Duet2 Stepper Driver Current Limit
wilriker last edited by
I read on an old thread that the current limit for the stepper drivers was increased after implementing some changes in RRF to keep the driver cooler.
Purely out of curiosity I would like to know if there are any more changes planned/possible to further increase the driver's current limit.
Probably not. In theory, if I could implement standstill current reduction then we could increase the current some more, perhaps to 2.8A. Unfortunately the TMC2660 doesn't handle it automatically, and implementing it in firmware in a way that is totally reliable is difficult. I guess it might be possible to increase the current just in the middle section of high-speed moves.

@dc42 is the 2A driver limit (and config setting number) peak per coil at a full step position, or RMS?
The limit is 2.4A (increased from 2.0A some time ago) and it is the peak value per coil.
