    • My issue was indeed because of a probecore being way to low. Don't know how its use could have lowered it, don't think any clog issue would be able to unscrew the head around the thread so I guess that it was sold like this, and just barely OK that it worked during a pair of monthes and then triggered each time the height difference detection.   If so, that quite a Q-Check issue from Ultimaker.
    • I just changed the whole capacitive sensor assembly. wasn't to bad to change out in my opinion. I do not keep a spare on hand.
    • Thank you @ahoeben, that is a neat solution for my problem indeed. Never really used project files so far, but it seems to offer some useful functionallity.
    • I think it says not at the same height.   I recommend you watch the leveling procedure - just the first two tests which are different.  There are a few failure modes which are completely different and easily distinguished by watching:   1) Surface detected too early.  As it does the leveling it never even touches the glass.  This indicates electrical problem such as nearby interference. Do the leveling sensor test in maintenance and report back on the number it displays (< 8 is a pass). 2) Surface detected too late.  The test relies on the capacitance changing.  The surface isn't detected until the glass moves down without the nozzle moving up.  Visually you see it touching the glass and still moving down more on one core than the other and it's usually obvious.  It could be the springs are too tight on the print bed or too loose on the core but this is very rare. 3) Cores are truly different heights.  This more common than you might think.  They can vary.  If you look in the log file you can see what was measured.  The cores are supposed to be 1.5mm different height nominally with an error of only 0.7mm allowed.  It could be a bit of gunk on the nozzle tip that wasn't hot enough to squish flat during the procedure.  This is extremely difficult to measure on the core itself with a micrometer as it's the height from the tip of the core to how it seats inside the print head so to the 45 degree angled area of the core just above the heat break.  So if it's issue #3 I'd just try a different core on the right core.  Or left core.  Sometimes the lifting switch doesn't function so it measures the same nozzle twice which is of course a problem. This is the easiest of all things here to fix.   #1 is most often caused by electromagnetic interference by the front fan.  First distinguish the issue and then you can get advice on your particular issue.
    • This may work ok......added "Tree Support" and a "Brim".   The support should just "break-away" from the part with no problems....           CE3S1_Pineapple Grenade.3mf
