Why is my printed object not sticking to the print surface?
  • The print surface is not clean. Wipe the print surface with isopropyl alcohol (see Manual 3D printer Mike 2Chapter 14).
  • The print height is incorrect. Calibrate the height by following the print bed calibration (see Manual 3D printer Mike 2Chapter 8)
