PETg Advice?
After getting PLA working pretty reliable, I tried some PETg and I keep ... I dunno. Failing.
It seems like the stuff is slipping in the MMU? It's not grinding, I just get missed loads and unloads. Does anyone turn up the distance, tighten the screws, etc with PET versus PLA?
I maintain an informal list of San Diego, CA 3D printing enthusiasts. PM me for details. If you include a contact email and I can add you to the informal mailing list.
Re: PETg Advice?
What do your tips look like? Any possibility of strings of filament or other debris blocking the finda?
That tended to be my problem with load/unload issues, and at least in my experience I'd be concerned with stringing on the PETG. Dialing the temp (as low as possible is my guess, possibly slowing down your print speed to allow it) would be a good start.
