Nightmare start

Thanks for the help.. The extruder in your pic there is the same as the one I bought.
The brass gear though is different to the one that came with my printer.
I have three here.. I've just put back in the one that came with the printer (the silver coloured one - I cleaned it up of course)


Could the state of the original gear hold the clue to what's happening?


I've tried two different gears and the slightly bigger/sharper one clicks more often. The original one waits a 30 seconds or so and then clicks.

The original gear pictured Definitely Needed Cleaning !
The gear size and type must Match the design of the extruder and the Pulley in it.
The brass gear pictured has larger and Fewer teeth than the brass gears that came with ours
but I don't know if that makes much difference or not.
I think More teeth would help though.

The brass gear appears to have slightly larger outside diameter ?
If so, then I doubt the original gear would fit the new spring type extruder ?

Does the Gear Hit the Pulley ?
They should not touch each other when filament is going thru,
but should fit tightly together when No filament is between them.

It's about 0.2mm bigger in diameter. The spring extruders didn't actually come with gears.. The brass ones I have came with two other spring extruders which didn't fit.

I've taken the nozzle off again now and cleaned the nozzle out with a small drill bit.. A quick test on the filament load program for 30 seconds hasn't clicked yet but I will try again tomorrow to see how it is.. a little late for 3d printer noise here unfortunately..

EDIT: It fits tightly when no filament yes.. however I didn't check to see what it was like when filament was loaded.. I had put the fan back on by then.. Can do tomorrow..
