Stock Y-axis limit switch doesn't work; new switch makes homing fail

  • Hello, thanks for taking the time to read. I just got a V2 Pro with a 4.2.2 motherboard. I have had constant problems with homing failures, and it's the Y-axis every time. Now the stock limit switch doesn't work at all, nothing happens when it's hit, the bed keeps trying to move back and the motor grinds until I turn it off or the printer automatically halts. I've got a replacement switch and when I press on THAT the y-axis stops, moves forward a little as though it hit switch, and then Homing failed: PRINTER HALTED, Please reset. I am losing my mind. I've tried multiple firmware versions, I've double-checked all the cables, I've tried multiple switches. What is wrong?
