Looking for 3.4V 2.8A stepper** A: Coil voltage is 3.4V, the driving voltage is 24-48V. **Q: Do you also provide the screws that can be used to mount the stepper motor?** A: Sorry, we don't provide screws for the mount currently. **Q: Can i vary the steps of travel with an external pot input on this controller?** A: No. You question us confusing since this is a motor not a controller. This motor has a fixed step of 1.8 degrees you can’t change that from the controller. Not sure what you’re trying to do but you may want to look into a servo motor **Q: Can an encoder be attached to the back of the motor?** A: There are no features on the back of the motor that would allow the mounting of an encoder. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by J***K on 11 July 2020* I bought 3 of these and like the performance,easy to use and reliable. ### ⭐⭐⭐⭐⭐ Review *by U***L on 28 April 2024* Ok ### ⭐⭐⭐⭐⭐ Review *by D***R on 18 November 2024* Used it to put auto bed feed on my Grizzly lathe.
