Ahh the dreaded blob of death. It’s recoverable as Malc said, don’t worry. As @just4memike alluded to, this is a problem that is caused by a dirty plate. Best practices are:
Do not touch your plate if possible, as finger oils can and will cause this exact issue.
Also be aware of what you’re printing with; If you just printed with a lot of PLA and now you’re going to print PETG, wash your plate because they don’t adhere to each other and prints will leave microplastics behind.
A proper wash should use a gentle detergent (dawn is the general recommendation) and a scrubbing sponge. Thoroughly wash the plate and then dry with a paper towel (not your kitchen towel, it needs to be lint-free), try to only handle the plate by the edges or by the grips where you’d remove it from the bed.
Don’t use Isopropyl alcohol, it can spread oil around and subtly make the problem worse. Don’t use acetone, it can damage the coating on the plates. Detergent, scrub sponge, and a couple paper towels are all you need.
Follow these general guidelines and you’ll have great adhesion
