Laser PolyDelay
A polygon delay is a delay automatically inserted between two marking segments. The minimum delay allows enough time for the galvos and mirror to “catch-up” with the command signal before a new command is issued to move on to the next point.
If variable polygon delay mode is selected, then the delay is variable and changes as a function as to how large an angular change is required to move on to the next point. The larger the angular change, the longer it takes for the galvos to change direction and accelerate to the required speed in the new direction. The delay is scaled proportionally to the size of the angle.
Syntax
| PolyDelay = int value (Polygon delay in microseconds) |
--This program demonstrates how the global settings of a laser works. User can change the parameters and observe the marking quality of a rectangle. This program will also display the Marking time.
