Re: LV8729 and OnStep

There is another issue to further complicate matters. If the supply voltage is 3.3v (vdd) as it is on the MaxESP2 then the maximum vref is 0.97v with the 0.1Ω resistors this is 1.0A current. Only if it is 5.0v is the max current (1.5A) achievable. This works for the steppers I have, I just set the pot to max and go. For others I am sure this will eliminate the LV8729 from their acceptable driver list.

I cannot say if this is true on all of the LV8729 chips, just reporting the issue on mine.
