# Anycubic i3 Mega layer shifting

My Anycubic I3 Mega shifts every layer by a little distance making straight model lean to it's side by an angle.

For example, this white round blob should've been a straight up cylindrical shape, but it leans to the right for some reason.

Don't look at dirty table, it was clean at the start of printing.

When I was printing this model, I prepared it with Cura 3.2.1 slicer.

What could be causing this problem? How it could be fixed?

Update 1: I've tried lowering print speed from 50 to 25 mm/s in Ultimaker Cura 4.4.1. It didn't help. After another test print it seems like it's an X axis problem.

Update 2: Result after setting print speed to 10 mm/s and travel speed to 50 mm/s (same model, same ABS): Even such slight change to print speed as 15 mm/s still produces layer shifting.

• Hi and welcome to 3D Printing.SE! Are the belts tight?

• @0scar Hi! Thank you. Don't know if the belts are tight enough but not overly. How to know if they are? Dec 24 '19 at 23:51
• Do you have the same problem with a generic gcode file from Anycubic or with G-code produce by another slicer than the one you used? On mine, I use the Slic3r version by prusa (called PrusaSlicer as I had a Prusa printer before) and I just change (reduce) the speed (and some minor details like bed size) from Prusa i3 profile and it works correctly (no displacement between layer).

• @NeronLeVelu I will investigate this possibility. Thanks. Jan 7 '20 at 14:44
