No issues, board is perfect.
Im telling you it’s the firmware because it all stopped working after updating that.
The board is also well over 10 years old by now. MOSFETs do die.
You’re flashed the same firmware onto the board that hasn’t changed in a decade, and has been used in others’ machines for 10 years without the issue you’re experiencing.
Everything points to failure in the hardware, not firmware.
There’s the possibility that flashing the firmware exposed a flaw in the hardware, like some segment of memory that was failing but could be read correctly, couldn’t be written to without error, now the right bits are wrong and it’s glitchy when trying to use it.
If I could just compile the firmware that I found online it would Help me to test. Can anyone tell me how to turn the raw files into hex using the arduino ide?
