Hello all,
I am having trouble figuring out why there is a disconnect between some parallel loops in my main VI. The general idea is that the feeding loops are state machines that will snap a photo, run a detection subvi and overlay vi, and send coordinates to another state machine for a robotic pickup via queue if there is a part detected, or run a partial/full feeding cycle dependent on if a partial had been run already or not. One of the feeding loops has two parts but I think that is negligible. The state machine that is responsible for part pick has a dequeue element in a while loop with a timeout that determines when a part is ready for pickup then goes through the pickup cycle.
The problem that I am running into is that the snapped image data will often not update and so the feeding cycle will send incorrect data to the pickup loop. I am unsure at which point in the feeding loop it is doing this because the buffer for the image gets copied onto by the snap and by the overlay subvi but neither can be skipped over in the loops. My instincts are telling me there is something about the properties of image buffers that I am not understanding and I am hoping someone would be able to help find what's wrong with my architecture. Thank you in advance.
I have attached the Main VI and SubVI's and I am using LabVIEW 2020.
