Is my V3.1 300 making too many Z adjustments?
Configuration: Stock RR V3.1 300, using Phaetus HF and Super pinda probe
Hi! I have a quick question about the Z adjustments my 3.1 does at the start of every print (when it probes 3 points of the bed, 3 times each).
It usually does that AT LEAST 2 times (sometimes 3) because the loerance is not 0.020000 at the first try, even though I don't even touch the bed after I'm done printing (apart from removing the PEI sheet to get my prints and putting it back on).
Is it normal?
How much does your printer do that?
Is there any other way to make that calibration with my current setup?
Would beacon/eddy change this situation by much?
Sorry for the amount of questions, I'd love to hear from you, any help is greatly appreciated.

(straight) Rear leadscew is wobbling
Hi! here’s the situation: I got a used V3.1 that had a badly bent REAR leadscrew, so I bought and installed the following replacements from the official RR store:
- new leadscrew (looked 100% straight, rolling it on a table showed no imperfections)
- new coupler
- new bearing to connect motor and coupler
- reprinted the pillow part on which the coupler sits (bc the previous one didn’t let the bearing sit flush inside)
After replacing all of the above, the situation got better BUT the leadscrew still bends a bit more compared to the other two. (see the two videos, it looks wobbly AND kind of erratic, sometimes it abruptly changes its position. I removed the upper stabilizer thing just for the videos.)
Could the motor be the culprit?
Is this normal for the rear leadscrew specifically?
Am I forgetting something?

VC3.1 300 fixable without taking it apart?
Hi everyone, I recently got my hands on a used 3.1 in pretty good condition, but I am currently struggling with bed leveling: it's at 0.5mm deviation now and I'd like to make it better
I TRIED FOLLOWING THE DOCUMENTATION AND THE VIDEO INSIDE IT, especially the part with the examples of gantry compensation by unscrewing 4 screws to move it (see photo), but it seems like the gantry barely moves when I do that?
I tried moving my front right corner down to compensate for the rear right being low, and the results only got slightly worse when I tried doing it (from 0.3 to 0.5).
So, is it possible to solve it this way somehow or would I need to disassemble it?
