Re: EMC stepper & misc fixes

I downloaded and installed the new build with no problems tonight and had a
few minutes to play with it. The Verify button is a big improvement in my
mind as we can now at least parse through some code real quickly without
having to run the machine or start up a simulation. I played with using the
Run From Set Point as Matt suggested, but found that it was a little flaky
about starting at my chosen point. Seemed to work sometimes and not others.
The Verify button seems easy to use and reliable.

Thanks Fred for the rapid updates!!
