Open STL with 3MF already open goes off the build plate


Recommended Posts

Posted · Open STL with 3MF already open goes off the build plate



Not sure if this is a bug, but it looks like Cura doesn't know where to put an STL file when it is opened while a 3MF file is already loaded.

If the above iframe doesn't work (I don't expect it will and there's no option to embed any videos), the following link is to a screencast of the potential bug:




The first part of the screencast refers to the post linked below - opening a 3MF file places it at the origin contained within the 3MF from the exporting application; STL doesn't contain origin information. 


The second part of the screencast from 1:30 demonstrates what could be considered a bug:


  • When exporting a 3MF file from Fusion 360 and opening in Cura, Cura defaults to place the object at the same origin it was in Fusion 360, i.e. it takes the origin from the 3MF.
  • Exporting an STL file and opening in Cura always (normally) goes to the centre of the build plate.
  • When the STL file is already at the centre of the build plate (this isn't 0,0 because that is in the bottom left corner, but it is 0,0,0 in Cura world), opening the 3MF places it correctly at the origin, which is 0,0 (Cura world -110.0011,110,0).
  • But, when the 3MF is loaded first, the STL file is placed outside the build plate, on the right hand side, at 200,0,0 in Cura world.

      • 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
