. When in doubt about a material, ask someone! There may be a solution to finish your project with a material that wouldn't normally be recommended if we think outside the box.

=== Orientation and Safety ===
To use the laser, first turn on the ventilation system. Currently, there is two separate fans, the large one inside the electrical closet, and a smaller fan above the laser. Plug in the fan inside the closet, then turn on the small fan by pressing "FAST" on it's controller.

The top lid and debris catch tray are interlocked. This means the machine will not operate unless both are fully closed.

The laser is controlled by the computer above it, and turned on using the key switch on the front right. When the laser is turned on, the large illuminated pushbutton can start a cutting job, so do not press it until you are ready.

Make sure to only cut approved materials on the laser, this will mitigate fire hazards and noxious fumes. The laser MUST be supervised continuously during operation. If the material being cut catches fire, or too much smoke is being generated, turn off the laser. If the material being cut continues to burn, take the fire blanket out of the pouch on the wall, open the laser, and smother the fire.

===== Safety Checklist: =====

* Use only approved materials
* Make sure ventilation is running properly
* Keep lid and debris catch tray closed (both are interlocked)
* Be aware of the location of the first aid kit, the fire blanket, and fire extinguisher
* Do not leave the machine unattended
* Stop the machine if excessive smoke is generated or is building up in the machine
* Don't stare at the bright cut spot
* Don't open the machine while it is running. Wait a while after it's done for smoke to clear.

=== <s>Operation</s> Software ===
The laser is controlled using the Lightburn software on the computer. This takes in SVG files, or can be used to draw a design from scratch. Primary colors are used to control the different power levels for cutting and engraving.

Lightburn has a number of tutorials available here: https://lightburnsoftware.com/pages/tutorials Training for how to use the laser will focus on operating the machine, not creating a design file. If you already have a preferred graphics editor, great! We should be able to import files from it. Please convert all text to a vector path before exporting it to avoid font library issues.

Some other design rules for creating a design are related to colors:
[[File:LightburnOverview.png|thumb|1076x1076px|Lightburn Overview|center]]

In the above example, there are 3 rectangles to be cut. Their color defines the power and speed settings that will be used. Additionally, the color controls the order in which the cuts/engravings will be made. Generally, it is best practice to engrave any images first (black grayscale in this case), then cut out any interior holes (blue in this case), then use the final setting to cut the work out of the larger piece of material (red in this case). This reduces the chance of the material shifting and throwing things out of alignment.

You have a large variety of possible colors available to you when designing a file, and the software lets you reorder them if you make a mistake to cut and engrave in the incorrect order. One of the main design constraints is when engraving images, you will want to use a grayscale black and white image. If you need more than one image engraved on a piece, at different settings, we can try to create a grayscale image with a different color (blue to white), but this will depend on your design software. If all else fails, just run two print jobs on the same material.

On the right there is another tab labeled move. This lets you manually move the laser head over your material to make sure it is in the right area, and also autofocus to the material.

=== Material Settings ===
To help with dialing in new materials, Lightburn has a Material Test Generator utility found under tools. If you haven't used this before, ask for assistance.
[[File:MaterialTestGenerator.png|thumb|870x870px|Material Test Generator|center]]

This lets you make test coupons for new materials, that you can leave in the space for others to reference in the future.

Using these test coupons, you can choose the right speed and power settings for your project.

[[File:LaserTestCoupons.jpg|thumb|center|607x607px]]
=== Maintenance ===
This laser cutter is still pretty new to EMS, so the frequency and exact maintenance steps required for this laser are still being determined. For the time being (1-2-26) here are the things TEM01* has run into in previous workplaces.

<nowiki>**</nowiki>These instructions have not been updated to be applicable to the OmTech Laser, and should be updated when the maintenance occurs.**

===== Clean focus lens: =====
Remove assembly

Clean front (faces down when in laser) of focus lens by dripping small amount of lens solution on the lens and gently wiping with clean q-tip or lens paper.

