This document covers recent software changes to the config file that are not backwards compatible. It is a good idea to review this document when upgrading the Klipper software.
All dates in this document are approximate.
Changes
20200109: The bed_mesh module now references the probe's location
in for the mesh configuration. As such, some configuration options
have been renamed to more accurately reflect their intended
functionality. For rectangular beds, min_point and max_point
have been renamed to mesh_min and mesh_max respectively. For
round beds, bed_radius has been renamed to mesh_radius. A new
mesh_origin option has also been added for round beds. Note that
these changes are also incompatible with previously saved mesh profiles.
If an incompatible profile is detected it will be ignored and scheduled
for removal. The removal process can be completed by issuing the
SAVE_CONFIG command. The user will need to re-calibrate each profile.
20191218: The display config section no longer supports "lcd_type: st7567". Use the "uc1701" display type instead - set "lcd_type: uc1701" and change the "rs_pin: some_pin" to "rst_pin: some_pin". It may also be necessary to add a "contrast: 60" config setting.
20191210: The builtin T0, T1, T2, ... commands have been removed. The extruder activate_gcode and deactivate_gcode config options have been removed. If these commands (and scripts) are needed then define individual [gcode_macro T0] style macros that call the ACTIVATE_EXTRUDER command. See the config/sample-idex.cfg and sample-multi-extruder.cfg files for examples.
20191210: Support for the M206 command has been removed. Replace with calls to SET_GCODE_OFFSET. If support for M206 is needed, add a [gcode_macro M206] config section that calls SET_GCODE_OFFSET. (For example "SET_GCODE_OFFSET Z=-{params.Z}".)
20191202: Support for the undocumented "S" parameter of the "G4" command has been removed. Replace any occurrences of S with the standard "P" parameter (the delay specified in milliseconds).
20191126: The USB names have changed on micro-controllers with native USB support. They now use a unique chip id by default (where available). If an "mcu" config section uses a "serial" setting that starts with "/dev/serial/by-id/" then it may be necessary to update the config. Run "ls /dev/serial/by-id/*" in an ssh terminal to determine the new id.
20191121: The pressure_advance_lookahead_time parameter has been removed. See example.cfg for alternate configuration settings.
20191112: The tmc stepper driver virtual enable capability is now automatically enabled if the stepper does not have a dedicated stepper enable pin. Remove references to tmcXXXX:virtual_enable from the config. The ability to control multiple pins in the stepper enable_pin config has been removed. If multiple pins are needed then use a multi_pin config section.
20191107: The primary extruder config section must be specified as "extruder" and may no longer be specified as "extruder0". Gcode command templates that query the extruder status are now accessed via "{printer.extruder}".
20191021: Klipper v0.8.0 released
20191003: The move_to_previous option in [safe_z_homing] now defaults to False. (It was effectively False prior to 20190918.)
20190918: The zhop option in [safe_z_homing] is always re-applied after Z axis homing completed. This might need users to update custom scripts based on this module.
20190806: The SET_NEOPIXEL command has been renamed to SET_LED.
20190726: The mcp4728 digital-to-analog code has changed. The default i2c_address is now 0x60 and the voltage reference is now relative to the mcp4728's internal 2.048 volt reference.
20190710: The z_hop option was removed from the [firmware_retract] config section. The z_hop support was incomplete and could cause incorrect behavior with several common slicers.
20190710: The optional parameters of the PROBE_ACCURACY command have changed. It may be necessary to update any macros or scripts that use that command.
20190628: All configuration options have been removed from the [skew_correction] section. Configuration for skew_correction is now done via the SET_SKEW gcode. See skew_correction.md for recommended usage.
20190607: The "variable_X" parameters of gcode_macro (along with the VALUE parameter of SET_GCODE_VARIABLE) are now parsed as Python literals. If a value needs to be assigned a string then wrap the value in quotes so that it is evaluated as a string.
20190606: The "samples", "samples_result", and "sample_retract_dist" config options have been moved to the "probe" config section. These options are no longer supported in the "delta_calibrate", "bed_tilt", "bed_mesh", "screws_tilt_adjust", "z_tilt", or "quad_gantry_level" config sections.
20190528: The magic "status" variable in gcode_macro template evaluation has been renamed to "printer".
20190520: The SET_GCODE_OFFSET command has changed; update any g-code macros accordingly. The command will no longer apply the requested offset to the next G1 command. The old behavior may be approximated by using the new "MOVE=1" parameter.
20190404: The Python host software packages were updated. Users will need to rerun the ~/klipper/scripts/install-octopi.sh script (or otherwise upgrade the python dependencies if not using a standard OctoPi installation).
20190404: The i2c_bus and spi_bus parameters (in various config sections) now take a bus name instead of a number.
20190404: The sx1509 config parameters have changed. The 'address' parameter is now 'i2c_address' and it must be specified as a decimal number. Where 0x3E was previously used, specify 62.
20190328: The min_speed value in [temperature_fan] config will now be respected and the fan will always run at this speed or higher in PID mode.
20190322: The default value for "driver_HEND" in [tmc2660] config sections was changed from 6 to 3. The "driver_VSENSE" field was removed (it is now automatically calculated from run_current).
20190310: The [controller_fan] config section now always takes a name (such as [controller_fan my_controller_fan]).
20190308: The "driver_BLANK_TIME_SELECT" field in [tmc2130] and [tmc2208] config sections has been renamed to "driver_TBL".
20190308: The [tmc2660] config section has changed. A new sense_resistor config parameter must now be provided. The meaning of several of the driver_XXX parameters has changed.
20190228: Users of SPI or I2C on SAMD21 boards must now specify the bus pins via a [samd_sercom] config section.
20190224: The bed_shape option has been removed from bed_mesh. The radius option has been renamed to bed_radius. Users with round beds should supply the bed_radius and round_probe_count options.
20190107: The i2c_address parameter in the mcp4451 config section changed. This is a common setting on Smoothieboards. The new value is half the old value (88 should be changed to 44, and 90 should be changed to 45).
20181220: Klipper v0.7.0 released
