STEPPERONLINE stappenmotor driver/Stepper Motor Driver DM542T 1.0-4.2A 20-50VDC voor Nema 17, 23, 24 stappenmotor

Affidabile e ben costruito

Haciendo la comparativa de un TB6600 frente a este DM542T, el cambio en cuanto al sonido es muy notable, no es completamente silencioso como puede ser un TMC2208, pero muy adecuado para este tipo de drivers.Tras unas cuantas horas de uso continuo apenas se ha calentado nada, en cambio el motor si lo ha hecho y bastante, de todos modos nada que no puedas esperar.Muy recomendable si estas pensando en sustituir tu antiguo TB6600

Controla perfectamente los motores, el único inconveniente que le veo es el tamaño de la fuente para utilizarla con motores pequeños, pero la resolución de los pasos y el manejo de corriente es excelente.

Ich habe mit diesem Treiber einen TB6600 (noname) ersetzt und folgende Vorteile gefunden:- das Gezwitscher des Motors ist so gut wie weg- der Treiber wird bei einem NEMA23 (nominell 4A) nicht mehr warm- ruhiger Lauf- geht auch mit dem 3.3V Pegel eines ESP32 zu betreiben (wenn man den 5V Schalter an der Seite aktiviertAlso gute Investition.

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.
