But it would not be impossible to create a different interpreter and motion controller for pick-and-place which made re-picks and re-starts easier. The situation is much simpler than a G-code interpreter, there is no need for coordinated motion, for example. Really, the coordinated motion is such a small, lower-level detail. I might mention my Philips CSM84 uses coordinated motion, too. Really, you'd want to split part pick-up from part placement, and have them handled by two different databases. That's the way my CSM works. All the feeders are in one list, with location, pick-up angle, how much to advance the tape, etc. and a whole bunch more info. The machines with vision have another database for the part outline data. Since this guy's machine has vision, he needs to locate the centroid of the part, generate G-code to pick it up from the corrected location, then get the centroid with the bottom camera, generate G-code to place the part at the corrected location and rotation on the board. So, although the program seems to use G-code, I don't think it is one big linear program that is run, it must be spoon-fed to the interpreter a couple blocks at a time after the vision system has applied the corrections to the coordinated. I can't see where the upward-looking camera is or where it takes the part for alignment inspection, so he may only have a downward-looking camera, which doesn't make much sense. Maybe he only uses the upward-looking camera for high-density parts.

Re: [Emc-users] Linuxcnc 5 axis coolness
This isn't quite at the same level, but if it hasn't been mentioned before, here's a pick and place machine running on LinuxCNC http://blog.makezine.com/2012/05/20/diy-pick-and-place/ I'm not sure how well it handles errors, missed pick-ups, etc. and there are a lot of those in general PP operation.

Interesting. I can't help but cringe when I see precision applications built with plywood and mdf though. I'd like to see a closer view of his tape handling. Speaking of errors, I see a couple on his Axis window :-). Looks like a good effort though.

Speaking of errors, I see a couple on his Axis window :-). Looks like a good effort though. I'd be interested in more details on it. There are a number of YouTube videos of this machine. He uses a rubber pad next to the nozzle to advance the tape by friction. Something like a weight applies tension on the cover tape (not shown in videos.) Then, the vision system identifies the first part on the tape so the nozzle can pick it up. When the pad is advancing the tape, the nozzle drops into the space between tapes. Yes, funny he'd leave those big red errors on the screen for a video! He sells a kit for this machine on his web site. I'd really be interested in how he deals with error handling. I get a fair number of mis-picks on my $100K Philips CSM84. It has 3 different nozzles in 3 heads with alignment jaws currently on two of those, and no vision. Maybe with the vision there are a lot fewer errors. But, the pain with restarting a program on LinuxCNC now would make a LinuxCNC PP a real nightmare. The CSM84 recovers automatically from up to 4 pickup errors before calling for help. There are certain parts that give me fits due to variations in cover tape adhesion, tape thickness and funny shaped parts that don't pick up or align properly on the jaws. Also, my CSM84 runs at about 3600 PPH on most parts, only slowing down when it has to take the large chips over to the mechanical alignment station. I don't know what the speed of this machine is, but it looks like a bit better than 600 PPH. I could live with one that slow, but I wouldn't be happy.
