Rik's problem reproducible. Not a contrast/brightness issue, no image shows up. After S.C. Air Lock Valve is open with a beam on for 20 seconds with no image, S.C. Air Lock Valve toggles open and closed of its own accord (this shuts down the beam automatically), or at least sounds like it does (only done once, then gave up on machine). Misc: Machine set to run at 12uA instead of 10uA as instructions say, but wasn't sure if this was intentional or not.
