10.2 Marking Parameter Base

EzCad2UNI User’s Manual

Marking Parameter Base is a base filled with all marking parameters which have been set by

users already.

YAG: YAG indicates that the current Marking Parameter is for YAG laser machine, and if not,

it is for CO2 laser machine.

Select param from library: When press this button, a dialog will pop up as figure 10.2-1

shows. We can save the parameters to disk files, or to delete parameters from files.

Loop count: loop times to mark an object

Speed: the current marking speed

Power / Current: In CO2 mode, this item indicates the power percentage of the current

marking parameter, and 100% refers to the biggest power of the laser equipment. In YAG mode,

this item indicates the current of the Q-switch.

Frequency: the laser machine’s frequency in the marking parameter

Q pulse Width: the high-level’s time of the Q pulse if the laser equipment is Q-switch YAG

laser machine

Start TC: When the scanhead has to execute a mark command, the scanner mirrors first have

to be accelerated up to the defined marking speed. In the beginning of the movement, the laser

focus moves very slowly which may result to burn-in effect at the start point. To avoid this, We

insert a delay (Start TC) at the beginning of each mark command. When the laser eventually turns

on, the mirrors have already reached a certain velocity. However, if this value is too large, the first

part of the vector will be cut off. Also negative value is supported.

Laser Off TC: The delay time of the laser shutting down after marking finished. Proper time

can wipe off the burn-in effect at the end. This value cannot be negative.

End TC: The End TC parameter is used to control how long the software will wait at the

end of a series of vectors. The wait is required because the software is always "ahead" of the

hardware and must wait for the hardware to catch up. This delay applies to the end of all vectors

in which the laser is to be turned off after execution.

Polygon TC: the Polygon TC parameter is used to control how long the software will wait

at vector connection points. The wait is required due to the lag time between the software/DAC

position and the actual hardware/mirror position. This timer applies to all vectors whose endpoint

is also the start point of the next vector (polygon connection points). In other words, this timer

applies to end of all vectors in a series of connected vectors, except for the last one (the end of last

one is controlled by the End TC parameter). The three connected points in a square or the

intermediate connection points in a polyline circle are examples of points the Polygon TC

parameter can effect. The starting point of the square is controlled by Start TC parameter. The

last corner of the square is controlled with the End TC timer.

Clicking “Advanced” will prompt an advanced parameter dialog box as Figure 10-5 shows.
