This is an issue from last week. While doing chiller maintenance last week I noticed that the power supply for the TCSx laser was running at only half power. I checked the cables and didn't find any obviously loose connections, but this has been an issue in the past. Less likely, but still possible is the RF driver failing. While on the table I noticed the rotation stage has once again gone glitchy and won't respond to requests or return to home. Most likely requires a Beckhoff reset. There is and has been a beam block in the laser path. For now the TCSy laser is disabled by the MEDM gate.
Actually the TCSy is disabled by turning the key off also at the control box (I didnt know about these issues at the time when I started trying to turn the CO2y laser on today (alog to come)).
Also like Greg mentions I would suspect the cable connection if is onlydrawing half current as this has been a known issue on this table before see alog 16495.
