I didn't bother, since switching to a different infill pattern fixes it. Maybe if I get a chance, I'll recreate the problem and upload those for you.

Ok, I finally got around to at least grabbing the program file. Attached here.
Hey @CCLMakerSpace,
This looks like an enormously tricky challenge 🥴
I've been trying to see what you mean with trailing Zseam because mine looks like this in Cura 5.2.1:
Do you have a picture of how your printjob fails? Or how your zseam looks like?
If I were you I would switch to lightning infill for this printjob, depending on how seethrough your PVA walls are.
It has nothing to do with the zseam and I never said it did, sorry, I think you're misunderstanding the problem. It's hard to explain. Basically as the print goes on, the z POSITION drifts. As in, it's printing too low in the Z direction. It gets worse over time, until the nozzle is like several mm lower than the actual current height of the object, and keeps slamming into it. You can't see the problem from the project file.

Ohhhhh, I think I understand what you mean.
During your printjob the sphere starts curling up.
The warped material starts pushing against the nozzle and is limiting extrusion.
It's quite common in spherical shapes like this.
In that case, temperature control is super important!
You want to prevent that the printjob cools down to fast, and if it does cool, it does so evenly.
Can you limit the airflow around this printer? Move it away from a door, walking path, attach an airmanager or place a box over the printer?
Personally I would start experimenting with increasing the temperature of the bed, nozzle, and find ways to decrease the cooling. Maybe consider adding more walls or enable support. I would start looking for remedies against Warping and Delamination.
That's not the case. There's no warping visible at all, and it's happening even in the interior of the object. The difference in level is wayyyyy beyond what could happen with warping anyway. And it only happens on one specific infill pattern.
Edited by CCLMakerSpaceHopefully this crude MS Paint diagram will explain better. The pattern you see in Example 1 and Example 2 just keeps getting worse and worse if you let it, and then it eventually fails and exhibits the strange behavior I mentioned in the original post, about slamming the print head into the wall, and slamming the bed into the floor.

Hey @CCLMakerSpace,
Thanks for your report 👍
That's super interesting and I can imagine quite frustrating.
Do you have pictures of your zseam?
A project file would also really help. It contains the printer and settings we need for troubleshooting.
To save a project file go to File -> Save project.
