Describe your issue:
I have a RR Vcore 3.1 enclosed
As an extruder I am using an Orbiter 2 connected to an EBB42, but for some time I have been experiencing temperature problems, the Nema 14 motor of the extruder gets very hot, I don’t know exactly the temperature, I do know that you cannot touch it with your hands , and stop extruding.
I have tried to lower the current to 0.40, and with this something better, but even so it continues giving me overheating problems.
The engine is: LDO-36STH20-1004AHG(XH)
and the configuration I have for that motor, the one for the extruder is:
[tmc2209 extruder]
uart_pin: EBBCan: PA15
run_current: 0.40
stealthchop_threshold: 0
interpolate: True
sense_resistor: 0.11
driver_TBL: 0
driver_TOFF: 4
driver_HEND: 6
driver_HSTRT: 7
I’m not sure that the “driver_…” lines are correct.
Do you see anything that can be changed to prevent it from overheating?
