TPU / flexible filament - no option in Prusa Slicer for MMU3
So whats the secret? How do I print with TPU with the MMU3 installed (Mk4)?
You bypass the MMU, feed TPU direct and use the regular Mk4 profile.

That is exactly how I am doing it as well. I have turned off the MMU in the settings menu and then just fed the TPU directly into the extruder.
and use the regular Mk4 profile.
- not the Mk4+MMU profile.

Thanks for this.
So I disable the MMU via the settings screen option in the Mk4.
Do I also need to make any settings changes for the filament sensor if I am bypassing the MMU3?
No
For very soft filaments you may need to lower the Nextruder idler pressure.

From my reading of the manual on single color/filament printing, you should not need to turn off the MMU. Just slice to whatever regular profile you want and then select the filament you want from the user interface on the printer. It has worked for me.
