Filament fails to unload after runout
When filament runs out on the MMU3 the print stops as it should and tries to unload, but the filament fails to reach the pulley wheel. It stops maybe 2mm short. So I have to disconnect the PTFE tube from the extruder and push the filament the last millimetre or so.. Seems like the FINDA sensor is placed too far from the pulley, or it simply is too slow to trigger when the filament runs out? In the pictures you can see the yellow filament as far back as it gets without manual help.
