Project Objectives

The following is the list of design goals and hoped-for features. Core Objectives Build a CNC machine capable of milling acrylic or pressboard - the standard backing board of the ubiquitous inexpensive clipboard. Build the machine using mostly salvaged and found parts. Machine should operate using a standard Arduino Uno board, with the standard CNC expansion board kit. Workflow should be possible from Error creating thumbnail: Unable to save thumbnail to destination Inventables Easel to Error creating thumbnail: Unable to save thumbnail to destination Universal Gcode Sender. Purchased parts should ideally be the cheapest available. Machine should have interchangeable tool functionality, so the gantry can be used to utilize a number of different tools. Those tools potentially could include: Error creating thumbnail: Unable to save thumbnail to destination Dremel Carver (or inexpensive WEN alternative) - possibly mounting the tool-end of the Flexible-Shaft attachment, to reduce machine vibration. Error creating thumbnail: Unable to save thumbnail to destination Embroidery Hoop on extension arm, allowing a minimally modified sewing machine to create embroidered patches. May be better as a secondary machine. Error creating thumbnail: Unable to save thumbnail to destination Free-Rotating 'Drag Knife' or inexpensive Error creating thumbnail: Unable to save thumbnail to destination Vinyl Cutter replacement blade cartridges. Error creating thumbnail: Unable to save thumbnail to destination Filament Extruder and Hot-End for 3D printing, or Error creating thumbnail: Unable to save thumbnail to destination modified 3D Pen May require secondary Arduino pre-configured as 3D printer instead of CNC. Possibly could use a serial port switchbox to switch arduinos, usb, etc?? Error creating thumbnail: Unable to save thumbnail to destination Inexpensive soldering iron with copper wire to replace tip, for cutting foam. Error creating thumbnail: Unable to save thumbnail to destination Reciprocating needle cutter for cutting cardboard or foam-core. Error creating thumbnail: Unable to save thumbnail to destination Pen or Pencil holder for use as plotter. Error creating thumbnail: Unable to save thumbnail to destination Uses Part 1 Error creating thumbnail: Unable to save thumbnail to destination Uses Part 2 Error creating thumbnail: Unable to save thumbnail to destination Uses Part 3 Fabric markers for making t-shirts/wall hangings, paint markers or metallic sharpies for marking surfaces like glass, mirrors, tile, and chalkboards. Error creating thumbnail: Unable to save thumbnail to destination Glue pen for heat embossing Error creating thumbnail: Unable to save thumbnail to destination Ball-point pen without ink, for use as pressure embosser/creasing tool. Error creating thumbnail: Unable to save thumbnail to destination Cutting Laser - at a later date, as funding permits Secondary Objectives Clamping area should be able to accommodate a standard 9" x 12.5" clipboard, with the clip removed, whether or not it can mill that entire area. Tertiary Objectives The footprint of the completed machine should not exceed 12.5" x 16.5" (to fit inside folding cart for easy transport) Creeping Featuritis - Acquired Objectives It's nearly inevitable when any suitably complicated project drags on, or even goes on hiatus. Eventually you're going to start daydreaming new ideas and features for the build. The Doozer was no exception to this. The trick is to try to make sure that the feature creep is actually a reasonable addition that can be missed out if need be, due to budget or skill constraints. The following is a lits of ideas that cropped up along the way, that made the cut. Redesign machine to use aluminum extrusion for the major structural elements Upgrade to using actual lead screws and aluminum shaft-to-motor couplers from the start - not 'later date' upgrades All parts created components should be either copies of purchaseable replacements, or be capable of being made WITH the machine. Slotted waste-board that allows carriage bolts to travel in the aluminum extrusion below, for clamping materials down with wingnuts. Waste board slats should also be possible to make/replace WITH the machine! Laser Crosshair built into the X Axis to allow for 'same every time' axis zeroing, and thus repeatable jobs. Error creating thumbnail: Unable to save thumbnail to destination USB 10-key number-pad for use as a Error creating thumbnail: Unable to save thumbnail to destination remote positioning/control pendant for the CNC.

Project Status

09/20/2019 - Latest!

Email received from AliExpress. All components of the targeting laser assembly ( crosshair & dot lasers and USB power adapter ) are now in the hands of couriers in the USA.

Beata donated a 2-port USB power converter to the project after I'd ordered the single-USB version, so I may utilize the dual-port unit instead (one for each laser)

09/18/2019

All off-the-shelf structural components have been purchased, and have arrived. All components are measured and 3D modelled in SketchUp Make 2016. The 3 axis assemblies have been assembled in SketchUp.

Currently developing a modified 3D model of the tolerances of the aluminum extrusions, that model will help me easily create functional 3D-printed parts that fit properly.

Maximum workspace dimensions seem to be coming in at (305mm x 250mm x 180mm), which is approximately (12in x 11in x 7in). These are the maximum lengths that the linear rails and bearings can accommodate. I suspect these lengths will reduce somewhat as the actual gantry is designed.

Fraggles and Doozers

The Doozers are a race of characters from Jim Henson's Fraggle Rock television series. Doozers love to work all day long. They're tiny, green creatures who usually sport construction helmets, boots, and tool belts. Doozers stand approximately knee-high to Fraggles, at six inches tall.

When compared to the other races within Fraggle Rock, they are by far the most technologically advanced. Most Doozers are construction workers, while others are architects or miners. With the help of various Doozer machines and vehicles, they build elaborate constructions all over Fraggle Rock, like towers, buildings, roads and bridges. Doozer constructions are the Fraggles' favorite snack, and they love to eat the buildings that the Doozers build. The Doozers don't mind their buildings being eaten -- if the Fraggles didn't eat the constructions, the Doozers would run out of building space!
