MK4S MMU3 Overature PETG settings help?  

RE: MK4S MMU3 Overature PETG settings help?

It doesn't look like the settings file was added. Weird, I put it in the "Attach file" part. Anyway, here are the settings I used for the MK4 that used to work:

RE: MK4S MMU3 Overature PETG settings help?

Just use the prusament PETG profile.  It's worked good for me with many different PETG filaments. 

RE: MK4S MMU3 Overature PETG settings help?

It runs way too hot, unfortunately. I've tried adjusting it to work with Overature, but wound up just modifying the "Generic PETG" profile for the MK4. After many tries with the MK4S + MMU3, I can't get it to play nicely.

This is the most "successful" print yet.
