# Why does the prusa i3 sometimes put the layer more right or left as they should be?

I often tried to print sth in the prusa i3-mk3 but in most time he prints at the middle of the object more right or left. Can someone please tell me why that comes?

• Can you add a diagram, or photo? Your question is not clear. Are the prints damaged, or just in an odd location? – Sean Houlihane Mar 15 '18 at 8:13

Moving on to why this happens in sth... I don't own a MK3, but I take it that sth is short for stealth mode, the new silent mode that has been widely showcased in reviews and articles on the printer.
