When used on a driver which has the globalscaler field (tmc5160 and tmc2240), if StealthChop2 is used, the stepper must be held at standstill for >130ms so that the Oct 10, 2023 · Hi All, I spent some time today looking through and understanding how the TMC IRUN/IHOLD values interact with sense resistors and I noticed that there’s hard current limit configured as a constant in the definition for the TMC5160. I'll post my klipper config in case anyone else is trying to get theirs to work. # sensor. hi ms du lp ce jb mr tw df bm
