GRAPHICS SOFTWARE SETUP

Section 3-19

The wizard will ask you to focus the laser

system to the material using the Focus

Tool and to place the left side of the

material at the 4-inch mark, up against

the top ruler. It will then ask you to enter

the Power and Speed settings that you

would normally use to engrave this

particular material at 100% speed. After entering the appropriate values and clicking Next, the wizard

will send a test file to the laser system. Be sure to turn on your exhaust system when you engrave

the file. After the files completes, remove the material and examine it closely or with a magnifying

glass. Choose the appropriate letter that is above the straightest appearing line. To help you, the

lines are composed of two segments that are slightly overlapping each other approximately 10%.

Enter this value into the driver.

Once the Mechanical Tuning Test is completed the wizard will terminate. To keep the laser system

running at its best, be sure to periodically run the mechanical tuning wizard every 3 – 6 months of

operation or as necessary. A sign that the system needs tuning would be that text characters may

appear “fuzzy” or “double imaged” when engraving at high speeds.

NOTE: If your system has a many hours or years of operation and your motion system components

are extremely worn, the mechanical tuning test sample may not show any lines that are straight. If

this is the case, mechanical component replacement may be required. Please contact our Customer

Service Department for assistance.

High Speed Raster Enhancement

When laser engraving lightly (power settings below 30%) on materials at high speeds (speeds above

50%), and also depending on the graphic (text under 12pts in size or finely detailed images), it may be

beyond the physical nature of the material to be able to respond to extremely short and extremely fast

laser pulses. The laser pulses may be so short in time (a few microseconds) that the material doesn’t

reach vaporization point and will therefore show little or no signs of engraving in some areas of the

graphic.

For example, the thin lines or the serifs of an 8 point, Times New Roman font, may faintly appear or may

not appear at all if trying to raster engrave this font on micro-surfaced engraving plastic at 100% speed.

In the past, the only way to overcome this limitation was to slow the speed down and reduce power until

the entire image engraved consistently. This could result in having to use raster speeds as little as 50%

for the detail to appear. Now, with the development of this unique driver feature, we have the ability to

enhance the laser system’s performance when processing these types of materials at high raster speeds.

Enhancements ONLY work with black colored objects using the black driver color setting.

To use high speed raster enhancements, first determine if your power setting is less than 30% when

running at 100% speed for your particular material. Also, run a sample and observe the high detail areas

to see if some of the detail is lost. If both criteria are met, then enhancements may be needed.

Using enhancements is a three-step process. Please follow these steps in the order shown.

Step 1: The first objective is to establish the MINIMUM power level necessary to engrave the material

cleanly. To do this you will need to create a calibration scale and engrave different power settings to find

the right value. In your graphics software, create a black filled rectangle that is 6 inches wide and ¼ inch

tall. Duplicate this image 4 times, one right below the other spaced .05 inches apart. Start with a power

setting of 5% and increase power 5% for each successive rectangle, for example:

ABCDEFGH I JK LMNOPQRSTU

In the above example, “K” would be the best choice

1 2 ... 36 37 38 39 40 41 42 43
