PHD guiding - my graph is a sine wave :(

Hi guys - Im pulling my hair out over this one. Im having lots of trouble getting my CGEM to guide properly with my new skywatcher Mak newt.

With guiding enabled the PHD graph is a nice sine wave - my images are useless

Ive balanced very slightly to the east, and have also checked and re-checked that there is no binding happening, but I simply cannot get a smooth graph.

The polar alignment seems to be ok - Ive done multiple iterations of the All star polar alignment routine.

Any ideas? Im using a finder guider, and have tried tweaking the settings for shorter focal lengths.

I seemed to get better results with my little 90mm refractor, so Im thinking that the skywatcher might be too heavy for the CGEM...
