After various ETMX transfer functions and offset tests, it looks like ETMX isn't rubbing anymore!

I did these tests this morning and wasn't able to get any rubbing. For everthing I did, L1 LL (and everyone else) moved as expected and no one got stuck anywhere. The offset tests that I did involved putting offsets in the L1 COILOUTF banks, M0 TEST banks, and R0 TEST banks and making sure L1 osems were all responding how we expected them to.

We noticed that L1 UL has been a little more jaggedly compared to the other L1 osems since we went to air, but the osem spectra looked good (comparing to its brethren) and putting a drive in M0 to move L1 around shows that UL is moving and behaving normally. We think it's probably just related to its current flag vs osem position as we put air in the chamber.
