This issue is possible due to SCN 4655 - XL2CL; Position the Die early when delaying for a stationary shear or punch.

On the first part after a Queue clear, SCN 4655 can cause the die to rapidly pre-position itself for a stationary target that results in the die out running the leading edge of the material. When this happens, the material drops out of the die, which can cause a jam up when the material catches back up to the die.

The software was changed to test if the resulting die position places the die beyond the current location of the material leading edge. If it does, the pre-positioning is disabled and the die will wait for the material to stop before it is positioned for the stationary target.
