Bill,

I learned the hard way that if you are going to do Flip Ops (as opposed to individual parts) you must set up the Flip Ops First parameters properly. You will notice there is an option to Trim Sheet. CHECK THIS BOX! Then select the method you want to trim the sheet so that it will register correctly when you turn it over. I use the Pin Area Only option and have 2 X-Axis pins set up on my machine to register the material. I don't have a pin on the Y-Axis - I use a v-groove in the spoil board. Even though you are not forced to select the Trim Sheet, you need to do this otherwise your parts won't register properly when you flip the sheet. Don't ask how I know this....
