Enable all the axes
I made a benchtesting procedure, while verifying the first chassis myself. I then trained Ivan on how to verify chassis on the bench and field. He then worked independently with Danh Du to complete the checkout for M3. Danh then completed the verification for M2 installation with May Ling.
With each verified chassis we had a solid reference for finding mistakes in cables. A loose wire on the bender motor cable for M1 was discovered. Other errors in the chassis were discovered during benchtesting. Sorting out the problems after chassis installation would have been painful (that's what we tried to do originally).

A dead piezo!
While recommissioning all the XRT HOMS we encountered a piezo failure on M2H. For no apparent reason the piezo died, and we had to scramble to replace it. Actually Corey and Daniele replaced it, while Teddy and I completed verification of all other axes. We don't understand why it failed. Here's the voltage from when it failed:
