I really want to avoid getting into the rabbit hole of having all the build deps to compile prusa slicer so while waiting for a fix here's an all command line workaround that still works even if prusa-slicer gui is crashing: openscad -o model.stl model.scad prusa-slicer -g model.stl curl -F "select=true" -F "print=true" -F "[email protected]" " http://your-server-ip/api/printer/upload?apikey=YOUR_API_KEY";
I do however wonder what was the reason for releasing prusaslicer-2.9.4p2 when the previous version was working ? I do see a snapshot version https://ftp.hostserver.de/pub/OpenBSD/snapshots/packages/amd64/prusaslicer-2.9.6.tgz I wonder if that can be used on 7.9 ?
