I can't find anything about this on internet. Also I can't really see a C value in my M569 commant.
this is what my M569 reports:
M569 P0: Drive 0 runs in reverse, active low enable, step timing fast, mode stealthChop, ccr 0x00053, toff 3, tblank 0, hstart/hend/hdec 5/0/0, tpwmthrs 1000000 (0.0 mm/sec)
