Cloudray 2-Phase Stepper Motor Driver DM542S 1.0-5.0A 24-48VDC 1/128 Micro-Step Resolutions for CNC Nema 17, 23, 24 and 34 Stepper Motor for CNC Engraver

The most important thing about this driver is how well it drives a stepper motor. There is no noise as a result of no vibration even when I set the amperage that would overdrive the motor. It is also very convenient that the rms amperage is shown on the dip switch table. These drivers are so smooth and quiet they are really worth the additional money. I have replaced all of my TB6600 with these. The TB6600 are really not good for a series of reasons. I definitely highly recommend this driver.

Has performed very well. Using to drive a large stepper. No problems so far using a 48 vdc supply on a high torque stepper. Control is great.

This is the most cost effective stepper driver I've found that can handle higher voltages. On my machine, it outperformed $180 drives. It doesn't require any software tuning to take full advantage of the driver, so it was very simple to install.

I was shocked. Yeah, they will run hot since you're pumping constant current at all times, but oh my god, finally a simple controller to replace a $2k servo drive.

This is an excellent driver for medium to high current motors. Steps down to 25,000 steps/rev, simple wiring, good quality housing ("Voltage" is misspelled on the pin map, which is a bit awkward), runs motors more quietly than a TB6600 based driver.Problem: does not accept 3.3v signal. It is completely unresponsive. This is contrary to the documentation provided:"Signal Level: 3.3~24V Compatible; Serial Resistance， Not Necessary for The Application of PLC."This is not an issue if you have a bi-directional level shifter, or are handy enough with basic electronics to wire up a 5v line with transistors, but without these mitigations, my driver is non-function at 3.3v.
