I’m having trouble with steppers overheating with my default values from my Duet config. Here’s what I had them set to in Duet M906 X1700:1700 Y1800.00 Z1400:1400:1400:1400 E1000.00 I40 ; Set motor currents (mA) and motor. When I tried that in the Klipper config my steppers ran really hot. I diale…

The sense_resistor setting should match what’s on the physical board (or stepstick). One can verify the resistance of the physical “sense resistor” by reviewing the board (or stepstick) schematics. The sense_resistor config value isn’t tuned - it’s should be set according to the physical descripti…

Thanks, I’m really glad I asked. I think I have the current figured out but not the second part. I’m guessing the peak current is the same as the phase current in the specs which are phase 2amp. 2 x .707 x .85 = 1.2019 so current setting is 1.2. The second part went way over my head. Does it have t…

[image] chickenwoman: The second part went way over my head. Does it have to do with the sense_resistor: 0.051 ? Or do I need to do any other configuration. I’m using the default from the Klipper Duet config. Disclaimer: This is only my understanding and it is very hard to get reliable inform…
