Homebrew PCBs

I'm of the opinion that the nuts and bolts of your machinery is as much a 
part of making PCBs as is a bubbler for the etch tank, or a high speed drill 
press. It is specialized, and has opportunities and needs not common for 
general purpose CNC machines. I can think of no better place than here for 
the discussion.

Linear slides and precision ballscrews for small boards and very light 
mechanical loads are relatively inexpensive. In whole and in sum, the cost 
and complexity are manageable for many of us, and the capabilities of very 
great interest. I realize that documenting something of this scope is a 
significant commitment. If you can find the time to share the details, I 
think you'll find a receptive and eager audience. However, if you would 
still like, I am happy to respect your wishes and keep the conversation 
off-line.

But first a question about your process. Did I understand you correctly, 
that you etch directly using the ink as the resist?

Regards,
Mike.

There is no web at least I know which explains operation of Epson heads.
I learned it by reading Epson patents and by measuring actual printer.
If you really interested with that and want to design yourself I can help 
you,
but implementation details are most probably off topic for this group and we 
need to contact offline.
Y-axis has very precise servo motor coupled with 10000 pulses (in quadrature 
decoding).
I have also precision linear slides on Y-axis.
