Model Specific Settings - override Extruder used

[joeman1556 2]

Hi,

IF we have say a 4 extruder printer (1,2,3,4) 

 

1 is outline for MODEL 1

2 is infill for MODEL 1

 

3 is outline for MODEL 2

4 is infill for MODEL 2

 

 

Can this be done?

 

 

Thanks

Yes.  I'm pretty sure you can.  You can definitely have 2 different models with extruder 1 for one model and extruder 2 for the other.

 

You can also specify that the infill (or support also) can be done by a different extruder than the shell.

 

I'm not sure how to do 4 extruders but I think it's possible.

Within Settings for EXTRUDER 1 I set INFILL override to #2.

 

Then I go to EXTRUDER 3 and notice its' INFILL override is set to #2. I change this to #4...

 

But this changes the override for INFILL for EXTRUDER 1 

 

😞

 

 

When I go try to do it by Model...it doesn't give me option to override 😞

I've noticed in one of the json config files..

 

 

                "infill_extruder_nr":
                {
                    "label": "Infill Extruder",
                    "description": "The extruder train used for printing infill. This is used in multi-extrusion.",
                    "type": "optional_extruder",
                    "default_value": "-1",
                    "settable_per_mesh": false,
                    "settable_per_extruder": false,
                    "settable_per_meshgroup": true,
                    "settable_globally": true,
                    "enabled": "extruders_enabled_count > 1"
                },
 

So, this probably explains what I'm seeing.

The infill extruder is not defined per extruder, but per model (the same way as the assignment of the main extruder).

According to the shown snippet - "Infill Extruder" should be selectable as a "per model setting".

Lovely. I'll have a play around with it.

 

I did try :-

                "infill_extruder_nr":
                {
                    "label": "Infill Extruder",
                    "description": "The extruder train used for printing infill. This is used in multi-extrusion.",
                    "type": "optional_extruder",
                    "default_value": "-1",
                    "settable_per_mesh": false,
                    "settable_per_extruder": true,
                    "settable_per_meshgroup": true,
                    "settable_globally": false,
                    "enabled": "extruders_enabled_count > 1"
                },

 

 

But I'll play with your suggestion...get a better understanding.

 

Many Thanks

Joe

Setting just...

 

 "settable_per_mesh": true

 

did the trick.

 

I can now select the extruder for INFILL "per model"

 

Lovely!
