    I should have bought this one first

    I have plenty of experience with stepping motors, having designed a few drivers myself from scratch. With drivers available under $100, there is really no longer a reason to waste time and energy designing my own. This is my first "digital" stepper driver, and I'm very happy with it. I first tried to "cheap out" with the much-less-expensive TB6600, which did not even come close to the far-cheaper-still Pololu drivers on my super-cheap RAMPS board.A stepper driver is essentially a constant-current power supply that works by rapidly switching power on and off ("chopping") as the winding current hovers just above and below the current setpoint (selected by DIP switches). This allows high voltages to be used for fast risetime (giving you more RPMs and torque) but without overheating the windings with excessive current. A digital stepper driver, I assume, replaces the typical analog chopper circuit with a DSP, which performs the same function in software rather than using op-amps and an analog oscillator. Software is probably more robust when it comes to glitch-resistance and noise, but probably also has the vulnerabilities you'd expect putting a DSP in a high-RFI environment.These drivers work better with linear unregulated power supplies (like a simple transformer/bridge rectifier/filter) than with a switching power supply, because a switching supply will limit the availability of power when it's needed most, at the instant the motor starts to move. But I tested mine with a switching supply and they work fine. Using a large filter cap on your power supply will help performance in the same way a "boomer cap" can help an underpowered car stereo hit powerful bass notes.My test setup is a 26V 15A power supply, an Agilent 33220A signal generator (to provide a step pulse input which ramps up slowly from zero to establish the maximum running speed), the driver, and a variety of motors ranging from a tiny NEMA 17 to a big 8-pound motor pulled from an industrial robot. I check current in standstill and during acceleration using a current probe. No shielding or filtering is used, because I want to see how good the shielding and filtering is inside the driver under adverse conditions.Motors connected to the competing driver skip steps and make alarmingly loud grinding noises, even when standing still. Not one of the motors performed adequately at any RPM or torque load. When I dropped the DM542T into the same setup, ALL of my motors worked fine, with no noise or skipped steps, produced boatloads of torque, and ran cool and quiet, even down to 12V.Stepping motors should not be noisy. Listen to a quality 3D printer and decide if it sounds more like a flute, or more like a bunch of gravel pouring out of a dump truck. If it's the latter, it's almost certainly because the driver is poorly designed. All that extra noise is power being converted into heat and noise instead of useful work.I ordered three more of these for my CNC setup and tossed the TB6600's right in the recycling bin. I would not recommend those cheap drivers even for a science fair project or a homemade 3D printer, because you'll spend most of your time trying to fix problems you shouldn't have to deal with. If you want to save money and you don't have a giant motor, use Pololus or something else, but if you want good performance out of medium (or even large) size steppers, the DM542T probably won't disappoint you. You can spend a lot more on something like a geckodrive but you won't see a boost in performance commensurate with the 300%-500% price increase, unless you have very specific torque or voltage requirements.

    Works well with Smoothieboard / MKS SBASE

    I'm very happy with these drivers. I bought three of them to drive the two NEMA-23 steppers for the Y-axis and for one NEMA-23 stepper on the X-axis. I switched from using the built-in drivers on my Smoothieboard clone, which I suspected were not driving the motors adequately. Once I switched over, this motor driver was much quieter and I am now getting consistent results.However, there are a few lessons learned along the way. First of all, there are some rather odd wiring suggestions floating around for connecting these to the smoothieboard. The simplest, most obvious solution is to take the 4-wire straight pin header with the TTL signals (either 3.3V or 5V depending on how your board is set up) and connect each axis to your drivers. In my case I started with the X axis which has P0.4, P2.0, P0.5 and GND (using the Smoothieboard pin numbers) and connected GND to all three of ENA-, DIR- and PUL-; connected P0.5 to DIR+; connected P2.0 to PUL+, and P0.4 to ENA+.The 4-wire stepper motor leads go on A+, A-, B+ and B-, and I ran power directly from my 24V DC power supply to the power inputs.The switch settings are just slightly confusing. You will have the Smoothieboard either configured for 16 microsteps or 32 microsteps. The entry in the switch setting table for 32 microsteps is 6400 steps per revolution. Forget about the 400, 800, 1600 numbers and just look at the microsteps to find your switch settings. Peak current for my motors is 2.8A so I selected that for current.There is ONE change you need to make in the Smoothieware config. The pin setting for direction needs to be inverted. Just add ! after it like this (for the X axis, aka alpha):alpha_dir_pin 0.5!This has to be done for each axis motor being driven by this driver unit.The Smoothieware configuration has a default of 1 microsecond for microseconds_per_step_pulse, which seems too short for this driver. It's actually just right, as observed on my oscilloscope. It comes out to around 3-4 microseconds, and this driver triggers on the leading edge, so the Smoothieware settings should not be changed.If you have dual Y axis motors, you just need to connect the inputs in series. The motors should be hooked up the same as they were when connected directly to the Smoothieboard, which often has them turning in opposite directions. In my case, P2.1 goes to PUL+ on each of the two drivers, P0.11 to DIR+ (and needs to be inverted in the config file), P0.10 goes to ENA+, and GND goes to PUL-, DIR- and ENA- on each of the two drivers.Do not use the GND from the signal header for the power connector. Both the +24V and ground should come directly from your power supply.Basically, I should have done this in the first place when putting my CNC together. These drivers are good value. There are apparently also a number of cheap knockoffs which might be slightly cheaper, but I would buy these again.

