To pull this thread from oblivion again … I just ran into the same calibration issue #123.
Toolhead info says it has done 492 hours - but this is my second one on this Flux Delta.
First, I looked for obstacles, but there were none. Had a new nozzle mounted, then painfully removed the BuildTak Layer from the metal plate because it had small pits burned into where the nozzle always touches during calibration. No luck. UH-OH #123.
Is the pressure sensor under the left front rubber pad gone mad eventually? How to replace it?
Since this is used during the “change filament” process to speed up extrusion I know that it is still working, but maybe it is now too sensitive: filament runs through faster than before.
