Mesh Bed Compensation and Bed Leveling

[KnineDHP]

I have a Railcore and something is not working with bed leveling and the Mesh grid. both my right sides are -Z and both the left are +Z the bed leveling should fix this. i will post the configs below.

What i don't understand is why is it not just lowering the left or raising the right to get it closer?

Thank you all in advance for looking at this.

Any thoughts? Days of trying and I can't solve for this.

Can you post your homing files? and your Bed.g? Maybe also config?

@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)..
