MMU2S filament loading after IR sensor trigger
I have problem when changing/loading filament from MMU2S to Extruder. MMU2S work OK, IR sensor also work OK.
Problem happen when MMU2S loadfilament and IR sensor trigger to 1.
MMU2S extruder stop. Main Extruder stop for a while and then load filament about 2 rounds.
This is OK.
But then extruder go back about 2 rounds and then filament sometimes go back too much, go off from bondtech and IR sensor go back to 0 and MMU2S take another unload/load procedure.
I think that IR filament sensor should go active not when touch bondtech but 2 - 3 milimeters after.
Alternative extruder movement forward/backward should be different (2 round forward, 1.5 round backward ).
Anyone have similar problems.
Re: MMU2S filament loading after IR sensor trigger
If this is with firmware 3.0.0, there the theory is as follows:
MMU loads to Bondtech and triggers IR sensor
Bondtech loads 50mm of filament
Bondtech unloads 45 mm of filament
IR sensor is checked again and if not "1" then unloads and retries
This, apparently, is an attempt to stop missing layers by ensuring that the filament is properly loaded in the Bondtech.
Unfortunately, it just doesn't work for me (lots of failed loads), so I have reverted to 3.6.0.
