It's not a miracle, but it is not a true encoder. As in it's not physically "counting" pulses, it's creating them. If I am understanding the way it functions. It it better than a single magnet on a shaft, but it's not truly positional though 360° of rotation.
Encoders - need REALLY basic info (resolved)

Re: Encoders - need REALLY basic info
I found this yesterday:
http://www.ecomorder.com/techref/ecomprice.asp?p=416083
It's a 4000 count/rev encoder using a single magnet. I emailed the guy who makes them and am still a little confused but, from what I'm understanding, it is actually reading 4000 positions per revolution of the shaft the magnet is attached to. The magnet would attach to the end of the motor shaft (imagine just letting it stick to the end of the motor's steel shaft) and the sensor goes above it. The magnet is not attached to a spinning disk or anything like that. The magnet poles are oriented differently from a "normal" magnet and the sensor is reading the changes in magnetic field as the magnet spins.
The only thing is the encoder outputs aren't correct for what Acorn needs. So, I think you can use one of these:
https://cnc4pc.com/c72-differential-line-driver.html
I believe it will convert the above encoder's "simple" outputs to the proper outputs required by Acorn.
Once I get caught up with work and other necessities (and also figure out my mill setup), I will have to try this on the lathe. I saw Keith's post re. lathe software so I'll go get my wallet now.
