I do not have any opto endstops working any suggestions on where i may have gone wrong ??
I have them connected to the stepper driver board via ethnet connectors. if i connect an opto endstop to max the led is on permenantly if i connect one to min its off permenantly placing something in the beam does nothing ?
I have tried card knifes screw drivers but i can not make the led toggle any suggestion on what i may have done wrong ?
