Today I did the fresh installation of Windows7 ultimate and the mach3 software. It is still giving the error G CODE OUT OF RANGE: BLOCK G80 M108. Give the solution for this trouble?

Delete both the G80 and M108 from the Initialization String.

Hi Gerry,
Today, I tried a new Mother Board (brand and model same but used old RAM, Proc and all other stuff) and saw that it is working. Even HardDisk was of same old installation (no new installation of either Win7 or Mach).

I'm not sure what is the hardware dependency. Maybe something is coming in the way (which may have gone bad). Any idea?
