Extruder spring metal cap

[user_2308201407]

Ok i had a problem with extruder jamming up. I took it apart and the spring shot out. I found the spring and rebuilt it, no extrusion . After 2 days I discover there should be a metal cap also . I’ve ordered a new extruder kit but was wondering if anyone has the dimensions of the cap so i can print one until the kit arrives, thanks Dean

That’s a really stiff spring, and the screw that compresses it is pretty small - you’re not gonna print something that won’t just immediately fail.

Find the right cap, or rig up an equivalent with washers.

I’m thinking a ASA part with a washer on top , until i get the kit, do you know the dimensions

[user_2308201407]

I printed one in ASA, and it’s printing fine. I swept the floor and found the metal cap, JEEZ its small. Why dont bambu offer schematics drawings of each part , if i had known there was a spring in there i would have done things differently

This is the ASA one, im going to keep using until it fails

You could have ordered the P1/X1 screw kit, it has 5 of those caps in the kit, bambu calls it pressing plate

Screws Kit - X1 Series/P1 Series and AMS

and it has 5 springs as well

17. The pressing plate & spring for the extruder gear assembly

The complete kit:

Screws kit - X1 & P1 Series and AMS

Thanks but how would i have found that while looking for P2S parts

[philch]

Oh sh… no you could not because I did not notice it was a P2S, I just read P series in the category… Now I don’t know if the cap is the same P1/P2, I think it is but can’t be 100% sure… sorry

FWIW, here are the dimensions of the spring and cap from my P1S screw kit. You can check if they’re the same

[user_2308201407]

Thanks for that , but this one is even smaller, diameter is 5.6mm, and spring only 7mm long

[philch]

OK spring is shorter but cap is also 5.6mm in diameter
