Bypassing the MMU3 for Flexible filament
Hello everyone!
I recently setup the MMU3 on my MK4S and got everything running. I was wanting to try printing with TPU/TPE, and I heard that it doesn't play well when fed through it.
If I wanted to print using TPU/TPE/other filament not supported by the MMU, how would I tell the printer to ignore it? Would I just turn it off in the Menu? If I do, are the settings for it (loaded filament, filament sensor calibration, etc.) still saved on the printer or would I need to redo all of it?
RE: Bypassing the MMU3 for Flexible filament
When I want to print TPU I just disable the MMU on the printer. Then I disconnect the bowdentube from the printerhead and uses the printer just as before I had MMU3. This worked fine with both MK4S and Core one.
RE:
@inge-h-2 -- have you tried a PTFE Y-splitter to allow filament input to the Nextruder to originate from either the MMU3 or Core One side spool? Any concerns post MMU3 modified Nextruder filament sensor bypassing MMU3 as filament source?
I've read that prior to the MMU3 upgrade, the Nextruder filament sensor detects presence at the entrance of the Nextruder vs. with the MMU3 modified filament sensor it detects filament presence when it begins to engage the Nextruder gears.
I hoped to put in a PTFE Y-splitter above the Nextruder to it can receive filament input from either the MMU3 or the Core One side. I am searching for a good PTFE Y-splitter that will maintain low-friction filament movement for loading/unloading from either input. Would appreciate any info/advice if someone has performed this on Core One + MMU3.
