Bacaklı dizgi4 is not a waiting area in real life. I just placed it to control the movements of solder2 and solder1. But the problem is that the simulation sees bacaklı dizgi4 as a waiting area and processes the product by taking a new card to preheat. In real life, the card that is finished preheating remains in the machine and a new card is not processed in preheating until the card is transferred to solder1. What I want is to solve this not with code but with trigger properties. Can you help? @Felix Möhlmann
