Pict. 34 - LCD notification: printer is paused because of an unsuccessful filament load
Cause
Solution
Filament is blocked somewhere between
the MMU2S unit and the spool.
Check, that the filament can move freely
and can be loaded to the unit.
Resume
print*
.
PTFE tube is clogged - in most cases, it’s
because of filament strings or filament ball
ends. To learn how to prevent this situation,
see the chapter
13.8 Different filament tip
shapes after the unload
.
Unscrew the Festo fitting on the MMU2S
unit and also on the extruder side. The
filament string will probably stick out of
MMU2S unit. Make sure, that the filament
can go freely through the tube and that the
tube is clean inside. Pull approximately 20
cm of filament out of the unit and cut this
end - the gears have most likely damaged
this part of the string, so it’s better to
remove it. Mount everything back and
resume print*
.
IR sensor is not working properly or the
sensor cable is broken / damaged.
Perform the calibration of the IR filament
sensor. See chapter
6.1 IR filament sensor
calibration
Check that the sensor is working properly.
Open LCD menu - Support - Sensor state
and you will see the IR value. If the filament
is not loaded, you should see value “0”.
Otherwise, when the filament is loaded, you
should see value “1”.
*How to resume print after repair?
Option 1:
Select on
LCD menu - Resume print
. The printer will automatically preheat the nozzle, try
to load filament and if it’s successful, it will continue printing.
Option 2:
Press the middle button on MMU2S unit. The unit will repeat the last unsuccessful operation.
