0.01mm is about the resolution of my stepping setup. Mechanically a C7 screw and nut is 0.05mm or better.
I think these sensors are a good match for my system. Anything more would have been overkill but I can see why you'd like better if your doing the kind of precision work that absolutely requires it to be dead on.

The other issue you can get with these that you don't get with a 3D printer is keeping then clear of swarf? you would need to shield them very well
If the nagging gets really bad......Get a bigger shed:naughty:

That's because the sensors in that diagram have a NO output.

Ah I didn't realise these where NC switches. . . Makes sense now.!! . . . Really should start reading the threads more often.!
(To be honest didn't even knew Proximity switches add NC - NO option never used them or thought about it. Thought they just sensed magnetic fields but on reflection it's obvious it's just an electrical circuit so could have and would need to both options to work has switches. . . Doh.!!)

I thought I'd bounce this thread as I have a question related to the ALM output from a Leadshine drive (EM806, which is pretty much an upgraded AM882).
Is it safe to wire the ALM straight to a PIC pin, or should I use another (opto) transistor in the middle somewhere to isolate the two?
Regards,
T.

Lol, I'm not keen on blowing anything up, thus the question :D
