The proximity sensors are NPN and on the i/o screen when triggered the green light goes out on the i/o monitor and a green light lights up on the middle row function monitor to the correct axis association. This seems to work just fine.
Now the interesting part...
When I turned it all on today, I forgot I left the g540's charge pump switch in the off position yesterday when testing everything again. To my amazement, I was able to clear uccnc software reset and move all axes correctly.
At this point, with it all working, there was no light on pin 15 in i/o like there was in the screen shot above. So I decided to switch the g540 charge pump switch back to the on position to see if uccnc would reset and stop. It did not and continued to function normally.
Next was to test the e-stop. Once I pushed this everything stopped, and the software went into reset mode. A state change was noted at this point in time on i/o diagnostics screen.
However now with it triggered, when pulling the e-stop back out to reset, the software was again stuck on the same unresponsive reset loop as originally. No movement was possible.
Also of note, the state change light was not indicating estop on/off at this point, like before. Basically it did not recognize it.
So, what are your thoughts on how to proceed?
Thanks,
