Adaptive Mesh: Did I find an error?

I have 2 longer objects on the bed and as soon as the mesh would get created, Klipper runs into error.

 bed_mesh: invalid probe_count option when using bicubic interpolation. Combination of 3 points on one axis with more than 6 on another is not permitted. Configured Probe Count: 3, 7

 bed_mesh: invalid probe_count option when using bicubic interpolation. Combination of 3 points on one axis with more than 6 on another is not permitted. Configured Probe Count: 3, 7

How to fix this behavior?

Yep i think you did find a bug. Please give this a shot (throw it in user overrides):

Original macro seems to be missing:

{% set mesh_count_x = ([min_mesh_count, mesh_count_x]|max)|int %}
{% set mesh_count_x = ([max_mesh_count, mesh_count_x]|min)|int %}
{% set mesh_count_y = ([min_mesh_count, mesh_count_y]|max)|int %}
{% set mesh_count_y = ([max_mesh_count, mesh_count_y]|min)|int %}

{% set mesh_count_x = ([min_mesh_count, mesh_count_x]|max)|int %}
{% set mesh_count_x = ([max_mesh_count, mesh_count_x]|min)|int %}
{% set mesh_count_y = ([min_mesh_count, mesh_count_y]|max)|int %}
{% set mesh_count_y = ([max_mesh_count, mesh_count_y]|min)|int %}

after the algorithm checks, so i added those.

Okay, will try it later. Just now I "repaired" this issue by adding something else at the side... and excluded it from printing after the print started. Need to wait now for finishing this print.

i think this is wrong this would change a 3x6 mesh into a 6x6 mesh or am i seeing it wrong

miklschmidt•2y ago

it would limit x/y probe counts between min and max mesh count.

yes, original PAM did it a bit different
