===== SEM#1 update===== |

The service engineer had to order some more parts for the SEM. He’ll be back tomorrow to continue troubleshooting the skewing issue. In the meantime, the tool is useable and is only showing the skewing issue within the mags of 5.5k to 8.5k. Please let me know if you encounter any other issues. Thanks, Aidan |

I am fairly certain the heater controller has failed. I have spoken with the vendor and they are looking into it, but we will most likely have to send the unit in. I will push to have a replacement controller sent instead, but since this is a warranty repair they will probably want to eval it in-house. I would plan for it to be down for at least a couple of weeks. I'll send out an update once I have more info. |
