want to center the sample with G1 Z1 (mesh bed compensation)
-
when I want to center the probe (preparing mesh bed compensation step by step) with G1 Z1...the probe doesn't move a little in x and y but only z
Here my config g:

@axiom can you provide a little more information on what it is you are doing, what it is you expect to happen and what actually happens? So for instance what commands are you issuing and how are you issuing them?
-
@gloomyandy i want to follow the mesh bed compensation step by step guide (https://duet3d.dozuki.com/Wiki/Using_mesh_bed_compensation). I could go to any other point without any problems...but I think if this command doesn't work, something fundamental is wrong
-
@axiom I think you may have misunderstood the instructions it sounds like you are trying to follow this step:
Command the print head to the coordinates you want to probe. To probe the center, send G1 Z1.which is perhaps a little ambiguous. The G1 Z1 command will only move the print head in Z and will position it 1mm above the bed (or atleast 1mm above the current Z=0 position). It will not move the print head to the centre of the bed. You will need to to that by issuing extra commands (or using the DWC movement commands), so for instance if the centre of your bed is 150, 100 send G1 X150, Y100 (make sure your nozzle is clear of the bed before doing this by running G1 Z5 or something similar), you can then use G1 Z1 to lower the nozzle to be 1mm above the bed for the rest of the procedure.
Oh and the instructions you are following have moved to the new documentation pages. The "new" version is here: https://docs.duet3d.com/en/User_manual/Connecting_hardware/Z_probe_mesh_bed I couldn't see any updates but it makes sense to use the current version.

@gloomyandy I actually got that wrong! Thank you very much and then I will follow the new instructions.
All the best! -
@gloomyandy said in want to center the sample with G1 Z1 (mesh bed compensation):
To probe the center, send G1 Z1.
which is perhaps a little ambiguous.Thanks for pointing this out, I've updated the step to say:
- Command the print head to the XY coordinates you want to probe. This can be any place where both the nozzle and the probe are over the bed. Either use the jog buttons in DWC, or send a G1 command (eg G1 X100 Y100) to move to a specific location.

@droftarts thank you ian
