Be sure to run BOTH TheSkyX and CCDsoft "Run As Administrator" and that CCDsoft->File->Preferences is set for TheSkyX integration otherwise the worm phase data will always be recorded as zero. You can check your tracking log file from CCDsoft to see if they're zero or not.

The East/West button inverts the curve. If PEC makes things worse, try it the other way. Hey, you have a 50/50 chance of getting it right.

I know binning is okay with Tpoint mapping, won't affect the results, but I'm not sure about the effect of binning in PEC training. I'd be leery to bin there. When you record the data, you use a smallish 64x64 or so tracking box anyway, so you should not really need to bin there, I'd think.

Note that unless Ray has fixed PEMPro very recently, it can neither compute a correct curve for nor can it program a Paramount MX mount. You have to use CCDsoft and the built-in PEC curve computation tab in TheSkyX->Telescope->Tools->Bisque TCS->Periodic Error Correction->Compute PEC Curve.
