3D printed Raspberry Pi Pico H-Bot plotter programmed in MicroPython capable of drawing on paper and burning wood with versatip.
Main purpose of this project was to practice Python programming, design something cool and understand basics of how CNC machines, Gcode senders etc. works. This project is probably a great starting point to learn about basics of any CNC machine, as it is very simple and code is very minimal. 3D printed parts are optimized for support less printing (most of them but not all) and can be printed out of PLA.

You don't need any special libraries or additional files, assuming you have Python installed you have everything you need. In order to upload script to Raspberry Pi Pico I used Thonny
Before executing the Gcode sender change port of your raspberry pi pico and also path to the file that you want to print To execute Gcode sender script simply change directory to where the file is located and type in the terminal:
python GcodeSender.py
