Example configurations This document contains guidelines for contributing an example Klipper configuration to the Klipper github repository (located in the config directory). VALUE|default('')|string|lower %} Set global variables? Is it possible to have a global variable set in for example a PLA. Be very careful, however, as an overly broad SEARCH parameter can take a long time to process and potentially hang or crash klipper. This collection includes macros for print management, filament handling, calibration, and utility functions specifically tailored for the Sovol SV08 printer. List of interesting macros View the Project on GitHub Macro variables usage Set variables with default value and gcode that does nothing Writing Klipper Macros The following guide is my attempt at explaining how Klipper 1 macros work and how write macros. How it works [gcode_macro START_PRINT] gcode: END_PRINT STEP 2: New code for Klipper (Macro. You can technically forgo the parameter setup section entirely and just pass the parameters directly (for example M190 S{params. log when I issue the "SET_GCODE_VARIABLE MACRO=TRV VARIABLE=test_cycle VALUE A collection of my Klipper G-code macros. Error evaluating 'gcode_macro bed_mesh_calibrate_fast:gcode': jinja2. However, there are also some nice extras: # All customizations are documented in globals. It’s a preference, but I think it’s better practice to do it this way. to prepare the print, heat up the system etc. Then you can use it in your macros like so: SAVE_VARIABLE VARIABLE=temperature_target VALUE={TARGET_TEMP} This tells it to save the value of TARGET_TEMP to the variables. Just copy a variable from This document is a reference for options available in the Klipper config file. Ellis’ Print Tuning Guide This dumps all current Klipper variables to the g-code terminal. cfg file under the name temperature_target. Otherwise it will default to 110. com Macro. NAME|default('')|string|lower %} {% set filter_value = params. Contribute to Desuuuu/klipper-macros development by creating an account on GitHub. g. I've noticed that SET_GCODE_VARIABLE fails when used with strings. Klipper macros use Jinja2 templates for dynamic command generation, enabling conditional logic, variable manipulation, and integration with the printer's state. You can simply use the macro name to call it so that it excites a series of pre-build commands. cfg. It’s mostly based on my knowledge from reading the Klipper documentation, experimentation, and information from the Klipper Discord. Contribute to stablestud/klipper-config development by creating an account on GitHub. You can set up persistent/global variables, but that’s another topic. Additional information are also included in the official documentation. cfg file and use the variable in some of my macros? I know I can set local variables, but couldn't figure if global is possible. Advanced Klipper macros tend to rely extensively on monkey patching, which can lead to problems with unusual configurations or when mixing macros from various sources. Contribute to Klipper3d/klipper development by creating an account on GitHub. Personal Klipper configuration for my 3D printer. This is done by creating a file in which the variables are written. I get the "internal error" error leading the M112 shutdown and syntax error in klippy. . If the value of the variable is changed at a later time, the new value will persist until changed again. The Macros The sample-macros. Commands templates This document provides information on implementing G-Code command sequences in gcode_macro (and similar) config sections. Note: The shell scripts for shaper Via the Klipper macro system such variables can be passed into Klipper, e. cfg and printer. These variables are discarded once the macro finishes. Via the Klipper macro system such variables can be passed into Klipper, e. in this example we are creating a local variable called TARGET_TEMP that only exists within the macro. {% set filter_name = params. This is useful for debugging macros by allowing you to probe printer state. Running things from Mainsail Connect to your printer, then look in the Macros section for our newly minted macro, named BACKUP CFG Click on the BACKUP CFG button and the console will report the output from the command: You can click this button manually any time you want to create a backup Editing files on GitHub and updating your printer After uploading the file to print I get the following error. Case is not important for the G-Code macro name - MY_MACRO andmy_macro will evaluate the same and may be called in either upper orlower case. Take the following example: [gcode_macro TEST] variable_v: '' gcode: SET_GCODE_VARIABLE MACRO=TEST VARIABLE=v VALUE='value' Calling the above macro will result in the fol You really should avoid custom macros like this until you're comfortable using Klipper with a basic config. Jun 22, 2024 · Macros can be executed by Klipper in response to specific triggers; below are examples of common triggers: Think of this as calling the macro by name. By leveraging Jinja2 templates, user-defined variables, and access to the printer state, macros can automate complex operations and implement custom behaviors. mergely. BED|int}). The provided VALUE is parsed as a Python literal. Note that the Klipper Community Discourse server is also a useful resource for finding and sharing config files. Guidelines Select the appropriate config filename prefix: The printer prefix is used for stock printers sold SET_GCODE_VARIABLE MACRO=<macro_name> VARIABLE=<name> VALUE=<value>: This command allows one to change the value of a gcode_macro variable at run-time. check_klipper_config_path: True # By default Moonraker will validate that Klipper's configuration file exists # within the data path's "config" folder, as this is a requirement for # Moonraker to write to the configuration.
