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 Inventables Easel to 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:
- Dremel Carver (or inexpensive WEN alternative) - possibly mounting the tool-end of the Flexible-Shaft attachment, to reduce machine vibration.
- 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 Vinyl Cutter replacement blade cartridges.
- Error creating thumbnail: Unable to save thumbnail to destination
  Filament Extruder and Hot-End for 3D printing, or

  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.

  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.
  - 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.

Tertiary Objectives

The footprint of the completed machine should not exceed 12.5" x 16.5" (to fit inside folding cart for easy transport)

Project Status

09/20/2019

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

09/18/2019

All off-the-shelf 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.

Funko Pop Doozer

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!
