Hi folks.

I am trying to print some face shields for the NHS or indeed any health body that needs them, using PETG, but am struggling to get decent prints, they print fine with PLA, but as I haven't used PETG before I'm trying to set up a profile for it.

Does anyone have a PETG profile to run  on an Anycubic i3 Mega please?

Cheers.

I've been doing the same (face shields, first time PETG), and had the same problems (although I'm using vanilla UM3 print heads). For me, the problem seems to have been the retraction settings -- once I found this post, below from IwanBeentjes and used those retraction settings, the prints started doing MUCH better (although still a decent amount of stringing, which seems inevitable with PETG).

 

I dropped my print temp down to 240, which improved things further, but I think this depends on the specific spool of PETG you have.
