The cartridge of PLA in my Makerbot Mini seems to catch on something and be prohibited from turning. Obviously, when this happens I get an "air print." If I roll the cartridge by hand there is a click. My fix is to roll it a bunch of times so that the PLA can be pulled without the cartridge having to turn. This is obviously not a solution. This happens with whatever cartridge I use. Anybody seen this? Anybody have a fix?
Thanks for any insight.
Cheers, Scott
