Update Guide

1. 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.
2. 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 it in case you need it.

New Features

1. Renew the flow rate optimization based on Al LiDAR(K1 Max)

• Deep Learning is introduced to boost the accuracy of flow rate detection.
• Better compatibility with Creality Print, PrusaSlicer, and Orca, and better support of PLA/PETG/ABS and other high-strength filaments.
  
  

2. Add speed options

• The speed options include silent/stable(50%) /standard (100%)/ultrafast (125%).
• Quiet mode configurations:50%printingspeed; 2500mm/s 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

• Ability to adjust the flow rate and Z-offset during printing.
• Ability to calibrate the temperature PID of the nozzle.
• The expert mode is found in“System”.
  
  

4. New ability to exclude failed objects in batch printing

• Enable the“Exclude Objects” in the Creality Print.
• When an individual print fails in batch printing, you can exclude it from printing while not affecting other prints.
  

Optimizations

1. Improve the logic of filament runout detection.
2. Upgrade the control of the chamber cooling fan. Its spin or pause is now controlled by the chamber temperature, instead of default settings.
3. Add Korean as an Ul language.
4. Add filament runout notice to the homepage.

Bug Fixes

1. Fix the frequent Ul crashes and rebooting due to the enabling of object exclusion.
2. Fix the inconsistency between the heated temperature reading on the Web Ul and that on the touch screen.
3. Fix the issue where the Creality Cloud APP could not video-monitor the printing process when the system time fails to sync.
4. Fix the failure to exit the print task because the G-code file name is abnormal.
