Unresolved Bed leveling question

Every other time the printer seems to hiccup during the leveling process at the beginning. As I am looking at the machine, it registers the from part of the bed. When it does the center, right, the head does not always come down and touch the bed. Not sure if it binding or something. After canceling and restarting, it looks fine, but still has the occasional hiccup. Attached is the bed side of the good print. Looks like the bed is still not level.

 

Home your bed, then raise it around 1mm off the build platform. Move the carriage from side to side ensuring it stays a constant height above the build surface.

After this is complete make sure your Z endstop switches are properly seated against the carriage. If needed loosen the securing screw a little and press the bracket up a bit. You want the carriage resting on the nut itself, but with the switch activated.

That should hopefully resolve the switch unseating early.

Otherwise some users use a rubber band to give it more pulling force to prevent the carriage from unseating early.
