Writing & Drawing Robot Arduino Uno + CNC Shield + GRBL OPEN SOURCE

thingiverse

This drawing robot is similar to the commercially available AxiDraw. It is powered by an Arduino Uno controller and a CNC Shield and uses GRBL firmware. Aproximate cost to build this drawing robot is $83. The drawing robot receives G Code commands that are created by a drawing program called Inkscape. The robot was put together using two other people's designs. I added the improved pen slider and the controller enclosure. This drawing robot allows you to draw things in Inkscape and then plot them out. Below are the links to the software I used. Avanhanegem's design has a great tutorial on how to generate G Code within Inkscape and then send it to the drawing robot using Source Rabbit G Code Sender.

If yours is identical to this design, the G Code files should also work with yours. https://www.aliexpress.com/item/2017-DIY-drawbot-pen-drawing-machine-lettering-robot-corexy-XY-plotter-drawing-robot-kit-CNC-V3/32837711737.html
