my hitachi mill uses a taper lock type system that works kindof like
compression fittings for steel tubing. the end pieces squeeze on little
rings that apparently do the holding.

I have been using several Wafer LX 800 for embedded development work
over the course of the last year, they have dual ethernet, compact flash
slot on the back, use regular laptop ram and have both parallel and gpio
for ouput. They are a bit more expensive than basic types but i'm sure
they can be

HI All, I am a retired machinist and I have a little experience
running and programing CNC. I have a drill press that with a X, Y axis
milling vice on it. I do a little milling on little home shop
projects. I have morris taper endmill attachments and it don't do to
bad . I would like to

For a parallel port replacement Ethernet, maybe a thing to

Thanks Ray that was pretty much what I was hoping to hear. I'll be
reading everything I can find on line and then. I'll be back asking
questions when I know enough to ask a decent question.

But, the Ethernet driver has to be running as a process under
the real time system.

Probably get labeled as a heretic but for a real simple low preformance
system where you are not trying to run a 3 axis tool path at a constant
velocity you may want to start with something like TurboCNC running on plan
old DOS. Unless you just want to have a Linix system.
You can always
What is the best way to drive a 4hp, 90VDC, 40A spindle motor on a
Hardinge CHNC? Some of the large DC motors I have seen, look like
universal motors which would operate on AC or DC. Does anyone know if
the CHNC spindle motor could work on AC? I'm thinking, a few dimmer
switches in parallel and a

Thanks for the help on my zero motiion homing problem. I am using
Jeff's workaround and all is working better than expected.
My current project is converting a Derbyshire watchmaker's lathe to
CNC by using a couple of tiny (1 inch diameter by 4 inch long brush
servos on the cross slide (x/y)

I recently saw a really nice discussion of how to calculate base
period, servo period, task period, etc. based on cpu speed and
maximum
I've got several of these motors out in the garage and I don't think any
of them would handle AC. The ones I've got are real DC motors with
quite a few windings and a massive commutator.
There were at least two DC motors used in these, rated at 3 hp and 5 hp
nominal. If you look at the drive

That's not the one I remember but it looks like it might be even better.
I just spent the last 3 hours thinking I was searching the wiki for
stuff like this and basically came up with nothing.
I guess I don't understand the search methodology. How does one go
about finding stuff in the
