you need to connect your parallel port input (I assume that you are using the
parallel port) to
halui.program.run.true. See the basic hal section of the integrators manual for
the basics of
hal. You can test your setup with a pyvcp button.

Is that a VIA video system, too? If so, it may not be compatible with
real time. Or, it may work a
lot better if you use a different driver, perhaps a generic VGA driver.

Gene,
I think your brain's working too hard!! You probably won't
have much success with Insulin needles as the length of thin
tube will act as a brake on the oil. One place you can find

It rather depends on if you run out of computer speed or motor speed
first. If you can easily drive the motors faster than they can move
the machine, then more microsteps can give you a bit more res

I will try inverting the step signal.

There seems to be plenty of pressure to make it flow.

That is also a thought, use Ian's idea to swage it down to nearly zip, use
the needles piercing point to bore it to fit the needle, and then glue the

Just get it hot and keep it that way for a while. There is no phase
transition to worry about with brass.

I would be concerned about having a very fine needle sticking out. It
would be very vulnerable. I have no problems with a piece of 1/16" OD
tube and a needle valve. You are going to need a needle valve anyway
because some jobs need more oil than others.

As far as I know you don't have to hold it hot for very long. Get it
red, quench and job done. Quenching in battery acid helps remove the
black oxide but beware of the fumes.

If you know what you need in a power supply, old stereo amps are lying
around unused these days since everybody is switching to 5.5 channel
home theater or better. Each half of a split supply for a 30 watt per
