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
|
|
|
|
20191121: The USB name has changed on lpc176x. It now uses the unique
|
|
chip id by default. Update the "serial" setting in the "mcu" config
|
|
section accordingly.
|
|
|
|
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
|
