I read the data sheet and found this quote:
" If the direction of rotation is reversed, so that the gear rotates
from the pin 4 side to the pin 1 side, then the output polarity
inverts."
Thanks for pointing out this device. It is NOT a simple Hall effect
sensor. There are two hall effect sensor

a friend owns this company, i make nothing off its sale
but i think i should let people know about it as a resource
its designed for spindle speed control ( using little space )
and he has been successful selling it to oems in Taiwan

I have added another video to the Learning LinuxCNC Youtube channel.
Feel free to view it at your convenience. I should have another couple
videos posted in the next week or two.

Yes; it is only the ageing capacitors in some of the equipment from that era
that lets the kit down.
I never used Tek equipment, but did use the early Data General SuperNova in the
early 70s, then the DEC stuff, all of which was very well made. I smile when
folk say "Why does such-and-such a com

Can anyone recommend a group that covers general Linux discussions.
Distro specific is OK - Ubuntu, Debian, etc

So - maybe it really doesn't matter.. It should be the same edge for
threading/rigid tapping...

Ideas:
1) How close to the motor is the sensor. The motor might have a large
external magnetic field.
2) I wonder if the shaft is magnetized while is spinning? Is this reversed
if the shaft spins the other way?
3) Is the sensor powered from a reliable DC supply that is in no way
connected or

We purchased some gear tooth sensors in hopes of using one of the gears in the
K&T for a spindle encoder. Well - we ended up putting a shaft encoder in the
gearbox.

Mark,
This is completely off topic but I thought you might be interested.
I have a Tek 511-AD (Tek's first model) vintage somewhere around 1950
or 51 that I managed to rescue from an outside pile of electrical
scrap at McConnel AFB in Wichita Ks in 1971.
It had been laying outside in the rain an

No, it isn't. But you can end up increasing the tool length offset by
a sequence of tool-touch-off and work-touch-off actions.
I think you need to sit back and clarify in your head
