    That was my theory because of the damaged hexagons on your original print. Something was causing the plastic from the previous layer to be too high and the nozzle hit it while travelling.

    You could also play with your travel settings. Combing may be undesirable on this type of print.

    Maybe curling can be reduced by drying your filament, but I haven’t tried that. Curling seems to happen when the plastic stays molten for too long, often because it is going down too hot or because the nozzle is coming back around for the next layer before the previous layer has cooled enough.


  • It looks to me that more is going on here than just how dry the filament is. I see a lot of deformity on the underside of overhang structures which makes me think that the temp is actually too high for the speed that your printing at. I would guess as the plastic went down it was curling edges upwards into the height of the next layer and eventually the nozzle hit this plastic that was too high causing some damage. What speed are you printing at ? Petg likes to print real slow in my experience. Like 20mm/s or less gives it more time to cool. I go as slow as 5-10mm/s when I’m using a large nozzle, but with a .04 you can go faster. Lowering the nozzle temp will reduce the puddling and curling up effect.

    I don’t dry filaments because I don’t care that much about things being perfect. If my plastic is going down goopy, I just turn down the nozzle temp until it isn’t… I’ve come to accept that things often print better if I set the print speeds to be slow. It gives the layers more time to cool before the nozzle comes back around.


  • I think because people no longer trust you because you confidently said that something does something, and then when questioned, you said that you don’t really know much about it.

    It gives your comments a low trustability factor. People will think that anything else you have to say on the matter could be misleading.
