Have a "new to me" LX200R 16", and up until about a month ago PHD2 was doing great with calibration and guiding. I've got it set up in ASCOM with the meade LX200GPS/R driver, and I've deleted and reloaded both and it and the PHD2 program multiple times in the last month, so they're both up to date. I still had a residual 1.5 arcsecond error in RA that was driving me bonkers so I went in and cleaned/regreased both RA and DEC drive worms, beefed the springs up, and also downloaded PEMPRO trial version and tried (with no success) to get it to dump a better correction curve onto the PEC. After all of this, I tried to set up and run PHD2 again and found to my horror that it REFUSES to complete the calibration. It will perform the RA (or west/east) calibration, but when it then goes to "clear the backlash" it will send clear commands for hundreds of cycles w/ no tangible result, and subsequently the DEC calibration never completes. BUT WAIT! It gets better! "It's your cable!" I hear you say, but i can put it in manual guiding and it moves quickly and w/ very little backlash to any command either north or south sent to the mount via the phd2 manual guiding. Which tells me the cable, and serial to usb adapter is working fine. But it refuses to send declination commands either in calibration or in normal automatic guiding. I have looked at the guide logs and they mirror that. Also of interesting report is that the calibration graph shows that the RA/DEC axis are colinear. And by that I mean they exhibit 88.8 degrees of orthogonality error, so essentially colinear. When you watch the guiding graph, the declination error and the RA error or ON TOP of each other, ie the same. It's like somehow the declination axis has vanished from the telescope. I'm wondering if pempro somehow made a deep dark firmware change to my scope's control system?
Anyway, I'm about ready to pull my hair out, and I'm open to suggestions. I've attached one of the dozens of log files which thankfully don't record audio or you'd hear a stream of astronomy focused profanity.
