Vref voltage TMC2208 for slim line motor

Hi,

I‘m using my Titan Aero with the slim line motor. With middle tension on the extruder, the motor stops very often. The extruder wheel is easily running without power at the motor coils. There is no resistance along the pathway for the filament.

I guessed for the reference voltage of the stepper driver. so I tuned the Vref to 1,2V output. But there is no change in the behavior. The motor gets about 44°C in about 5min of usage. Is that normal?

So what can I do to solve the problem? I‘m using TMC2208 original stepper driver.

Would be glad to get help.

Thx

Elisabeth
