The way I align this machine is off the face of the turret for body to the z axis. To align the turret face you need a coax indiacator. Mount it in the spindle with a collet. Then sweep in a tool holder. Should be zero at the top and bottom of the holder. To adjust you need to take off the front plate/cover that has the station numbers on it. once off loosen the outer most bolt pattern. leave these kinda snug but not tight. DO NOT INDEX TURRETWITH THESE LOOSE!! then tap the turret the direction you need off a tool holder and a dead blow hammer. Or use a brass punch. Then once you get it where you need it retighten that bolt pattern you loosened up. Center of tool holder should be zero on machine position. To re-set this. Set PWE to 1, look for parameter 1815.4 under "x-axis APZ" should be a "1". Change to "0" Then the machine will need to be powered off and on again. On power up you will get a apz alarm... its ok. Sweep the tool holder in again and then jog the x axis to the home position. and set that parameter back to a "1" again. Then cycle power and you should be good.
