Description
Bambu Labs new 4-in-1 filament hub is a great upgrade, fitted to the top is where it was designed for but I've adapted my Top Mount to move it behind the Buffer. In this position it replaces the more expensive Hub that allows for up to 4x AMS chained up. The advantage also extends to dry boxes and other external feeds. In this set up it has added functionality as the Buffer will “read” there is external feed when filament is fed into the Buffer if the AMS hasn't been triggered. I designed this to be a fit and forget, there are no permanent changes also. So more printing and less fuss.
Parts Required:
- 4-in-1 filament hub
- 40mm length of PTFE (4-in-1 to Buffer)
- 2x M3x8mm screws for Buffer Spacer to Printer
- 2x M3x8mm screws for Buffer Plate to Spacer
- 1x M4x8mm screw to attach 4-in-1 to Buffer Plate
Installation:
- Remove Buffer
- Install Spacer Plate with 2x M3x8mm screws
- Install Buffer Plate to the Spacer with 2x M3x8mm screws
- Fit 4-in-1 to Buffer Plate
- Install the 40mm PTFE into the forward end of the 4-in-1
- Align Buffer to the 40mm PTFE and locate tab on Plate/Buffer, the two original screws fit the Buffer
- Reconnect the Buffer to Printer PTFE and then your choice of inputs on the 4way

the spacer plate seems a bit off for me (bambu pla-cf black)

Oh thats weird. Does the buffer plate line up with the spacer if you lay it over the top? Ideally they should both be the same dimension screw holes.

The buffer plate lined up fine, i ended up grinding a little bit out of that screw hole to get a decent fit to the printer

the other screw hole in the spacer was a bit off too. seemed like the holes in-between for the existing screws weren't quite in the right position (i ground those out a bit too)

Two AMS are running successfully, and they can also successfully recognize when the external material tray is inserted. It's a very useful design.

Thank you for your feedback comments, I'm happy it works well for your setup. Cheers for the rating and most humble thanks for the BOOST 👍
*Just a quick note, I can see the spacer plate is bowing out, this is usually the bolthead not seating in the recess properly which can be improved with a little cleanup of the hole (its a tight tolerance). No dramas, just for my OCD :))...

Perfect fit. Works flawlessly and has saved me some money. What's not to like? Excuse the super rough print in my picture, I used some leftover filament that's been sitting out for years and hasn't been dialed in whatsoever. The actual print profile makes for a much better quality, but since it's on the back of the printer I didn't care.

Way to go with the economical use of scrap filaments 👍 I've usually thrown loose spools towards plates of my filament clips (wink wink). Thankyou for the feedback, rating, and generous BOOST :)

Printed great! Not sure why the “cap” is needed I didn’t install but it still works really great! definitely recommend for anyone that is using the 4x1 installing on the left side. it worked great!

The cap is to help get the PTFE tubes out, depress it while pulling the tube out. I found some can be difficult and it helps to press the tube in before pulling out (lets the grip release). Thanks for the feedback and rating anyhow :))

I'm guessing this is a reupload? I printed the old one out last week and it's working great. Glad someone made one for this version as all I was finding it ones that used the Lite version.

I like this version, fits up well and works with the Buffer/AMS. Thanks for the comment :)
*Yes my small collection is back with some updates. I’ve had someone rip a few models off and there were a few words exchanged with BL about it. Have sorted it now.

Can this be used behind the buffer with just a single spool, or only with another AMS? If it's a single spool, how does the printer know which spool to use?
The designer has replied

Yes, it can be used by one single spool with no changes. The great thing I found was when you manually feed a filament through this way is once you push the filament to the print head the printer knows it’s an external and lights up that on the panel. You can configure it any number of ways.

Can I kindly ask you the real differences in the display when mounting it before the buffer? maybe with a photo.. because by feeding without buffer I can still set it.. I don't understand the benefit... I would like to understand before venturing into the change because I have the printer in a very awkward position... thank you very much

When you feed a filament (from an external spool) through the Buffer it reads that and when the filament reaches the Extruder filament sensor it completes the circuit for the External Feed and shows the Feed line as Active on your X1C screen. It won't feed from the AMS whilst this Line is active. You still have to push the filament into the extruder gears to achieve the full effect still, it is still manual with the "Load Filament" but automatic in the selection of the Spool being used. Pictures are easier :)
Feeding after the Buffer (to the top junction for example) it won't recognize the filament until you press load for the external spool.
*I'll get some pics soon, my AMS is out-of-order with a board fault (parts here today).

I did have to do some hand carving to get some parts to clear otherwise it is an impressive idea that works very well.

Could you tell show me whereabouts? I recently resized the Spacer plate due to a mix up with an old upload. The current one should have fitted. Thanks for the feedback and rating :)

you made me think a little bit about this whole star business with this feedback. I now realize it's kind of ridiculous. Your ideas awesome so it doesn't matter if I had to do a little modifying. Without you posting the idea and would have never thought of this on my own.
The two black bumps on the back of my 3D printer were a little bit off from your part. I suggest adding at least 2 mm all the way around, including additional space in depth of the cutout space. Clearly there must be some variation in manufacturing.
This is such an awesome idea as it saved me money. I didn't have to buy that multiple port thing they offer. Thank you!

I really appreciate the feedback, as I've had issues before with the spacer and adjusted it. I've taken it back and done a revision now and opened the holes a smidge along with centring the Plate over it. The back panel should be reasonably generic but maybe my tolerances were a bit too tight :)
I am happy to hear it fits your needs at the end of the day. Cheers 👍

will this mod also work for printing tpu through the buffer? as this is probably the main reason to instell the splitter for me
thx

You can feed the TPU on an external or drier through this setup yes. Not through the AMS. I've run TPU in this configuration from the external and its fine.
