1. add 'main menu -> multoo -> enable abl'

Automatic leveling can be turned off. Set up needs to be performed,

a. main menu-> multoo-> confirm settings

b. Restart the machine.

It is recommended not to turn this option off.

2. add 'main menu -> multoo -> fade height'

The meaning of this value is,

The data obtained by automatic leveling are based on the flatness of the platform. Assuming this value is 10, the upper surface of the model will be parallel to the X axis after the Z axis is raised to 10 mm, and no longer parallel to the platform.

In previous firmware versions, the default setting for this value was 10. Now setting options have been added to the menu.

3. When SD card printing is paused,

The motor will remain in position. And locked up.

In previous firmware versions, there was a timeout. When the timeout occurs, the motor is unlocked.
