DollaTek CNC Shield V4+ met A4988 stappenmotor driver board voor Arduino

Kijk op internet en je zal zien dat deze shield vol fouten zit.

Ok

Wow lately I have done nothing but trash Chinese crap, this is nothing but another Chinese piece of crap. The board is miss-wired. The jumpers for microstepping are supposed to pull the line high if you have the jumpers in place. Well cant do that if it is tied to ground. So out of the 8 possible choices you are supposed to have for microstepping you are stuck with low, low, low which = full step. In all there are about 8-10 bits of wire you will have to run to make it functional. Buyer beware. Also notice that the 5&4 star reviews are global and can't be read! What trash.

Sur les 3 drivers fournis, 2 sont endommagés et ne fonctionnent donc pasdemande de dédommagement, merci

1. Mikroschritte Jumper sind an Erde statt +V angeschlossen --> schwierig zu verbessern --> funktioniert sonst nur ohne Mikroschritte2. Mehrere Arduino Pins sind falsch angeschlossen --> Man muss finden welche es sind und jedes mal in GRBL ändern

googelt vorher mal danach, ist der letzte schrott
