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 ## Frequently Bought Together - STEPPERONLINE CNC Stepper Motor Driver 1.0-4.2A 20-50VDC 1/128 Micro-Step Resolutions for Nema 17 and 23 Stepper Motor - 42 57 Stepper Motor Driver Controller Integrated Board Forward/Reverse Pulse Speed Angle Control Module PLC Serial Communication - STEPPERONLINE High Torque Nema 23 CNC Stepper Motor 114mm 425oz.in/3Nm CNC Mill Lathe Router --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.it/products/460823694-stepper-motor-driver-stepper-motor-driver-dm542t-1-0-4](https://www.desertcart.it/products/460823694-stepper-motor-driver-stepper-motor-driver-dm542t-1-0-4) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-11-12*
