    I don’t have issues with it stringing, but bed adhesion is a pain in the ass. Can’t get it to consistently adhere

    First rule of PETG-club is “dry your filament”, second rule of PETG-club is “dry your filament”… Thrid rule? Nope, it’s “store your filament dry”

    Jokes aside, other things you could look at:

    • nozzle, how worn is it?
    • calibration tests: did you do a temp tower? Calibration cube? Retraction test?
    • The vertical surface doesn’t necessarily have that appearance as a result of wet filament. In my experience, wet PETG will result in more random variations than that. It looks too regular IMHO, is everything that should be tightened actually tightened?
    • have you calibrated the extruder steps?

      I would bet on retraction here. Dial that in and 90% of the stringing goes away.

        Using G10 can recommend if you scratch it up you can just use the other side and if you have a metal probe you can add aluminium tape to the side you aren’t using and get full functionality.

        Or just use a textured PEI plate at the proper bed temperature. There is very little need for special adjuncts to print PETG.

    @mooklepticon I print almost exclusively with PETG and what I have found that works for me is to dry the filament, even if coming right out of the package. With some filaments, decreasing the nozzle temperature also helps.

      260°C nozzle on the bed 225°C nozzle afterwards

      Wow, that’s a huge difference between 1st layer and later! I’ve never seen that big a delta.

        @mooklepticon
        I think my Z-offset is too high and I’m compensating it with temperature, but I don’t care - nozzle cleans itself well, prints well and even structure is good.

        When it works, don’t touch it 😀
