The "Scanning path for engraving" refers to the path settings that determine in what order and by what means the laser module scans and engraves the objects during the processing. Different choices of paths will affect the processing time and specific operational procedures.
How does it work?
When you select User Defining mode as the processing path, you can freely set the Scanning path for engravingas needed. There are two scanning paths for you to choose from, that is One by one and All together.
All together
Engraves multiple objects at the same time in the set sequence and direction. The laser module travels a longer distance since it needs to travel across the empty space between each object over and over again. Therefore, the processing time is usually longer.
For engraving vectors with the same processing parameters, the laser module scans from top to bottom and from left to right. When there are left and right juxtaposed parts between the pictures, they will be processed successively in one scan of the laser module.
Note: If engraving ≥ 2 vectors in the current canvas and the parameters between them are not exactly the same: 1. Grouped by parameters, vectors with the same parameters are grouped into one group. A total of ≥2 groups are generated, and there are ≥1 engraved vectors in each group. 2. The sequence rule between groups is: use the Y coordinate value of the vector with the smallest Y value in the group as the Y value of the group, and the group with the smallest Y value will be processed first. 3. Sort the processing path according to the Y value of each group.
Note: Bitmaps are processed using the same rules.
One by one
Engraves objects one by one in the set sequence and direction. The laser module travels a shorter distance since it can finish engraving one object before moving to the next. Therefore, the processing time is usually shorter.
Note: When engraving multiple objects, greedy strategy is adopted. That is, after engraving the current object, find the next object in the nearest position and start engraving. When engraving any vector and bitmap object, processing always starts from the upper left corner, scans from left to right, from top to bottom, and ends at the lower right corner. After engraving the last object, the laser module is at the lower right corner of the object, find the distance between this position and the upper left corner of other objects to be processed, and take the object with the shortest distance as the next object to be processed.
How to Use it？
When All together is selected, the scanning paths for objects with different parameters will be shown as below.
For example:
(1) Engrave 6 vectors in the current canvas. Objects with the same parameters are grouped into one group. A total of 3 groups (Group1,2,3) are generated, each group contains 2 vectors.
(2) Among the three groups, Group 2 has the smallest Y coordinate value, so it is processed first, followed by Group 3 and finally Group 1.
When One by one is selected, the scanning paths for objects with different parameters will be shown as below.
For example:
(1) Engrave 3 vectors in the current canvas, A,B,C respectively.
(2) When engraving, the processing always starts from the upper left corner, that is, from A in this canvas. After engraving A, the laser module starts from the lower right corner of A to find the nearest object, that is, B, as the next processing object. Finally, process C.
