Hi All
I have just joined your group and am having problems with a myford 7 conversion I have brought a optoport v3 breakout board from diycnc.co.uk and stepper drives from arceuro, on the breakout board there are 3 out puts for each axes gnd , xstep , x dir. I can understand that the x step and x dir go to pulse- and dir- on the stepper drives but can't work out where the gnd goes all the videos I've watched have common where gnd is and this goes to pulse + and dir + There doesn't seem to be a 5v coming from the gnd as anybody else come across this
All the best LEZ
