Quick disconnect for the bowden tube on the ams

Good Day,
New to the forum. Look forward to sharing ideas.

One of the first things I did with my X1 is change out my .4mm nozzle to .6mm (The new universal standard).
To do this I had to access the system through the top. As you know, you can easily unplug the electrical connection to the AMS and you can pull the bowden tube out of the AMS.

The documentation to change out the nozzle was excellent. (Nice job Bambu)

So I just have to reinstall the AMS and I can get printing with my new nozzle…not so fast.
The electrical connection easy.

But I could not get the Bowden tube to seat properly in the AMS…I literally had to disassemble it to get the Bowden Tube to seat so the filament would feed. What a nightmare.

On the other side of the back there is a disconnect when you want to use single reels of filament.
Bambu you should put that on both sides especially to the AMS which needs to be taken off and reinstalled for any access through the top.

Thanks for listening.

I didn’t think you could disconnect the AMS tube. I have always disconnected at the buffer. The buffer connector is a little down a hole so a simple tool is helpful to depress the collar.

Not sure where I read that, but that’s what I did and would not recommend that anyone do that!!!.
If you look at the quick disconnect on the other side, thats what should be on the Tube coming from the AMS…Charge me the extra $2.99 please.

Cheers.

Do you mean the tube as show in the fifth video on How to remove the different PTFE tubes to help clear a broken or blocking filament | Bambu Lab Wiki around 16 seconds?
It explains that you need to press the black connector.

I had to remove that tube because of some stuck filament. Removing it wasn’t the problem for me. Somehow I did not push it back in well enough when I was done and reassembled the AMS.
So the PFTE tube got pushed out during the first filament load (and the AMS kept loading filament because it never reached the extruder. And loading. And loading… lets just say I was glad that I was in the room during that moment…;-))

At the second attempt I could get it reinstalled to the AMS again, just had to make sure I pushed it in far enough.

It isn’t hard to disconnect the tube at the AMS once you figure out exactly what you’re supposed to push. Getting it reinserted, though, can be frustrating as you can’t see where the tube is going and a little bit of curl will cause it to miss the hole.

Thats all true pulling it out is easy…push the button and pull. But getting it back in right is a bear…a quick disconnect on the bowden tube is the correct answer.
Does anyone know where to buy those? They are not listed as an accessory on the Bambu site.
Thanks.

Glad to hear I am not the only one…I could not get it pushed back in far enough or in the right spot without taking the AMS apart…
Do you know where to buy a quick disconnect for a Bowden Tube like the one on the other side of the back of the X1?
Thanks.

If you want to print from external spool, you don’t have to disconnect the AMS anymore.

“To do this I had to access the system through the top” ??
Why is that ? You can reach the two screws from the front ?

Patience is a virtue …

I’m not sure which one in my picture that put up a fight but I’ve certainly had worse

As for the disconnect for bypassing the AMS I tried using the Y splitter which printed great but I just didn’t like the travel of filament when doing multi material prints with the AMS so I just stick with uncoupling the Bowden tube from the AMS on the side closest to the edge of the printer body (left side from the front, right sight from the rear) and run a small 4 inch piece in its place to keep the filament running smoothly to the hotend

A bit overkill but better safe than sorry and I’ve never had a jam or feed issue yet


:crossed_fingers:

How do you route the filament?

My system is on a stand that makes the unit very easily accessible while standing up and working from the top. It just seemed like the easiest way to get to the nozzle…and I was right it was great changing it out and unlike changing out my nozzle on my old Creality ender 5 that is in its enclosure, this was easy peasy.

I’m actually doing a TPU print right now so good timing on your question

I’ve actually printed like in the picture many times as I experiment with different brands of TPU

Feeding it to the extruder isn’t as bad as you think

First I home the print head

Second I feed the TPU alllllll the way through the Bowden tubes to the extruder (you can feel it stop)

Next using the touch screen I manually put the print head over the chute in the same spot it purges filament

Next step heat the hot end to 230°

Then once again I use the touch screen to manually extrude until I’m satisfied with the purge (if you’re touching the extruder with the filament it grabs easily when you manually via the touch screen extrude but I find that I’ve got to tap the button quite a few times to continually keep the extruder going, would be nice if we could put in a value through the screen like 50mm)

After that I zero out the temp for the hot end and once it drops to about 210° turn on the part cooling fan for a few seconds

Finally I manually bring the print head forward to about mid way

Lastly hit home again then I’m ready to send a file

It sounds like a lot but it’s not lol

Thats very cool. Thanks for sending that pic over.

I don’t know of a more user friendly quick release mechanism that will fit on the AMS side.

I marked the PFTE tube with a sharpie/highlighter at the spot where it reaches the outer edge of the AMS hole so that I have more certainty that it is fully inserted when I need to remove and reinsert it in the future.
But I will only remove it if is really needed otherwise I also go for the approach that Jrock has shown.
