Ok, I just got my ultimaker, I have had some successful prints but after prints the layers got messed up, If I print a straight wall it becomes angled. Every layer mover over a little, on the z axis only. The prints are not just angled a little,a tall object looks like a flight of stairs :( .i watched the print and did not see anything slipping so it might be a software problem. (I'm using replicator g) however this only happens on the z axis. The extruded head is not touching the object. Btw this is more likely to happen on a print with a lot of gaps ( when it is not extruding).
Any ideas? :roll:
