linuxcnc.org/docs/2.4/html/examples_spindle.html

Has some open loop examples
(you would have to change the hardware pin names)

I am retrofitting a Lathe with EMC. 30 Hp Reliance DC motor and spindle drive. My problem is following errors on the spindle joint......If I try to spin the axis by hand with EMC in the run state I get a following error

This is rather odd.
Which axis shows a following error?
Is it possible that the resolver numbers are mixed up? Can you check in machine->show hal config ("Watch" tab, the other tab isn't updated live) that moving the spindle changes the value of resolver.00, and that X and Z are on Resolver.01 and 02 ?

You are one of the very first users of the Resolver driver, so it is possible that there might be a mix-up inside the code.

My spindle is fine........I was getting feed back on my x axis that was actually my joint error. I was hasty with the error.....because every time I touched the spindle I got the following error. I am goung to move the x axis away from the spindle on the resolver board. Thanks for the help today.
