It’s an oddly clean waveform for something not right. The only thing I can think to check is that you have the motor pole pairs set right (half the total number of rotor magnets).
Open loop mode generates voltage waveforms. It can be helpful to run that and plot out the measured current waveforms to see how closely they match. I got different waveforms at each speed when I did it. Not sure what to make of that. Gooser: a 4-in-1 Lepton derivative - #94 by dekutree64
