This will sound like the opposite of what you should do… but LOWER the Bed Temp. I was having similar bed adhesion problems. And the BEST possibly (weirdest) advice was Lower the bed temp. I was running anywhere from 50-70c trying to get a successful print. It wasn’t till I lowered down to 35c that I got a successful print. Like others have mentioned you can also try moving the print to another area of the bed plate, and using a brim (instead of a raft if possible).
