Remind:
If the leveling fails or the homing fails, please try to restart the power or choose to
restore the factory settings in the settings.
The leveling grid data will be cleared after a factory reset and must be re-leveled.
Leveling Temperature Recommendations:
Hot end temperature: 0 ℃
(in order to avoid fan rotation and temperature affecting the leveling accuracy)
Hot bed temperature:
the temperature required by the filament +5 °C
(To avoid the leveling effect due to the thermal deformation of the hot bed)
Board firmware
Update log：
20220616：
- Added the setting item of leveling temperature. You can customize the leveling
temperature in the Settings.
Reminder: At present, the Z-offset value set during printing will not be saved to
EEPROM (Z-offset data will be lost after power off or power failure, and Z-offset
needs to be adjusted again when printing next time).
Solution: You can save the EEPROM by heading to 【Settings】→【Temperature】
→【Leveling Temperature】, clicking 【Save】in the upper right corner of after
printing is ‘completed or canceled’, so that the set Z-offset will be saved to the
EEPROM.
20220711:
- Improved leveling method.
20220816:
- Fixed some discovered bugs. Optimize the leveling speed and return to the origin
speed.
- During the printing process, click 【Pause】or "Break Detection" to detect a break
in the filament, the extruder will pump back 6mm to avoid the filament leakage issue
after the pause. At the same time, when you click 【Resume】after the pause, the
extruder will advance 6mm in the original printing position, so if you replace the
filament, please do not insert it directly into the nozzle position.

- To solve the problem that the Z-offset adjusted during printing will not be saved：
During printing, click 【stop】→【confirm】or click 【confirm】after printing is
completed, the Z-offset value will be saved automatically.
