Joystick control of a drawing pen, using more or less current reprap designs

Joystick control and a marker pen, drawing material-paper or (t Shirt) fabric or PCB

Age suitability: 3+

Problem:

No one retails a ready made system or DIY kit that has a pen to replace the hot end, thus making it suitable for 3-5 year old lego fans to build and use. The nearest current drawing alternative is the Egg Bot using the EibBotBoard electronics board and a Nema17 stepper motor to act as a torn-turner. Unlike a WatercolorBot or AxiDraw the frame is built by children, with adult assistance and the motors and extruder can be upgraded...

Proposal:

To use a standard USB interface device, like a joystick, mouse, trackpad or USB drawing pad, rather than an stl file, will require USB controller chip on the board. Hence the choice of CHIP as replacement for Arduino Nano.

Use a CHIP connected to SinapTec for control. Drawing end replaces ie Dremel with a (Marker) Pen held by screws in a metal tube, or with the Pen_Holder. Snap together designs like Snappy or ToyREP are ideal Repraps for the purpose and can easily be retro-fitted, or initially printed and made for this purpose. NEMA_Motor choice, 28BYJ-48 as used in the proven design for the ToyREP are cheapest motors, ensure that 12V version is used. No heated bed or hot end mean 12V 4A or less power should supply movement. Teacup_Firmware or Kamaq firmware on CHIP is currently being examined. These system are/sholud be more than capable of ie. drawing SVG files from PC interface, or web server (Kamaq based), acting as a 'photocopier' or more accurately 'printing press' or 'scribe'

The final model will be called SCRIBE.
