I mentioned before about the screens and was taken to task by an experienced Linux user who told me it was quite simple and sent me three pages of code to alter the screen but no instructions on what to do with the code or where to put it.

OK to him that was simple but I don't even have to write G Code in this day and age.

It would be nice to just get a system that loaded up and ran but why cannot they do this after all these years ?

As regards CV, a friend of mine who is a programmer, looks after windows and linux systems has this on his machines as well as Mach.

He's done tests and filmed then using same file, same machine, same code, same everything and M3 outperforms LinuxCNC on his router, you can see it slowing for corners.

However on his lathe LinuxCNC beats M3 hands down, especially as M3 is useless at threading with the one slot encoder.
