I have setup Mach3 with a new computer still running Win7. Everything is working and settings have been set for my cnc according to manual. However the hotkeys settings in Mach3 are set with the correct arrow keys and saved, but they move the wrong axis. I tried just changing the numbers for keys in Hot Keys on Mach 3, but it will not allow input changes that way. Any suggestions to the area I need to be in to match parameters to get the pg up, dn arrows to control the z axis, etc.?
