I will try that with my CNC. The resolution is just right for that. But 
the speed can be to low. But if head pass the test with CNC then I can 
make another fast XY machine.
About drop size I have no clue what I can expect. I can make nozzle very 
thin but I think for the solder resist I need the biger nozle as I need 
thick layer. And If think work I can build another 7 nozles and have 8 
nozles as in old dot matrix day's.

Stil need a lot of experiment here. I just think how to observe drop or 
to capture it? Is it drop? Is it stream? Maybe some strobo light 
sinchronised with firing pulses?
My interest right now is to make printer able to print stop mask layer 
on pcb (green stuf). After that I go finer. And if works then this can 
be just great for flip "n" print idea...

Slavko.

now I gona to check that links....
