Re: [Emc-users] Possible Error in Linuxcnc.org html docs for 2.7

I got busy and missed the original email but saw this one so the docs 
are correct now...

I agree, and actually you can use an absolute encoder or a resolver
too (In fact I _do_ use a  resolver)

I suspect that, if you wanted to badly enough, you could orient a
spindle to hall sensors.

I'll 2nd that Greg. A big tip of the hat, as deep a bow as my back can 
manage without something to hang onto, and a standing offer of a hand 
cooler (or 2) to any of the docs people that manage to find my place.

You ARE appreciated, we (me included) just don't seem to say thanks often 
enough.

Thank you all.

Cheers, Gene Heskett

[Emc-users] Possible Error in Linuxcnc.org html docs for 2.7

[Greg Bentzinger]

Looking at the description of "M19" it states that it requires a differential 
encoder with index to function.

I believe it should be (any) quadrature encoder with index. (differential being 
great for noise immunity but not an actual requirement.)

Not trying to be picky, but the docs are how people learn, best to provide the 
most accurate info possible.

And to those who maintain said Docs, Thanks for doing an endless job.

Greg