===== Z-Calibration: =====

===== Air Assist: =====

===== Honeycomb (Cutting table): =====
If there is a large buildup of small pieces of material in the honeycomb, take it out and empty it. When replacing, be sure to properly align, by pushing it against the guides in the top left corner.

===== Focus lens mirror: =====
Take out the lens assembly and clean the mirror as if you were cleaning the lens, but wipe along the length of the mirror instead of in circles.

===== Clean beam optics: =====
The mirror is cleaned with horizontal strokes, and the beam window with circular ones. These should only be cleaned gently bi-monthly unless visible build-up of soot has occurred.

===== Beam x-y calibration: =====
The x-y beam path does not go out of calibration often, and is very robust, but can occasionally cause problems that are very difficult to troubleshoot. The x-y mirror is adjusted to ensure that the beam is parallel to the x-axis armature.

Maintenance guidelines from the [https://cdn.shopify.com/s/files/1/0280/0012/4993/files/USB-0503-U4_compressed.pdf?v=1737100697 manual] :

"Follow the instructions below when maintaining:

* Clean and cool water or laser-safe coolant must be provided to the system at all times.
* Confirm the tank is at least two-thirds full before and after each use.
* The work bed must be cleaned and the waste bin emptied every day.
* The lenses of the 1st and 2nd mirror housing, the 3rd mirror, the focus lens, and the camera must be checked every day and cleaned if required.
* The exhaust system must be checked every week and cleaned if required.
* The guide rails should be cleaned and lubricated at least twice a month.
* The air assist must be checked every month and cleaned if required.
* All other components of the laser machine should be checked every month and cleaned where required.
* Replace your coolant every three months for best results. Even if it is visibly clean month after month, drain it, clean the entire system, and replace it at least once a year.

In commercial settings, keep a cleaning and maintenance log in a visible location near the engraver. Have operators date and sign the log as cleaning and maintenance are carried out."

EMS Safety Policies

2026-02-13T05:10:08Z

TEM01*:

{{MemberHandbook-nav}}

Eugene Makerspace is not responsible for your personal safety, as agreed upon in the [[Media:EugMakerSpace.EMS WAIVER.odt|liability waiver]], but there are a number of policies and resources intended to help keep everyone safe.

As of 2-12-26, TEM01* (Thomas) is acting as safety officer.

==== Facility Map: ====
Please familiarize yourself with the facility and the location of the first aid kit, breaker panel, and fire extinguishers. It's not a big place, shouldn't be a problem.

==== Evacuation Plan: ====

==== Flammable/Hazardous Materials: ====
Flammable or hazardous materials must be returned to their storage location before you leave the building. This location is likely the flammables cabinet. If you bring new materials onsite, they must be well labeled with their hazards and assigned a proper storage location. If you need help with this, talk to a board member.

==== Lasers (and really bright lights): ====
Lasers are great! Losing your vision, less so. Do not aim lasers at others. Since it would not be possible to have a controlled area in our current location, all lasers have to be Class 3R or below. This means all lasers have to be below 5mW of optical output power, or sufficiently enclosed and controlled to be considered a Class 1 laser (no accessible laser light). Lasers above 5mW need to be approved by the board, and the enclosure method verified. Exceptions to the Class 3R limit can be made, with laser hazard analysis. (Laser projectors would be an example of a possible exception with proper controls).

While really bright LEDs are super cool, don't shine them in peoples eyes without consent. The temporary flash blindness can be a safety hazard.

Contact @TEM01* (Thomas) with any laser safety questions.

==== Dust, Fumes, Sparks, and other irritants: ====
Wear proper PPE for the task at hand (safety glasses, dust masks), and familiarize yourself with the dust/fume extraction available for the tool you are using. Contact the tool owner if you have questions, or if there are hazards not being properly mitigated.

