Could you post a pic of the drive side cup? I run the same setup and i feel like the right side adapter is loose. It doesn't sit flush to the frame.
(Sry hijack thread)

Hijack away mate. Mine sit flush against the frame but I can't say if it walks out of the frame under pressure. Internet say that you really should put some glue on the nds cup when you press it in so it stops from wiggling. I might just do that if the KCNC doesn't work.
If it comes to worse and I need to switch it out I'll just saw it out of there. It is plastic after all. ;) -
Will do later today!

Sorry, I forgot about the pic until I did a ride on friday. noticed some rubbing coming from the crank/bb area. chainring bolts were rubbing on the driveside chainstay because the limiter of the gxp bb could not hold the spindle back and in its place (hope that makes sense). It turned out the nds of the sram adapter was pushed out a little. pushed it back in (with tools) and everything is in its place again but cant tell if it stays there as I havent been able to test it afterwards. Just wanted to confirm your issue with loose cup!

Using the same PF30 Sram adapter for my CNC frame. Put a standard threaded 68mm GXP bottom bracket in and fitted a sram rival crankset. Works fine. No spacers or washers needed!
