Klipper v0.7.0 release

[KevinOConnor]

This issue is a notice of my intent to make the next Klipper release (v0.7.0). My rough plan is to make the release around mid December (~20181214), with a feature freeze starting the end of this month (~20181130).

If anyone is actively developing a new feature and would like it to be included in the next release, please let me know within the week. (Use a separate github issue or github pull-request to do that.) After the feature freeze, the Klipper master branch will focus on bug fixes and documentation updates.

The following is my draft list of new features added since the last release (v0.6.0):

• Support for "bed mesh" leveling
• Support for enhanced delta calibration (calibrates print x/y dimensions on delta printers)
• Support for run-time configuration of Trinamic stepper 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
• 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 type display support:
  • Support for run-time menus
  • New display icons
  • Support for "uc1701" type displays
• Additional micro-controller support:
  • Klipper ported to: LPC176x (Smoothieboards), SAM4E8E (Duet2), SAMD21 (Arduino Zero), STM32F103 ("Blue pill" devices)
  • New Generic USB CDC driver implemented on AVR, LPC176x, SAMD21, and STM32F103
  • Significant 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 documentation updates, bug fixes, and code cleanups

If you have an issue or code update, please create a separate github issue or github pull-request with the pertinent information.

Really looking forward to the bed mesh leveling! I'll be making the switch once it's there to deal with my slightly domed PEI surface.

It’s a great project Kevin.

Thanks very much for your efforts - really getting a lot of attention among our user group.

Do you have a roadmap for Klipper to come out of Beta? Any timeline for a version 1.0? Amazing work Kevin, I really love Klipper, and thank you for making it available to all of us!!

I think that it is necessary to add this https://github.com/KevinOConnor/klipper/issues/773#issuecomment-431595545 solution to the faq, it helped me, but it was difficult to find it.

Thanks everyone.

@LazaroFilm - I think Klipper has sufficient functionality to be considered post-beta, and I think Klipper is stable enough to be considered post-beta. However, I feel the Klipper config file has not been particularly stable - we've been making changes to the config as we gather feedback. I suspect this will continue for the immediate short-term. Alas, I don't have a timeframe for hardening the config.

@pamalofeev - understood. To the best of my knowledge, that issue only occurs on lower powered host machines that aren't recommended (eg, an rpi1). I have a rough plan to fix the underlying issue after the Klipper v0.7.0 release. So, my preference right now is to not officially document the workaround, but to instead fix the issue in the next couple of months.

Thanks again, -Kevin
