My solution... i print with a raft every single time never fails...It doesn't stick to the bed I tried one print without a raft so many times I gave up. I changed the z offset in s3d from .25 to -.35 in .05 increments just in case I was off with my leveling had no success even tried glues tick with these attempts. I'm still doing 30% first layer speed maybe that is why. An adhesive was not needed in repg to start and get the prints sticking I don't know why using another program would require an adhesive other then setting being different. Rather frustrating going to a $140 software to fight to get print success.
I also have a makersome Glass kit coming because people rave about the glass beds
