Recalbrating

[Jeff Kelly]

 Good day to all! I'm having to recalibrate every session. I"m set up on a permenent pier. I also have to recalibrate after meridan flip. I have adjusted my loadstar sensor to the correct orientation as close as I can. I did a seaech and could't find a match, probably missed it! After I calibrate it works well. Could you please help me get it working?https://openphdguiding.org/logs/dl/PHD2_logs_BbaN.zip

PHD2 was trying to tell you what was wrong with this alert:

20:47:55.497 00.000 28328 Alert: PHD2 is not able to make sufficient corrections in Dec.  If you have just done a meridian flip, check to see if the 'Reverse Dec output option' on the Advanced Dialog guiding tab is wrong.  Otherwise, check for cable snags, try re-doing your calibration, and check for problems with the mount mechanics.

To take one example, you were guiding ok with the session at 20:12 from side-of-pier west, then you did a meridian flip and started another guiding session from side-of-pier east - and you got runaway Dec guiding. So the alert applied directly to your problem.  For your mount and driver, you need to set the option to 'Reverse Dec output after meridian' flip on the Guiding tab of Advanced Settings.  Then do one more calibration with the Calibration Assistant and you should be good to go.
