Your not getting layer adhesion, that much is obvious. The cause is what’s in question.
If I had a dollar for every time someone came in and said “But I cleaned my plate thoroughly”…
It could be that your plate suffered some contamination from the filament you said wasn’t performing. Did you use very hot water and soap? IPA is not enough. Did you scrub it with a nylon scrub pad?
Use this:
Or this:
But definitely NOT this, because it will mar the PEI coating
The second option is to increase the bed temp in the filament profile. This will help but could introduce elephants foot compression at the bottom of the model.
And last but not least. Brims can cover a multitude of sin if one doesn’t have a perfectly clean plate or if the filament is just being troublesome.
