I’ve been doing some testing with various objects downloaded from Thingiverse (+ a few that I’ve deliberately drawn using an incorrect orientation).
When printing objects (downloaded or drawn) that lay flat on the print bed they print fine. BUT, problem I’m having, any object that I download and rotate ends up with shifting layers mid print.
The Velleman default CPU cover is a good example. It’s drawn face up, meaning it needs to be printed with supports, however rotated 180 degrees (face down on the bed) it needs 0 supports and should print in less time / less PLA. But, rotating it is somehow creating layer shifts.
I’ve tried using, MatterControl, Slic3r and also RepetierHost to slice it, with the same results each time which says to me that something to do with the rotation is the issue.
Are there any specific steps I need to complete when rotating an object? Obviously, an object which has been drawn on either the xz, or yz axis will mainly need rotating to print properly.
