Subject: Re: [Homebrew_PCBs] Re: SolderPaste dispenser and Pick and Place.

I just went to the Cadsoft website under ulp I still don't see the
file with the name smd-coordinate.ulp. You are probably right there is
better way to do it. If I ever find this ulp I will give it to Steve
to try. At the time that we did it there was nothing we found that was
available. You need 2 different reference points the center of the
part for pick and place and the center of each pad for solder paste.
One axis sorting does not give you the optimal g-code with the fewest
moves. Pads right next to the other pad will be skipped and come back
to latter. An intelligent sort that can handle 2 axises at the same
time is what is needed.
