Hi, I appreciate this post was a few years ago. But I have had the same issue and have been told by Pokeys that direction and pulse does not work for threading on the lathe. They are trying to find a solution but not for the immediate future.
I am trying to control the servo with 0-10v, which would allow threading. But am having problems with enabling and the servo direction. The 0-10v to the servo works fine.
If you had a solution I would be interested to hear it.
Thanks.
