Less than month ago I purchased from Cubexupgrade.com, Z-Stopper unit, and it works like a charm until today...
1 Week passed since my last print, and today when I tried the manual move, the print bed didn't go up, down woks fine

And surprise, manual move works again, obviously without Z Top limit, but I know the hardware (CubeX Board and motor) is OK, right?
If I replug the grey wire, again the print bed didn't goes up.
Any clue?? Need to print some pieces soon.

WTW another strange symptom that I never noticed, is if I move the carriage manually, the front +X limit and +Y didn't work, the carriage hits the structure with pain noise
