Multi-material setups like Mosaic's Palette and Prusa's MMU manage filament tension. We probably don't see it on most consumer/hobbyist p...
Makes sense, but a simple, adjustable friction tensioner seems like it would be an ideal fix to prevent this sort of issue.
If the concern is that the machines don't have the oomph to pull material with it under tension, I'd honestly just find an old feeder assembly off a welder and Frankenstein it to spool out material when the print head is running.
I mean all the parts are already there, including a trigger for sending signal to start and stop. I'd suspect that something like that would also help reduce breakage since you can better control friction on the filament.
To be fair, I don't do much with 3d printers, I just saw the problem and my brain jumped to something I was pretty sure might be a reasonable solution and scalable/cheap.
