@rsim, @xquared and I spent the afternoon working on the laser cutter, and we have some bad news. We suspect the laser's power supply also failed when the laser tube burnt out. We're going to order a new one.
There is also some minor issues regarding the cooling system that resulted from the cleaning and preparation for replacing the tube. As these things go, as soon as you fix one thing, a couple others break.
So I'm sorry to report that the laser could easily be done for a couple weeks while we sort this out.
