  • CNC Shield für Arduino und den A4988 - CNC Shield for Arduino and the A4988

    By:wecapp 2017-06-05 10:29:52
  • I want to steer a Steppermotor with the Arduinmo. I use the extension - CNC Shield and A4988 as a driver. At Banggood I found both at a reasonable price. Unfortunately, the shield was poorly soldered and had to be reworked. Now Arduino and the CNC Shield fit together and everything works without problems. Unfortunately, inaccurate soldering work is not uncommon with products from China, but for the low price one should accept them. Ich will einen Steppermotor mit dem Arduinmo steuern. Ich benutze dazu die Erweiterung - CNC Shield und A4988 als Treiber. Bei Banggood habe ich beides zu einem vernünftigen Preis gefunden. Leider war beim Shield die Steckerleiste schlecht eingelötet und musste nachgearbeitet werden. Nun passen Arduino und das CNC Shield aber zusammen und alles funktioniert ohne Probleme. Leider sind ungenaue Lötarbeiten nicht selten bei Produkten aus China, aber für den geringen Preis sollte man sie in Kauf nehmen. Read moreHide
