thanks Dave.....
i don't like the "couple of weeks" part,
an the "fast programmer".
i could of course edit the librarys so that there is a short line on the
place
where the paste has to go. one could use multiple lines, and vary the
lengt to change amount.
I still don't get the part where it moved from a 2d excellon drill file or
gerber file
to a 3d cnc file, where and how do i add the drill depth, feed speed, etc?
Is there a really simple solution to modify these "z axis" action to get a
dispenser
to "mill the paste above the pad"?
I mean imagine you have a 2d drawing of a part you want to mill, how do
you add the
z axis? how do you tell how fast the dispenser goes down, and how far it
moves?
Maybe the "pump paste now" could be hardware engaged - whenever the nozzle
is down fire up..
one could use adjustable delays and "suck back" as soon as the nozzle is
raised.
