Warping while printing PEEK

[LeglessPooch]

I recently picked up a CreatBot F430 to print some PEEK parts but I'm having a hell of a time getting the raft to not warp. I'm using UHU on the carbon fiber plate they sent with it. I'm printing at 400C and bed at 145C. Any XP with printing with PEEK would be greatly appreciated. EDIT: I no longer have raft warping problems but now my prints are failing bc the parts aren't sticking to the raft. I'm not sure if I need to recalibrate but I'm going to start there. If anyone else has any ideas they would be appreciated.Thanks for the help!
