G28 G29 P1 Mesh invalidated. Probing mesh. Probing mesh point 1/9. Probing mesh point 2/9. ... Probing mesh point 9/9. G29 T Bed Topography Report: ( 5,220) (200,220) 0 1 2 2 | -2.099 -0.667 -0.043 | 1 | -0.464 -0.105 [+0.365] | 0 | +0.153 +0.377 +0.664 0 1 2 ( 5, 15) (200, 15) G29 S0 -- save to slot 0 G29 A -- activate M500 -- save everythingThis works just fine. Repeatability can be tested using G29 K0 and it's below 0.01 mm if I do not touch anything between the probes.
G28 Z -- so it moves the head to the center of the bed -- put paper under the head G1 Z0 -- move head down to where printer thinks is zero. M851 -- check settings M851 X-45.00 Y-5.00 Z-0.8 ; (mm) M290 Z-0.1 -- or similar until I just feel some resistance moving the paper M500 -- save again
G28 G29 L0 ; Load UBL mesh values from slot 0. G29 J ; Probe 3 points and tilt the mesh to the plane.Should I save after G29 J?
