Is it okay if a Bambu P1S Printhead is Wiggleable, or should it not react at all and never Wiggle? (lemmy.blahaj.zone)

I've come to Realize that it seams the Printhead on my P1S is Slightly lose. If I push up on it, it ever so slight moves up. I can Basically wiggle it. That also suggests why I have been having what has been assumed to be Bed Leveling Issues. If the Head moves up in the Auto Bed Leveling Process, all things get messed up.

To give a bit more Detail, I think its the Carbon Rods. A while back I made the Mistake of Greasing those, something I realized was wrong 2 Prints later. Ever since then when I clean the Rods, the Towel I use returns Fully Caked in Black. Messuring the Rods, what should be 10mm in size has become 9.75mm, which is probably why it wiggles.

The Question is, if this is even a big deal and if I'm right about the bed leveling issue theory. Its a 100€ Replacement, So I really wanna make sure...

First, how did you measure the rods? If you used a calipers, then the measurement is guaranteed to be inaccurate, (there is too much wishful thinking with a caliper). You need to use a real micrometer to get an accurate measurement for this job. Source: This old Toolmaker.

Second, I don't know the manufacturing tolerances for those rods, but I have to think it's more like +/-.01mm and not +/-.05mm. So I would assume you have irreparably damaged those carbon fiber rods by coating them in grease.

Third, yes the carbon fiber rods have absorbed some of the oils in the grease. This is not good. The good news is, if you contact customer service and talk to them, they can sell you a whole new xy carriage even though it's only available from customer service and NOT their parts store. You might even need a whole new extruder and bearings to banish all traces of the grease.
