I designed this after seeing other drawbots and wanting something I could hang on the wall and create large scale prints with. It can be run from many different controllers but I am using a Arduino with a CNC Shield and a grbl fork with servo support much like the other drawbots and many of the grbl settings are similar. I am planning on replacing the arduino and shield with a duet board for better results.

I printed most parts in PETG 100% infill with 0.20 layer heights and supports where needed. This uses V-slot rail and wheels from Openbuilds.

The Y Axis is 20x40 and the X Axis is 20x20. The belts are all run through the rail channels and it even has placement to hide the stepper wires and run a strip of LEDS along either axis.

I used a sg90 servo to move the pen and these stepper
