Sometimes a layer seems to sperate from the rest of the print, what can I do?

The phenomenon is called “curling” and results in a print failure, it happens due to cold spots on your print bed.

Take the following steps:

  • first make sure you are preheating the printer for the full standard preheating time
  • increase the print bed temperature by 1 degree C (or more, if necessary)
  • decrease the laser scan speed by 100-200 mm/s if necessary
