Plz help with the random shift layer

Hi guys!
I feel really good with the simplify3d. But plz tell me what happened to this? I'm pretty sure it's nothing about my printer because it's on right position when I print with slic3r.

Well you didn't mention what printer you had, but there is a known bug in some old printer firmware versions that caused this problem. So the first thing I would recommend is updating your firmware and making sure it's a version from the last year or so.

If that doesn't work, let us know what exact printer and firmware you are using
