MMU2 - PETG success

Hello,

After fighting with PETG on MMU2, I've finally found settings which are working for me even at 255C.

First of all the default settings are producing bad filament tip. Causing a lot of issues during printing. This is how they looked like:

After trying many things, I came up with the following settings:

This is the result:

Hard to believe that changing only couple settings in Slic3r makes a difference between success and failure. The gecko was printed over night without any issues. Everything comes down to a nice filament tip.

Thank you for the setup information on PET. What extruder temperature did you end up using and which filament?

250C and 255C work both the same. The layer bonding is very strong at this temperature, even better than PLA. That's why I don't like the Prusa approach going 230C for PETG.
I'm currently using only MakerGeeks PETG and translucent is very stringy. So please don't take this success as recommendation for MakerGeeks PETG. Try the settings and adjust it to your filament.

Here is the gcode, if someone want to try it (Input 2 and 5)
