Loadmeters, spindle and servos ???? was created by Jake
I am wanting to get my Hurco to run a bit faster, especially with trying to run aluminum dry. I need to setup the spindle and servo load meters. They are an analog signal from the devices 0-10 volt. I know I will have to convert the analog signal back to a digital signal for my PPMC. I though Jon had told me it can handle 10bits, so I was going to find a converter that can at least handle that. I am torn on using it as a real-time component as its not required for motion, just a tool that can aid in me pushing the machine a bit closer to the limits and reduce the instances of going to far.
www.linear.com/product/LTC1856 this should be an easy converter to use.
What do yall think? this is a rough idea at the moment.
Thanks!

In theory you could connect the load meter to motion.adaptive-feed. That would be neat.

Adaptive-feed would be neat, could have it back off when reaching the limits. Which will be real nice in running aluminum near dry conditions. I'll be happy if I can get the meters to work for now. Just be able to watch the run with my finger on the feed hold button. I should have the new shop buttoned up and machines moved in the next couple weeks. Then I will have some time to work the bugs out of the tool changer and get this project going.
