Kobra X suddenly stops extruding between layers with both 0.25 and 0.4 mm nozzles
Hi everyone,
I’m having a strange issue with my Anycubic Kobra X. The print starts normally and the first layers look fine, but suddenly the next layer does not bond properly. It leaves a large gap between layers and creates a lot of loose filament/stringing, as shown in the photos.
I have already unclogged and cleaned the nozzle, but the problem continues. It happens with both the original 0.4 mm nozzle and the 0.25 mm nozzle, so it does not seem to be caused by one specific nozzle.
It looks like the printer temporarily stops extruding enough filament while the printhead continues moving. After that, it may start extruding again.
Has anyone experienced something similar on the Kobra X? Could this be caused by the extruder, the 4-in-1 filament combiner, the PTFE tubes, the ACE system, or the Z-axis?
Any suggestions for tests or fixes would be greatly appreciated. Thanks!
