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.

The G code for the printer was generated by FlatCAM, a piece of software made specifically for cutting PCBs with a mill.

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.
