Solved Z Axis Auto Leveling Failing?

Prerequisite Information
Filament Type - PLA
Extrusion Temp. - 210 C
Bed Temp. - 60 C
Bed Make-up - Borosilicate Glass; No Adhesion Agent

Recently, I've started noticing my prints failing more and more, and it's due to the auto leveling of the Z axis. I can tell this because the actual print itself is way above the bed, and during the auto-leveling process the Z portion just seems to go up, maybe 2 steps every leveling point. I suspect it has something to do with the Z endstops, but I wanted to make this post beforehand in the interest of time. I will record a video of the problem and update the thread with a link, thank you.

I only had to mess with them once, and that was when I was realigning them on the lead screws.

 

The wiring looks fine, I think the problem is the left switch. It appears to be sticking.

 

You could also use the M119 command from a slicer terminal window. That gives the status of the endstops. You can then play with the endstop and submit that command to see if it is seen as triggered or not. Just remember that the trigger logic is backwards with the Z axis on the Robo

 

I am currently have the same issue but intermittently about every 10 prints or so.
I've been just jiggling the cross beam up and down a few times rapidly and all is good for a while.
I have a spare ready when the jiggling no longer works.
