Cura 4.6.2 - Spiral shapes make slicing get stuck half way

Recommended Posts

Posted (edited) · Cura 4.6.2 - Spiral shapes make slicing get stuck half way

More in included project file


So, I wanted to print this: https://www.thingiverse.com/thing:3364860

But when I start slicing the HairSpring or the MainSpring files (the MainSpring is rotated incorrectly, so you have to turn the objet upside down), it gets stuck half way through the slicing process progress bar. However, when I rotate the spring 90° or 180°, so it uses supports, it slices it in less than 10 seconds. I have no idea where is this problem comming from. I encountered this in Cura 4.6 and updated to 4.6.2, hoping it would make a difference, but it didn't. I have no idea what's wrong with it. I reckon it has something to do with the spiral geometry of the model. I likely can get around this by using Slic3r, but if anyone finds out what the problem is, that'd be great. Thanks.



Edit: just noticed that if I make the spiral not touch the build plate, it works just fine, but raft doesn't work, you must lift it manually so it fills the gap in with supports. Still got no idea what's the problem tho.

      • 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
