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.

Yes, you are right. That would be a good solution.
I may just want to clarify... The whole discussion is not about the

OK could be the optical switch sonly used for self-calibration when the
printer is first powered up. Still the little things are very accurate. I
bought some a while back, I think a bag of them for $5 on eBay.
Does the printer need to do a SLOW home one each line? I thought the

I understand your situation.
In light of what you said you might want to go with Prox switches and
forget about mechanical microswitches.
My reason is this: Small cheap mechanical microswitches are very easy
to break and hard to mount, protect and adjust.
Prox switches are just the opposite.

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,
