Cura, OctoPrint and a Raspberry Pi


Recommended Posts

Posted · Cura, OctoPrint and a Raspberry Pi


I know all three very well and use them for a long time but I never actually combined them. I have read that it is possible to install Cura (or at least the slicing engine) on the Raspbery Pi, upload a slicing profile and have stuff sliced on the Pi then used directly in OctoPrint.

Does it work? And how well - or rather - how fast? I'd imagine slicing on the Pi to be super slow. And apart from that you can't position objects interactively like with desktop version of Cura and you'd have no layer view.

Is this practical?

    Hi Nico,

    I tried it some month ago. As resume I would say:

    - the slicing is not as slow as I thought (but even not very fast ;) )

    - the Raspi is not really that power machine for such tasks ...

    - you must believe on the slicing profile and have no real control over that whats going on (o.k. you can review the sliced file in gcode viewer ...)

    - for me a good workflow looks other

    After that I decided to stay on my old workflow slicing with cura on desktop and send the files to octoprint - for that I tweaked the 15.04 cura in a way that I have a "Send to Octoprint" Button near the "Save toolpath". So I mustn't save the file locally and upload it to octoprint, it is send directly (using octoprints API). And as a bonus you can configure Octopint in an way that it starts printing new uploaded files immediatly (if no other print job is ongoing).

    For me (so far) the easiset and fastest way ...

    Regards Bernd

    First at all:

    I'm not a python-coder, so some things may be not as "clean" as the could be ;)

    The changes are tested and work in my configuration / on my systems.

    It's only tested on Ubuntu-Linux.

    No gurantee that they will work also in other configurations.

    In Octoprint are no changes needed, you have just to enable the API and CORS in "System -> API".

    The API-Key is needed later on.

    The changes in cura are in the "sceneview.py" (download here ) - on Linux to find in /usr/share/cura/Cura/gui/

    All changes I made where commented ###.

    In this file you have to adjust the following to meet your environment:

    around line #143: url

    around line #154: X-Api-Key

    With this changes you have an additional button near the "YM" button that sends the actual file directly to Octoprint.

    Have fun

      • 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
