 There are mainly the following 5 types of filling:

a) One-way filling: The filling line is always filled from left to right.

b) Two-way filling: The filling line first fills from left to right, then fills from right to left, and the rest is filled cyclically.

c) Circular filling: The filling line is the circular offset filling of the object outline from the outside to the inside.

d) Optimized two-way filling: Similar to two-way filling, but there will be connecting lines between the ends of the filling lines.

e) Optimized bow fill: Similar to bow fill, it will still jump to fill in the blank areas of the object.

The above 5 filling types can be switched by clicking the button with the mouse, and can be set or changed conveniently and quickly according to the actual needs.

 Optimized two-way filling: The marking efficiency is the highest, but sometimes there will be problems such as connection lines and unevenness.

 Two-way filling: The marking efficiency is the second, and the effect is good.

 One-way filling: the slowest marking efficiency, rarely used in actual processing.

 Ring filling: only used when marking fine graphics or fonts.

The specific method used depends on factors such as the material of the workpiece to be marked, the effect to be marked, and the requirements for the marking speed.
