Hello,

I've wrote a plugin for Cura 4.x. This worked well.

Now, with Cure 5.0 I have to update my plugin. The only thing I have to change is the sdk version in the plugins.json.

So I set "supported_sdk_versions": ["7.0.0", "8.0.0"]" there, set the "Version" one up and uploaded the zip.

But then, I only get as eror message "null(null)" and the package is still in the draft status?

Can anybody tell me, where the error is? What did I wrong?

Regards

Daniel

Hi,

I developed a plugin for cura 4.

Now, with Cura5, my plugin is gone. Where can I find my plugin to update it?

A better place to store the plugin is inside the ````"plugins" folder in the Configuration Folder (See Help->Show configuration folder). Then you won't have this issue.

A propos, that is why I asked (twice!) where you place the plugin files.

The file are in a seprate folder in the plugins dir.

I answered that. I didn't realise that there is another plugin folder.

But I think its a bug in Cura. All the Plugins before the Console Logger are also not Logged. Perhaps the logging starts with the ConsoleLoggerPlugin? The Renaming this Plugin so it is loaded at first would make sense.

But I found another bug that crashes Cura completely.

Thanks for your patience.

Ok, found the source of my problems...

Cura registers the plugins in alphabetical order. The log starts at "C", the amf-reader was not listed in the log, but it was loaded. So I renamed my plugin-folder to something starting with "Z". And then I saw errors in the logile.

I had some missing imports. Thats all. After I corrected that the plugin was loaded fine.

My plugin simply was loaded before the logging starts.....

March 25, 2020

I start cura simply from windows with a double click on the icons.

What else do you need? I will try to answer the questions.

The source of the plugin is here: https://github.com/Spanni26/Cura/tree/master/plugins/ChituWriter

Ok, tried it now with the logger, but still no message in the logs:

from UM.Mesh.MeshWriter import MeshWriter #For the binary mode flag.

i18n_catalog = i18nCatalog("cura")

def getMetaData():
    Logger.log("w", "--- get metadata of ChituCodeWriter ---")
    if "ChituCodeWriter.ChituCodeWriter" not in sys.modules:
        return {}

    return {
        "mesh_writer": {
            "output": [

    else:
        return { "mesh_writer": ChituCodeWriter.ChituCodeWriter() }

Nothing in the logs.

I also have no such mime type in the save-as-dialog.

Frustrating...

Ok, thanks. Will try the logger.

The file are in a seprate folder in the plugins dir.

Hmmm, my Plugin seems not to be registered. I put a simple "print" to the register and the getMetaData function, but I can't find the output in any log.

Any idea?

March 24, 2020

No Prob, thanks. I will try to figure it out. Sadly, there is no documentation about that.

"file_formats": "application/x-ufp;text/x-gcode"

Note how application/x-ufp is in front of text/x-gcode

So, If I understand correctly: The file generated from ufp is "piped thru" the Script that creates the gcode? So with the order of the fileformats I can control the order the plugins are used?

Quote

Do you want to write multiple files at once (ie: a thumbnail and a gcode file in two separate files)? That is not something the MeshWriter supports easily. You would have to build that yourself.

Nope. There are only additional M-Commands included in the gcode-file. So I only wan't one file.

March 24, 2020

To Use the UFPWriter I have to "save as" and select "UFP"?

If yes, this is not what I wan't.

If I add a Tronxy printer the gcode simply has also "run thru" my plugin ans should be saved as gcode.

What sort of modifications are you talking about? Does the modified gcode file have to be named *.chitu? If not, it is easier/less confusing for the user to not use a meshwriter, but use something that simply post-processes the gcode when it is written.

It adds e.g. a Screenshot to the gcode so the part is shown on the touchscreen of the printer. The timestamps also have a special format.

I tried to submit a post process script, but they won't include it in the cura release. They advised me to write a mesh writer plugin and to submit it to the plugin database.

Hello, filename is "tronxy_base_extruder_0.def.json".

But it also failes if I set machine to "tronxy_base_extruder_0"

Hello,

I try to implement my own extruder definition.

But the test at github claims about a machine_id, which cannot be found.

{
    "version": 2,
    "name": "Extruder 1",
    "inherits": "fdmextruder",
    "metadata": {
        "machine": "tronxy_base_extruder",
        "position": "0"
    },

    "overrides": {
        "extruder_nr": { "default_value": 0 },
        "machine_nozzle_size": { "default_value": 0.4 },
        "material_diameter": { "default_value": 2.75 }
    }
}

E AssertionError: The machine ID tronxy_base_extruder is not found.

E assert False

Can anybody explain me this?

Regards

Daniel

March 24, 2020

Ok. Thats for testing.

What I wan't: if printer is a tronxy, the g-code should be created, that g-code hat to be modified by my plugin.

How can I do that? Is that done by "file_formats": "text/x-gcode;text/chitu-g-code" in the printers definition?

Sorry for that stupid questions, but I can't find any info about "Mesh_writer" Plugins.

Regards

Daniel

March 23, 2020

Sorry, here is the complete __init__.py

import sys

from UM.Logger import Logger
try:
    from . import ChituCodeWriter
except ImportError:
    Logger.log("w", "Could not import ChituCodeWriter")

from UM.i18n import i18nCatalog #To translate the file format description.
from UM.Mesh.MeshWriter import MeshWriter #For the binary mode flag.

i18n_catalog = i18nCatalog("cura")

def getMetaData():
    if "ChituCodeWriter.ChituCodeWriter" not in sys.modules:
        return {}

    return {
        "mesh_writer": {
            "output": [
                {
                    "mime_type": "text/chitu-g-code",
                    "mode": MeshWriter.OutputMode.TextMode,
                    "extension": "chitu",
                    "description": i18n_catalog.i18nc("@item:inlistbox", "Chitu Code")
                }
            ]
        }
    }

def register(app):
    if "ChituCodeWriter.ChituCodeWriter" not in sys.modules:
        return {}

    return { "mesh_writer": ChituCodeWriter.ChituCodeWriter() }

How can I be sure that the new mimetype is known by cura?

I don't see any signs that my plugin is used.

Regards

Daniel

March 23, 2020

Hello,

I wrote a plugin which I wan't to start by a new mimetype. But how do I register that mimetype?

My __init__.py in the plugins directory:

def getMetaData():
    if "ChituCodeWriter.ChituCodeWriter" not in sys.modules:
        return {}

    return {
        "mesh_writer": {
            "output": [
                {
                    "mime_type": "text/chitu-g-code",
                    "mode": MeshWriter.OutputMode.TextMode,
                    "extension": "chitu",
                    "description": i18n_catalog.i18nc("@item:inlistbox", "chitu addons")
                }
            ]
        }
    }

Is that really enough so I can call that plugin via the printers definition with

"file_formats": "text/x-gcode;text/chitu-g-code",

Regards

Daniel

Ok, found it. Specified Version as a string in a file in inherit.

November 13, 2019

Ok, done.

November 13, 2019

I've written a postProcessScript which add a preview and the time infos for the chitu boards.

How is the best way to get it ino cura? Is is in my private git repo.

November 8, 2019

But doesn't this biolate the GPL?

Atm. I have a Slicer with compiled pyc. I decompiled it, took the code I needed an made a PostProcessScript of it.

But I'm a little concerned of there reaction.

November 7, 2019

So there are no closed source cura versions for customer companies who bought and modified it?
