Create a new Postprocessing Script

[Cuq 111]

Hello,

 

I'm trying to create my own postprocessing script. The goal of the script is to add at the beginning of the GCode file different comments to keep the print profile.  For the print parameter I don't have anny problem to get the values , but I don"t know how to get the Name of the profile and the initial material name.  I'have made a test with a command line like :

GetValStr = Application.getInstance().getGlobalContainerStack().material.getMetaData().get("material", "")

but this line return an empty value.  hereafter the actual sample code 

import re #To perform the search and replace.

from ..Script import Script
from UM.Application import Application #To get the current printer's settings.
##  Performs a search-and-replace on all g-code.
#
#   Due to technical limitations, the search can't cross the border between layers.
class Documentation(Script):
    def getSettingDataString(self):
        return """{
            "name": "Documentation parametres",
            "key": "Documentation",
            "metadata": {},
            "version": 2,
            "settings":

                    "default_value": ";FLAVOR:Marlin"

This is beyond my knowledge but maybe @burtoogle or @ctbeke or @ahoeben can help or at least know who can.

[ahoeben 1,657]

A printer has one global stack that has common settings, but it typically has no materials. A printer also has one or more Extruder Stacks. You need to get the material from the extruder stack. This might work (but I have not tested it):

GetValStr = Application.getInstance().getGlobalContainerStack().extruders[0].material.getMetaData().get("material", "")

There are other settings that you should be getting from the extruder stack too, like material_diameter, material_flow, retraction+*, material_print_temperature, machine_nozzle_size, infill_*, speed_*

 

There's a lot of code duplication in your script. You don't need to get the global stack over and over again; store it in a variable.

For the the majority of these parameters ( material_print_temperature, machine_nozzle_size , material_diameter etc ) . GetProperty function retrun the right values.

GetVal = Application.getInstance().getGlobalContainerStack().getProperty("machine_nozzle_size", "value")

But I don't find any parameter for the profil name  and the material base. 

 

GetValStr = Application.getInstance().getGlobalContainerStack().extruders[0].material.getMetaData().get("material", "")

Doesn't seems to be a valide solution

[Cuq 111]

Ok step by step I'm closer to my goal   to get the Material name I'm using this code :

 

        # add extruder specific data to slice info
        extruders = list(Application.getInstance().getGlobalContainerStack().extruders.values())
        GetValStr = extruders[0].material.getMetaData().get("material", "")

 

Does anyone of you knows how to get the Profil name ?

Sorry, GlobalStack.extruders returns a dict, not a list. You could try

...getGlobalContainerStack().extruders["0"].material.getMetaData().get("material", "")

For the profile, try this direction:

...getGlobalContainerStack().extruders["0"].qualityChanges.getMetaData().get("name", "")

AND

...getGlobalContainerStack().extruders["0"].quality.getMetaData().get("name", "")

Use the quality one if the qualityChanges one returns empty.

Thank you @ahoeben !!!!   That's OK :

• Profile name
• Material name
• Quality

        # add extruder specific data to slice info
        extruders = list(Application.getInstance().getGlobalContainerStack().extruders.values())
        #   Profile
        GetValStr = extruders[0].qualityChanges.getMetaData().get("name", "")
        GetLabel = "Profile"
        replace_string = replace_string + "\n; " + GetLabel + "                      : " + GetValStr        
        #   Material
        GetValStr = extruders[0].material.getMetaData().get("material", "")
        GetLabel = "Material"
        replace_string = replace_string + "\n; " + GetLabel + "                     : " + GetValStr
        #   Quality
        GetValStr = extruders[0].quality.getMetaData().get("name", "")
        GetLabel = "Quality"
        replace_string = replace_string + "\n; " + GetLabel + "                      : " + GetValStr
