My name is Karl I'm 76 Married 56 years and Love my 3d printers i Have a k2 plus and a k2 Pro Retired

I have a k2 plus working great but my new k2 pro leaves a long tail on the filament waste witch gets stuck in the waste shout and wastes a lot of filament any help is greatly thankfull

Hear is a Pitcher of the tails I'm talking about

I'm a noob, but I think that is perfectly normal when it is changing filaments, particularly if you have a multi color spool. It extrudes the excess old color filament when switching to purge it.
