Hello (First post), please send me in the right direction

1. No, the ISO has everything in it.
2. www.linuxcnc.org/iso/linuxcnc_2.9.1-amd64.hybrid.iso

Just to clarify, the ISO Tommy linked to uses the Debian Installer with our applications added. There should not be anything different to a mainstream debian installer.

This is my first post too and I am a complete beginner as well. I am working through the John Hildreth series of videos which are now 6 years old. He uses Debian Wheezy but advises that one should use the most up to date version. If I follow the link above will that now download the latest version of Debian which I think is Bookworm, as well as LCNC? I have been promising my self that I will learn Linux and as I am a CNC hobbyist this is the start of an exciting adventure.

The latest is the 2.9.3 ISO that is linked in the Downloads page.
