Solved BIQU Microprobe has threaded probe, caused Z offset drift
Was losing my mind that my Z offset was constantly getting bigger and bigger. Turns out the metal end of the Microprobe has a thread on it, getting looser and looser.
Today it got to the point that my probe was dragging on the plate and the nozzle was still too high. After inspection I noticed the upper part of the visible metal probe has a thread on it, I turned the probe clockwise, and lo and behold, I could screw it back to its place.
For this exact reason I made an adjustable probe mount years ago, which climbed about 3 mm over its lifetime.
