Homebrew PCBs

Hi Steve,
I looked at fireballcnc, but it seems that there is no machine with even
close parameters to the necessary for PCB. For DIY purposes they may be
sufficient, but for fine operations – no! And… something else
– they does not have software – which is not at all a small
problem, especially for CNC PCB machine!
And a Dremel for spindle is not good enough.
I studied the question and reached the conclusion that a good CNC
machine must obligatory have depth limiter and a foot. The real Z axis
gives much other advantages (in front of pseudo Z axis in the cheaper
LPKF), but without depth limiter there is no way to use V instruments
for isolation (5-8 mils)!
I like very much the Z axis of Accurate 360:
(www.accuratecnc.com/Pictures/Small/A360_z-axis.jpg

looks solidly made, exactly for fine operations like PCB.
