Knocking hotend off track
We make multi day prints , of large models and experience that the hotend is knocked over by the nozzle. That obviously causes failure.
This does not occur when printing smaller models, such as benchy.
The picture shows the state of things just prior to a "hit", you can see that blob just waiting ....
These blobs comes from buildup on the nozzle that is deposited. This does not look like a constant buildup, but something that occurs with some time in between.
In general the extrusion looks good on extrusion tests.
Filament : PETG
Hotend: Rapido UHF, 0.6 mm nozzle
Temp: 235
Slicer: Orcaslicer
Flow ratio : 0.9 , and checked with flow calibration to be a little on the low side.
Pressure advance 0.06
