I finally got everything up and working, thank goodness!
 However, I have a project file that involves drilling several holes down the length of an 18" board. When I run the file, the machine seems to assume that the board is placed horizontally on it. It is a CNC 6040, which is approximately 19" wide. Therefore, there is not enough room to drill the holes with the spindle going side to side.
 I need it to assume the board is placed in the machine along the the length, not width.
 Is there a setting in Mach3 so I can change the direction of the board and the machine will recognize this?

On the MDI screen is Local System Rotate, just enter 90 (or -90) and that should do it. Please be aware that your datum will also be moved.

Tweakie.
