I was trying to machine a shaft 1.0 diameter and turn it down to .500 and one in length in -Z .I put a start point of x-.5 ,z 0.0 a finish point of x -.250 z-1.0 .And the software said that the vales for x and z are incorrect for id/od .I changed the values for a top turret and it gave me a code .So the routine is set up for a top turret machine very strange that it wont let have a boot turret?
