If this is for a touch probe or something of the sort, you only need
contact when the RPM < 500?
So, have a setup that if RPM is higher than 500, then a little solenoid
that tensions the braid (not spring, as you say) is released so there is no
tension on it.
You want a copper braid around the

I don't know what your spindle looks like, but to make an electrical
connection to it, you could use a piece of earth shield. The woven, braid
type that you find on better quality cables. These

Because of some odd goings on, like a 4mm end mill being drawn as if it
was a 3" face mill, I figured it was about time I added
RS274NGC_STARTUP_CODE= to the .ini file. But the docs are wrong,
recommending a bare G92 in the string shown when it likely ought to be a

Thinking about this as an electrical engineer, I'd say don't use DC.
DC current is as you say blocked by paint and oil films.Use AC.
I think a low radio frequency. Then the DC insulators would act like
capacitors and pass AC. even while blocking DC. To detect contact use
an AC voltage
Notice that now-days many of the "standard" SI units are named for
long-dead scientests
Volt,
Ampere,
Watt,

Hertz,

Pascal,
Celsus,
Kelvin,
Likely a lot more I can't remember. If you know a little history you
can remember them. I think that is why they use proper
I had a similar issue with a Shapeoko router.
There was no continuity from the spindle rotor to the rest of the assembly.
My solution was to mount a brush above the spindle motor shaft, to make
contact on the end of the shaft, then bring that back to the sense input.
And, yes, I brought a ground
Most of the pneumatic valves I use have a small actuator (coil) that opens
a small air passage to push the thimble within the valve body to the
requested position.
I recall that they are called "pilot valves".
So they use a very small amount of current to do a very big job.
I have used Parker
Greetings all;
I've just found that because everything it painted before assembly,
apparently including the inside of the spindle motor mount, that a

almost anything else on the 6040, and apparently even includes the

True ... but then a slug is lbf s^2 / ft, and I have enough trouble with
those venerable units without

We use hPa a lot at work. It annoys me.
In fact the same software in various places uses hPa, kPa, MPa, bar, psi and
inches of mercury!
