Thanks for sharing, Ghostkeeper!.
BTW, Does anybody know which Debian/Ubuntu version should be used with the above 15.04.6?
I tried to install it under Mint 20 Ulyana and the installer tells it cannot fulfill the dependencies...
Also with Ubuntu Focal Fossa and Tahr. After years using it on Windows and having tried most of the current advanced slicers, 15.04.6 still gives me the best printing times, and I don't need all those bells and whistles for what I'm doing.
Thanks in advance.
Jes.
