In the following,  all initial settings that have to be done in order to mark a first grayscale bitmap are explained.

•Settings → System → Extras:

oEnable Improved Bitmap Handling mode.

oEnable Dynamic Grayscale Map and set the Interpolation to linear.

•Settings → System → Optic → Advanced:

oSet PixelAM

oDefine the Laserport as AM Port.

•Open the System Pixel Map and click Reset to default. (Mark Property Page → Advanced ...)

•Pen Settings:

oMain:

▪Frequency = 100 kHz

▪Power = 10 W

▪Mark Speed = 5000 mm/s

oScanner:

▪Jump Delay = 1000 us

▪Jump Speed = 5000 mm/s

oBitmap:

▪Choose mode: Gray Advanced

▪Acceleration Ramp: 2000 µs.

▪Set all other parameters to 0 µs.

▪Disable all other checkboxes.

•Laser Parameters:

oOptical pulse duration: 8 ns (was set in the Laser Software - not in SAMLight)

•Import the SCAPS Test Bitmap or another appropriate test bitmap (which shows black, white and intermediate grayscale values) and adjust the position and size.

•Apply a pen to the bitmap.

•Bitmap property page:

oEnable Scanner Bitmap

oSet GrayScale

oDither Step = 0.05 mm (1:1 ratio of the pixel distances in X and Y when Dither Step = Mark Speed / Frequency)

•Bitmap Extended:

oDisable all checkboxes. The first markings are done unidirectionally (bidirectional disabled).
