Filament refusing to feed.

[EagleSeven]

Situation - using the Utilities/Change Filament/Load Right Menu and waiting until the correct temperature - as I start pushing the filament in it appears to start feeding and then it just "skips" this is accompanied by a rapid tick, tick, tick noise and the filament won't progress any further.
I've tried on the second head and it does the same.
The printer has had about 20 hours use.

As others have said,
the guide-tubes (throat) may be full of un-melted filament.
I've had to use a drill-bit and/or a brass-rod
to clean out filament that broke close to top of tube,
since it would not melt enough to be able to push it thru with new filament and was stuck.

First try pushing in a brass-rod with pliers, before disassemble though,
you can apply more force with hand than motor-drive can.
May be able to push it down enough to start melting.

Note: brass-rod should be just large enough to fit in guide-tube without sticking,
use only brass-rod so it will not damage drive-gear on motor
