Was just wondering if anyone had some tips for printing PETG on a direct drive.
I see you have recently installed a Microswiss Direct drive on your printer,
If you have a profile for PLA already tuned and printing well for the direct drive extruder, I would use that to build your PETg profile. That is the route I took when I was building my PETg profiles for different brands and found that very little settings got changed compared to PLA.
To start, temperatures need to be raised, I print at 240c hotend and 70c bed for most PETg brands.
Retraction can vary depending on brand, but with the Microswiss I like to keep it between 1mm and 2mm, Microswiss recommends 1.5mm at 35mm/s retraction speed.
Part cooling fan on at 35% max after layer 2
That is my starting point before tuning for flow and speed using xyz cubes or other tuning prints.
Hope this helps!
