Core 1: severe underextrusion?
Moin!
Over the last days I upgraded my MK4S to a Core 1 and added the camera, filtration and MMU3.
The printer produced one normal looking nice first layer, than it stopped extruding correctly. During printing there are clanging noises which - I believe- come from the extruder.
No failure messages at all, all calibrations passed, MMU3 seems to do its thing.
What should I do next? I pushed the hotend up as far as I could, I did several recalibrations of the extruder gears, I tightened the extruder idler screws a little bit...
This is the wrecked beginning of a benchy:

It's possible the idler tension screws are too loose. Try tightening both 1/8 of turn each. Sounds like the filament is slipping on the extruder gear.

yeah, the standard setup for the extruder screws used for the mk4 series still apply! I recommend checking the full build instructions and check if you can spot any major differences in the way the extruder is setup...
