    Unhappy fixture offsets

    I've been trying for a couple of days to get the program below to run multiple offsets.
    X0.Y0.
    X5.Y0.
    X10.Y0.
    The machine is a Fadal4020 with CNC88 controller, format 2. Iv've tried using M98-99, E1-3, G54-56, and I just can't seem to figure out the proper coding to make any of it work. I would be most grateful if someone would either e-mail me a program that works in this manner, or edit the program below, so that I would have an example to go by.
    Thanks,
    Richard

    Here is an example, same control, Format 2. Running 12 parts on a fixture, 6 on the front, 6 on the rear, with a coordinate rotation. The parts are 5 1/4" wide, spaced about 6 1/4" apart. A bit lengthy, but a good example. I have a pin that stays on the table for location so fixture offsets E10-E21 are permanently set in the offset table. See the attachment for the entire program with all the sub program calls.
