[time-nuts] OT stuffing boards: was GPS interface/prototyping board

[Chris Albertson]

OpenPNP has a set of drivers for each class of PNP machine.  One of the
drivers outputs LinuxCNC g-code,  They already have other drivers for other
kinds of machines, maybe 8 or 10 in total.

Yes you could translate centroid files to G-code but that is exactly what
openPNP does.  It does a little more because it figures out where the parts
and PCB are on the table using vision.  openPNP can pick up loose parts and
place them on a PCB that is dropped by hand at a random place on the work
table.  Open PNP will locate marks on the PCB.  It looks good because you
don't need build jigs to exactly position either the parts or the board.

The way your software might fit into this is to make a "universal driver".
Your driver would have to provide the standard API to openPNP and then
would output whatever it takes to control one the the 80+ machines you know
how to control.   But LinuxCNC does this too.  I reads up G-code then
drives almost any machine

OpenPNP does need a centroid file.  these can be CSV files or there are a
file CAD filers it can read, one of them is Eagle and some others
