I 've been using Mach for a number of years on a CNC mill I built , and never had any issues getting it full screen.
I'm in the process of building a CNC plasma table, and have just downloaded on a different computer but cannot for the life of me get it full screen. Also, the text is not as crisp as the one on my mill.
I have searched here as well as Google, but can't find an answer.
Thanks
BTW, I did go into General Config, and made sure that "auto screen enlarge" was checked off.
