Ken I have a LT02 and that is switched on by a just about any infrared
pulse waveform and the return appears to be 115k baud optical, I am
building my own OMM with an arduino MI as soon as I get around to it,
had to get a fast opto diode an opto transistor I first obtained was
deaf and too slow

Don't rush into buying one. I set up a search on eBay

Do they list the entire spindle? It would save some machining.

I haven't managed to find an OMM + MI7 for an affordable price (this is only
a hobby). My current plan (hope) is to build the equivalent of an OMM. I
assume that what is required is something like a Vishay TEMD1000 photodiode
feeding a TIA and then follow with an Arduino or something similar to

Looking at the spec and the screws holding the rotary
Do you have an OMI, or are you trying to connect directly with your own?

Here is a way to make a nose with "embedded" screw heads.

You can see inside with the "explode" slider.
I might even make mine this way, it will

Pity there is no picture to be sure that it is the right part.

I have a Grizzly G0709 lathe and they offer these as spare parts.

Hello Everybody,
what Sebastian so eloquently described is what I originally meant,
however what the other people that replied added is also relevant I
think. The linear velocity phase results in a constant acceleration that
will have a Dirac delta function in its first order derivative, and
Robust control work so well research in control theory has really dried,
then can you tell me how to make robust control so we could change from PID
with feed forward to robust control?
