CP v4.3.8 I can happily create vase/spiralise mode parts. V5.1.x gets almost to the end of slicing and the software just crashes, no error, just blink and it has gone. So I tried this on Orca this also crashes. My laptop is fine with it, an i7 machine, the machine I am on now is my workstation i9, both machines are nVidia graphics but this machine has an RTX A4000 workstation graphics card and I am thinking it might be that. I can slice any other model and print, its just vase mode that is an issue. Just tried Cura and like 4.3.8 it is quite happy.