EMS Code Of Conduct

2026-02-13T05:03:41Z

TEM01*: Added a non exhaustive list of unacceptable behaviors

{{MemberHandbook-nav}}

The Eugene MakerSpace has a few community norms, revolving around communication and cooperation. Please mindful of others and these guidelines.

* '''We are inclusive''': an lgbtq friendly space, women friendly space, minority friendly space.
* '''We are non-professional''': EMS is not a coworking space and not a business networking space, we show up to work on our side projects and crazy ideas.
* '''We are project-focused''': Socialization is encouraged, but should not impede others ability to use the space for their own project.
* '''We are family-friendly on-site''': minors must be supervised by the member who brings them.
* '''We vote with our presence''': in order for the most present and engaged individuals to shape what the makerspace becomes, decision making happens at “Mod Your Makerspace” work sessions.
* '''We communicate respectfully''': so that everyone is on the same page about how different sorts of communication can foster or dampen engagement we follow Recurse Center’s Social Rules and try not to:
** try to not “well actually”
** try to not feign surprise
** try to not backseat drive
** try to not engage in subtle -isms
* '''We are curious''': the makerspace is a place to explore ideas, ask questions, and value learning as much as outcome.
* '''We encourage one-another''': the makerspace is a safe place to get excited about possibilities, and share the skills needed to bring our dreams to fruition.
* '''We are involved in the Eugene community''': the makerspace exists in a web of mission-aligned communities and organizations throughout the city.

Additionally, there are a few more robust rules, just in case:

====== Unacceptable behavior ======

* No violence or threats of violence
* No discriminatory language
* No posting or displaying sexually explicit material
* Non-consensual physical contact or sexual attention
* Intimidation of any kind
* Unsafe behavior
* Political lobbying

Ems Member Storage

2026-02-09T03:39:59Z

TEM01*:

{{DISPLAYTITLE:EMS Member Storage}}

== How It Works ==

* All surfaces should be kept clear when not actively in use. Leaving tools, projects or materials in a shared space is not ok; we don't have room for it and it discourages other members from making use of the space.

* To avoid the need for members to carry everything single thing back and forth from the space, some storage is offered to each member in good standing. Members may request more space for projects, materials and tools.

* Storage is charged in monthly increments. For a longer-term reservation, it may be cheaper and simpler to upgrade to a higher tier membership which comes with more storage options. We can't subdivide a monthly charge.

* All storage reservations should be made through the room lead or board of directors.
** Storage requests may be denied if no sufficient or appropriate space is available, or if the space is already reserved for use during the proposed period. Any fees already paid will be reimbursed. If the cost is rolled into the membership tier, a discount of equivalent value may be offered.

* Talk to the room lead if you have something to donate. We have a process for handling donations and long-term loans. Anything else falls under our storage policy. We have to be even-handed about this; even if its a really useful tool or valuable materials, we have limited space and cannot operate as our member's extended storage unit.

== Do's & Don'ts ==

* Some membership tiers include access to storage: <b>do</b> claim it if you intend to use it. Otherwise, inform the BoD if you know you will not be using it, so we can make it available to someone else.
* Requests for storage may not always be granted. <b>Do</b> plan ahead and reserve appropriate storage space for your projects to avoid any inconvenience.
* Please <b>do</b> coordinate with the room lead if a project requires being <em>temporarily</em> left on-site, e.g. to let glue dry.
** You must clearly label who it belongs to and the date it was left
** Notify other members on Discord of the situation and when you'll be back to move it
** Ensure you are available to remove or store your things the following day.
* Please <b>don't</b> leave a project out in a work area with a plan to resume the next day.
* <b>Don't</b> leave your things in apparently empty/unused space
* <b>Avoid</b> getting your tools and materials mixed up with EMS property. If you bring a tool or other thing on-site, either store it in your own reserved storage space or take it away with you.

== Rationale and Fee Structure ==

The majority of our income goes back out as rent to our landlord at a rate based on square footage, meaning our ability to offer equipment and activities to members is largely constrained by having the space to house it. This fact guides our policy and fee structure for member storage; fees are proportional to the actual space removed from use for or by anyone else. Floor area is therefore at a premium while stacked storage is discounted.

