Got him already. Working on it.<G> For my machine users... Won't be
free, but not too expensive either.

No need to "remember", just use incremental motion (G91) for the
syringe leadscrew.

I don't agree. You need to have the ability to adjust the size
of "dot". Once adjusted for a given machine and SMD footprint, it
wouldn't need modifying "on the fly"... You're making it harder than
it is...

Most commercial solder paste dispensers use the leadscrew model. The
EFD unit has a remote leadscrew coupled to an axial plunger cable,
like a lawn mower, or an aircraft throttle.
