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,

Dan

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.
 

Hi Russell,
please add your config

Tengo que cambiar algo en pncconf

(my first post here)

I was given a Grizzly G1006 with a CNC kit.  The previous owner bought the mill new, and did the CNC conversion himself.  And he built the servo control box himself, including the power supply. And he built the pendant control box.  And he built the pendant.

Of course, I didn't know how any of this worked, but I knew I had all the cabling, and the computer.  So I plugged in the things that were obvious.  Then I had to reverse engineer the purpose of the cables that were not obvious. 

It was controlled from a 2003 era computer running Windows 10, and Mach 3.  The parallel port sent commands to a PMDX-122, which sent steps to three Geckodrive G320s. 

Anyway... I got it to move.

Now I'm converting it to LinuxCNC.

I have a Mesa 7i96s, that will be replacing the PMDX-122. I have a USB game controller that will be replacing the pendant.
I'm going to try to keep his original servo control box, with his bespoke power supply.

Ametek 38v 12A servo motors
USDigital encoders (250 step)
Mesa 7i96s Ethernet stepper controller
Geckodrive G320  x3

Thanks to all of you who are building and supporting LinuxCNC. I have found many resources to help get me started.   I'm sure I'll have some questions, and probably a build thread. 

Just wanted to say hi.
