I am running Marlin 1.1 and have turned on MESH_BED_LEVELING since I don't currently have a working probe. I'm using the default 3x3 mesh grid.
After I perform the manual bed leveling (G29 S1, G29 S2, ...) all seem good. I get the following output with G29:
Send: G29 S0
Recv: State: On
Recv: Num X,Y: 3,3
Recv: Z offset: 0.00000
Recv: Measured points:
Recv: 0 1 2
Recv: 0 +0.50000 +0.40000 +0.20000
Recv: 1 +0.60000 +0.50000 +0.20000
Recv: 2 +0.50000 +0.40000 +0.00000
Recv:
Recv: X:0.00 Y:0.00 Z:0.00 E:0.00 Count X:0 Y:0 Z:0
It seems reasonable. But, later on, after I do a print to test the leveling, G29 returns:
Send: G29 S0
Recv: State:
OFF
Recv: Num X,Y: 3,3
Recv: Z offset: 0.00000
Recv: Measured points:
Recv: 0 1 2
Recv: 0 +0.50000 +0.40000 +0.20000
Recv: 1 +0.60000 +0.50000 +0.20000
Recv: 2 +0.50000 +0.40000 +0.00000
Recv:
Recv: X:0.00 Y:0.00 Z:0.00 E:0.00 Count X:0 Y:0 Z:0
Plus, anecdotally, my prints don't appear like they've been "mesh-leveled."
Does "OFF" mean that bed leveling is not being applied? If so, how did I turn it OFF and how do I turn it back ON (w/o re-doing the whole 9 point z height adjustments)?
