v1.0.32

Overview of Changes

• AFC now support's having TD1/TD1s inline with your PTFE tube so that your filament can be scanned for color and Transmission Distance(TD). More information about this new feature can be found on docs site.
• AFC now adds lane data to moonraker's database so that third-parties(eg. slicers) could pull this information. More information about this on docs site.
• Debounce filament sensor bug fixed with latest version of kalico.
• AFC can now auto level during auto home, add auto_level_macro: <macro_name> to AFC.cfg file. More information about this on doc site, search for auto_level_macro on this page.
• Doing a LANE_MOVE with a distance of zero will now not cause klipper to crash.

Overview of Changes

The release fixes the issue's that arise when using Klipper after version v0.13.0-190-g5eb07966 so once updating to this release it's now safe to update Klipper. But beware when updating Klipper in the future as they could keep making updates that break AFC compatibility. This version is compatible with with newest Klipper, Klipper starting at v0.12.0-74-g1d92be71d and Kalico. A check was also added to throw a better warning when pin_tool_start or pin_tool_end are set to Unknown.

Overview of Changes

This release mainly focuses on fixing bugs, but does not address the newest klipper incompatibility so please do not update klipper past version v0.13.0-190. We have been working on a fix for Klipper/Kalico forward and backwards compatibility, just need to do more testing before releasing.

Changes:

• New macro AFC_TEST_LANES has been added, AFC will randomly load and unload selected lanes. See documentation for more info.
• Debounce/delay logic has been add so that noisy sensors can be debounced to prevent false triggers, see documentation for how to enable.
• Issue has been fixed where HTLF would not sync properly with toolhead when lanes 1-3 were loaded and printer/klipper was restarted
• Brush macro has been updated to work with brushes that are on servos

Overview of changes

• Print assist functionality is based off filament usage now, more information about this on the docs site
• Code has been updated to allow for hardware PWM for N20 motors, turning on hardware PWM has show to increase performance in spoolers. To enable this add hardware_pwm: True to all AFC_Stepper sections. You may also notice a difference in how the spoolers work and may be faster, if so you may need to update your fwd_speed_multiplier/rwd_speed_multiplier.
  Note: Boards that are not AFC-lite may not support this depending on if driver pins are connected to hardware capable PWM pins.
• Added statistics tracking, see tracking-toolchange-statistics section on docs page

• Added ability to rewind faster, see SET_LONG_MOVE_SPEED macro
• Quiet mode support added, see quiet-mode section on docs page
• AFC_CUT,POOP,PARK,KICK,WIPE,FORM_TIP can now be toggled while printing and does not require restart, see AFC_TOGGLE_MACRO macro
• Some macros now show up as buttons in your gui's
• Install/update script has been updated to allow user to copy over updated macros into their AFC/macros folder
• Added printout when both sensors in turtleneck are detected to be triggered
• Fixed exclue object bug
• Fixed infinite runout bug with HTLF unit
• Fixed calibration bug where bowden calibration could be a negative number
• Servo support added to AFC_CUT
• Fixed issue in macros where toolhead could smash into poop

Release v1.0.4

DO NOT UPDATE WITH MOONRAKER UPDATE MANAGER WITH THIS RELEASE

To update ssh into your printer and use the following command in your AFC-Klipper-Add-On folder:
./install-afc.sh

Don't forget to restart your printer after updating

Once updated the following should be the version in moonraker update manager and AFC version via console printout:

Moonraker Version: v0.0.0-1360-g1cfb808a
AFC Version in console : v1.0.4-1360-1cfb808

Updates:

• Updates to calibration to have failsafe's so that user does not have to hit estop
• Updates to calibration message's to help guide users when calibration errors out
• Updated calibration to use buffer as tool_pin_start if only tool_pin_end is defined and buffer is also defined

