148x210mm Arduino CNC plotter using 28BYJ-48 stepper motors

I recently finished a project I had put off for TWO entire years after I initially couldn't get it to work. In this video I go over the pros and cons in the design of the almost entirely wooden plotter, and show you what to look out for when setting up your own Arduino CNC using unipolar stepper motors like the ubiquitous 28BYJ-48 with its associated ULN2003 driver board.

This way I may receive a small comission with no extra cost to you, allowing me to make more helpful videos!

Here's the modified GRBL I used: https://github.com/ruizivo/GRBL-28byj-48-Servo
The g-code extension Gcodeplot I finally settled on: https://github.com/arpruss/gcodeplot
And Inkscape: https://inkscape.org/release/inkscape-1.1.1/

These are irrelevant if you just want to make your own plotter, but in case you want to mess around with the code:
