It took about 8 hours total to do the mount and OTA maintenance. This included a complete cleaning and regreasing of both motor boxes and both RA and DEC axis worms and main gears. In addition, I added a new USB cable and cleaned up the wiring on the outside of the OTA.
A new PEC file was created using about an hour of acquisition time and 9 cycles of the worm gear using PemPro V3 (v3.10.09). Peak to peak after quadratic fitting was 6.5 arc seconds.

After loading the new PEC file to the mount and running the new analysis (3 worm cycles), the resultant peak to peak is now 0.65 arc seconds.

This evening, I spent time (about an hour) collimating the OTA.
Here is a single 30 sec image of NGC 6811, and open cluster in Cygnus. Stars look perfect.
Later tonight I will be doing the final tests to see that the mount runs as smooth as possible.
