I just received my MKIIs yesterday and ran into the same issue, but what might help is placing the provided spacers / washer from Rane underneath the slipmat. I feel as though the MKIIs come with a lot of friction outside of the box which cause them to drag the platters.
Not sure if this actually solves the issue, but it’s worth a shot. I have 3 spacers underneath my mats but have not been able to test enough. Below is a video of what I’m talking about:
Update I checked quickly with and without the spacers and while they do reduce the drift somewhat, unfortunately, there still seems to be drift…so not sure what to think. Next step is to test with Serato and compare
