I made some mistakes learning how to use the $300 Elegoo Centauri Carbon 3D printer, but it didn't take me long to make my first part.

There’s one that gives you a simple drawing program for making your 2D image, and then produces G-Code so that your 3D printer can extrude the drawing as a single plastic layer.

You can also define macros for real G-codes if you want. So, defining G28 would allow you to take over how the printer homes itself.
