Hi Mike,
PEMPro reads the Gemini 2 settings using the Gemini ASCOM driver. It could be that communications failed intermittently between the Gemini driver and the mount, leaving some parameters missing when PEMPRo tried to read them.
I can look at your logs if you use the PEMPro Log Zipper (in the Wizards menu) to zip all of the logs and Debug logs. You can attach it to a post here.

Subject: [Losmandy_users_io] Problem with PEMPro not drawing in all needed G11G (Gemini 2) Mount & Camera
info for valid PE review and analysis
Hi, I posted an issue over in CN Software, but I don't seem to be getting someone who may know the answer. I
decided to map out and see about improving the basic PE in my mount using PEMPro. I have solved an earlier
issue with connecting the mount and camera, but now, on the data gathering runs I have made o far, I can't get
the log files to consistently suck in all the complete mount/camera scale information and tracking data for that run
that allows proper analysis and follow-on PEC curving when reviewing the data. There has been a few
occurrences when it did get all the right info, but I can't figure out why on some runs and not on others, usually
the ones that worked are after I repositioned the scope, but I don't think it has anything to do with the
repositioning, but rather with the integration between the information coming from ASCOM on the mount and
camera, versus what is loaded into PEMPro directly or as default. Or maybe the way I connect the devices, but I
have tried different things and there is no consistency to when this happens and when it doesn't. I have run the
mount wizard and the calibration wizard, I get thru those ok, but it seems to have no affect. On the log files with
the missing info, PEMPro wants to use its default values (such as worm period of 10) to create the PE chart and
PEMPro Log Viewer will not properly run on those files at all because of the missing info (it doesn't have default
values) , if I cut and paste in the info from the runs that did work I can get Log Viewer to work on those files.
On the collected data side, on those data runs that have the missing mount/scope info, there is also a missing
data element that is seemingly important, it is the value in the column with the Controller Step for each exposure,
that seems to be important for curve loading, it puts 1's in there instead of the step location....below are examples.
I am sure this is something simple, like what I am connecting first, or how I set up for the runs, but can't figure it
out. BTW I do have to Bin 2 just to get it to work thru calibration due to the file size on Bin 1 on that camera. Any
ideas are appreciated.

I will explore all the info that is out there on analyzing, fitting a curve, the 76 sec issue, etc. I just need to get past
this operational stuff first.
Thanks
