I have something exciting to report. I was successful in recording a PEC curve with 32000 steps. It seems there is
a bug with Gemini II PEC recording. When I first attempted to record a curve it stopped after 6400 steps. Since
uploading the dummy test file where the PECmax variable set to 32000, it now seems to work just fine. Go figure.
Here is the curve I recorded. I like its fine detail.
1. Either your graph is incorrect, or PEC is introducing a lot of drift. By the end of the worm cycle the accumulated PEC value should be 0 (but it's not).
2. Whether PEC is using 32000 should be confirmed by sampling the PEC index from the mount.
