Generic external postprocessor with a command line


Recommended Posts

Posted · Generic external postprocessor with a command line


I am experimenting with speeds and tri-hexagon gradual infills on my printer, and I need to tweak some parameters not available within Cura, namely reduce the speed of the last few infill layers.

It looks like the best solution would be for me to write a post-processor plugin that patches the gcode.

Postprocessor plugins seem to be easy to integrate inside Cura (for example, ZOffsetPlugin is quite readable). Unfortunately, they are written in Python which I do not master, while being quite fluent in C++ & JavaScript.

So, is there a standard universal postprocessor plugin, able to pipe the gcode to stdin of a process and get the patched gcode from the stdout, in the great Unix tradition?

This would allow me to develop this processor in an environment that I am familiar with.

    Problem solved: I adapted the Cura-Slow-Z plugin from @5axes in order to allow having a specific speed for bottom layers infill.

    This allows for printing bottom layers at high speed, but top layers at low speed so that the large gaps of tri-hexagon infills are filled correctly.

    This is a quick and dirty hack but which makes the job. It is available here

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
