Just seemed to stop working for no visible reason. No DC to motor at all
..
Ignore the red circle here, the culprit stuff is at the RHS of the circuit
Mains supplies into it seem sound at 245 v on my cheap multimeter.
Analog voltage input correct . But motor will just not start. (have tried a seperate input from rheostat which I have used to test before and still no go)
Have tried on both linux cnc , and also on Mach 3 (on seperate computers) and still no Joy
Transformer on iso board gives 2 x 120v outputs but nothing at all at outputs A,B,C, at the other end of the board, and of course all the electronics are totally beyond me.
Any ideas please anyone ??
