CURA 2.4 and Post processing plugins issue

Recommended Posts

the plugin is to determine the area used by the first layer to optimize auto-leveling

I never learn python, so I took exemple from other plugins.

it searches min and max X Y position of G1 command and replace a specific string of the start gcode by the optimized G29 L R F B command

It works well on my MAC with CURA 2.1.3

but not on my Win10 with CURA 2.4 : the list of post processing plugin show only one plugin when I had the file (normally it shows 4)

an other issue/question :

is it normal than even on CURA 2.1.3 the post processing is not saved when I reopen CURA ?

The API has changed between 2.1 and 2.3 - look at existing plugins to see what's changed (getSettingData vs getSettingDataString)

Yes, it is "by design"

Where could I find this folder?

 

At the place you installed Cura...

So for most people it would be: /Applications/Cura.app/Contents/Resources/plugins/plugins/PostProcessingPlugin/scripts/ (unless you installed it somewhere else)

 

... and where will Cura 2.4 be installed when installed(?) or run from Cura-2.4.0.AppImage-Install (the new Linux installer)?

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
