Hi,
this post should be in the main Mach4 Discussion board.
The problem is when I come to run a program my Z axis travels up in the positive Direction
I don't have anything like your experience however in my experience a move in the positive direction is upwards.
I would expect the work co-ordinates to be zeroed at the surface of the material so a positive work coord is above the
material and a negative coord is below the surface, ie cutting. To my knowledge this is also the standard convention for
CAM programs.
You can either reverse the Gcode or reverse the direction of the Z axis.
