DM542T Digital Stepper Driver 1.0-4.2A 20-50VDC for Nema 17, Nema23, Nema 24 Stepper Motor
The DM542T is a fully digital stepper driver developed with advanced DSP control algorithm based on the latest motion control technology. It has achieved a unique level of system smoothness, providing optimal torque and nulls mid-range instability. Its motor auto-identification and parameter auto-configuration feature offers quick setup to optimal modes with different motors. Compared with traditional analog drives, DM542T can drive a stepper motor at much lower noise, lower heating, and smoother movement. Its unique features make DM542T suitable for high requirement applications.
Key Features:
- Input voltage 20-50VDC
- Anti-Resonance provides optimal torque and nulls mid-range instability
- Motor auto-identification and parameter auto-configuration when power on, offer optimal responses with different motors
- Multi-Stepping allows a low resolution step input to produce a higher microstep output, thus offers smoother motor movement
- 15 selectable microstep resolutions including 400, 800, 1600, 3200, 6400, 12800, 25600, 1000, 2000, 4000, 5000, 8000, 10000, 20000, 25000
- Soft-start with no “jump” when powered on
- 8 selectable peak current including 1.00A, 1.46A, 1.91A, 2.37A, 2.84A, 3.31A, 3.76A, 4.20A
- Pulse input frequency up to 200 KHz, TTL compatible and optically isolated input
- Automatic idle-current reduction
- Suitable for 2-phase and 4-phase motors
- Support PUL/DIR mode
- Over-voltage and over-current protections

Excellent stepper driver better than the mini pololu MCs, if you want better results for 3d prints or accuracy for a cnc machine, this driver is a good choice for your project.

Amazing difference. Purchased this to replace an old TB6560. I read good things about this driver and I decided to give it a try.
My home built CNC router was loosing steps occasionally and it was loud. There was a lot of resonance in the stepper and ball-screw system.
This new drive set to the same microstepping (1/8) and the same current setting made a huge difference. I can barely hear the motors when homing at low step rate and very quiet at higher speeds. The anti-resonance and wave shaping circuit must really work as advertised to make such a difference.
Big thumbs up.

Easy to use. Runs cool. Read the manual, set the switches, wired them up and have not had to do anything else. 60+ running hours on 3 drivers.

Works great, barely get warm running for an hour on 3A. Better than G540

This product works great. Normally i would like to give it 5 star but i have a mobile application for what it is essential to plug and unplug the wires. Here comes the big problem. The two voltage wires and the four motor wires are connected to the same green six-screw plug. Whenever i need to unplug the six-screw plug from its terminal, i have to unscrew the two voltage wires to take the cables out from its case through different holes in the case. There are three solutions for this problem:
1. The fast one
Take a cutter knife and cut out the wall of the 2-pin Enable terminal at the border of Dir + Pul. Use the six-screw plug for Ena+Dir+Pul and use the two-screw plug for power and the four-screw plug for the stepper motor. This way the power and motor cable can go out of its case in different holes.
2. The cheap one
Dump the six-screw plug and get one more two-screw plug and one more four-screw plug.
3. The best one
Get a driver what has the correct terminals to connect a six-screw plug for Ena+Dir+Pul, a four-screw plug for the motor and a two-screw plug for power. So every cable with plug can go out of different holes of its enclosing case.
