Hi All,
All done building my McWire, and now I'm almost done hooking up the electronics, but I've run into one thing I can't figure on my own:
For the 3-Pin wires going from the opto-endstops to the stepper driver boards (to Min and Max) - I can't find any documentation or clue or anything that tells me which side is power and which is ground (closer to the edge vs. toward the center of the board -- I got that the middle pin is the signal).
Multimeter obviously doesn't help, and the code I wrote to try to figure it out doesn't seem to be working either.
Thanks in advance for any help!
Cheers-
balm
