Z wobble? Wave
Looking to get some thoughts on what might cause this ive had it on some prints and not others its not belt slipping to cause a layer shift but the whole print seems to wave on a very gradual pace and it returns to where it should be as it goes up. Just had a horrible print come out very wonky and 100% time to fix it now. Im taking the lead screws out to see how much those are bent if any, although it doesnt seem to match with the pitch so slightly confused.
Let me know if anyone has some ideas would be greatly appreciated!
It is in both directions, the nuts on the screws seem good along with the couplers..
Also its a vcore 3.1 enclosed 400mm

SOMEthing is very loose
So far have not been able to find anything loose anywhere belts z axis bed not really sure where else I should be looking
Can you feel any movement with the bed if you try moving it around? I don’t see how that is the case unless the bed arms are loose and even then. I suspect one or both of your pinion gears on the coreXY stepper motors are loose. Loose enough that is moves a little side to side on the flat spot on the stepper shaft but not fully loose were it moves all the way around otherwise you would see some major layer shifting. I had this happen on my vc3.0.
Thank you yea that was definitely something indidnt think to check the one had loosened off and started walking down so definitely a good thing to catch! Appreciate the help
awesome. Glad it was that. Z issues would have been more of a banding type issue where this was movement on the x & y. Reason I know is I had it happen on my VC3. I would recommend thread lock on those set screws or check them on some sort of regular basis. If you do thread lock DO NOT use the red permanent type as that requires heat to break the lock. I use the regular blue loctite bran
