I am dropping items into a tray and want to do this in a specific sequence. How would I include this in my program. Here is my current program. I am also having issues where my action, approach, and exit are still showing yellow as if they are undefined 

The program locks ok.

Maybe you could remove the yellow color by initialling those positions in the before start ?

Why don t you use the UR pallet node ? That would ease the programming.

Figured it out. The Palletizing program keeps running to points that are not the ones being called and has several bugs
