Printer not accepting filament
I was doing a print that required multiple filament changes, which I have done before with no problem. The filament was ejected, I went to insert the new color, and it won't feed in. I can see that the filament gear is turning to accept the filament, but it won't go into the hot end. It's almost like it's blocked. I've heated the hot end and inserted a needle in case there is some blockage but no matter what I have tried, the filament won't feed into the hotend.
Any ideas on how to fix this? I can't do a cold pull because I can't even get the filament into the hot end to do one so I'm at a loss as to how to get it working again.

RE: Printer not accepting filament
Yep...I do believe this was this issue. Took a while for me to get the hot end out in order to pull the tube but based on what you see here, I suspect this is what was causing the block.
Thanks for the help! Was beginning to think I wasn't going to be able to print ever again.
RE: Printer not accepting filament
I can confirm that after changing the tube the printer is once again accepting filament. Just recalibrated and everything seems good to go.
Much appreciated!!!
