Once you have installed the USB Driver of this machine (for use with USB connection) and have connected the LV-
290 to your computer, you will need to familiarize yourself with the LV-290 control panel and Printer Driver. The
printer driver will be where specific laser parameters for your jobs are configured, while the control panel will allow
you to set repeat times, manipulate file order, perform auto / manual focusing, and more.
5.1 Using the Hardware
5.1.1 Laser Key Switch
Turn the key-switch to the “ON” position BEFORE powering on the machine. If the key-switch is turned to the “OFF”
position, the laser will be disabled meaning that the laser will not fire although the XY motion system will still move.
The laser firing will need 8-10 seconds to warm up if turning to off, and turn on later, therefore, please wait 10
seconds before pressing STRART button for laser work.
5.1.2 Adjusting the LCD Display Screen’s Contrast Setting
Depending on the lighting of your immediate work area, you may need to adjust the contrast of LCD display screen.
You may increase or decrease the display screen’s contrast via the contrast adjustment wheel found on the inside of
the front cover on the bottom, right-hand side. You can access this area by opening the top window and looking
inside to the rear, right side of the work area (as shown in the picture below).
