Greetings; Has anyone reverse drawn a schematic for the cnc4pc C41 spindle controller?
For some strange reason I am only getting about 8 volts P-P out of the LVT847 optoisolator, whereas I was under the impression it should be a nearly 12 volt P-P swing at that point. Board input 12 volt is 11.89 volts. This 1HP motors controller needs a full 12 volts for wide open. So I'm only getting about 750 revs in high back gear, 300 in low range. Thanks all.
