Cura 4.8.0 freaking out and crashing when attempting to preview


Recommended Posts

Posted · Cura 4.8.0 freaking out and crashing when attempting to preview

Just got a CR10S Pro. Pulled in about 6 parts that I don't believe should be taxing the slicer. I'm using standard extrusion settings (.2mm layer thickness), and a 3D-Fuel Pro PLA filament profile that is the same as PLA except for the bed and extrusion temps. Seems to slice fine. I also added a brim with its standard settings. But when I go to preview, Cura either hangs, or it literally displays strange disorganized graphics on the machine that are reminiscent of a 1990's video card freeze / hangup. I am running the absolute latest Mac OS on the latest M-chip Mac Mini. Cura 4.8.0 seems to have an issue here. I will upload both the project file and a screenshot of the kind of thing I see when trying to preview.


When I hit preview, a pop-up says "Processing Layers 99%", and there it stops and hangs. Sometimes it takes my entire computer down with it (computer nonresponsive). However, you should know that I access the Mac mini remotely, and it may be that Cura is taking out the remote desktop software, not the entire OS. I can't tell because I'm not using a keyboard attached to the Mac.


Cura has always worked fine for me. I also have Cura on a 2012 Mac Mini running Catalina, so if this keeps happening I'll switch back to the old computer for a while.


I have attached the Cura project file, saved just before I start slicing. I have attached the screenshot of what Cura does when I try to preview after slicing.

    I should add 2 things:


    1. So far Cura doesn't do this with other parts. It is only freaking out with this project file. 


    2. If I save the .gcode file before preview and print it, it's printing fine on the printer. So the slicing was successful. What isn't successful is previewing that slicing.
