Re: [Emc-users] Mill Head Travel.

[Stuart Stevenson]

I use a process similar to Jon Elson's.
I use a lathe face plate and 3 adjustable supports.
With an indicator in the spindle I drive X and Y to dial the surface of the
face plate parallel to the XY plane.
I then go to the center of the face plate and sweep the face plate
adjusting A and B as necessary.

[Emc-users] Encoders

[jeremy youngs]

Hi all. These ametek motors have undefined encoders on them. One is just an
empty 4 pin. The other has a flat 4 pin ribbon. I'm awaiting my 7i42 . The
flat ribbon is marked with a hot lead. I also have a 5v current limited
supply on order. I'm thinking set voltage low and shuffle ground until I
find the 2 pins that provide an output to my frequency meter , then I will
know which ones are my a and b . Once I get the 7i42 I will then be able to
use Hal to find their count me any words of advice or am I solid on this .
Thanks

It's not a ROM, it's actually an 8-bit microcontroller.

And the other side seems to feature a quad comparator, a pair of dual
DACs and some op-amps.

It all seems a bit over-the-top
