¶ Update Guide
-
Store the firmware in a USB drive, and plug the USB drive into the printer for update. After the update is done, please enter “Settings - Self-check”, tick "Input Shaping" and "Auto Bed Leveling", and start self-check. Then, wait for the self-check to complete before using the printer.
-
If the Fluidd/Mainsail has been installed, the update will not delete it but will overwrite its configurations. Please save the configuration file before updating in case you need it.
¶ New Features
¶ 1. Renew the flow rate optimization based on AI LiDAR (K1 Max)
a. Deep Learning is introduced to boost the accuracy of flow rate detection.
b. Better compatibility with Creality Print, PrusaSlicer and Orca, and better support of PLA/PETG/ABS and other high-strength filaments.
c. Flow rate test lines are made longer for a more accurate result.
¶ 2. Add Speed Options
a. The speed options include silent/stable (50%)/standard (100%)/ultrafast (125%).
b. Silent mode configurations: 50% printing speed; 2500mm/s² upper limit of acceleration and deceleration; 150mm/s upper limit of printing speed; 50% speed of part cooling fan and auxiliary fan.
Note: You can only switch mode while printing. There will be a short pause when switching the mode.
¶ 3. Support Expert Mode
a. Ability to adjust the flow rate and Z-offset during printing.
b. Ability to calibrate the temperature PID of the nozzle.
c. The expert mode is found in “System”.
¶ 4. New Ability to Exclude Failed Print in Batch
a. Enable the “excluding object” in the Creality Print.
b. When an individual print fails in batch printing, you can exclude it from printing while not affecting other prints.
¶ Optimizations
- Improve the logic of filament runout detection.
- Upgrade the control of the chamber cooling fan. Its spin or pause is now controlled by the chamber temperature, instead of default settings.
- Add Korean as a UI language.
- Add filament runout notice to the homepage.
¶ Bug Fixes
- Fix the frequent UI crashes and rebooting due to the enabling of object exclusion.
- Fix the inconsistency between the heatbed temperature reading on the Web UI and that on the touch screen.
- Fix the issue where the Creality Cloud APP could not video-monitor the printing process when the system time fails to sync.
- Fix the failure to exit the print task because the G-code file name is abnormal.
