PTF, feeder teach universal instruments

[loki42]

So I'm attempting to run feeder teach for my platform tray feeder... but I've got no idea what first point I should teach is... normal is the end pin of the feeder but this is for the ptf conveyor... so I've got no idea.  If I just teach each corner of the ptf slug it gives me a crazy value.  Is there a way to know where the reference fiducial / location is? Has anyone done this? My pick points are currently fine in the ptf but the head is missing the parts on the conveyor.

I've got access to the universal manuals / voyager but I haven't found a section that describes the feeder teach setup process, I can pick up the teach slug onto the conveyor and then get into feeder teach but if I teach the corners of the slug as the on screen prompts suggest (bottom left then top right in the feeder location to pick location action) it doesn't give me a valid offset. I have worked out a currently working solution, but I would be keen to know the correct way to do this. I laser cut a copy of the PTF teach slug and tray, then covered the laser cut copy of the teach slug in white board marker. I then ran the teach product in NPI mode with board transport turned off. I measured the offset from the ptf nozzle mark and the high force head nozzle mark, then adjusted the pick position so it picked in the centre.   So it works now but it's not as elegant as actually knowing how to do it correctly!
