Fixture Offsets

If you have multiple fixtures on your machine the G54-59.3 coordinate systems are what you use to set these up. Lets set up two fixtures using G54 and G55 coordinate systems. Use an edge finder or other suitable device for locating the X0 and Y0 of each fixture.

Setting up Fixture Locations

  1. Go to the DRO tab and verify that no G92 offsets are in effect.

  2. Jog to the fixture that will use the G54 coordinate system and find the X edge.

  3. Make sure the X axis is the selected axis on the Manual Control tab.

  4. Touch off and select the P1 G54 from the Coordinate System.

  5. Enter in 1/2 of the edge finder.

    1. If your on the left side (the minus side) of the fixtures zero point then enter in a negative number.

    2. If your on the right side (the plus side) of the fixtures zero point then enter in a positive number.

  6. Jog to the Y edge of the fixture.

  7. Make sure the Y axis is the selected axis on the Manual Control tab.

  8. Touch off and select the P1 G54 from the Coordinate System.

  9. Enter in 1/2 of the edge finder.

    1. If your on the front side (the minus side) of the fixtures zero point then enter in a negative number.

    2. If your on the back side (the plus side) of the fixtures zero point then enter in a positive number.

Follow the above procedure for each fixture and us a different coordinate system for each fixture. Now you can execute the same G code for each fixture and simply change the coordinate system to switch between fixtures.
