12.6 Filament not extruded during the print (missing layers)
If the extruder keeps moving across the heatbed (following the instructions from a G-code),
but the filament is not extruded at all.
Solution 1:
​
The hotend in the extruder might be jammed, please head to the MK3S 3D
Printing Handbook - chapter ​ ​ 13.4 Clogged / jammed extruder
Solution 2:
​
Filament IR sensor triggered (IR value is “1”), but the filament didn't reach
Bondtech gears. It happens if the filament sensor is not calibrated properly. Please calibrate
filament sensor as described in section
​
7.1 IR filament sensor calibration

13.7 Filament cannot go through the selector
Selector jam may be caused by:
1. The hole inside the selector is blocked by filament tips or strings.
Solution:
a) Move the selector with the right button on the MMU2S unit to far right (service
position).
b) Unscrew the Festo fitting from the MMU2S unit.
c) Use a 1.5mm Allen key to push the jammed pieces of the filament out of the
selector.
d) Clean the hole with compressed air and try inserting the filament again.
