At 3.716 minutes Cylinder1 enters PunchPress2 and the process finish event is scheduled for 13.77 minutes. The the cylinder is removed from the press before the process time is complete - which causes the error.

The reason is your detection of the punch press ProcessFinish is only looking at PunchPress1:

This needs to reference the relevant punch press for the item.

Try to fix this yourself (we encourage students to try and solve their problem themselves) and if you're still stuck post a comment below.

4.4 conveyor length 0.2.fsmThanks for you help. I fixed it already. And now I have another problem is AGV2 cannot move along the path between Station 4 complete queue and departure queue. Could I gain some advice from you?
