| + | 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. |

Project Objectives
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.
Project Development History
🙁 Sorry, nothing here yet!
What even is a ‛Doozer’?
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!
