I just started playing with the command line tool TMC428demo, as it is more usefull to make a stall profile on a real machine (with limited axes ranges).
However, I don't see any option to change the microstep resolution. With the GUI based stall guard profiler I used the following parameters to get a profile in the range of 47.68Hz to 953.67 Hz (full step equivalent frequency):
1/8 microstep (USRS=3), PULSE_DIV=3, Vstart=25, Vend=500
But the TMC428demo allways starts with USRS=4. Is there a way to change it? And what about Amax and ramp_div? These parameters are not set explicit in the GUI version of the SG profiler.
With kind regards
