    Hello, I have a bit of a problem with my Ramps 1.6+ and steppers.
    Connected everything accroding to:
    https://www.v1engineering.com/auto-square-dual-endstops/

    But.. While homing one of the X motors (X1 on linked picture) doesn’t move at all It’s stuck in one place. Pushing it helps to get to its destination.
    Tried everything to fix that, swapped X with Y, same problem with one of Y motors, swapped drivers and still same problem, even swapped Ramps to brand new one.. still one of motors is not working as it should. I have checked wires with multimeter everything is ok.

    I am using Repetier-Host v2.1.6, firmware on arduino is from github preconfigurated for ramps with dual endstops.
    Power supply has 12v output, connected it only to the + – input, not the Heatbed but I dont think that’s the reason since im only powering 4 steppers, Z axis isnt connected at all. My steppers are 3,1V 2,5A with DRV8225 set to 0.750V (+/- 0.020V).

    Did a small gcode run, It seems like the motors are working fine, problem only occurs on homing.

    Seems like x_min is TRIGGERED, Checked for shorted wires or connectors, there were none.

    Quickest thing is just to swap the pins in the firmware to another endstop signal pin.
