Is it possible for the leftover residue, of tape on a spool to be scraped into the feed? As the filament drags over the edges of the spool?
Heads up btw, I’ve found that a good way to remove sticker residue on comic book bags/boards is to take the peeled sticker and use it to “blot” up the residue. It’s possible that may work for you with the filament. Idk about your actual question though, seems like it’d be possible.
I’m not really concerned about my former issue. I hadn’t yet touched the calibration settings of my printer. They made a significant difference. I got a completely different issue now which I’m certain is the big one that nobody has a set answer for.
