CO2 powers vs request
Lasty night I added some lines to Kevin's script that I hoped would make the CO2 powers step down from 1.7W to 0.9W at midnight.
ezca['TCS-ITMX_CO2_LASERPOWER_POWER_REQUEST'] = 0.9
ezca['TCS-ITMY_CO2_LASERPOWER_POWER_REQUEST'] = 0.9
time.sleep(1)
ezca['TCS-ITMX_CO2_LASERPOWER_COMMAND'] = 1
ezca['TCS-ITMY_CO2_LASERPOWER_COMMAND'] = 1
As the screenshot shows the CO2 powers ended up at 7.8W for ITMX and 5 W if ITMY, which caused the PRG to drop and a lockloss.
