Multi-axis slicing for a tilting and rotating base

Posted · Multi-axis slicing for a tilting and rotating base



We are working with a device that can rotate and tilt the base while printing. 

I am wondering if anybody has explored the changes necessary to the CuraEngine in order to support more than 3 axis?


I've seen the auto placement plugin using the tweaker python code which looks interesting.


Can somebody provide pointers on where to look in order to solve this problem please?


Thanks for any assistance.

    Wow.  That's not built into cura but you could write a plugin to do that.  You would apply a transform to all the G1 and G0 commands depending how much you have rotated or tilted the base.  The easiest kind of plugin isn't called a plugin - it's called a post processing something.  I think there are samples you can look at.  If you can't find one I can send you a sample.

    It depends a lot on what you need.


    If you need to transform the g-code into something that's better understood by your printer, then a post-processing script could do the job. But if you need to do something different depending on, for instance, whether you're printing overhang or not (to maybe tilt the platform a bit to get better overhang), then you're almost certainly stuck with modifying CuraEngine itself, or you'll have to try and reconstruct from the g-code which areas are overhang.


    But if you're actually going to try to print curved layers and such to print something from inside out, well, I don't think that Cura will be of much use at all.

    I have some experience abusing Cura for “weird” printers; I’m working on the Blackbelt version of Cura, which supports a slanted gantry.



    Your printer sounds a lot more complicated than theirs, but I see possibilities.

      • 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
