The temperature changes at EX due to the vent and FAC controls adjustment had pushed BRSX out of range. This afternoon, I used the picomotor in the BRSX can to recenter, by going to LSC->Picomotors->ENDX. I set the channel to 5, enabled the driver and waited for the driver to finish enabling. I then moved the motor 5000 steps positive, from -2250 to +2750, then moved the motor -1000 steps to disengage the mass adjuster, so final pico position is 1750 steps. This moved the driftmon channel from the max negative value -16k to around +9k, so the total move of the spot was more than 25k "cts". I have changed the heater voltage from 3v to 5v, which should move driftmon a bit closer to center. After making the move, I attempted to log into the beckhoff machine and got some error about "received certificate is not trusted".  This was eventually resolved, but Erik had to restart the Beckhoff machine to fix it, so the PLC, BRS C code and epics IOC needed to be restarted. Everything looks good for now, heat is moving driftmon in the right direction, brs is damped down after the pico move. I will check again tomorrow morning.
