Klipper mesh on print area only install guide

What this macro do

  • This macro will dynamically changing the bed mesh area based on the size of the parts will be printed. The fw will only probe on the area that the part will be printed (plus mesh_area_offset value)

Setup guide

  • (1) Add the following macro to your printer config, this will replace the default BED_MESH_CALIBRATE command.

  • (2) Go to slicer setting and replace the old bed mesh gcode the following command.

Prusa Slicer
BED_MESH_CALIBRATE AREA_START={first_layer_print_min[0]},{first_layer_print_min[1]} AREA_END={first_layer_print_max[0]},{first_layer_print_max[1]}

Ideal maker
BED_MESH_CALIBRATE AREA_START={print_pos_min_x},{print_pos_min_y} AREA_END={print_pos_max_x},{print_pos_max_y}

Cura slicer
BED_MESH_CALIBRATE AREA_START=%MINX%,%MINY% AREA_END=%MAXX%,%MAXY%

*(Cura slicer plugin) To make the macro to work in Cura slicer, you need to install the post process plugin click here to download (based on frankbags's script)
- In cura menu Help -> Show configuration folder.
- Copy the python script from the above link in to scripts folder.
- Restart Cura
- In cura menu Extensions -> Post processing -> Modify G-Code and select Klipper print area mesh

For user using single command START_PRINT

  • (*) If you use single command start gcode like START_PRINT BED_TEMP={material_bed_temperature_layer_0} EXTRUDER_TEMP={material_print_temperature_layer_0} .You might need to add parameter parsing to BED_MESH_CALIBRATE inside START_PRINT. This is an example, also check my macro sample
[gcode_macro START_PRINT]
variable_parameter_EXTRUDER_TEMP: 190
variable_parameter_BED_TEMP: 60
; gcode parameters for area bed mesh
variable_parameter_AREA_START : 0,0
variable_parameter_AREA_END : 0,0
gcode:
    # preheat, homing, etc
    BED_MESH_CALIBRATE AREA_START={params.AREA_START|default("0,0")} AREA_END={params.AREA_END|default("0,0")}
    # the rest of your start macro here

And you will need to change Slicer start gcode to this

  • Cura: START_PRINT EXTRUDER_TEMP={material_print_temperature_layer_0} BED_TEMP={material_bed_temperature_layer_0} AREA_START=%MINX%,%MINY% AREA_END=%MAXX%,%MAXY%
  • Prusa slicer: START_PRINT EXTRUDER_TEMP=[first_layer_temperature] BED_TEMP=[first_layer_bed_temperature] AREA_START={first_layer_print_min[0]},{first_layer_print_min[1]} AREA_END={first_layer_print_max[0]},{first_layer_print_max[1]}

change logs

  • 2022/07/21
    • Added force lagrange algorithm for mesh with lower than 3 points
    • Added enable_reference_index config flag

The code does not work?

  • I will try to help if possible, you will have to post ALL of your configs, your slicer start gcode and your sliced gcode.
  • If I'm cannot or too slow to respose, our discord members might help you. Check our discord here

You can test with, e.g., BED_MESH_CALIBRATE AREA_START=100,100 AREA_END=200,200

tried this and i get a full bed mesh every time i run a test print. the part i'm using is small and i move it around the bed
i committed out the the klicky bed mesh cfg,not sure what i'm doing wrong

To get this to work on IdeaMaker using single Start_Print
(including temp parameters to help those that are new to using Klipper macros and parameters within the Slicer G-Code). If you can copy and paste, you don't need to modify anything.
Copy and paste the BED_MESH_CALIBRATE macro as per instructions above to your printer.cfg file.
If you have a START_PRINT macro already in you printer.cfg file, comment out that section and paste the code below above the code you just commented out. If not, just paste this under the BED_MESH_CALIBRATE macro. Indentation is important.

