@agz90 also make sure that you remove the Erase jumper before you command Bossa to flash the firmware.

@agz90 What board are the Z motors connected to? I would have expected them to be connected to the 6HC. What does M122 and M122 b124 (assuming your RRF36 has a can address of 124) report?

Thanks

Not sure if it will help but here's a RRF-36 Config for one of my tools,

@agz90 Try changing the PWM frequency next time ( Q ###) . I had a time with Sunon fans with auto-restart circuitry. Those are the ones with the letter A towards the end of the part number. Running them with a diode inline helps a little but ended up changing the fan out to one that was a bit more PWM compliant.

Thank you, thank you very much for telling me how to write it, in the above posts I wrote what my files contain.
