Trying to figure out what’s happening on my y-axis as it’s behaving badly. I’ve had some electrical issues so rewired my x and y axes a few weeks ago. Everything’s been working fine until recently when my y- axis stopped homing unless it was less than 100mm from the home position.
I’m running a primo on a MKS gen L board with dual endstops. I can fast-move and jog the y axis in any direction (faster than a homing love) over the entire length of the cutting area (including a 500mm fast move), but when I try home the one motor will not engage. Switching the motor connections on the board changes which motor is impacted implying it’s a board issue. I’ve tried disconnecting the endstops and that’s not working. I’ve also swapped stepper drivers and tested, but no joy. Considering replacing the motherboard but hoping for an easier/faster solution. I’m a bit stumped so any suggestions welcome.
