Hi,

parametrs seems ok.

I suggest setting the full-step speed value above the maximum speed (switching to full-step is required in very particular cases only) and adding a small mechanincal load to the motor shaft.

Please, check the IC is in HiZ state before writing the configuration.

Kind Regards

Enrico
