@Danderger

a better controller board that lightburn supports for the diode laser

I don’t have any direct recommendations, but a recent discussion may be helpful:

Recomendation please

To run GRBL firmware on the STM32 microcontroller, you’ll need to use grblHAL Whey have a Webbuilder which makes the flashing process a little bit easier. (Though still not easy!) You will need to know the exact pinmap and some other variables. The manufacturer of your board should be able to send you a pre-compiled .bin file of the firmware and give you instructions on how to flash it to the STM32. I thought, you wanted to replace this board? Did you try to swap the stepper drivers?
