Re: Gemini 2 L 6.02 Needed to Be Re-Flashed

 

?
PEC shouldn't work after a full reset, and programming the same PEC curve shouldn't work either. Gemini keeps track of the current worm position in memory. When you reset all settings or do a reflash that does the same, Gemini will no longer remember the correct worm position. As the result PEC will be played back out of sync (out of phase) with the actual worm error, which is likely to make tracking error even worse than without PEC. If you want PEC, you'll need to redo PEMPro calibration/capture/program steps one more time.

Thanks for that, Paul.

It sounds like you are saying something like an HGM Reset on the HC (not looking at it now, but that's my recollection)?
?
I had run PEMPro 7 months ago, when I first flashed the 6.02 firmware, and my guiding got superb.? After last night's reflash, I noticed the reflash wiped out my PEC data on the table, so I just uploaded the same PEC curve from 7 months ago.? My RA guiding was lousy after that.??
?
I then tried just training the drive from the HC, it seemed to be improved, but I think I need to collect data by camera and rerun PEMPro again.
?
Do you happen to know if L6.02 is improved for PEC training via the HC vs. L5.0?
?
Let me know if an HGM Reset on HC is what I needed to do.

Thanks so much.
