I agree, but the group where this would fit well,
http://groups.yahoo.com/group/CNC-PCB_Design/is not a very old list and does not have the quantity of list
members. But the idea is that it will become the list that covers
all the things specific to PCBs
There are lists that are more CNC oriented and I have found that many
newbies feel overwhelmed by them. Also, someone who wants to make a
PCB type machine is not as interested in how to re-build a Bridgeport
milling machine or making a plasma cutter.
But to be honest, the underlying principals both mechanical and
software are all the same.
