We've had another rotation stage failure.  

We noticed the same behavior on thusday night.  We can type in a requested power, the code calculates an angle, but hiting the go to power button doesn't cuase anything to happen.  On thursday as well as the first time that this happened today (around 23:00:12 UTC on Feb 14th) typing the calculated angle into the requested angle box and going there worked.  Patrick looked at trends from thursday night, and it looked like I had not changed the requested power before hitting go to power, but today I am sure that I did, and we have the same behavoir.  

After that happened, I tried to adjust the power using the requested angle, which then stopped working, so I couldn't move the rotation stage without first going to home.  Now that I've gone to home both buttons seem to be working.
