Spool tangle inherent to Core One design?
I'm finding that my filament spools get tangled more often on my Core One than my Mk3. I think because the Bowden entry tube is stationary and so close to the spool on the Core One, that the filament, as it unwinds, gets overlapped, and if that happens, sometimes it gets stuck, and the Nextruder is not strong enough to pull it when it is overlapped and knotted. See image. I rarely see this happen on my Mk3 because it doesn't use a Bowden tube and the point of entry (extruder is much further away and also moving on X.)
Any thoughts?

I'm not a fan of the core one spool holder design but I've never seen a tangled spool unless you let the filament jump off the spool without securing the end.

RE:
It is physically impossible for a filament strand to get knotted unless one of the ends are free. Sort of like saying you can cut a rope and fuse it back together like magicians do.
If filament is knotted or looped under another loop, that happened before you inserted the free end into the printer.

Yes, you have to be very careful when using the spool for the first time or swapping it to make sure that the filament doesn't unwind prematurely, but this is difficult to prevent... I'm saying that the bed slingers are less prone to tangling because the spools are further away from the extruder...

I've had this happen on my MK4S feeding directly into the extruder. Mostly these were very cheap no-name PLA spools that were simply poorly wound and the filament would break or grind in the extruder gear. I've had some mild tangles on the C1 but not to the point where it was binding or breaking.

I had this happen for the first time today... and, frankly, I suspect the elegoo rapid petg roll was just messed up when they wound it.

I’ve had issues with nearly every roll of Elegoo Rapid PETG wedging in at the side about 3/4 into the roll. Horrible winding. But it’s such great filament and cheap.

Just had my first roll of Polymaker ASA totally tangled in my H2D HT unit. Misrolled from the factory. Haven't had that will the bazillion rolls of Prusament I've bought (though I've been buying less expensive stuff unless I need Ultramarine Prusament for my Orange Deleted Core One).
