Usage: Power vesc with a current limited PSU set to low current to avoid blowing anything up. measure offsets first with nothing connected turn off automatic offsets Connect second current limited PSU between phase outputs (all shorted together) and ground of the first PSU. Set at e.g. 1V 10A current limit. You can also connect a calibrated current measurement device in loop. Run terminal command with the same current setting "calibrate 10" It will turn on each low side fet in turn and measure the average current then give the calibration factor defines to put in the hw config. Since this is a potentially dangerous command it might be best to gate it behind an optional define in the hwconfig?
