    Looks like you have it set to load the profile “default” instead of “bed60”

    Also worth asking, did you have your start gcode set in your slicer previously and if so, did you delete it out of there now that you’re using klipper macros?

      Yeah forgot that I switched to default again to make sure it wasn’t something with the different profiles messing it up. I manually update the mesh before every print now.

      I did have my start gcode in the slicer before, but that’s been replaced with the macro.

        I’ll try to check mine when I’m back home later. I just use the default profile since I don’t ever adjust anything with the bed unless it’s out of spec. Even printing at slightly different temps doesn’t seem to affect anything as far as bed leveling is concerned.

    Could you also post the [bed_mesh] section of printer.cfg?

      Sure

        What type of probe and what’s the config on it?

        pin: PC14
        x_offset: 23
        y_offset: 5
        #z_offset: 0.10
        speed: 20.0
        samples: 5 
        samples_result: average
        sample_retract_dist: 1.0
        #samples_tolerance: 0.010
        #samples_tolerance_retries: 10 
          
        Is what I've got my pinda probe configured with, was playing around with sample tolerances like I have on my printer with a tap probe but I just found the inductive probe has a lot of variation, I added more samples to hopefully average out that error. 
        
        ```[bed_mesh]
        algorithm: bicubic
        fade_start: 0.6
        fade_end: 10.0
        bicubic_tension: 0.2
        faulty_region_1_max: 120.0, 74.0 
        faulty_region_1_min: 85.0, 45.0 # 103,69
        faulty_region_2_max: 125.0, 165
        faulty_region_2_min: 70, 110 # 103, 137
        horizontal_move_z: 2
        mesh_max: 228,210
        mesh_min: 24, 6
        mesh_pps: 2, 2
        probe_count: 5,5
        speed: 200
         
        Is my mesh setup, based on a [mk3s klipper config](https://github.com/dz0ny/klipper-prusa-mk3s). Meshes look a little odd but I ran some bed level prints fine and just ran a full plate of abs with pretty consistent 1st layer.

    I’m not at my computer now to be able to give specific examples but this most surely sounds like something wrong with the start gcode and klipper not loading your saved mesh before running the print. I’d double check the docs and make sure you have the correct gcode to load your saved mesh.

      Made a different reply with the start macro I use, I checked and it is the one I use.
