A phantom die stroke is a die stroke where the die cycles but does not fire the press. Die Accelerators configured with Multiple Presses on the Die could exhibit phantom die strokes coinciding with other open loop press targets.

Prior to recent changes to the XL244CL the only time this bug would be exhibited is if the controller had a also had a part printer installed.

There was a bug where the open loop press targets would also be added to the master press queue for Die1 due to a missing test in the code. The master press controls the die stroke for any slave presses on the die that have targets at the same time. If the master press does not have a target its queue target disables the master press from firing.

The bug has been fixed and the phantom die strokes no longer occur.
