Filament not loading on Core One
I just finished building the Core One MK4S/Kit. There were a few hiccups but I finally made it through all the test! I was so excited until it would not load filament. It looks like the gear that filament first enters not moving/feeding. Any ideas?

RE: Filament not loading on Core One
Check a few things:
If the gears have that thin washer behind them, make sure you replaced it.
Make sure that the tube is over the long grub screw at the bottom of the idler arm.
Make sure you didn't get any lube on the gears. Pull them and clean them with IPA, add lube sparingly and put them back and make sure they turn before assembling everything.
Check ther idler sping/screw tensions.
I have done most of this wrong!
