Question / Error / Problem Cause Troubleshooting / Solution
Unit displays a lament ow
error.
Either too little lament or
no lament at all is extruded
from the nozzle.
• Nozzle temperature is too low. The
lament does not melt and cannot
be extruded from the nozzle.
• When using TEMP1 and TEMP2
group laments, always load / un-
load the lament with the TEMP2
setting.
• Only use the temperature specied for the lament.
Relevant information is provided on the spool and
on the packaging of the lament.
• Objects printed using SIMPLEX aligner model
Filament must be sliced using the "SIMPLEX
aligner model" prole.
Nozzle is blocked • If the temperature of the nozzle is
too high, the lament can vitrify on
the inside wall of the nozzle and
harden.
The ow of material may gradually
come to a stop and the nozzle may
become blocked.
• Ensure that the temperature for the
lament is used for printing:
- TEMP1: SIMPLEX study model /
working model / multi-use
- TEMP2: SIMPLEX aligner model
• Step 1:
- Heat the nozzle to 255°.
- Select the EXTRUDER menu. Wait until the ex-
truder has reached the required temperature.
- Press the "Load lament" button. This automati-
cally results in extrusion of 15 cm of lament.
- Perform this action three times.
- Now select the nozzle temperature required for
the lament used. Wait until it is reached.
- Press the "Load lament" button and check wheth-
er the blockage has been resolved.
• If step 1 is not successful, replace the nozzle.
Nozzle is blocked • If the lament is transported via the
extruder into the hotend and then
through the nozzle and dust and dirt
also accumulate, there is also a risk
of a blockage.
• Store the lament in a dry location
away from dust.
• Step 1:
- Heat the nozzle to 255°.
- Select the EXTRUDER menu. Wait until the ex-
truder has reached the required temperature.
- Press the "Load lament" button. This automatical-
ly results in extrusion of 15 cm of lament.
- Perform this action three times.
- Now select the nozzle temperature required for the
lament used. Wait until it is reached.
- Press the "Load lament" button and check wheth-
er the blockage has been resolved.
• If step 1 is not successful, replace the nozzle.
How long is the average ser-
vice life of the nozzle?
• The service life depends on the lament used.
- As it contains plaster, SIMPLEX multi-use lament
causes greater wear of the nozzle.
SIMPLEX multi-use lament approx. 400 operating
hours.
- SIMPLEX study model, SIMPLEX working model,
SIMPLEX aligner model approx. 800 operating
hours.
How should the outside of the
nozzle be cleaned?
• The outside of the nozzle can be cleaned using a
thick, temperature-resistant cotton cloth.
• Do not use alcohol, pins, drills, or sharp-edged
tools! Caution: Danger of burns!
• The dark color of the nozzle is a normal reaction
due to the temperature of up to 250 °C.
Filament is extruded between
the nozzle and the hotend.
• The nozzle is not screwed on se-
curely.
• The nozzle must be screwed on securely to the
hotend.
The nozzle has become
blocked after replacing SIM-
PLEX study model lament
with SIMPLEX aligner model
lament or vice-versa.
• The temperature at which the la-
ment was replaced was too low.
• TEMP2 must always be selected when replacing
the lament. This is the only way to ensure that the
previous lament is completely removed from the
nozzle.
Print object does not adhere
to the print bed.
• The distance between the nozzle
and the print bed is too large.
• Level the print bed.
• Kapton lm of the print bed is dirty. • Thoroughly clean the Kapton lm with alcohol.
• The Kapton lm may need to be replaced.
