My post right above yours pretty much sums it up.
Not enough top layers or the infill % is not high enough.
I agree - I have printed a LOT of PETG. I rarely use an infill percentage below 30% with 3 or 4 top layers. I've never had an issue.

Re: Support Separation from part not working as expected. Circular support generation is horrible.

I haven't seen any mention of Support Pillar Resolution. I suspect this is the issue with the circular model- that the OP is using the default of 4mm.

Try a support pillar resolution of 1mm on the circular part.

Model Position Offets -9999.00

Here's an issue I hadn't seen until 4.1.1 It only happens with some models. This one passed the repair checks so I think the model is clean. If I open the factory file in an older version they come up with the same offset, but I don't recall this happening when using those versions. Capture.JPG Fact...

Re: Twill Weave First Layer?

I think the results would be disappointing. It could actually be tested with a couple ziggity-zaggity models and two processes. There would be no differentiation between zones laying down in the same direction. In the carbon fiber image there is differentiation because of the curvature of the weave.

Re: [4.1.1] "Place Surface on Bed" broken

This is not how it used to work and is not the expected (or desired) behavior. I have 4.0, 4.01 and 4.1.1 on my machine and all three versions behave the same. I have a model with parallel surfaces and regardless of which surface I select it does not drop the model into the table - so while I can u...

Do that with your modeling software.

Re: Cull Prime Pillar for Dual Extrusion

I've never used the variable wizard, so I can't speak to that - but if you have two processes - one with and one without the prime pillar - go to the ADVANCED tab to set the start and stop heights for each process.

Re: Internal perimeter/ hollow core

I believe this is the same concept as you have proposed.

Re: Printing a threaded insert and accepting piece

There are a lot of overhang test prints out there which might be helpful in testing your setup. Here's my version of an overhang test - continuous from 40 to 80 degrees. For a standard thread you'll want to find a setup (layer thickness to width) that will be stable beyond 60 degrees. Also, make sur...
