Cura 2.1.2 Prusa .json : double extruder possible ?

[Spilz 0]

Hello,

I'm using a Prusa I3 with 2 extruders.

I don't find how to create a printer .json file with double extruders and how to use it.

does someone know it ?

thanks for your help

regards

I found this :

 

"machine_extruder_count": { "default": 2 }"

in this topic

but I don't know how to use it.

My goal is to use the second extruder for soluble support.

2.2 will have greatly improved support for dual extrusion. You can probably get it to work with setting the machine extruder count to 2, but it will require a lot of tweaking / experimentation.

Thanks for your reply, I'm going to wait for 2.2

Actually on json file, it's only this parameter I have to add/change ?

Hello @nallath,

Can and be allowed they announce the release date for Cura 2.2!

If all goes well, open beta should be this week.

@nallath, and if not, will there be there at least a closed beta??

I´m also waiting hard to get my dual UMO productive again...

Hi,

I didn't see 2.2 relase, I directly find the 2.3 (beta) but I still not figure out how to add second extruder and select it for support :(

does someone find it ?

There was no 2.2 release, it went straight to 2.3 Beta

Thanks,

So what about second extruder ?

How to declare it ?

How to use it ?

Look in the json file for "Ultimaker Original Dual Extrusion", that one got fully functioning dual extrusion implemented.

If you use windows you will probably find it here:

C:\Program Files\Cura 2.3\resources\definitions\ultimaker_original_dual.def.json

I find the solution here :

https://ultimaker.com/en/community/22409-setup-custom-dual-extrusion-machine-in-cura-23-beta

it works well to add custon printer with dual extruder, but still not test to print with it
