General Mach Discussion / Re: BOARD PROBLEM HELP REQUIRED
« on: April 24, 2009, 06:27:11 AM »
Hi, just a quick update...got replacement board and it is doing exactly the same as the original one...
when i send a command to z axis the other two motors vibrate but z does nothing....
anyway put tester on motor output wires and got the following readings, hopefully it will help one of you guys to tell me whats wrong and how to fix it...
on the working motors i get:
red-yell = 3v
red-green = 3v
red-blue = 4v
on the z axis that wont work i get:
red-yell = 0v
red-green = 5v
red-blue = 4v
Any help is much appreciated
cheers
