Horrible Layer Adhesion, but only sometimes

I’m having some issues with layer adhesion using PET-CF (PET, not PETG). The issue I’m having is sometimes my prints are strong, and then I’ll re-run the exact same print file immediately after and then it prints with horrible layer adhesion. It essential crumbles in my hand. I am having this issue with both my X1’s. I have tried multiple different rolls of PET-CF and same issue. Sometimes it prints perfectly, and other times it’ll print with horrible adhesion.

I have even bumped up the nozzle temp and lowered the parts cooling fan. But the

Any idea what to do? I have tried drying the filament as well, although I don’t believe this is even an issue since the print’s surface texture is perfect, it’s only the layer adhesion that is having issues.

I actually came here for a similar issue… waiting to be able to create my own topic lol. Did you create this in fusion 360?
