It does, not sure where you got that idea.
All of this has nothing to do with the original topic.
@brent113 because i see the temp stablize and not continue to swing and thought bang bang kept swinging (cause i believe what i read on the internet).
only on topic in that it can cause patterning on the z axis - yup its clutching at straws.
Now I got some time and adjusted the wheel distances of the carrier by loosing the allen screws and turning the eccentric nuts as described here to get a nice fit between the guides. I did this for both Z modules and the X module. I have found the allen screws in the X module to be loose at first. Moreover, I was able to change the distance between the wheels on both sides of the X module carrier without turning the eccentric nuts, just by moving the allen screws. Is this normal? Or is my carrier module damaged?
In the end it took me around 4 hours for everything. Taking another 2.5h to print the initial object again with the same firmware version and same Gcode just to find out that the helix is still present but with a larger pitch now. My next step would be it interchange one of the Z modules with the X module to see if this makes any difference. But probably not before new yearâŠ
Any other ideas or insights on this in the meanwhile?
I was able to reach the support. They first exchanged one linear module and after that a second one. The issue was a loose carrier on the left Z axis module. The helix pattern displacement was amplified by a second loose carrier on the X axis module. I did re-adjust the eccentric nuts but it seems that the shaft for those got damaged. Maybe. Anyway, I was not able to fix the issue that way. Nevertheless, I have a working machine again now after four and a half month 
. After exchanging two linear modules.
There is definitely room for improvement on their carrier designâŠ
