I recently purchased a 6040Z 4 axis router mill. Everything seems to work correctly and have ran several programs verifying everything. But when I use the rotary axis (axis A),using code G1 F10.0 A90.0 the axis seems to act like it is moving 90 inches, instead of 90 degrees. I cant seem to find a setting to change this issue. any help would be greatly apricated. thanks.
