OK , the problem is nothing is happening when I try anything, absolutely no communication with the engraver/router.
OS, windows 7 with absolutely NO other programs in the computer.
Mach3 and Planet CNC USB ?? are the only programs and the Planet one was only installed after I found that Mach3 wasn't communicating with the engraver/router.
I had installed the DEMO version of Mach3 in my MacPro and tried to run it using Parallels Desktop, but no joy. So I bought a recon PC with a fresh copy of Windows 7 installed. Installed my REGISTERED copy of Mach 3 and applied the licence. (My name comes where it's supposed to be)
The Engraver/router is the Chinese 3020T 4 axis (VEVOR Tack Hooks).
Using the USB or Parallel ports make no difference, there is no jog function or movement when I load a demo file. The File runs on the computer but that's all that happens.
What do I do please ?
