Klipper: Bed mesh calibrate - Move out of range

[mbgroot]

Greetings!
When printing, I found a “lens” - in the center the distance from the nozzle to the table coincides, but to the edges it is smaller and the nozzle touches the table. I decided to increase the area for "bed mesh" and indicated the points 100,100 and -100,100 in the config. At the beginning of the calibration, I received an error:
Move out of range: -100.000 -100.000 5.000 [0.000]

Maybe I'm doing something wrong? How to properly remove the "lens"?

Sorry, I understood why this error is displayed. I miscalculated the coordinates.
The question about the "lens" is relevant.
Thank.

This is because you have a delta printer, and a square mesh cannot cover a significant portion of a round bed.

I'm working on a solution for this, but currently I don't have much time to dedicate toward it. It may not be until December until I have the time to dedicate toward the fix, but it will come.

I found the same "problem"...
prepared logfiles, startet to write an issue.... ... and found this ;)
Do you have some news?

I do have some code that should be able to probe a radius on a round bed, I just haven't got around to testing it yet. Right now I'm doing some filament sensor work, when I'm done I'll do some basic testing and submit a PR, where folks with delta printers can test it better as I myself do not have a delta.

Ready for testing!

Please see Pull Request #1177 if you are interesting in testing support for probing round beds.

Here!
but I don't know how to install it. tried to copy the bed_mesh.py by hand.
but klipper says Option 'radius' is not valid in section 'bed_mesh'

edit: bed_shape: round was missig in my config.
tested shortly, seems to work. Nice job!

@klHaribo Great, thanks for the feedback.
