A mistake is always an unfortunate sequence. With Bambulab you can go fast, a little sand in the Formula One car and you drag it all over the race track. So you have to get one parameter better - then the final total will be balanced.
May and since it`s PETG:
-
Do a first layer print at 50mm/s - Then you rule out a lot and already show in which direction you have to move.
-
Cleaned the black texture plates very thoroughly (Isopropanol).
-
Pay attention to which side of which textured plate you used. May all sides are aleady gone. Maybe it’s just one small zone how is gone and once there’s dirt on the nozzle, then the adhesion in the good zones is also gone. And this is no longer compensated for over the next layers, you just move on from layer to layer. Not like the old slow printers, where the error was simply overprinted by the next layer…
-
I printed the first layer a little deeper so that it pressed more into the plate…
-
Cleaned all dirt after every print, even under the silicone sock. A lot of dirt can build up there and then a lot builds up very quickly.
-
Z-hopping + layer height below 0.45 can become very critical at high traversing speeds (moving to the new printing position without printing). The Nosel can not melts the strings in the Z axis fast enough out of the way when driving over, this can lead to a lot of microcollisions, which in total can lead to the tearing off of the first layer - and that only has to happen once and then the dirt is back on the nozzle and the adhesion of the first layer is gone.
-
But the last thing on my mind is wet filament. I should see it blow bubbels but i can`t. In your case I see pathrise and no liability of the first layer.
-
Incorrect route energy (sum of heat quantity, time and travel speed)
But even I can be wrong sometimes… I have black texture plates in the trash, I only have the gold ones, 5% Less of these problems
