New XXL Shapeoko set up - initialization fail
here’s a fun one I discovered after several steps of head banging…
Finally realized why my initialization and homing won’t work even though all motors are connected and all limit switches are working.
When my homing starts, the Z axis starts going down instead of up. It then of course does not find the limit switch, and declares the limit switch missing, and quits.
So why does the motor go the wrong way? The Z carriage and plates are all installed in the right direction. The wiring has been double checked and is connected to the motherboard in the only way possible (BTW I cannot for the life of me understand why the wiring harnesses leaving the motor and leaving the motherboard are 2 different sets of colors! What fresh hell is this?)
I am left with only one conclusion: this motor is wired wrong. Or the motherboard wiring is wrong. But if that is the case, then all my motors are backwards, because they are all wired the same way. But I won’t know about the X or Y until it gets past the Z step, which I can’t do with the motor going the wrong way.
