Hello,
My ender 5 Pro seems to need its limit switch adjusted for whatever reason. The Bed is crashing into the filament tip head. I can see the limit switch is not yet engaged and when I try to set an auto home to compensate it cannot adjust and goes negative. Any ideas how to adjust the Z axis.
Edit: This issue is resolved I just had a blonde moment, and went in the wrong direction with the bed adjustments.
Can you share a picture of the limit switch thats not doing its job?
Can you do a manual level successfully?
Just a knee jerk reaction but how loose are your bed springs? If you tighten them down all the way does it still hit the nozzle?
I am really embarrassed to admit this. So I added supports and my bed became unleveled, so I thought Ill loosen the screens and that will lower the bed. Ya when I tightened them it works. I am so sorry, that was so dumb of me. You are right hahahaha
All good 
weve all made mistakes like that before
Hey, @GlennW don’t ever be embarrassed. I’ve been at this close for 15 years and the reason I mentioned it cause it happened to me. (and not just once)
There is also a little adjustment screw on the back of the bed so you can adjust the height as well as using the bedspring knobs to adjust