Storage fees may be revised based on space availability and as our rent and operating costs change over time.

== Storage Options ==

=== Floor Area: $4/ft<sup>2</sup>/month ===

Sometimes you need to stack up a bunch of lumber or keep a specific tool at the space for the duration of a project. When space permits, we can tape off an area for a member, charged at a $4 / square-foot / month.

=== Wire Storage Racks: $3/ft<sup>2</sup>/month ===

If you can, you'll save us space and you money by using space on one of the wire storage racks or shelves. $3 / square-foot / month.

=== 27 Gallon Tote: $10/month ===

The rack of large plastic totes is intended for members to reserve. Your membership tier may qualify you for one of these prepaid

=== Steel Locker: $10/month ===

The bank of lockers is intended for members to reserve. Supply your own padlock if needed. Your membership tier may qualify you for one of these prepaid.

== End of Storage Subscription ==
When membership ends or a reservation expires, the member is expected to empty their storage space promptly. Three (3) attempts will be made to contact the member to collect any belongings left in member storage. The first contact attempt will be performed within one (1) week after access is revoked, using the primary contact information provided with membership. If one (1) week passes without response, then a second notice will be sent to all provided contact information. The final notice will occur through the same channels after one week without response.

After the final notice, the member will have one (1) additional week to respond, at which point any uncollected property will be considered abandoned property and revert to EMS ownership to be put to use or disposed of as the Board of Directors deems appropriate. Any additional grace period for property collection after this point is decided by the Board of Directors on a case by case basis, but is not to exceed two (2) months. As discussed above, space is limited at the EMS location and it may not be possible for EMS to hold property for extended periods of time.

Because of the limited space, missing a scheduled pick-up date without notice will be grounds for immediate rescindment of the grace period. Notice and/or explanation must be provided within 48 hours, before or after, of the pick-up date. The rescheduled pick-up date must also fall within the allowed grace period. Any belongings not claimed within the given time limit (as discussed above) will not be eligible for reclamation.

TEM01*: Improved the operation section

You see before you an OmTech Polar 350, a 50W CO2 laser for engraving and cutting various materials.

[[File:Omtech-laser-cutter.jpg|thumb|Photo of Omtech laser cutter at the space]]

In the desk drawer below the laser, you find a rotary attachment for engraving round objects.

Currently, Thomas (TEM01* on discord) has taken responsibility for this machine. If you have questions, contact him or someone else certified to use the laser.

== Laser Documentation, Use, and Rules ==
This document is not considered a replacement for an in-person training on the laser. In person training is required before use.

=== What Can I Cut or Engrave on the Laser ===
The laser is pretty good at cutting and engraving many materials made of hydrocarbons, and a few that aren't. When choosing materials for the laser cutter, materials that cut well without burning or melting are desired. Many hard plastics work well. Materials that are thicker than '''¼''' will not cut on the laser, the focal length of the lens we use is too short. There are a few materials that are not safe to cut, and are banned. This is typically for one of 3 reasons:
* They release too much sticky smoke, which builds up in the enclosure/ductwork and is a fire hazard.
* They release poisonous gas, for example, cyanide. Avoid plastics with a carbon-nitrogen bond. Research new plastics and get in touch with someone before use.
* They release corrosive gas (which is also poisonous). Do not cut PVC (vinyl) based materials, or any other materials with chlorine or fluorine atoms.

Additionally, avoid avoid overly reflective materials, or things that take a lot of energy to melt, such as metals. Remember, the laser has to either burn away the material or vaporize it, so in materials that will not burn or sublimate, there will be a liquid layer that then vaporizes. This causes interesting effects when engraving materials such as stones; sometimes leaving a layer of rock that was temporarily molten. Materials that do not burn or sublimate should not be cut on our lasers. CO2 Laser cutters used for cutting metals are upwards of 500W for a reason. When in doubt about a material, ask someone! There may be a solution to finish your project with a material that wouldn't normally be recommended if we think outside the box.

