Have you solved the problem?
My Parts arrives after and after.

Nope never got working

Sorry I don't have access to the boards right now. I tried the firmware I uploaded, and have the same issue. The MMU boots, but printer does not see it. Not sure what needs to be changed, but for the moment I am afraid that you will need to be able to compile this locally on Arduino 1.8.5 to upload.

[rmilyard]

That sucks! I have it completely built but like said isn't seen my printer.

@rmilyard
Have you tried to print something with the new firmware without the MMU2? Does it work?

@cjbaar
Maybe something is missing in one of the firmwares?
The MK3s have to know that a MMU2 is connected and the MMU2 have to say “hello MK3s, here i am. Please unlock the menu.“.

At the beginning of printing with the MMU2, i had the same issue. The MK3s didn't saw my MMU2 several times.
This was before the 1.6 firmware was launched.
I had to resart the MK3s several times till it recognize the MMU2.

Got it all loaded. I will play with it more tomorrow. How tight use have idler screws?

@rmilyard
any news yet?

My last parts arrived today. now i'm ready the transform my MMU2 in a MMU12x :-)

[rmilyard]

@flinke-flasche I was able to get it to boot up. I haven't had time to mess with it. First try I couldn't get filament to load yet.

[flinke-flasche]

I set up my MMU12x. Everything works perfectly. I love it and it looks much better as the MMU2 :-)

@rmilyard do you think you can compile a multi language Firmware for the MK3s? i'm from Germany :-)

I use Octoprint for my Printers. Octoprint can't use only 10 Extruders. i do a feature request to Octoprint.

[cjbaar]

The MK3 firmware includes files for multi-language compilation, though I have not tried using them before. Unfortunately, at the moment, I have not put similar adjustments in the MMU display code.

As far as octoprint limiting filaments, I had similar issue with Prusa, which is why I had to modify the MK3 firmware as well. Not sure why these systems have so much hard-coding; it should literally just be forwarding on whatever you find in the g-code.

@rmilyard I only tighten my idler screws a couple of turns. I don't think it needs as much pressure as the original, but your results may vary.

@cjbaar
do you think you can compile the Firmware with multilanguage?

Maybe you can add a post at my Octoprint request.
OctoPrint/OctoPrint#4149

Can you tell me what the tiny numbers under the selected filament at the display is showing?

[cjbaar]

1. I don't have a working Arduino IDE 1.8.5 right now. I need to get something working again to compile these.
2. What is the issue with OctoPrint? I haven't used it much. Is it only sending G0-G9, so the last two filaments end up repeating filament color #10?
3. The numbers show total load/unload attempts and failures. Describe on the FW page: https://github.com/cjbaar/MM-control-01

I think it's just the Max-Value in the HTML5 Field in the template. I could just put in 12 and send it, and it saved :)

I haven't got my MMU Working as i'm waiting for Parts, so i couldn't try it out, but otherwise i'd open a pull request for that change in OctoPrint and also in the MMU2S Filament Selector Plugin.

@zonkie
You’re right. I can type it manually in the field and then it works perfectly.
I’ve tested it today.

bist du auch aus Deutschland?

@cjbaar
No more octoprint problems.
thank you for the display description.

i love your MMU12x.
thank you for sharing.
The firmware works perfectly for me.

I'm still waiting for parts... An m3 screw set and 10 of the 12 ordered u-shaped-bearings have arrived yet (thanks, ebay-seller, the bag is even labeled with "12pcs"...) Also some of the AliExpress things seem to have arrived in Germany, waiting for customs :) also i'm printing lots of spool-holders...

@flinke-flasche yes, i live near Hamburg :)
