## Questions & Answers

**Q: Can this drive a 200 step motor?**
A: yes, all this does is convert pulses into different voltage pulses (adjusts current) across the stepper motor coils. The driver doesn't care about the steps/revolution of your motor. You can adjust the number of steps per revolution (microsteps x stepper steps/rev). It is up to the users to convert number of pulses into revolutions of motor shaft if you care about absolute position or have a fixed pulse frequency and want a specific RPM.

**Q: Can this drive 400 step / 0.9° stepper motors?**
A: This controller is designed for a 400 ppr motor.  You can also get much better than .9° resolution by setting the switches.  On my mill I use the 800 ppr setting which is a half step or .45°/step.  You then need to make adjustments in software or code for 800 ppr vs 400 ppr.  I have not used it with higher than 800 ppr or 1/2 step so I don't know how it will work for you.

**Q: Can this be controlled using a Raspberry Pi?**
A: I would think with the appropriate hat it could.

**Q: This is my 1st go at this. is the dm542t the best choice to run the 17hs24-2104s 92oz nema 17 motor?**
A: idk what the best choice is , but these will run them.. id set the dip switches to low current
