I print PETG on buildtak. First layer is definitely "smushed". If I'm worried about adhesion, I'll throw some magigoo on the buildtak. I print push plastic PETG (10KG rolls) at 255c and 90c bed. I back down the bed temp to 80 after the 3rd layer and turn the fan on. I was getting too much sagging wi...

Not sure on why you can't remove it. That's a metal collar if yours is like mine. Is it possible that the threads are galled and stuck in the collar? Can you clamp the Z and twist the know?

Would you mind sharing your Config and Config_adv files? I'd like to give the upgrade a try.

Thanks for that. I spoke with support yesterday. There is apparently a daughter board in the mix that is not available as an upgrade. I'm assuming its a level converter to change from 5v to 3.3v for TX/RX pins. Not sure how the 5v power is being tapped to power the PI. It appears to be powered from ...

Thanks for the great information. In addition to being a 3D printing enthusiast (I own a Makergear M3 ID), I'm a physician in practice at a 1000 bed hospital with multiple patients currently admitted for COVID-19. We have an acute shortage of masks (surgical masks, N95 masks, and related PPE equipm...

Reddit says its bogus. https://www.reddit.com/r/3Dprinting/comments/fke0oz/coronavirus_3d_printing_megathread/ I'm working with a Houston Hackerspace to print visors. They're crowd sourcing (sewing?) masks with community support that I'm assuming is like the FU Mask. They're also working on a PAPR r...

Which version of Simplify 3D are you using? I had a problem with stringing on 4 and problems went away when I reverted to 3.