Breaking changes for tip forming, please revisit if you are using tip forming

• Removed multiplying by 60 as that was making tip forming too fast

Additions

• Added virtual bypass sensor, AFC adds this sensor if hardware bypass is not detected. State is retained between restarts. More information about it here
• Added default temperature value to default_material_temps list instead of using min_temp_val + 5 ( need to manually add default, see example )
• Added braking to n20 when stopping them. This was advised to implement from Isiks Tech to hopefully help reduce back feeding from motors into MCU board when in coast mode
• Added PURGE_LENGTH variable when doing filament changes see doc
• Added assisted unload, When enabled, the retracts out of the toolhead before the long, fast move back through the bowden tube is assisted. This helps with full spools where even a retract of a few centimeters can cause a loop to fall off the spool. Enabled by default see doc for more info
• Added logging of delta time and total time for how long tool changes take(more times can be found on AFC.log file), don't be afraid to share your toolchange time with us
• Added ability to change tool_stn/tool_stn_unload/tool_sensor_after_extruder without restarting. Macro, save to config macro
• Added ability to turn off/on AFC LEDs, this will not turn off LEDs controlled outside of AFC
• Added ability to manually set and
  unset lanes that are loaded in toolhead
• Added check for printing for LANE_MOVE, HUB_LOAD and LANE_UNLOAD macros
• Added more guidance to error messages when errors happen during TOOL_LOAD and TOOL_UNLOAD
• Added debounce logic when triggering prep sensor so that it does not run more than once
• Added variable speed to LANE_MOVE move, run faster for distance over 200
• Added printout when trying to load and load sensor is already triggered
• Added more printout to let user know when calibration is done
• Added printout when trying to unload but no lane is loaded
• Updated error print out messages when loading/unloading
• Added 1 second time debounce to prep callback
• Added checking to make sure lane was not none in CHANGE_TOOL
• Added pauses in some places if printer is currently in a print
• Changed print message in runout pause to display as error so it pauses correctly and saves position
• Added AFC logger so all AFC messages now get logged to AFC.log in same place of users klippy.log
• Added check to make sure buffer configured as belay is not configure for extruder tool_pin_start
• Improved Prompts for better user experience
• Added error checking to infinite spool rollover, before if a error happened during unload it could keep running the print
• Added lane ejection when unload on runout is set when runouts are detected and a lane is not set for rollover
• Reworked rollover logic to restore position after lane has been ejected fully so that nozzle does not sit on part while ejecting spool
• Added error messages to AFC status so errors would show up in AFC integration panel

Fixes

• Fixed error in CHANGE_TOOL where change logic was being triggered if change was in a comment on the same line
• Fixed issue where position would not be restored back to the correct position after a lane change/pause/resume, and could cause crashes into purge tower
• Fixed issue where getting spoolman data would error out when server variable in moonraker ended in a slash
• Fixed issue where prep would no longer activate extruder motors when user rapidely triggered prep sensor
• Fixed error in CHANGE_TOOL where change logic was being triggered if change was in a comment on the same line
• Fixed issue where filament was not unloading correctly when only tool_pin_end is only defined
• Fixed issue where prep logic would try to unload forever if only tool_pin_end was defined
• Fixed error where user could put wrong lane for rollover and it would not error until runout logic is triggered
• Fixed issue where passing in +-<number> for length when calling SET_BOWDEN_LENGTH would crash klipper

New Macros, review them all here

• Added SET_SPEED_MULTIPLIER macro to allow user to change fwd/rwd speed multipliers during prints
• Added SAVE_SPEED_MULTIPLIER macro to save updated multiplier to config file for specified lane
• Added AFC_RESET which will open a prompt to select a lane to reset to hub
• Added AFC_LANE_RESET, AFC_RESET calls this
  • Can be used as follows: LANE_RESET LANE=lane1 DISTANCE=500. This will move the lane by the
    distance and then reset to hub if not reached
• Added SET_HUB_DIST macro to set distance between extruder and hub for a lane
• Added SAVE_HUB_DIST macro to save dist_hub for a lane

New config variables

• Added afc_unload_bowden_length parameter, updated set_bowden_length macro to be able to adjust unload value as well
• Added default_material_type variable to assign to spool when loaded into lane. Manually review config
• Added pause_when_bypass_active variable to pause print if bypass is active, defaults to false
• Added unload_on_runout variable to unload lane when runout happens and another lane is not setup to change to, default to false.
  Found in AFC config
• Added assisted unload, When enabled, the retracts out of the toolhead before the long, fast move back throught the bowden tube is assisted.
  This helps with full spools where even a retract of a few centimeters can cause a loop to fall off the spool.
  Enabled by setting assisted_unload: True in AFC.cfg. see doc for more info
