Posted · How to access material type (eg PLA, PETG etc) from Cura post-processing plugin?

Hello I have an idea for a post processing plugin that automatically adds the type of material used to the start gcode, this is so Klipper can interpret and add any filament specific settings like z height and pressure advance settings.

 

I have looked around, but I can't seem to find this data anywhere.

I did look through fdmprinter.def.json for it, but the only thing I could find was:

    "metadata":
    {
        "preferred_material": "generic_pla",
}

    Here's a neat list of replacement patterns you can use in the start gcode:

    http://files.fieldofview.com/cura/Replacement_Patterns.html

    Specifically, here's the ones for the materials:

     

    {material_id}   The id of the material (eg 'ultimaker_pla_blue')
    {material_type}   The type of material (eg 'PLA')
    {material_name}   The display name of the material (eg 'Blue PLA'
    {material_brand}   The brand of the material (eg 'Ultimaker')

     

    If you don't want to use replacement patterns in the start gcode, here's how they are defined in code:

    What does clipper need in the start g-code? You might be just able to do that with replacement tags

    I was going to add a String titled MATERIAL=%MATTYPE% and regex replace the %MATTYPE% using the post processing plugin, and based off that, klipper will ifelse to the correct settings.

     

    I could do this manually per print, but I'd rather have something automatic
