Dennoch ist die gesamte Elektronik dermaßen veraltet, daß man mit keiner üblichen, moderneren SW die Maschine betreiben kann. Die Maschine hab ich vollkommen neu aufgesetzt, ergo neue echte bipolare Motoren, passende Netzteile, richtige Linearschienen mit Laufwagen, neue Treiber, vollkommen neue Elektronik, ein richtiger Spindelmotor, EstlCam-Steuerung, etwas mehr Licht. Vorher hatte ich andere, billigere 542er Treiber drin, die deutlich lautere Laufgeräusche machten, unerträglich fast. Jetzt mit den DM542T sind kaum noch Treibergeräusche zu hören. Die Maschine ist jetzt wahnsinnig stabil, vollkommen neu aufgebaut mit allerhand coolen features. Der Tausch der Treiber hat sich absolut gelohnt. Review: Cambio notable frente a un TB660 - 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 ## Features - Industrial grade stepper driver - Suitable for Nema 17 and 23 Stepper Motor - 1.0~4.2A, 20~50VDC, Resolution 1/128 Microstep - Compared with other analog chip drivers or TB6600, it can drive stepper motor with much lower noise, lower heating and smoother movements. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B06Y5VPSFN | | Best Sellers Rank | #133,316 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #118 in 3D Printer Motors | | Brand | STEPPERONLINE | | Brand Name | STEPPERONLINE | | Colour | black | | Customer Reviews | 4.8 out of 5 stars 635 Reviews | | Display Type | LCD or LED | | Item Weight | 210 Grams | | Manufacturer | STEPPERONLINE | | Material | Metal | | Material Type | Metal | | Model Number | DM542T | | Operating Temperature | 45 Degrees Celsius | | Part Number | DM542T | | Smart Home Compatibility | Not Smart Home Compatible | | UPC | 714485410482 715624558829 715776647549 | | Unit Count | 1.0 Count | | Voltage | 5 Volts | ## Product Details - **Brand:** STEPPERONLINE - **Colour:** black - **Item Weight:** 210 Grams - **Material:** Metal - **Voltage:** 5 Volts ## Images ![STEPPERONLINE CNC Stepper Motor Driver 1.0-4.2A 20-50VDC 1/128 Micro-step Resolutions for Nema 17, 23, 24 and 34 - Image 1](https://m.media-amazon.com/images/I/61c8wFRoTqL.jpg) ![STEPPERONLINE CNC Stepper Motor Driver 1.0-4.2A 20-50VDC 1/128 Micro-step Resolutions for Nema 17, 23, 24 and 34 - Image 2](https://m.media-amazon.com/images/I/61PWmAwXxnL.jpg) ![STEPPERONLINE CNC Stepper Motor Driver 1.0-4.2A 20-50VDC 1/128 Micro-step Resolutions for Nema 17, 23, 24 and 34 - Image 3](https://m.media-amazon.com/images/I/51ekv-otLTL.jpg) ![STEPPERONLINE CNC Stepper Motor Driver 1.0-4.2A 20-50VDC 1/128 Micro-step Resolutions for Nema 17, 23, 24 and 34 - Image 4](https://m.media-amazon.com/images/I/61MidaukkVL.jpg) ![STEPPERONLINE CNC Stepper Motor Driver 1.0-4.2A 20-50VDC 1/128 Micro-step Resolutions for Nema 17, 23, 24 and 34 - Image 5](https://m.media-amazon.com/images/I/416r5J6n5hL.jpg) ## Questions & Answers **Q: Can this drive a 200 step motor?** A: yes, all this does is convert pulses into different voltage pulses (adjusts current) across the stepper motor coils. The driver doesn't care about the steps/revolution of your motor. You can adjust the number of steps per revolution (microsteps x stepper steps/rev). It is up to the users to convert number of pulses into revolutions of motor shaft if you care about absolute position or have a fixed pulse frequency and want a specific RPM. **Q: Can this drive 400 step / 0.9° stepper motors?** A: This controller is designed for a 400 ppr motor. You can also get much better than .9° resolution by setting the switches. On my mill I use the 800 ppr setting which is a half step or .45°/step. You then need to make adjustments in software or code for 800 ppr vs 400 ppr. I have not used it with higher than 800 ppr or 1/2 step so I don't know how it will work for you. **Q: Can this be controlled using a Raspberry Pi?** A: I would think with the appropriate hat it could. **Q: This is my 1st go at this. is the dm542t the best choice to run the 17hs24-2104s 92oz nema 17 motor?** A: idk what the best choice is , but these will run them.. id set the dip switches to low current ## Customer Reviews ### ⭐⭐⭐⭐⭐ Gute Treiber für DIY-Projekte im CNC-Bereich *by F***Z on 17 September 2023* Ich hatte mir eine alte, voll funktionsfähige ISEL MCP 2018 gekauft, die kosmetisch noch ziemlich gut in Schuß war.
