End X BRS has been drifting more out of rang over the past week. The BRS originally got out of range a month ago (LINK ALOG) I'm boosting the drift control (H1:ISI-GND_BRS_ETMX_HEATCTRLIN) from 4V-->8V to try and get it back to the temperature the plate was before it started to get out of range.
The original temperature is ~36, and right now H1:ISI-GND_BRS_ETMX_HEATTEMPL is reading 27.0, but I'm hesitant to max out the drift control as it was set to 6V when it was last in range.
I'll check back in on it later today/this week
Moved the heat control down to 6V because 8V increased it up to 41
I ended up using the pico motor and remote mass adjuster to try and re-balance. Here are some of the relevant alogs: 76888 75802 80183 84434
From an earlier alog we had calculated ~3.2 counts per step, currently DRIFTMON=~12220, so it should move 3.8k steps, but from other times it's been moved it seems like the steps per count might be less, so I'm going to start with a smaller step amount and check back in later today or tomorrow morning.

To couple :-1.5k in steps of 100, waited a couple of minutes for it to damp down
-2k in 100 step chunks, I don't know if moving in smaller chunks did anything, but it somehow felt better
+1.25k to decouple
Total moved: -2250 steps
