I am thinking about making a turner's cube on a mill.
It is an easy task, but for elegance, I would really like to write a
turner's cube subroutine that would call itself recursively.

O call [...]
O endif

Can I do that?

Hello Andy,
it's just the same here, if you separate the usual three phase supply
into three separate 230 V-systems, each defined to ground. I was talking
about a, say, small household, where only one of these phases is
available. Other households in the same building may have others of the

Kirk,
"Neutral" is not to be considered. You have two wires coming from the
supplier. Adding a capacitor makes three of them. The two mains lines
are 180 degrees apart by definition. The capacitor makes a third phase
90 degrees between them. Connect your motor, and it will be running,

If you are using comp, then you can use the variable fperiod. (which

Gentlemen,
using a "phase pusher" capacitor is a cheap and common workaround when a
three phase supply isn't available. I have used this with a lathe for
some time, since a machine like this doesn't need its full power most of
the time and it always starts idling without load.
Ordinary three p

Yes, I tried that a couple of times, but mostly I have been trying to
get back to the terminal from the halcmd: prompt, which needs to happen

I do the same for the headstock lubrication pump and spindle motor

tried a bunch of different values until I had the minimum running

Hi
I found very interesting software
http://www.intact-solutions.com/technology.php
It is about Finite elements that can be very important when design large
tool, fixture and teen wall part.
To manufacture -cut very complex and big part it is not enough to have
good CAD/CAM and good CNC machine.
