I am having the same issues on my Form 3. Tons of layer shifting. Direct comparisons to identical prints on my Form 2 show the Form 2 prints to be completely free of these issues.
Here is my post about it with pictures: Bad prints out of brand New Form 3
I contacted support and was told that I don’t have enough supports. I am having a hard time accepting this considering how well these printed on the Form 2. I have been nothing but frustrated with the Form 3 and am regretting my purchase so far.
