RE: Core One MMU - Next Gen Solution

Thats looks decent!

So feeds into printer from where?

More simple without glass cut. 🙂

RE:

Looks like they snuck it in through the back right corner.  @p1r4m4x what did you use for a mount?

RE: Core One MMU - Next Gen Solution

Yes i used the pliers to slightly bend a bit the right corner and it follow the original swing arm path.

I made this MMU mount, you can find it there: https://www.printables.com/model/1334245-mmu3-holder-for-core-one

I like the fact that it doesn't distort the Core One.

RE: Core One MMU - Next Gen Solution

Very cool.  Have you had any problems not using a buffer?  Does filament fall off a full spool with a retraction?

RE: Core One MMU - Next Gen Solution

I use a printed auto rewinder without problems for now. The buffer is an OLD gen system we are in 2025...  🤣

RE: Core One MMU - Next Gen Solution

I have limited vertical room above my CORE One.  With your mount what is the total vertical height above the machine?

RE: Core One MMU - Next Gen Solution

@david-r-campbell the mount + MMU3 take only 12cm above the machine.

RE: Core One MMU - Next Gen Solution

Much appreciated.

I spotted this last night and saved on Printables. Was wondering, can you have 5 of these clicked together in a row? 

RE: Core One MMU - Next Gen Solution

I don't have any provisions in the model for securing them together but it would be a simple inclusion.

RE: Core One MMU - Next Gen Solution

Is there enough space in the buffer for the longer length that needs to be retracted on the Core One?

RE:

I am using it with my Core one so yes.  I have the MMU3 mounted using the Prusa MMU3 mounts, and I am using the Prusa supplied front PTFE tube

RE: Core One MMU - Next Gen Solution

So this Next Gen Solution looks very far off, but I'm in the need of a solution today. After looking at the Prusa website for MMU3 upgrades I do not see a clear shopping and printing list I need for the core one. Could someone help provide what they have done on a net new MMU3 setup on a core one?

RE: Core One MMU - Next Gen Solution

So you're not running down the PTFE that's attached to the swing arm?

RE: Core One MMU - Next Gen Solution

Yes. I am using the 710mm tube that comes with the Core ONE.  I just rerouted it from the filament sensor on the side panel to the front of the MMU 

RE: Core One MMU - Next Gen Solution

A hot end revolver with multiple extruders in one head unit. So that all media is already in a print state (liquified). 
2 options: multiple extruders in one head or one extruder with a revolver type hot end on top that can cycle through media all in fluid state. 

RE: Core One MMU - Next Gen Solution

You can't keep most thermoplastics above their glass temperature for that long of they will begin to break down.

RE: Core One MMU - Next Gen Solution

Ah ok. Then that’s no good. thanks.
