Abrupt Z offset when printing in different C direction

I am printing a different material than plastic, but I think the problem can be applied generally. As you can see in the image, the print immediately stops after the curve when printing in opposite x direction. The sample lies in the corner at the zero point of a ratrig core 3.1 Do you know what could be the issue? I was thinking if it was a bed mesh issue than the print would gradually stop, and not immediately after the curve.
