That shouldnt really be happening, even if the filament is drooping to the side, the stepper should still pull the filament.

It could be the position of the filament feeder, the black block.

Whilst taking mine apart to level teh nozzles etc, I found that once I couldnt not feed the filament though as easily as before I took it apart.

So what I did was remove the fans and heatsink, loosen the screws on the blocks and then all a little force to push the block to one side before tightening the screws again.

At one side I could not feed the filament at all with my hand, of the other side it went through very easily.

So I think your block has be tightened too far to the loose side, so do the above but make sure you move the block to the right side.



I've not added or tested these yet either, so if the above doesnt help these should hopefully
