shifting on same layer
Hi everyone,
I've just received a new MK3 with steel bed sheet. I had several problems about first layer sticking and I was able to solve them definetely only putting a vertex sheet on steel sheet. Anyway the biggest problem is this layer shifting showed in photo. It seems it's always the same layer every object I print. I've checked all screws and they are perfectly tighten, so what can I check more?
thanks
Re: shifting on same layer
have you observed what is actually happening a this height? is the printer re-homing? Is anything binding?
Re: shifting on same layer
I have exacly the same problem, i can't figure out what's causing this, it's driving me crazy
Re: shifting on same layer
If you guys aren't observing this when it happens, there's a very real chance this could be crash detection triggering a rehome and the printer not quite recovering. Try this with crash detection and filament sensor off and see if you still have the issues.

It happens in normal mode as well as in stealth mode, its not crash detection, it doesnt rehome, its always on the same height.
not a slicer issue cause it happens with slic3er and s3d.
Printing via SD card, also replaced the original with a brand new SD card, still happening.
It's also happening on different firmwares.
Also tried different Filaments.

If the problem is repeated at each print, you should search the error on any of the Z components.
Common mistakes are that the Z-screw covers are too tight, the Trapezoid nut is too tight or the Linear bearing or the Smooth rods are defective.
I do not think the problem is software related.

Re: shifting on same layer
I completely rebuilt the Z-Axis, and still the Problem is present
Re: shifting on same layer
At what level does the problem arise?
Is it when the printout changes from Solid bottom layer to Infill? What values do you have on Perimeters, Top and Bottom layers?

Re: shifting on same layer
So I was wrong, completely.
I switched to 3.1.1, and did some other changes to the Printer (replacing bearings etc.) that's where I started noticing the problems.
I then flashed to 3.1.2 and the problems were the same. so i reverted all mods, rebuilt z-axis, optimized the filament path from outside my enclosure. nothing worked. Finally I switched back to Changes in 3.1.1 b138 RC3.
My "layershift" occurs at the height where it goes to only perimeters / walls
Re: shifting on same layer
anyone managed to solve the problem?I disabled crash detection with no success.
I've seen sometimes prints have not this type of problem, I'm going crazy
Re: shifting on same layer
are you sure its layer shift and not where the solid infill (Bottom layers) finishes?
Try printing it with no bottom layers so its hollow maybe,
we have been chatting on a thread where that is happening on a benchy, its seems a common problem due to over extrusion on solid infill
