mesa 7i76 configuring a spindle encoder

OK Andy WE (you) are getting there axis now loads with no errors .
The file was generated by PnCConf for my lathe But I know there are bugs in PnCConf some have been sorted but have missed 2.7.4

Now I need to connect up the index A and B from the encoder. I will report back when I have done it

Thanks Andy can I trouble you with the setting up now.

I have connected the A, B and index to the 7i76 What do I have to set in the hal and ini file to make it work

What doesn't work as things are now?

Open a halmeter and look at motion.spindle-revs

If that increases by 1 for one rev of the spindle you are probably all set.

Ok no joy with motion.spindle-revs but the voltage on the index at the 7i76 pin TB3 13 changes from 5V to 0V when the chuck is rotated

edit I am using this as single ended input

What do the other two inputs do?

What is the ...enc0.position pin doing?

quote What is the ...enc0.position pin doing?

Can't seem to find that. Do you think I have it conned ok is there any thing to add in the ini file?
