Description

I've encountered several challenges when feeding filament through the AMS while printing in multiple colors. Frequently, the filament becomes obstructed in the buffer region and subsequently rewound. To address this, I manually handled the filament (detaching it from the printer) and observed that if the infeed tube isn't perfectly aligned during insertion, it triggers a rewind after a brief pause.

To rectify this issue, I 3D Designed my take of a Ptfe guide (there are others out there but this is my version) to, ensure proper alignment. This modification has significantly improved my printing experience, and I've had no further issues with color changes.

v2.1 update:

I have now created a no support version which only requires a brim ! additionally i have added Chamfers to both in inlet and outlet to be more smoother

didn’t really stay put when assembled.

that's strange this is the first comment about that. it should be able to stay pretty well once its pressed . even if it moves slightly it's still keeping the ptfe straight. maybe your ptfe tube is too short?

@aminimumoxie

i think it is doing its job. I just thought it would nest more in the AMS unit.

I had an issue with the filament getting stuck and retracting at the buffer, especially when using cardboard reels with printed covers. However, I'm happy to report that this issue has been resolved..

printed well, perhaps a little overdone with the supports. Just a suggestion,if you taper the back side of the model it could int the other way up with only a brim.

The designer has replied

@Bas7ard

hi Rick thanks for your suggestion. I was allready making alterations and that was one of them along with chamfers . I have added them now