[gcode_macro START_PRINT]
gcode:
    {% set BED_TEMP = params.BED_TEMP|default(60)|float %} # Setup bed temp parameter and give it a default value of 60
    {% set EXTRUDER_TEMP = params.EXTRUDER_TEMP|default(210)|float %} # Setup extruder temp parameter and give it a default value of 210
    {% set AREA_START = params.AREA_START|default("75,75") %} # Setup start coordinates for the mesh and give it a default of 75,75
    {% set AREA_END = params.AREA_END|default("125,125") %} # Setup end coordinates for the mesh and give it a default of 125,125
    #The original default values for the Start and End coordinates were both 0,0, which either takes the measured value at 0,0 and uses that value everywhere, or does nothing, i forget
    #75,75 and 125,125 will at least probe a small area close to the middle depending on your size bed. Adjust however you want. 
    M140 S{BED_TEMP} # Start bed heating using the declared or default value
    G28 # Home the printer while we wait on the bed to heat up
    M190 S{BED_TEMP} # Wait for bed to reach temperature
    BED_MESH_CALIBRATE AREA_START={params.AREA_START} AREA_END={params.AREA_END} # Create the mesh
    G90 # Use absolute coordinates
    G1 X1 Y1 F5000; Move to the front left corner
    SET_GCODE_OFFSET Z=0.0 # Reset the G-Code Z offset (adjust Z offset if needed)
    G1 Z5 F3000 # Move the nozzle near the bed    
    G1 Z0.15 F300 # Move the nozzle very close to the bed
    M109 S{EXTRUDER_TEMP} # Set and wait for nozzle to reach temperature

Uncomment any additional lines that you commented out of the existing START_PRINT macro that you want to include and each line is commented so you understand exactly what it is doing.

Leave anything commented out that you do not know what it is doing until you can add your own comments. Additional commands are useful, but not necessary.

Add this to your Start GCode setting in IdeaMaker:

START_PRINT EXTRUDER_TEMP={temperature_extruder1} BED_TEMP={temperature_heatbed} AREA_START={print_pos_min_x},{print_pos_min_y} AREA_END={print_pos_max_x},{print_pos_max_y}

Like I'd said I was able to get past it. I did them all at once tho. I'm guessing based on nothing at all that putting the bed mesh macro before [start_print]. I also commented out the faulty region and split delta z I had set in my [bed_mesh] config section

there are some bugs in macro, i used diferent one, much better ... but still have problem with first layer ... then just turned it of because floating z endstop with bed mesh when it is not complete.... no time to install TAP ... try this one:

https://github.com/Frix-x/klipper-voron-V2/blob/main/macros/calibration/adaptive_bed_mesh.cfg

and i will use this with tap and it have random purge ...

I'll have to check that out once I get a coreXY set up. I'm on an ender 3 so I've been avoiding the nice voron and ratOS resources. I feel like it would take more work to adapt than this was.
If you don't mind be asking, what's buggy about this one?

Hi I think I know the answer but could do with this being confirmed, after installing the macro and the bed mesh being calibrated for the print i now get this when the probe is completed

Move out of range: 203.175 361.000 7.600 [14.000]

This is an Ender 3 S1 Pro with a bed of 220 x 220, why is it calculating a 203 x 361.

thanks

If the bed mesh is completed then the error showup, the problem is more likely from your start gcode. Just my random guess, maybe the G0 or G1 is called when the printer in relative mode. You can try to add G90 line right after bed meah command called.

Question - so I have this working (I think). But wanted a bit of clarity.

If I go into Fluidd/Mainsail "Tune" to view the Mesh, it shows it near a corner and not "in the center of the bed" though I of course watched it probe perfectly in the center of my bed around the "bound" of the print as desired

are the X and Y coordinates correct? that's all that matters, the visual representation will be cut off after the furthest probe points.

Anyone know in superslicer what the custom G code would be? I can't seem to find the right variable:

START_PRINT BED_TEMP=[first_layer_bed_temperature] EXTRUDER_TEMP=[first_layer_temperature] AREA_START=[first_layer_print_min[0]],[first_layer_print_min[1]] AREA_END=[first_layer_print_max[0]],[first_layer_print_max[1]]

doesn't like first_layer_print_min[0] etc.

Hi,
Because you have reference_index, try to change the variable_enable_reference_index : False to variable_enable_reference_index : True

Thank you for your quick help. It works perfectly now!

@rstudner I have this code on start g-code on superslicer:

START_PRINT AREA_START_X={first_layer_print_min[0]} AREA_START_Y={first_layer_print_min[1]} AREA_END_X={first_layer_print_max[0]} AREA_END_Y={first_layer_print_max[1]}

Thanks!

I ended up with this m'self:

START_PRINT BED_TEMP=[first_layer_bed_temperature] EXTRUDER_TEMP=[first_layer_temperature]
AREA_START={first_layer_print_min[0]},{first_layer_print_min[1]} AREA_START={first_layer_print_max[0]},{first_layer_print_max[1]}

please help, I sometimes get an error and I haven't figured out the reason why? the frustrating thing is that it only happens sometimes. although I do understand what the error is saying I don't understand why is happening.
