When defining mesh bed leveling area, Which is the Reference?

Steve Lynch

When defining the mesh bed leveling area, do you set the coordinates based on the position of the nozzle? or the position of the Probe?

So like if my nozzle is at X40, and My probe is -40 offset in the config, do I need to go to X50 to make the probe probe at 10? or does the software automatically know where to go based on my nozzle's current position?

I'm following the tutorial https://duet3d.dozuki.com/Wiki/Using_mesh_bed_compensation

but it does not specify.

Thanks!

Yes. I think that sounds right.

For example, for me I have...

M208 X0 Y0 Z-0.5 S1                                   	; Set axis minima
M208 X325 Y273 Z300 S0                             	; Set axis maxima (x has 295 printable reach)
M557 X10:280 Y35:270 S12.6				; Define mesh grid for full bed print
G31 X-43.2 Y31.9 Z2.132 P25

The coordinates are the area you want the probe to go.

So like if my nozzle is at X40, and My probe is -40 offset in the config, do I need to go to X50 to make the probe probe at 10? or does the software automatically know where to go based on my nozzle's current position?

The software takes account of the Z probe offset when placing the print head for probing. So if your probing area starts at X10 then the firmware will place the nozzle at X50 to put the probe there.
