Hello,
I’ve got this stepper motor and two sorts of drivers which are a4498(https://www.pololu.com/product/1182) and drv8825(https://www.pololu.com/product/2133).
https://www.pololu.com/product/2267
After getting this, I realized that the rated currents(1.68) is more than the driver’s spec.
Anyway I tested with current setup and DRV8825 didn’t work but A4498 worked correctly with 12V power.
So there are three main questions -
-
Is it possible or not working with DRV8825 with that motor? I followed your mention of “Our DRV8825 stepper motor driver carrier is probably the best option for this stepper motor.” in the motor’s page.
-
Do you recommend keep using a4498 with that motor with current limitation setup? Otherwise, should I replace into more appropriate motor?
-
I also tested with 0.4A stepper motor(https://www.banggood.com/NEMA-17-26N_cm-0_4A-Stepper-Motor-42mm-Two-Phase-Hybrid-Stepper-Motor-p-1115757.html?rmmds=buy) but it was not compatible with both of drivers. could you explain why it’s not working?
