- This Klipper macro will create a bed mesh based on the size of your print.
Complete credit goes to ChipCE (https://gist.github.com/ChipCE/95fdbd3c2f3a064397f9610f915f7d02) for the idea and sample code. I completely rewrote the macro to be more dynamic and for some added features.
- Reusable Bed Mesh - bed mesh will be reused if print area is smaller or equal to the previous one with ability to override
- Easy To Add - Nothing to update in the script since the existing bltouch or probe offsets, existing bed_mesh min/max, probe_count values are used from printer.cfg
- Seamless Bed Mesh Calibration - BED_MESH_CALIBRATE replaced with new script
- Separate axis probe counts - if print area X or y is 50% than available area, probe_count for that axis is changed from the default to 3
- Supports Bed Mesh Relative Reference Index - if "relative_reference_index" is set in bed_mesh, it will be reconfigured to use the middle point on the bed
- Klicky Probe Compatible - Works with Klicky Probe on Voron
This is currently in development. While it works on my 2 printers, it's impossible to account for everyone's various config. When first implementing this, be prepared to click the "Emergency Stop" button if it tries to probe off the bed.
- Combined klicky probe version with regular script
- Added 20mm buffer to bed mesh
- Fixed issue with bed mesh being skipped when current bed mesh is cleared
- Fixed issue with offset expanding bed mesh area out of bounds
SSH into the Pi and run the following commands:
cd ~ git clone https://github.com/Turge08/print_area_bed_mesh.git ~/print_area_bed_mesh/install.sh
Through Fluidd/Mainsail, edit printer.cfg file and add the following line at the top of your printer.cfg:
[include print_area_bed_mesh.cfg]
From Fluidd/Mainsail, edit moonraker.conf (in the same folder as your printer.cfg file) and add:
[update_manager print_area_bed_mesh] type: git_repo path: ~/print_area_bed_mesh origin: https://github.com/Turge08/print_area_bed_mesh.git is_system_service: False
NOTE: You must perform step #1 at least once or Moonraker will generate an error.
- Where you normally perform a BED_MESH_CALIBRATE in your start_print macro, replace it (or add it if you didn't previously have it) with the following line:
BED_MESH_CALIBRATE PRINT_MIN={params.PRINT_MIN} PRINT_MAX={params.PRINT_MAX}
- If you want to force a new mesh every time, use the following syntax:
BED_MESH_CALIBRATE PRINT_MIN={params.PRINT_MIN} PRINT_MAX={params.PRINT_MAX} FORCE_NEW_MESH=True
- Modify your printer's start g-code in your slicer to include the PRINT_MIN and PRINT_MAX parameters:
Examples:
- PrusaSlicer/SuperSlicer:
print_start EXTRUDER={first_layer_temperature[initial_extruder] + extruder_temperature_offset[initial_extruder]} BED=[first_layer_bed_temperature] CHAMBER=[chamber_temperature] PRINT_MIN={first_layer_print_min[0]},{first_layer_print_min[1]} PRINT_MAX={first_layer_print_max[0]},{first_layer_print_max[1]}
- Cura (add this to your start gcode at the end of the start_print command:)
PRINT_MIN=%MINX%,%MINY% PRINT_MAX=%MAXX%,%MAXY%
*(Cura slicer plugin) To make the macro to work in Cura slicer, you need to install the post process plugin by frankbags - 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 and select Mesh Print Size
Examples:
-
PrusaSlicer/SuperSlicer:
BED_MESH_CALIBRATE PRINT_MIN={first_layer_print_min[0]},{first_layer_print_min[1]} PRINT_MAX={first_layer_print_max[0]},{first_layer_print_max[1]} -
