Bed Levelling and Compensation

[GeoffCamps]

Hi,

I am in the process of configuring a new CoreXY machine. It has 4 independent Z motors, so I was considering implementing the auto bed levelling to ensure it was planar, then use mesh bed compensation for bed undulations.

Step 1 - Level Bed (G30)
( https://duet3d.com/wiki/Bed_levelling_using_multiple_independent_Z_motors )

Step 2 - Mesh Bed (G29)
( https://duet3d.com/wiki/Using_mesh_bed_compensation )

But the wiki says "On a Cartesian printer, you can use either mesh levelling (G29) or G30/G32 probing, not both".

I know G29 alone would work, but my thought is that Levelling before mesh compensation would reduce the work/wear/tear on the z axis as it would need to compensate less.

Would this 2 step levelling work?

Thanks,

Geoff.

Yes, you can use G32 for leadscrew adjustment followed by G29 for mesh bed compensation. Just as on a delta printer you can use G32 for auto calibration followed by G29 for mesh bed compensation.

Perfect. Thanks.
