Why Don't More People Build This Open Source AMS/MMU?

The CAN tutorial I put together should still work fine. The only thing that has changed is that the CanBoot Bootloader is now Katapult. However, all of the legacy commands still work as of a few weeks ago. (I used it when setting up CAN on another printer). CAN in general has quite a few pieces. Theres the method of setting up the network so U2C or CanBridge, the configuring the actual network, flashing the bootloader, and then flashing the firmware. Also make sure you have the 120ohm resistor in place or your toolboard will not be detected.

We choose to build an ERCF in this decade and do the other things, not because they are easy, but because they are hard; because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one we intend to win, and the others, too.

the encoder is to detect jams, the switches only detect there is filament but not if its moving the right direction etc, the encoder allows monitoring that, so if it isnt moving but all other switches are actuated then it knows there is a jam

You asked why anyone would want to watch a live stream after the fact. They are perfect to play in the background while doing the same project. It let's you know what is coming up next and you can pause/rewind/fast forward as necessary.

I love that you even covered the Blobifier! It's just a small addition to the system but seeing it appear in other people's videos makes me really proud! Thank you!

Oh really looking forward to the sv08 tool changer series - I'm patiently waiting for my SV08 to arrive.

I can't imagine how hard it is to build AND film all this. Thank you for doing it.

Dude, thanks for the video! I was there for a chunk of the live streams, you've put a ton into this and I know it's taken away a lot of your time from other videos. I bought one of these the day of your first live stream and I really appreciate all that you put into this. Good luck with the remaining work!

For CAN setup, refer to "Esoterical CAN BUS Guide"; is up to date and really comprehensive.

The thing with tip tuning is, that it is not just about the tip. Bambu printers are known for being VERY wasteful when swapping, because they have to push out the filament piece, that gets left behind after the cut. If you can cleanly extract and reinsert your filament, you are saving material and time on every single swap you do.

Building one too and have been for the last month, glad I am not the only one having trouble getting it to work lol

Thank you for covering this, I've looked into making one awhile ago but never found a vid i enjoyed with some one showing there journey building it. Great Vid

Awesome video! I've seen stuff about and looked into the ERCF before and I was always curious how it actually worked. Your explanations in this video were perfect! Thanks a ton! Looking forward to seeing it when you get it all working!

Not owning a Voron or an ERCF, you questioned the need for two runout sensors so close to eachother: I'm fairly sure it's because of the retraction. If you only have the one runout sensor at the multiple different units, when you're retracting to swap filaments you'd end up pulling up too far and not be able to use that one slot until manually reloading it. Having a secondary sensor in the actual selector allows you to figure out that "Hey, I'm now out of the selector, and the second sensor's not tripped yet. Good time to switch." The other side works the other way, it tells you you're running out at a point where you can still retract to swap and not get stuck.

Subscribed. I started getting into printer building and modifying after breaking my back over the last decade of building cars. I've got tinkering experience and a basic understanding of circuits as I was a master of automotive electrical systems. I started with an Ender 3 in 2022 and recently moved up to a Bambu P1S to print high-quality parts for the mods with the intent of using my Ender 3, which is no longer Creality except the frame and the bed, which just got the BTT SKR 3 EZ so I can run more steppers. I recently converted an old FlashForge Adventurer 3 to an open source setup running a BTT E3 Mini v3 and Klipper. I'm almost done with that build and looking forward to my first print on it. Next, I think I'm going to take on a Voron build or modify an old Ender 5 Plus for multi material printing.

Excellent video. This is an awesome project, and I'm REALLY looking forward to the 7 head tool changer. I had not heard of this before, and I'm glad you made a video of this. Thanks!

I think the complexity sort of answers the question of why no one's heard of the ERCF. I don't think I've ever seen one up and running without the owner being extremely nervous about how long it would stay that way. The rabbits are too enraged, methinks.

This project seems incredible

Amazing video! I have almost everything I need to add an ERCF, my hotend (XOL w/ ebb36) even has some filament cutters designed for it. Looking forward to you showing me how to troubleshoot it too!

I didn't even know you can build a 3D Printer from scratch. It sounds fun!
