Diagnosing sputter chamber computer

The sputter chamber computer failed last week. With Ryans assistance I took the computer apart and was able to find that a MOSFET in the power supply failed. I have ordered a replacement for $7 and I expect it to arrive within a week. Soldering in the new part should make the repair barring other problems we don't know about.
I will try to see if parts has another computer/power supply to have as a backup.

I have continued to work on the galvo controller and it is capable of relative and absolute motion. Now I need to have Ryan show me how he imports images and controls the shutter so that I can have the galvos make an image.

I have found an alternate supplier for the rough pump oil but I still need to find a rebuild kit.
