become weak. In the NewCreatorK setting, set the brimline to be larger than the
default setting of 20 so that the initial 10 lines can be used to check the line spacing.
-
If the lines do not stick together after adjusting the Thermal Offset, reduce the width
of the first layer line in 2-5% increments in the slicer settings.
2.3
When the lines making up the first layer are apart in select, fragmented areas of the print
-
The "Thermal Expansion Bed Calibration" value can be used to re-calibrate the bed if it
is tilted uneven. Set the correction value to raise or lower the bed plate at each of the
four corners in the range of 0.005 to 0.01 mm as you stand in front of the AEP front
door and look down on the bed. However, the sum of the two diagonal vertices must
be set equal.
-
Narrow the gap between the bed and the nozzle by adjusting the knobs close to the
problematic areas of the first layer.
2.4
Filament agglomerates outside the nozzle, scratching over the print on the bed.
-
The front door lock is unlocked during printing of the first layer (in AEP 450), so during
the first layer printing, open the door and remove filament ooze at the nozzle end. If the
filament ooze at the nozzle end comes off as the print is peeled off the bed, use the
Hera to clean the outside of the printing nozzle before re-printing.
2.5
Despite the successful printing of the first layer, the print falls off in later stages.
-
At the bottom of the print object, create and attach a “Cylinder”-shaped sample object at
a thickness 1.2 times greater than the layer thickness (like a brim) so that any angled part
of the print object disappears.
-
Any part on the first layer that has a black shadow is indicative of low layer adhesion to
the bed plate. Use the Thermal Expansion Bed Calibration to strengthen adhesion. (The
newly set value will be reflected in the next print result.)
2.6
Angled parts of the print fall of the bed
-
Angled parts have a greater stress that can lead the print to fall off the bed. Create and
attach a “Cylinder”-shaped sample object at a thickness 1-2 times greater than the layer
thickness (like a brim) so that any angled part of the print object disappears.
2.7
When a PEEK part swells and the print falls off
-
If the object file is of a shape that accumulates the bed heat, it is necessary to lower the
overall printing temperature. Lower the extruder temperature at an increment of 5
°
C until