=== Orientation and Safety ===
To use the laser, first turn on the ventilation system. Currently, this is two separate fans, the large one inside the electrical closet, and the smaller fan above the laser. Plug in the fan inside the closet, then turn on the small fan by pressing "FAST" on it's controller.

The laser is controlled by the computer above it, and turned on using the key switch on the front right. When the laser is turned on, the large illuminated pushbutton can start a cutting job, so do not press it until you are ready.

Make sure to only cut approved materials on the laser, this will mitigate fire hazards and noxious fumes. The laser MUST be supervised continuously during operation. If the material being cut catches fire, or too much smoke is being generated, turn off the laser. If the material being cut continues to burn, take the fireblanket out of the pouch on the wall, open the laser, and smother the fire.

===== Safety Checklist: =====

* Use approved materials
* Make sure ventilation is running properly
* Be aware of the location of the first aid kit, the fire blanket, and fire extinguisher
* Do not leave the machine unattended
* Stop the machine if excessive smoke is generated or is building up in the machine
* Don't stare at the bright cut spot
* Dont open the machine while it is running. Wait a while after it's done for smoke to clear.

=== Operation ===
The laser is controlled using the lightburn software on the computer. This takes in SVG files, or can be used to draw a design from scratch. Primary colors are used to control the different power levels for cutting and engraving.

Lightburn has a number of tutorials available https://lightburnsoftware.com/pages/tutorials Training for how to use the laser will focus on printing a job, not creating a design file. If you already have a prefered graphics editor, great! We should be able to import files from it. Please convert all text to a vector path before exporting it to avoid font library issues.

Some other design rules for creating a design are related to colors:
[[File:LightburnOverview.png|thumb|1076x1076px|Lightburn Overview|center]]

In this image, there are 3 rectangles to be cut. Their color defines the power and speed settings that will be used. Additionally, the color controls the order in which the cuts/engravings will be made. Generally, it is best practice to engrave any images first (black grayscale), then cut out any interior holes (blue in this case), then use the final setting to cut the work out of the larger piece of material. This reduces the chance of the material shifting and throwing things out of alignment.

You have a large variety of possible colors available to you when designing a file., and the software lets you reorder them if you make a mistake to cut and engrave in the correct order. One of the main design constraints is when engraving images, you will want to use a grayscale black and white image. If you need more than one image engraved on a piece, at different settings, we can try to create a grayscale image with a different color (blue to white), but this will depend on your design software. If al else fails, just run two print jobs on the same material.

On the right there is another tab labeled move. This lets you manually move the laser head over your material to make sure it is in the right area, and also autofocus to the material.

=== Material Settings ===
To help with dialing in new materials, Lightburn has a Material Test Generator utility found under tools. If you haven't used this before, ask for assistance.
[[File:MaterialTestGenerator.png|thumb|870x870px|Material Test Generator|center]]

This lets you make test coupons for new materials, that you can leave in the space for others to reference in the future.

Using these test coupons, you can choose the right speed and power settings for your project.

=== Maintenance ===
This laser cutter is still pretty new to EMS, so the frequency and exact maintenance steps required for this laser are still being determined. For the time being (1-2-26) here are the things TEM01* has run into in previous workplaces.
These instructions have not been updated to be applicable to the OmTech Laser, and should be updated when the maintenance occurs.

===== Clean focus lens: =====
Remove assembly

Clean front (faces down when in laser) of focus lens by dripping small amount of lens solution on the lens and gently wiping with clean q-tip or lens paper.

===== Z-Calibration: =====

===== Air Assist: =====

===== Honeycomb (Cutting table): =====
If there is a large buildup of small pieces of material in the honeycomb, take it out and empty it. When replacing, be sure to properly align, by pushing it against the guides in the top left corner.

