Hello,
I am camped on DRV8825 Stepper Motor as they are employed with the ASTROEQ driver. The current is set using a VOM and a Phillps screw driver. My question pertains to NEMA 17 motors. The brand are from the StepperOnline shop.
The amps/phase =2.0
This makes the DRV8825 hot when the Vref is approximately 1.0. What I am finding is that when driving the motors (RA and DEC) at low speeds <600x within KSTARS and EKOS. Where this cuts is when fine tuning to get to a celestial object. The motors just stutter. I have one DRV8825 just quit on me. This is why I am questioning.
