Probe Count Issue using Bicubic with Long Narrow Print Size about print_area_bed_mesh HOT 6 CLOSED

According to the klipper source:

        elif params['algo'] == 'bicubic' and min_probe_cnt < 4:
            if max_probe_cnt > 6:
                raise 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: %d, %d" %
                    (self.mesh_config['x_count'], self.mesh_config['y_count']))
            else:
                logging.info(
                    "bed_mesh: bicubic interpolation with a probe_count of "
                    "less than 4 points detected.  Forcing lagrange "
                    "interpolation. Configured Probe Count: %d, %d" %
                    (self.mesh_config['x_count'], self.mesh_config['y_count']))
                params['algo'] = 'lagrange'

bicubic only allows a minimum of 4 probe points. I'll change the minimum to 5 if bicubic is used.

macro has been updated with the changes. Let me know if you're still having issues with this.

from print_area_bed_mesh.

Thanks, I'll look into it later today.

If I understand correctly a 2x2 grid is 4 points so it satisfies the 4 point minimum requirement.

I see that you have added a statement for homing the axes.

I think you should add another statement following the G28 call

{% if printer.z_tilt.applied != true %} Z_TILT_ADJUST {% endif %}

from print_area_bed_mesh.

I don't think the rest (z_tilt_adjust, _quad_gantry_level, homing z afterwards, waiting for bed/nozzle to heat up, etc.) belong in this macro.

I wondered why you had a check to see if the toolhead was homed in the XYZ axis in there. It made sense for me to check if the Z was level as well as homed.