===== Focus lens mirror: =====
Take out the lens assembly and clean the mirror as if you were cleaning the lens, but wipe along the length of the mirror instead of in circles.

===== Clean beam optics: =====
The mirror is cleaned with horizontal strokes, and the beam window with circular ones. These should only be cleaned gently bi-monthly unless visible build-up of soot has occurred.

===== Beam x-y calibration: =====
The x-y beam path does not go out of calibration often, and is very robust, but can occasionally cause problems that are very difficult to troubleshoot. The x-y mirror is adjusted to ensure that the beam is parallel to the x-axis armature.

TEM01*: /* Orientation and Safety */

You see before you an OmTech Polar 350, a 50W CO2 laser for engraving and cutting various materials.

[[File:Omtech-laser-cutter.jpg|thumb|Photo of Omtech laser cutter at the space]]

In the desk drawer below the laser, you find a rotary attachment for engraving round objects.

Currently, Thomas (TEM01* on discord) has taken responsibility for this machine. If you have questions, contact him or someone else certified to use the laser.

== Laser Documentation, Use, and Rules ==
This document is not considered a replacement for an in-person training on the laser. In person training is required before use.

=== What Can I Cut or Engrave on the Laser ===
The laser is pretty good at cutting and engraving many materials made of hydrocarbons, and a few that aren't. When choosing materials for the laser cutter, materials that cut well without burning or melting are desired. Many hard plastics work well. Materials that are thicker than '''¼''' will not cut on the laser, the focal length of the lens we use is too short. There are a few materials that are not safe to cut, and are banned. This is typically for one of 3 reasons:
* They release too much sticky smoke, which builds up in the enclosure/ductwork and is a fire hazard.
* They release poisonous gas, for example, cyanide. Avoid plastics with a carbon-nitrogen bond. Research new plastics and get in touch with someone before use.
* They release corrosive gas (which is also poisonous). Do not cut PVC (vinyl) based materials, or any other materials with chlorine or fluorine atoms.

If the material being cut continues to burn, take the fireblanket out of the pouch on the wall, open the laser, and smother the fire.

===== Safety Checklist: =====

* Use approved materials
* Make sure ventilation is running properly
* Be aware of the location of the first aid kit, the fire blanket, aand fire extinguisher
* Do not leave the machine unattended
* Stop the machine if excessive smoke is generated or is building up in the machine
* Don't stare at the bright cut spot
* Dont open the machine while it is running. Wait a while after it's done for smoke to clear.

=== Operation ===
The laser is controlled using the lightburn software on the computer. This takes in SVG files, or can be used to draw a design from scratch. Primary colors are used to control the different power levels for cutting and engraving.
[[File:LightburnOverview.png|thumb|1076x1076px|Lightburn Overview]]

In this image, there are 3 rectangles to be cut. Their color defines the power and speed settings that will be used. Additionally, the color controls the order in which the cuts/engravings will be made. Generally, it is best practice to engrave any images first (black grayscale), then cut out any interior holes (blue in this case), then use the final setting to cut the work out of the larger piece of material. This reduces the chance of the material shifting and throwing things out of alignment.

On the right there is another tab labeled move. This lets you manually move the laser head over your material to make sure it is in the right area, and also autofocus to the material.

=== Material Settings ===
To help with dialing in new materials, Lightburn has a Material Test Generator utility found under tools. If you haven't used this before, ask for assistance.
[[File:MaterialTestGenerator.png|thumb|870x870px|Material Test Generator]]

This lets you make test coupons for new materials, that you can leave in the space for others to reference in the future.

Using these test coupons, you can choose the right speed and power settings for your project.

=== Maintenance ===
This laser cutter is still pretty new to EMS, so the frequency and exact maintenance steps required for this laser are still being determined. For the time being (1-2-26) here are the things TEM01* has run into in previous workplaces.
These instructions have not been updated to be applicable to the OmTech Laser, and should be updated when the maintenance occurs.

