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.


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/ 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
