Hmm I worked it out, I don't really want to talk about it but I was trying to add outputs on pins that were already assigned to inputs, and strangely enough that didn't work...been a long weekend 

Thanks for the hint.
I will try to find out how these pins can be set TRUE when starting Linuxcnc.
Ok, the y-axis I do not need for the lathe, but X and Z. So some homework to do.

Thanks PCW

Thank you. The spindle is now working.

I really appreciate the help.

Thank you,

I've just created this topic:
"homing with Phase Z encoder on MESA 7i96s".

Thanks tuxcnc, ya I couldn't get it to work. The final IC's I used was a 26ls32 to single end the differational signal. Into a 74htc14 to boost the signal to 5v. And then into a uln2003 IC to pull down the 12v denford pulses. I was getting a lot of noise. I tried pulling up/down resistors and capacitors to try and negate it. But didnt work. These dm566 drivers seem to work fine with the ec500. I'll have to do some more testing.

I don't understand, I have to create another subject.

Linuxcnc servo cycle is not synchronized with the ethercat cycle. That adds an extra cycle delay.
