I looked at those motors once, but was stumped with finding a suitable power
supply. Where do you find a 12v 125A power supply? (or whatever it works
out to be)

Hello,
I need this configuration to apply the PWM output for output to m5i20
net spindle-cmd = motion.spindle-speed-out = pwmgen.0.value
net yenable = pwmgen.0.enable
net spindle-pwm = pwmgen.0.pwm
setp pwmgen.0.pwm-freq 50.0
setp pwmgen.0.scale 82
setp pwmgen.0.min-dc 0.05
Hello again,
first off thank to all the suggestions about the encoders I was asking
about. I think I'm just gonna go with the requirement of zero'ing position
prior to milling any part.
My new question has to do with the servo drive's input. When it should be
at 0v, the input to the drive sits
Gentle persons:
I've admired the brushless DC motors used in radio-controlled aircraft
for some time. Their power and torque per size and weight
characteristics are mindboggling (and a testament to the evolution of
magnetic material in the last ten years) but I worry about their ability

Greetings all;
I find that I can get brass tubing in pretty small sizes, like 1/16 OD,
usually sized to be a slip fit in the next larger size, so this makes it easy
to solder up a small nozzle, with the far end built up to 1/4 for attaching
the air supply.
Now, I'm wondering if there is a

Here is how I did it. I took a short piece of brass bar and drilled most
of the way through with a drill slightly bigger than the smallest tube I
could easily obtain. This creates the air jet. I then drilled the rest
of the way with a drill the same size as the tube. Next I drilled

If it's organic, it's bound to be Castor oil, an excellent lubricant.
Because it gums up over time, you could just let it go to drain.

Castor oil is a good guess but not the only one. It's fatty acids are a
couple of carbons longer than the average cooking oil and does seem to
survive well as a lube in model airplane engines. On the industrial
market it is about 30% more expensive than canola. If I wanted to go
cheap I'd simply

. Can I successfully use a p-port on a laptop like
a new Dell Latitude E5400 that has an E Legacy Extender to add a
parallel port?
I don't know for sure, but the P-Port in the docking station of my
Latitude (D630) is a proper pin-addressable port.

Hi Gene,
almost exactly the same as an air brush gun, where the liquid
comes out of the center. So that center tube feeding in the oil is
surrounded by by the air exiting through the gap between the OD of that tube
and the drilled holes walls.
Yup. The tricky bit is finding the right

Very likely.
There is no work-around because it's a hardware/BIOS issue, not
software.

I think there are so many CAD CAM on market that it is not easy to choose
one.
Start with CATIA $ 21 000, MasterCam $ 15 000 to CAD CAM that cost few

I think that future for CAD CAM is in Cloud Computing.
Goggle and Microsoft try to bring it up.
