I had to spend ~2 hours chipping off some clear resin parts because they were aggressively stuck to the build platform.

I did a alignment calibration and printed another smaller clear resin build and it came off decently.  
I have since printed two Rigid 4K parts and the level of adhesion seems to be increasing over time.

I’ve already upped my Z fine tuning to 50um and might try again with a significantly higher offset (eg. 200um).

I’ve only encountered this once or twice on the Form 3 machines but they usually more or less always released easily but ever since getting my 4L the adhesion to build plates seems way too high.

Has anyone else encountered this problem?
