Hello,

Im trying to add hall sensor to read spindle rpm. I do see Index window blink as I rotate spindle(port 3 input 4). But I cant get it to show rpm. Debounce set, relays output set, feedback in sync mode set. I send M3 command ("turn on spindle"), but still no effect.
So I see reaction on spindle rotation,but for some reason ,it doesnt calc RPM.

And advice, please?

Most Chinese boards only support a small number of Mach3 functions, so most likely, your board (or the plugin) does not support it.

Yes, but as I mentioned, I do see input on index port. I just missing something in mach3 setup to make it forward that data to rpm.

It may be that the response time of the Hall senor is far too slow? Rotate by hand: Ok, but spin: no joy.

Nope, no difference.
