Trust me, I want to get it sorted!
I'm pretty sure it is not software related, PHD passes it's calibration and I see the guide star move in all 4 directions during the process. I tried .3x , .5x & 2x guide speeds on the Losmandy drive system, each with various backlash settings and various aggressive settings from 30% to 100% - forcing PHD to do a calibration each time, all to no avail. I always lose the guide star with it drifting East though, so the RA is pushing it too fast. I think it is a mount issue, I bought the mount earlier this year second hand and pulled it apart and regreased it (it's about 10 years old with the grease turning to slug problem common to older G11's) and I think the problem might lie with the RA worm gear not being flush to the RA gear from when I put it back together. I might offset my azimuth next time and drift the star through an image that I take with the DSLR to see what the RA gearing is doing exactly. Theres other people on the net reporting this so called "76 second error" which arises from the worm block not being flush, so it's the first thing I'll look at.
Once I get the problem sorted though I look forward to using this setup! Plenty of targets a non modded DSLR can hit before I will feel the need to move on
