STEPPERONLINE Digital Stepper Driver 0.3-2.2A 10-30VDC 1/64 Micro-Step Resolutions for Nema 8, 11, 14, 16, 17 Stepper Motor

The media could not be loaded. It was easy to wire a standalone test and confirm that the controller does what is promised. It allows microstepping and current limits for a smooth and precise drive.The setup is well displayed in a silk screened table on the case.It looks very professional for the buck.Strongly recommended

I've been using two of their models for several months running a custom assembly machine. These things are durable and easy to use.I drive them with a Rapsberry Pi with the GPIOzero library.Code them as an LED and use the toggle() command to step them.Using the Raspberry Pi requires a level shift from 3.3 to 5V. The Texas Instruments CD74ACT541 line driver chip works flawlessly for this. Just power the chip with 5V. 3.3V signals from the Pi go in one side, 5V signals go out the other to the stepper driver.

DM320T garbage Plastic case. My project is on a bench turning a nonloaded linear screw. This driver functioned for about an hour total time. Very lite use. It has a plastic case no heatsink. Dont waste your money buy one with a metal case.

Super quiet. I used this as a replacement for my Z axis of CNC router.It replaced TB6560 driver and made a huge difference. Mostly in sound. Very quiet. No resonance smooth stepping.My other review for DM542T used for X and Y says the same thing.Both made by stepperonline.

1.The enable line must be connected or it will not run.2.This driver has that annoying clicking when starting and stopping the motor. Seen this with other drivers when the holding current on the driver (DM542 has a high/ow on SW4) was set on low. That made the clicking go away. This driver; no such luck. Tried ALL current settings. Still clicks. The "click" is actually a small shaft turning CW or CCW before executing a step sequence; not good. Tried all current settings too.3.Additionally, we cannot trust any products from the Far East without being inspected. This driver has NO HEAT SINK on the MOSFETS. This might be a problem on a hot day and cause overheating. In addition, the housing is ALL PLASTIC; which does NOT conduct heat! Bad omission by mfgr to save pennies!4.Driver works great on 8khz microstepping with 4mm pitch ballscrew (4/8000= 0.0005mm .) If it would only go to 10k to work better with 5mm pitch ballscrews; (5/8000=0.000625.) Not evenly divisible. Driver makers, you need to make smaller units like this with higher current ratings! A driver with 4A output this size housing would be great!

I have never had a problem with Stepperonline drivers until I got this one. Connected everything up, no movement. Replaced with a different version of a Stepperonline driver (DM542T), the stepper moved fine. Replaced again with this unit, no movement. Read the manual. The manual states that the Enable connection can be left unconnected since the default is Enabled, just like my DM542T driver I used that worked. Just for kicks, connected the Enable to +5V instead of leaving it disconnected and the motor immediately moved and everything was fine. This unit does generate noticeable (but acceptable) stepper motor noise whereas the more expensive 542 did not.

No issues. installed very easy and works perfect.

It has to be a good drive. It supplies from 0.3 to 2.2 A peak current and it has microstepping. This drive could be a perfect match to my NEMA 17 motor, requiring 1.3 A current. But there is one problem with it. It has only 4 control terminals and one of them is common anode (+). For comparison bigger Stepperonline drives have 6 control terminals and can be wired with common anode or common cathode. My ZK-SMC01 controller, which I like, can only accept a common cathode (-) wiring. It means to me that driver and controller are not compatible.I went to Stepperonline technical support and asked how can I wire my controller and driver together and did not get any intelligent answer. My conclusion - smaller drives from Stepperonline are victims of cost cutting. They eliminated 2 control terminals and saved 2 pennies. Now the drive is no longer universal and I cannot use it. I will have to return it and buy a better one, which can work with my controller.
