Mesh levelling on 3.1.1
-
@Veti Do you mean the G30 needs the g28 performed prior?
G29 is only performed intermittently to establish the bed map, not every time we print. The full procedure for the mesh levelling was followed.

For the G92 Z0 to be valid the actual Z position must also be zero.

That line is incorrect.
You should have at least the P X Y and Z parameters but you have none and a value all on it's own.

@fcwilt 0.71mm

@lael said in Mesh levelling on 3.1.1:
@fcwilt 0.71mm
OK so the end stop triggers are 0.71 and at the point the Z axis stops moving.
Is that the actual Z position of the nozzle.
If you include the G92 Z0 you are telling the firmware that the Z position is 0.
So where exactly is the nozzle tip - at Z = 0.71 or Z = 0.00 or perhaps something else?
Thanks
Frederick

Can we see the code that you use to create the height map?
Thanks.

@fcwilt so far I've just been running through the mesh levelling tutorial / example and haven't made a macro for it. To remap I've gone through the entire procedure manually.
In terms of the nozzle tip, you mean relative to the bed?

Did you do a G30 prior to the G29 that actually started the probing of the bed?
In terms of the nozzle tip, you mean relative to the bed?
Yes.
