I didnt find rufus user friendly.
I used win32 disc imager and downloaded mint from clive's linked site
Not being used to linux (never seen it before) it took me a while to find the linuxcncfiles and select lathe from the plethora of configurations , but I have it now with a desktop Icon.

Still puzzled a bit as to how to configure it though .

No problem for now as I need to finish the wiring yet and as I said before I will check this out using Mach 3
Then will come back for specific tuition on Linuxcnc
