I am trying set up my older blackbox for the Scribe Pen. I am having trouble flashing the firmware https://github.com/cprezzi/grbl-servo on to the blackbox. I have downloaded the Adruino IDE and it fails to compile, saying it can't find the grbl.h file. I am on Apple silicon which is creating it's own issues. I have flashed a .hex file via the terminal but it's not flashing. What should I try next?
Sounds like something in your Adruino IDE project setup - a grbl.h file is included in the zip download.
