Now _this_ sounds like serious fun... enough to bother going to Mesa for
a PLUG meeting, even.

I have the low-end Light Machines milling machine
http://www.lightmachines.com/productcenter/spectralight-0200-page1.html
(got it used at a hamfest, good deal too)
but it didn't come with the controller box. I want to build one of
those parallel-port stepper drivers for it, but it'll be my first
project of that sort. Do you happen to know where I could get a kit
for one, beefy enough to run the motors? The kits I've seen top out
at 1 or 1.25 amps, and I think these motors might require more like 2 amps.
And, I haven't figured out which kind of steppers these are yet, bipolar
or unipolar.

I would want to run it with Linux, of course, and I think I stumbled
across this NIST software when I was looking for such things... made
a Netscape bookmark... and now Netscape won't run for me anymore. Why
can't all the browser-folks just agree on some way to store bookmarks
on a server... they don't belong on the client anyway, because doesn't
everyone browse the web from more than one place? Speaking of which...
setting up such a solution would be another very good PLUG presentation,
if it's possible.
