hi guys, I want to use a turret held, tight fit 1 inch bar puller to pull bar in. My problem is if I program the chuck to open with g80, the control gives me a chuck error and program stops, it will not move z axis after g80 open jaws cmd. How do I disable this error so program will keep running, Also what is the gcode to make it go back to start of program, and repeat program? thanks in advance...
