Brian,
Noticed that CV has changed in one of the last few releases.
My CV was running smooth thru Rel 2.42 then I noticed it started acting like it was in Exact Stop mode.
Sorry I didn't catch it until Rel 2.48 so don't know which release between these 2 started the problem.
I've reinstalled the older release and it works fine. I'm guessing a modification around the first part of September is where it started.
I've been running steppers on my router without any problems for the past 2 years.
Let me know if you need more information.
Thanks,
Tom
