I do have another okuma question though. It pertains to a .sdf program extension. We have a 2 pallet hmc, when I run the same program on both pallets the machine will automatically rotate the pallets and start the operation, if I'm running two different programs it will automatically rotate but will not automatically start running the program. On my MA-40ha machines I use the sp-select function to find the .sdf program on my newer MA-400 spacecenter I can not find the sp-select function to load the .sdf program. In the edit screen I can find the .sdf program and edit it but cannot find it under the load main program screen. What am I missing to make this .sdf program work with two different programs?
