The maximum speed of homing moves is much slower than for printing moves, because the endstops have to be checked. So if you use high microstepping, you need to use slower homing speeds. The 1.21RC firmware should allow slightly faster homing than previous versions did.

To check whether you are trying to home too fast for the microstep setting, first make sure the printer has a long way to go to home, then run M122, then home it. Then run M122 again and check the MaxReps field. If it is higher than about 50 then you are homing too fast.

For now you could try reducing the travel speed between probing (T parameter in M558) and if it is safe to do so, also reduce the dive height (H) and increase the probing speed (F). This will allow the heaters to stay on for more of the time during probing. Meanwhile I will look at suppressing heater fault detection when the heaters are suspended.

Good afternoon, I had all the commands on but the driver keeps warming up and as a precaution I'm going to replace it, thank you very much for all the help provided.
