And while I am obviously a fan of LinuxCNC, thats not saying there aren't other solutions if you are more familiar with Mach3. To quote a very old saw, you went to the races and ran what you brung. :) > As far as I can tell the best selective soldering machines use a > solder fountain.

How is that determined? Perhaps by the amount of solder that has fed once it has touched the work and stopped till some melts? A smaller fixed amount, perhaps with a second or so longer dwell before the iron is withdrawn to allow better penetration into the gap between pin and plated thru hole? However I'd have no clue how to go about determining that exactly .075" of solder has been melted. Solving that by something other than elapsed dwell time would seem to be something that needed a good solution. > > The reason for using a drill cycle was that I wanted to use the > excellon drill file from the PCB CAD software as the starting point.

All my comments are based on having a hot soldering iron in one hand since I was about 14 years old. And I had to learn the military way in '60 when I got hired on as a field checkout tech while building some of the first Titan ICBM's. They don't like solder, claiming if a wire wrapped around a turret post was more than 50% covered, that made it too hard to grab the end and unwind it, cold. Fluxes have come a long ways too since those days, unfortunately the hands are not as steady as they once were. So its safe to say that I am not the man I once was, even once. :) > Cheers, > > Peter > > On 10/05/2015 12:48 AM, Gene Heskett wrote: > > On Saturday 09 May 2015 05:43:10 Peter Homann wrote: > >> Hi, > >> > >> This is the soldering robot I have.
