Thanks for sharing your experience, Ben! I think you might be onto something about the autotune setting the EM high. Since I started here the EM has been tuning way higher than I'd expect for it's age, even the new one installed by the engineer last week. Something is going on there, but I don't know enough about the tuning process to know what could be affecting the EM voltage this way.
Unfortunately, I could not find a "reset default" type setting in this software (I agree this software is a misfortune haha). However, I found a way to set the maximum final EM voltage. I tried setting this to 1350, but still the tune would not complete. Received the same error of "Unable to set appropriate values for low/high mass resolution." I can manually tweak the tune to get ok values, but it very much worries me that the MS cannot complete an autotune.
Yesterday I tried using older tune files (even deleting the newer "bad" ones to avoid the software using those pathways). No change.
An engineer is coming today to install a new main board, so we'll see if that has an effect.
Thanks again!
Mass resolution error could be related to peak widths not being where they should be or not being stable, which is either dirty quads or the electronics that run them. If you have a tune that can scan, watch the peak widths. If you scan for an hour or two and they get wider or narrower then that is where the problem is. Of course that would be with the cap in place of the column, since a lot of air can cause drifting peak widths also.
