Put the pcb, feeder pickup, and camera at the same z height so that you only have to z retract a few mm between movements. You can also put the feeders closer to the camera to get your speed up. Another idea would be to put the camera on the moving head pointed downwards at a slight angle to the tip, you would have to un-skew the camera output but could do the camera work while it's moving to get even higher speeds.
Thanks for sharing the ideas, optimizing the layout will help for sure. Tilting the top camera is an interesting idea, not sure if that will affect accuracy, but worth a try.
You know you can change the focus of the cameras to suit your working distances? It usually requires breaking of the glue drop they place on the threads but once free they are easily adjusted. This is assuming you are using fixed focus cameras (because focus is so poor) and it is not practical with autofocus on CV systems as it changes the aspects of image.
Thought I'd chime in that I hope you are doing well and I've truly enjoyed following along with the project.
Thanks, I am doing well, actually I am working on prototying the next machine, which takes some time, will update soon!
You're an incredibly smart engineer
Thanks!
This is looking awesome, the speed is really nice. I cannot remember are you plan to add solder paste using the gantry?
Thanks, for the solder paste, I thought about it at some point, but openpnp doesn't support it any more. And I am ok with using stencil now.
Nice job!

Indeed the focus need to be adjusted better, thanks for pointing out!
