History of Klipper releases. Please see
[installation](Installation.md) for information on installing Klipper.
Klipper 0.7.0
=============
Available on 20181220. Major changes in this release:
* Klipper now supports "mesh" bed leveling
* New support for "enhanced" delta calibration (calibrates print x/y
dimensions on delta printers)
* Support for run-time configuration of Trinamic stepper motor drivers
(tmc2130, tmc2208, tmc2660)
* Improved temperature sensor support: MAX6675, MAX31855, MAX31856,
MAX31865, custom thermistors, common pt100 style sensors
* Several new modules: temperature_fan, sx1509, force_move, mcp4451,
z_tilt, quad_gantry_level, endstop_phase, bltouch
* Several new commands added: SAVE_CONFIG, SET_PRESSURE_ADVANCE,
SET_GCODE_OFFSET, SET_VELOCITY_LIMIT, STEPPER_BUZZ, TURN_OFF_HEATERS,
M204, custom g-code macros
* Expanded LCD display support:
* Support for run-time menus
* New display icons
* Support for "uc1701" and "ssd1306" displays
* Additional micro-controller support:
* Klipper ported to: LPC176x (Smoothieboards), SAM4E8E (Duet2),
SAMD21 (Arduino Zero), STM32F103 ("Blue pill" devices), atmega32u4
* New Generic USB CDC driver implemented on AVR, LPC176x, SAMD21, and
STM32F103
* Performance improvements on ARM processors
* The kinematics code was rewritten to use an "iterative solver"
* New automatic test cases for the Klipper host software
* Many new example config files for common off-the-shelf printers
* Documentation updates for bootloaders, benchmarking,
micro-controller porting, config checks, pin mapping, slicer
settings, packaging, and more
* Several bug fixes and code cleanups
Klipper 0.6.0
=============
Available on 20180331. Major changes in this release:
* Enhanced heater and thermistor hardware failure checks
* Support for Z probes
* Initial support for automatic parameter calibration on deltas (via a
new delta_calibrate command)
* Initial support for bed tilt compensation (via bed_tilt_calibrate
command)
* Initial support for "safe homing" and homing overrides
* Initial support for displaying status on RepRapDiscount style 2004
and 12864 displays
* New multi-extruder improvements:
* Support for shared heaters
* Initial support for dual carriages
* Support for configuring multiple steppers per axis (eg, dual Z)
* Support for custom digital and pwm output pins (with a new SET_PIN command)
* Initial support for a "virtual sdcard" that allows printing directly
from Klipper (helps on machines too slow to run OctoPrint well)
* Support for setting different arm lengths on each tower of a delta
* Support for G-Code M220/M221 commands (speed factor override /
extrude factor override)
* Several documentation updates:
* Many new example config files for common off-the-shelf printers
* New multiple MCU config example
* New bltouch sensor config example
* New FAQ, config check, and G-Code documents
* Initial support for continuous integration testing on all github commits
* Several bug fixes and code cleanups
Klipper 0.5.0
=============
Available on 20171025. Major changes in this release:
* Support for printers with multiple extruders.
* Initial support for running on the Beaglebone PRU. Initial support
for the Replicape board.
* Initial support for running the micro-controller code in a real-time
Linux process.
* Support for multiple micro-controllers. (For example, one could
control an extruder with one micro-controller and the rest of the
printer with another.) Software clock synchronization is implemented
to coordinate actions between micro-controllers.
* Stepper performance improvements (20Mhz AVRs up to 189K steps per
second).
* Support for controlling servos and support for defining nozzle
cooling fans.
* Several bug fixes and code cleanups
Klipper 0.4.0
=============
Available on 20170503. Major changes in this release:
* Improved installation on Raspberry Pi machines. Most of the install
is now scripted.
* Support for corexy kinematics
* Documentation updates: New Kinematics document, new Pressure Advance
tuning guide, new example config files, and more
* Stepper performance improvements (20Mhz AVRs over 175K steps per
second, Arduino Due over 460K)
* Support for automatic micro-controller resets. Support for resets
via toggling USB power on Raspberry Pi.
* The pressure advance algorithm now works with look-ahead to reduce
pressure changes during cornering.
* Support for limiting the top speed of short zigzag moves
* Support for AD595 sensors
* Several bug fixes and code cleanups
Klipper 0.3.0
=============
Available on 20161223. Major changes in this release:
* Improved documentation
* Support for robots with delta kinematics
* Support for Arduino Due micro-controller (ARM cortex-M3)
* Support for USB based AVR micro-controllers
* Support for "pressure advance" algorithm - it reduces ooze during
prints.
* New "stepper phased based endstop" feature - enables higher
precision on endstop homing.
* Support for "extended g-code" commands such as "help", "restart",
and "status".
* Support for reloading the Klipper config and restarting the host
software by issuing a "restart" command from the terminal.
* Stepper performance improvements (20Mhz AVRs up to 158K steps per
second).
* Improved error reporting. Most errors now shown via the terminal
along with help on how to resolve.
* Several bug fixes and code cleanups
Klipper 0.2.0
=============
Initial release of Klipper. Available on 20160525. Major features
available in the initial release include:
