Homing mk1 z axis

Hello,

I’m having a problem with homing the z axis. I can jog the z-axis up to the sensor and it will trigger the fault and the red light is on. I unlock it, jog it down a bit but when I run the homing sequence it just crashes going up, the red light is on but it’s not stopping.

Of course it happens the day before I’m selling it.

Thanks!

Has this issue ever been addressed on the forum? I’m having the exact same problem. Also error 1 randomly pops up and my z-axis moves all the way down when i want to go to one of the corners. I have a longmill mk2.5 48x30.
