Thats history, I did a factoy reset, with a new nozzle, reset cura to defaults except extra walls, and successfuuly built my busted math version I just posted about. > The bed temp and extrude temp seem high.

With BuildTak on the glass, I expect 65C/232C to work. And be easier to remove. Print cooling on the dremel is extremely well done, and while I have that fan started at layer 2 and 40% they recommend only 30%. We'll see. I'll likely have to adjust something as I doubt the build underway now will be final. And finally, something it sticks to, buildtak sheet. Sticks really well at 80/250 so the next build will try 70/240. The 80/250 build was a mite bumpy. But cleaned up and full of bb's to only about 1.5" of empty space as I used a .02mm small spec for the bearing track bb size, which is too much preload, so this build underway is building with the exact measurement. But I fully expect to have to fine tune yet another copy after this one, probably the ID so it fits the drives spline rings more exactly, and an adjustment of the dummy bb size to get a best fit. > Is it possible that the filament is damp?

So I now have one nearly empty spool of this odd size, and this one to use up yet. If I build a third, the nearly empty spool will get finished. The dremel claims it will pause and wait if it runs out mid build. I've no clue how it does that but the upper guide feeding the head mounted ejector, has a 3 conductor cable coming out of the bottom of its plastic molding. And I've most of a roll of green PETG left on the ender that I'll probably put in the oven for a few hours before I rewind it on a dremel spool.
