Description

Made in response to Koen Burkink's post / founding of the possible cause for Slot 3 (and possibly 2) PTFE tube not a straight enough feed to the filament hub inside the AMS and causing failure in pulling the filament out.

So he drilled a couple of holes and uses zip ties to secure the PTFE tubes.

So I made a quick design in Fusion 360, a small guide with small opening to insert this guide on the tab… the pfte guide is angled a little towards the filament guide…

You should install the PFTE tube first to the Hub, then slide it into the guide. When the whole thing is put back together, the PTFE shouldn't be able to slide out from the guide since it is pressed against the bottom of the AMS.

Include the 3MF from BambuStudio and the Step file,

Any issue please let me know

For ALL that have these F&%*'n problems... along with this cool PTFE Guide, up the PTFE Tubing I.D. to 3.0 mm. I replaced every section of PTFE tubing I have to 3mm I.D. x 4mm O.D. Helps tremendously!

Where can i find 3.mm I.D x 4mm O.D PTFE tubing?

@papsjundi

Thank you! which PTFE parts you replaced? just inside the AMS? or all the way to the HUB behind the printer?

@JAnderson

I replaced every tube on the machine except the AMS. When I get a jam in the AMS, you can be sure I’ll replace everything internally as well.

@DMTaino

Did it help?

@bollekeil

Replying to @DMTaino :

I've only had a small multicolor print since installing it. There were no problems there :)

This seems to have fixed my AMS issue with retracting filament for the spool in A3.

After many AMS slot 3 retraction issues I printed this successfully, however eventually solve the issues using other models that cleared the path of the ptfe tubes outside the AMS, I’m keeping this in case issues will return.
