I downloaded Tweekie's ParaMon today and it showed me that my optical isolator is not working.

I am trying to get my system running again. It ran for a couple of years then quit a year ago after I made some changes.
I am trying to use the diagnostics screen. Assuming the  LED's representing the printer pins are numbered from left to right, top to bottom, pins 4,5,6,7,8, are high. This correlates to y step & dir,  Z step & dir and one unknown.
I when I jog the steppers, no change is seen on the LED's (steppers are not moving either, but they are energized).
Using your logic above, I removed my optical isolator box and plugged the computer straight into the Hobby CNC Driver. Now no LED"S.
Any Ideas?