===== Z-Calibration: =====

===== Air Assist: =====

===== Honeycomb (Cutting table): =====
If there is a large buildup of small pieces of material in the honeycomb, take it out and empty it. When replacing, be sure to properly align, by pushing it against the guides in the top left corner.

===== Focus lens mirror: =====
Take out the lens assembly and clean the mirror as if you were cleaning the lens, but wipe along the length of the mirror instead of in circles.

===== Clean beam optics: =====
The mirror is cleaned with horizontal strokes, and the beam window with circular ones. These should only be cleaned gently bi-monthly unless visible build-up of soot has occurred.

===== Beam x-y calibration: =====
The x-y beam path does not go out of calibration often, and is very robust, but can occasionally cause problems that are very difficult to troubleshoot. The x-y mirror is adjusted to ensure that the beam is parallel to the x-axis armature.

TEM01*: /* Orientation and Safety */

You see before you an OmTech Polar 350, a 50W CO2 laser for engraving and cutting various materials.

[[File:Omtech-laser-cutter.jpg|thumb|Photo of Omtech laser cutter at the space]]

In the desk drawer below the laser, you find a rotary attachment for engraving round objects.

Currently, Thomas (TEM01* on discord) has taken responsibility for this machine. If you have questions, contact him or someone else certified to use the laser.

== Laser Documentation, Use, and Rules ==
This document is not considered a replacement for an in-person training on the laser. In person training is required before use.

=== What Can I Cut or Engrave on the Laser ===
The laser is pretty good at cutting and engraving many materials made of hydrocarbons, and a few that aren't. When choosing materials for the laser cutter, materials that cut well without burning or melting are desired. Many hard plastics work well. Materials that are thicker than '''¼''' will not cut on the laser, the focal length of the lens we use is too short. There are a few materials that are not safe to cut, and are banned. This is typically for one of 3 reasons:
* They release too much sticky smoke, which builds up in the enclosure/ductwork and is a fire hazard.
* They release poisonous gas, for example, cyanide. Avoid plastics with a carbon-nitrogen bond. Research new plastics and get in touch with someone before use.
* They release corrosive gas (which is also poisonous). Do not cut PVC (vinyl) based materials, or any other materials with chlorine or fluorine atoms.

Additionally, avoid avoid overly reflective materials, or things that take a lot of energy to melt, such as metals. Remember, the laser has to either burn away the material or vaporize it, so in materials that will not burn or sublimate, there will be a liquid layer that then vaporizes. This causes interesting effects when engraving materials such as stones; sometimes leaving a layer of rock that was temporarily molten. Materials that do not burn or sublimate should not be cut on our lasers. Laser cutters used for cutting metals are upwards of 500W for a reason. When in doubt about a material, ask someone! There may be a solution to finish your project with a material that wouldn't normally be recommended if we think outside the box.

=== Orientation and Safety ===
To use the laser, first turn on the ventilation system. Currently, this is two separate fans, the large one inside the electrical closet, and the smaller fan above the laser. Plug in the fan inside the closer, then turn on the small fan by pressing "FAST" on it's controller.

The laser is controlled by the computer above it, and turned on using the key switch on the front left. When the laser is turned on, the large illuminated pushbutton can start a cutting job, so do not press it until you are ready.

Make sure to only cut approved materials on the laser, this will mitigate fire hazards and noxious fumes. The laser MUST be supervised continuously during operation. If the material being cut catches fire, or too much smoke is being generated, turn off the laser with the keyswitch. If the material being cut continues to burn, take the fireblanket out of the pouch on the wall, open the laser, and smother the fire.

<h1>3D Printer Use, Policies, And Etiquette</h1>
3D printers are typically easy to use, reliable machines. These policies aim to keep them that way.

== You MUST be a EMS member, and be qualified by another EMS member, to use the 3d printers. ==

== You must ACTIVELY supervise the first layer of your print, as a bare minimum. ==
<h2>Octoprint</h2>
