Maker Gear M2, extruder clogging

[Dexenthes]

I'm having the exact issue right now. How do you take apart the gear box to analyze the problem?

Who said anything about a gearbox?
When did your clogging issue start? Not feeding can be as simple as a tangle in the filament, or the gear needing cleaning.

I'd guess about 7 times out of 10, the issue has to do with too much tension on the filament drive screw, and the other 3 times, the bed is too close to the nozzle for the first layer. (like in the video ) Or both.

Read through these two threads for hints on how to fix the tension problem and check the extruder gear area:

or the filament get at a weird angle with the filament guide and it get stuck and even if the tension is correct it can't pull it

it happened to me this is why i am printing a new filament drive http://www.thingiverse.com/thing:984369

but there are even less sophisticated one

better then the original one that is quite short and if u use a 1kg filament it may get stuck sometimes
