Question / Error / Problem
Model loses adhesion to the
print bed.
en
Unwanted lines are visible on
the underside.
The print job is interrupted.
The first layers do not adhere
properly to the print bed and
loosen.
Unwanted lines are visible on
the underside.
Poor adhesion between the
individual layers, gaps in the
layers.
Display may show filament
feed errors.
Cause
• Print bed not aligned / leveled.
• The distance between the nozzle
and the print bed has changed.
Distance too large. If the nozzle is
too far away from the print bed, the
filament does not have any contact
to the print bed during extrusion
and, as a result, no adhesion to the
print bed either. The model slips
during printing.
• The print bed is not clean, for ex-
ample as a result of fingerprints.
Grease residue prevents adhesion
of the filament to the print bed.
• Unfavorable ambient conditions, a
draft, or cold air from air-condition-
ing.
• Model not flatly aligned in the CAD
software.
• Contact surface to the print bed is
insufficient for optimal adhesion.
• The model was not placed flat on
the virtual print bed in the SIMPLEX
sliceware. Model only has limited
contact with the print bed and there-
fore insufficient adhesion.
• Not enough filament is fed.

Troubleshooting / Solution
• Level the print bed.
• Clean the print bed with pure alcohol / spirits.
• Please wear suitable gloves to clean the print bed.
• Afterwards carefully examine the first print layer.
• Check the ambient conditions.
- The SIMPLEX 3D filament printer may not be ex-
posed to direct sunlight.
- Protect against drafts.
- Observe an ambient temperature of 15 - 32 ºC.
• At a room temperature of ≤ 21 °C, it is recommend-
ed that the print bed and nozzle are preheated
before printing begins in order to compensate for
differences in temperature between the room tem-
perature and the printer.
• Model must be aligned again to the zero position in
the CAD software.
• Ensure that the models are dropped correctly.
• When enlarging, a gap should not be visible be-
tween the model and the print bed. The model must
be placed flat and fitted on the virtual print bed.
• Tip: Use drop mode in Renfert mode.
• Clean the cogwheel of the extruder.
