Mach3 Spindle output stopped working
« on: July 24, 2016, 11:37:13 PM »

Just fired up the lathe to do a bit of work and the spindle control has gone. It has been working perfectly fine for about the last 2 years since I put in a VFD to control the motor. Chased the issue all the way back to the pinouts on the parallel port and there is no 4.3v when I turn on the spindle. If I change the same ports that I use for the spindle to say coolant output it switches on and off but when I go back to spindle there is still no output. It seems to be a software issue. Any ideas?

Two thoughts come to mind…

It could be an accidental change to your setup – perhaps go to Operator / Restore Settings, follow the onscreen instructions to go back to an earlier set-up and see if that solves the problem.

Alternately it could be failure of that particular pin on the parallel port – perhaps change your settings, and wiring, to use another pin (assuming you have an unused output pin available).

Success consists of going from failure to failure without loss of enthusiasm.  Winston Churchill.
