Re: fickle y-axis

Hi Mariss,

I am not as knowledgable about steppers as you, but with all due
respect, is not the sequence you described for a half stepping motor?
In fact, I am using a 200 steps motor and half-stepping, so that
would make it a 400 steps motor, that is, it should have 100 poles
per phase?

Regards
