when will we have something like this:
My flux actually did this to one of my prints a couple of months ago. I had supports on however the slicing software decided it didn't want to use them. It was a fun sight to see when it happened.
Bridging like that is (1) available on almost any printer and (2) hours to days of dialing in the temperature and other settings.
...for each spool of filament, because even something as putatively innocuous as the dye can affect the filament's bridging performance.
