Select Filament For MMU Remotely  

RE:

Hi, sorry there's not. In the filament selection screen, the printer stops responding to commands. You would have to modify the gcode to use the appropriate T command to load the filament you want and remove the one which asks you which one you want. Then the purge still requires user interaction and there are no plans to automate that. Sorry, there are no plans to improve that on the MK3 generation

Hey @tojik,

I put in a feature request to Prusa. Hopefully, it will work.

RE: Select Filament For MMU Remotely

Great, you have reached me. Just another way. It's not that I want to block your feature request, we have gone over the possibility of such feature with the FW team before. Unfortunately this feature will not exist on the older style printers unless something extraordinary happens. Sorry about that

RE: Select Filament For MMU Remotely

This makes me very sad because there is no point in PrusaLink or PrusaConnect if MMU users cannot select filament remotely. However, I understand where the FW team is coming from (I am a coder myself) and I just wish there was a way to make this work.

RE:

You can probably work around this by slicing on the full mmu profile and using only a single material. Or is there a problem with doing that? Does it still print the wipe tower? Or does it get by "wiping" to infill?

RE: Select Filament For MMU Remotely

Hello together. I had the same problem when selecting the "MMU3 Single" Profile in PrusaSlicer. Now I just have to select the normal "MMU3" Profile and coloring the whole Model in one Color and selecting the extruder. So I can confirm that the Purge Block will not be Printed and when you press ready in PrusaConnect the Printer starts automatic and select the right filament from the MMU3.

Hope this helps 🙂

RE: Select Filament For MMU Remotely

Thank you for confirming this

RE: Select Filament For MMU Remotely

Hi everybody! 

I've read your thread, and it is to bad about the mk3s+. 
But I can say this:

Just recently I upgraded mine to a MK3.5 and the MMU2s i had to a MMU3. 
Except for the X axis failure of calibration and a little trial and error to get the right nozzle temp to melt enough filament, I am really happy with the improvements. 
Well worth it for the speed and convenience of the new Buddy board 🙂

Back to topic:
How about choosing the correct tool on the MMU3 from Prusa Connect to do a single-filament print? 
Is that something that will be in the future for the MK3.5/MK3.9 and MMU3 combo?

Also, I can't seem to figure out just exactly how I can start a print with pre-defined and pre-loaded materials in Prusa Connect. 
It seems like I have to use the LCD on the printer no matter what I do to the settings in PrusaSlicer.  

RE: Select Filament For MMU Remotely

Hi, that'S weird, for normal non mmu prints, this should be as straightforward as hitting upload and print. What exactly do you have to do on the LCD that is stopping you from printing from PrusaSlicer alone? Thanks

RE: Select Filament For MMU Remotely

Hi,

resurrecting this thread.  I also upgraded to the MK3.5 + MMU3 combo, and moved to Prusalink/Connect after having used Octoprint before. One feature I really liked was the MMU2 Filament Selector plugin ( https://plugins.octoprint.org/plugins/mmu2filamentselect/).

Do I understand correctly that this is not possible within Prusaconnect because it would need inline gcode modification by the firmware? With the above plugin Octoprint takes care of this I believe.

Thanks

RE: Select Filament For MMU Remotely

Same boat. Mk3.5 / MMU3, Prusa connect/Link and also used to rely on the MMU2 filament selector plugin for Octoprint. 

I can confirm that just using the standard MMU profile and painting it with the color of the filament I want to use, works just fine. I dont see a need for me, for selecting filament when starting printing. I could just slice the model again and select another filament. Not a big deal, for me at least.

RE: Select Filament For MMU Remotely

Indeed, this is what I am doing now as well. 

RE: Select Filament For MMU Remotely

The problem with slicing with a multi-material profile instead of a the single is that for items where the material type matters, when you've changed which feed the materials are in, you need to reslice and push the new item.  

When printing the same item numerous times, consider hundreds of prints, being able to select from the items in PrusaConnect save time and effort from a production perspective as well as management of the files in PrusaConnect and on the printer.

This does not need a firmware update, OCTOPrint has a plugin that lets OCTOPrint do this.  Given that, it means it can be a software update to Connect/Link.

It's disappointing that you are not considering this, as this impacts anything using MMU and Connect (MK4/CORE One), which are your new printers.

Regards,

José
