Suddenly started printing slanted?

  • 3D Printer Model: i3 Anycubic Mega S
  • Slicer: Ultimaker Cura
  • Problem description: Recently my printer has been printing terribly for about the first 4mm or so upward and then it is completely fine. This has come out of the blue, I’m not sure what has caused it because it worked fine when I used it about a week ago. It does this with and without the raft. I’ve got an Anycubic i3 Mega S and am using Ultimaker Cura. Any ideas on how to fix this consistent problem? Thanks.
