I’ve been having some serious issues getting PETG to print well, and I was wondering what settings other are using with success? I’m using a bedslinger in an enclosure and normally i print PLA with 200mm/s.

What are you doing for nozzle/bed temp, cooling fan, printing speeds etc? enclosed/open?

What is your printer capabilities normally for e.g. PLA?

    So, I can’t print PETG in a cold room without extra effort.
    I also can’t print it on smooth build plates very well.
    And I can’t print it very fast or with surface layers that are super complex.

    PETG needs a good surface that it’s close to and can adhere to and it needs to be warm.

    I set my build plate to 50°C for at least an hour before printing and leave a fan running in the enclosure to spread the heat around. Bed is set to 70 and I only use the textured build plate and make sure the nozzle is clean before it prints cause if it starts sticking elsewhere it won’t stop.

    Oh and if I open the enclosure part way through the print and cold air hits it I find I usually lose the print.
