Tomorrow we bake

Milly is coming along nicely.

Finally, a new and excitingly different error message!

Next up will be an extended 30 hour bake session to try to revive the emitter. I don’t trust her to run the heater unattended, so I’ll be staying over at the shop to keep an eye on things.

This is the specimen chamber pressure. The gun is all the way down to 5e-11, pre-bake!

Keep your fingers crossed. With any luck I might have some images to post on Sunday evening!
