I know there are many ways to make PCB's, but I am trying to figure
out how to make a auto etcher. The building part is easy. The
problem is where do you get the software and how does it work?
Currently im using old 5 gallon fish tank heater and air stone to
etch boards and is very time comsuming when make larger boards.
Thanks in advance for your time and advice.

Sorry for not clearifing what im looking for. I am talking about
machines that take image from a computer and tranfers it on to the
PCBs,kinda like a computer controled dremel tool.
