Got him already. Working on it.<G> For my machine users... Won't be

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.
