@BoozeKashi: No, that never happened before. I printed different tall things over time. Up to 20cm height, without problems. Yesterday I printed 3 parts for the marble machine. The spiral is 11cm tall and it looks relatively good. On the left part there are again gaps between infill and outline (55% outline overlap in S3D).
I printed this with 3rd party silver filament. No clicking sound at all. 1st layer 220, 2nd layer 210, 3rd layer and upwards 200 degrees.
I was very happy in the past with my used glue stick. It did a great job.
I think the result of the spiral is nice because the printhead doesn't need to move long distances. During the print of larger objects the wobbling of the carriages is very noticeable. And that wobbling is a pretty new behavior of my Flux.
The alignment of this 3 parts looks pretty kinky, sorry for that
