1000 words have been added :-) I updated the wiki page
(http://wiki.linuxcnc.org/cgi-bin/wiki.pl?GantryPlasmaMachine) with a system
wiring schematic. There is a pdf version and an Eagle (v6.1.0 - won't open in
version 5) .sch file. Follow toc link "2.4 Wiring Diagram". I also added our
Mesa 7i43 (400k version) firmware files.
The only thing missing from the schematic (I believe) is a small circuit that
provides noise filtering on the step/dir, and IO lines between the Granites and
Mesa cards. As soon as I round up my notes on that I will add it.
