D33017 Could not perform Spectrometer Optimization, Peak too weak
Issue
Customer 1 Problem:
"Journal is showing the D33017 - Debug could not perform Spec. Opt., peak too weak or not found error when I first started it up but then I did the optimization again and it looked like it would work. I started an analysis but the wavelengths were coming out bad. Some of the wavelengths looked OK but most of them were not. This is very typical of what is happening. Some days I can’t even get it to optimize."
Customer 2 Problem:
"I encountered another drastic decrease in my signals while running samples. I rebooted the system but it didn't help and I once again encountered "D33017 Could not perform Spectrometer Optmization, peak too weak.." I tried to run a fullframe and I got a very odd result (see attached). What do you think could've caused the recurrence of this problem?"

Resolution
Appears to be a possible Fore Optic and/or shutter/slit mask issue. The plasma emissions are not being directed into the Optic tank. Which is also what the FF image you provided indicates.
If a FF image shows very little emissions, then we're not getting near enough light into the spectrometer to give us the emissions we need. Fore Optics mirrors may be oxidized or motor positions may have gotten corrupted and needs to re-alignment, even though in this case C 193 x,y position is good.
Solution 1:
FSE found the problem was the cable harness for the M2 motor was getting in the way of the M1 mirror movement. If you look at the center of the .jpg you can see the yellow/black wire holding up the movement of the M1 mirror at the black plastic mounting post the spring attaches to.
Solution 2:
FSE noted that the duo slit mask appeared to be not fully uncovered when he compared it to his reference images for duo slit.
The shutter/slit mask assembly is likely defective. After changing the slit mask a fore optic alignment may or may not be needed, a torch alignment first will typically reposition everything just fine. If that fails because of corrupted motor position data then a full fore optic alignment is needed.
