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

thingiverse

This drawing robot is similar to the commercially available AxiDraw. It's powered by an Arduino Uno controller and a CNC Shield, using GRBL firmware. The approximate 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 assembled from two other people's designs. I added the improved pen slider and the controller enclosure. This drawing robot lets you 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
