Gene,
This probably isn't exactly the one you're looking for, but
it's considerably cheaper than $90. You do have to install a 5k
pot. They work very similar to the mini-lathe motor controllers in
that you have to ramp up the speed. I think they're based on the
controls for
Thanks Dale, A good idea but not workable in my case I'm afraid. Have
you tried pouring hot metal into a 0.5mm hole? Almost all the work I do
is on antique watches and marine chronometers and so the screw sizes I
deal with are from about 0.3mm up to 3mm. That is why I resort to
cocktail sticks

Hi Ian,
My understanding of the threading module is simply that is
coordinates motion between the spindle and
the X and does not need to control the speed of the spindle. Hence an
AC motor will serve.
It is my impression that you need much higher rpm on the spindle than
you can get with a

Greetings;
I've been to the wiki, and searched for e-stop, but there isn't very much
there except the MAZAK setup as text. I read schematics better.
Does anyone have a suitable schematic link I could adapt for use with this
xylotex 4 axis and Steves (PMDX) spindle controller?
I still have
Hi all
[I originally posted this at CNCZone, not realising that this list is

Apologies in advance therefore for any breach of propriety.]
I'm looking for some guidance about the charge-pump set-up in EMC. I
have found in the set-up docs how to assign a parallel port
Here is the relevant hal stuff for one of my setups. This is from
a .hal file for that machine.

Gentlemen,
Another project, another question.
I bought an old Sheffield Cordax manual CMM. This is supposed to
replace a surface plate and height gages. Our inspectors have
experience with manual CMM's. They are looking forward to using it
instead of height gages.
This was supposed to
I am certainly not an expert but have read quite a bit-others can correct me
hmm . From what I remember Heidenhain takes those four signals and superimposes
them into two signals. This creates a sin wave on each wire pair (of two
pairs) that cross zero. Then you can get a black box that
14 matches
