@kninedhp said in Mesh Bed Compensation and Bed Leveling:

I think i found it i at some point lost a S3 in bed.g

That would explain it. Without S3 on the last G30 command, it won't adjust the leadscrews.

Also I notice that both the last two G30 lines in bed.g use P2. So the 4th point will overwrite the 3rd one. Change P2 to P3 on the last G30 command (as well as adding the S3 parameter)..
