I restored the indentation just to keep me happy, and copy/pasted the
machine control buttons, the stuff between the leds and the align

I'm shopping for some linear/glass scales for a custom industrial machine.
I only need to read 8" of travel.
Does anyone know of an economical solution.I'd like full quad
outputs - ttl would be ideal.
I don't need super resolution or accuracy. .001" would be sufficient.
Thanks,

Yes, you are right. That would be a good solution.
I may just want to clarify... The whole discussion is not about the
correct
The other approach to take is to forget about home switches and do a
touch off on the work or the stops by using a probe.
Mount the probe in in the spindle and touch off on the stops or the
workpiece to obtain a zero position.
There are some relatively inexpensive probes for sale.
