New Extruder manual feed.

I just upgraded to the new extruder with the ball bearing but now I cant manually push through filament. I used to be able to do that with the old one before i started a print. Any tips?

Maybe I don't understand the issue, but when I turn the big wheel by hand, my filament is pushed through the hot end.

Turning 30cm by hand is hard, but I found a sollution. I undoo the leaver screw- lift the leaver up and swing down the ball bearing part.

Which is the normal way, if you could push it trough by hand before, then it wasn't putting enough pressure on the filament.

Before it was so that I rotated the leaver and there was less pressure.

Now, rotating the leaver makes no difference. I have to displace the leaver vertically.

The new spring design will have some pressure on the filament which will likely require you to either disable the steppers and rotate the gear wheel or lift the lever up to relieve enough pressure to simply push it through by hand.

Personally, I'd love to see a little handle attached to that small hole in the wooden gear. Then, we could turn the gear quickly using that handle to put new filament through the bowden quickly.

Why would you want to crank a new filament in instead of just opening up the extruder and pushing it through by hand? That's much quicker.

In my case, it's fear, I guess. It took me forever to get my extruder working reliably, so I'm afraid to open it up.

Do you have the old one or the one designed by Bertho? If you have the old design I would highly recommend either printing and assembling the one linked on Thingiverse or buying one from Ultimaker. It's a great upgrade, it's set and forget. It made retraction work much better for me, no more stripping since I installed it.

I have the new one.
