First time printing problems

Hi all,

I’ve just started witha snapmaker original 3D printer, using Luban 4.1.1 and noticed the following, on a normal print quality & with default settings:

  • calibrating the heat bed works fine, however prints seem to start 5-10 mm up in the air instead of on the bed. When recalibrating, the head moves to the correct level. Sometimes (50%?) it does it right.
  • When printing certain stl files, the printing shift by over 5 cm to the right back. The stl/Gcode looks fine in Luban

Any pointers would be welcome, as the manual & video are rather limited on any problems…

Best regards
