Topic: Press head Collides against left wall

When I start a print the head jams against the left side of wall since today. All worked well in past month or so.
So Jams against left wall then bed goes up and collides against the nuzzle.

When I press Home X manually in the Soliprint program head only moves an inch or so to the left.
I go on pressing Home X - it moves an inch each time, until it starts colliding into the left wall.
It seems the problem is X axis doesn't work properly anymore.
i.e. X axis doe not move the head to the right, always left.
Can someone advise How head moves  when you press Home X manually?
Any idea what I could do?
Here is a video of the same issue I have:

Loose broken or disconnected wires to the stepper, a bad driver for the x or a bad disconnected home switch for the x axis. check for loose connections do you have a meter to test the limit switch.

Re: Press head Collides against left wall

Figured it out.  Here is the fix in case anyone encounters the same issue.
The cable on the X  axis switch got unsoldered.
Soldered the three pins back and it works again.
Amazing that the plastic case is not glued to the board as well. Only the solder points holds the case to the board.
Definite point of rupture sooner or later.

Why is the x axis endstop on a PCB?

Re: Press head Collides against left wall

My connector was glued to the pcb. Mine had the exact same symptoms. Ended up being a broken wire about an inch from the connector. I ended up replacing the wire all the way to the motherboard and soldering directly to the end stop pcb. It appears the wire they used isn't up to the task of constant flexing.
