I agree with Marv on the randomness of the layout. Wondering if there is not some kind of vision system in the print head...the cables on the right may be part of that feed?? It appears to me that each die face is printed complete before moving at what seems to be a random jump to an adjacent die or to another area. I get the path problem but from a manufacturing standpoint I don't understand why there are no clamps unless a vacuum is used. Also note at :06 the front row seems offset a bit from the subsequent rows. I would think a loaded rack would need at least 5 sort/print passes plus drying time.

Even with modern AI it takes a while to optimize a path for even a salesman.

Good thread, Thanks!
