Hi Bucks,
Unfortunately, through no fault of your own, you have been duped by the supplier of your new CNC machine and you have installed a Pirate Mach3 License (Licensed to...MaoA˜A ¯Ðtonar).
The recommendation is that you document all of your configuration settings........... every one of them. Do a clean install of the OS, download Mach from our site. Install it and configure it for your machine following the install and config. Guide.
