Hi,

I would like to develop new CNC controller based on the PC. Using
Windows seems ok, Being more familiar with Windows than Linux. I figure
these new PCs run so fast that they must be able to stay ahead of a
mechanical cutting device.

Does anyone out there know how to build a kernal program that will stay
in memory, be started at the 1200000 interrupt rate, and communicate
directly with the printer port, and with my controller via a queue of
data?

I am driving the parallel port through a XYLOTEX into an tabletop mill
(as of yesterday), but there is no kind of timing being attempted.




There are already a number of PC based CNC controllers out there being
manufactured by companies like NUM, Siemens, and others. Also, I believe I have
seen software out there already that runs on Windows 2000 and/or XP that can
be purchased quite reasonably. Since I work mostly with the industrial
machinery, I deal with NUM, Fanuc, Siemens, etc. but I am sure I have seen some
software for a pretty low cost that will operate on a Windows OS. You don't
want to be using Win 95 or Win 98 of course but Win 2000 pro and Win XP or XP
pro seem to work just fine. If I run across the software again online I will
try to remember and send you a link.