    The ability to adjust microstepping gives great flexibility

    I put a fourth axis on my Geckodrive driven CNC router but the Geckos only do ten microsteps per full step and that didn't give me enough resolution to accurately divide the rotational axis that really didn't have enough gearing (only 3.5:1). By running this driver at 25,000 microsteps per revolution or 125 microsteps per full step I got enough resolution to make it work. Driver is as smooth as the Geckos which up till now are the best I have used. Now I can tell my 4th axis to to do 360 degrees and it actually does 360 instead of 359.5 or 360.5 which was happening with the Geckos because of their lower resolution. Also this drive clearly has some of the anti resonance measures incorporated in the Geckos, despite their seeming simplicity steppers are finicky beasts to drive well and this board nails it.Judging by how fast this driver will spin the steppers it does like the Geckos and at some point as it goes up the speed range changes from microsteps to full steps.I tried one of the cheaper TBA something or other drives and it made the motors noisy and lost steps to the point I though there was something mechanically wrong with my machine and spent days checking, tightening and adjusting everything. I wish I had bought this first.

    I bought a cheap driver for my NEMA 23 upgrade I was working on, but it got really hot (50C) and made the motor noisy. Yes, it was rated for the NEMA 23 but just had so many problems. So, thought I would buy the name brand that matched the motor and while it was 3x the price, this driver is amazing. It can microstep to 1/128 instead of the usual 1/16 maximum and doesn't get hot. You do need 20-50V to power it, so I used a 24V power supply. Didn't realize that until after I got the unit and had to order a 24V supply, but the extra effort was well worth it! Highly recommend.

    Sehr guter Treiber, leistungsstark, ohne Schrittverlusste, laufruhig.

    Ich gebe hier ein Bewertung ab die sich auf den STEPPERONLINE DM542T und den DM542 von SEAFRONT bezieht.Beide Treiber sind relativ Preisnah der Stepperonline DM542T kostet aktuell 32 EUR und der Seafront DM542 25 EUR.Ich habe beide Treiber an meine CNC getestet, als Software habe ich ESTLCAM 11.241 genutzt.Beide Treiber funktionieren sehr gut. Vorher hatte ein TB6600 im Einsatz, diese Treiber sind laut, ruppig und verlieren immer wieder Schritte.Ganz anders verhalten sich diese neue Treiber.Ich kann teilweise schon extreme Beschleunigen einstellen, perfekter Lauf.Die Motorren sind mit diesen Treiber sehr leise und laufruhig. Wobei der STEPPERONLINE DM542T bei mittlerer Geschwindigkeit leicht pfeift.Das ist auch der Grund warum ich mich für den günstigeren DM542 von SEAFRONT entschieden habe.Das Verhalten ist bis auf das Pfeifen sehr identisch.Wer jetzt meint, die Treiber sind bis auf den Kühlkörper gleich, der irrt.Ich habe durch die Gehäuseöffnung sehen können, dass die Treiber sich zumindest von den benutzten Bauteilen sehr unterscheiden. Es ist also nicht einfach ein und der gleiche Treiber.Fazit:Beides super Treiber, bis auf das Pfeifen. Einzig der Preis ist beim DM542 von SEAFRONT besser.

    Absolute Top ware

    Aber diese Treiber als Upgrade für meine China Treiber gekauft. Vorher dm542 China Ware. Bei Spindel TRC mal 3 war bei 520mm pro minute Ende der fahnenstange. Da ich zwei Motoren bei der Y-Achse synchron Betreiber verstellte sich das Portal... Sehr laute Fahr Geräusche und Resonanzen.... Dazu passen wenn er von einem arduino Uno auf den Klemmen Adapter von Estlcam umgeschrieben... Was soll ich sagen das ist eine ganz andere Welt Wahnsinn... Unterschied wie Tag und Nacht. Sanftanlauf keine Geräusche mehr und bei den Seiten Spindeln verfahrgeschwindigkeiten von 1500 mm pro minute.. die Betreiber sind jeden Cent wert.... Bedüsung verfahrgeschwindigkeiten kann ich jetzt doch endlich meinen Laser betreiben..top

    Sehr gute Schrittmotortreiber

    Nachdem ich meine China-Treiber durch einen Floatenden Zustand (also ohne USB Spannungsversorgung) mehr als schnell zu Fall gebracht habe, habe ich nach gutem Ersatz gesucht und habe diese Treiber gefunden.Fehlende USB Spannungsversorgung stecken die Treiber einfach weg.Auch nach mehreren Wochen Betriebszeit kann ich die Treiber jedem weiterempfehlen.

    Funcionan bien y son fáciles de instalar

    Ya habia comprado uno antes y compre dos mas para construir un sistema de tres ejes. Este driver funciona bien y a la primera tanto con Arduino como con Mach3. Anteriormente compre algunos baratos que no funcionaron.
