3. Connect to engraving machine
Step 1: Make sure the COM port
01

Your Windows OS recognize your engraver as a serial COM port,once the engraver is connected, as per type of control board this port may appear in the computer’s device manager with the name “USB-SERIAL CH340” or “USB Serial Device” or something else.

The name it appears as in Device Manager strictly depends on the type of machine; if no name appears,or if a device with error symbols appears, driver may need to be installed.

Usually the most common control board uses CH340 chip; If your system cannot recognize the serial port, click ‘arduino CH340G’ to download and install. Alternatively, you can install CH340 from the Tools menu in LaserGRBL. Download link 2.CH341SER.EXE – Nanjing Qinheng Microelectronics (wch-ic.com) 3.https://asa.atomstack.com/downloadWindowsDrivers.do3 Install CH340 with LaserGRBL from the “Tools” menu:
02

Step 1: Connect to LaserGRBL LaserGRBL continually checks for available COM ports on the machine. The port list allows you to select the COM port to which the control board is connected.This port number corresponds to the port number displayed near the COM ports in Device Manager. Please select the correct baud rate according to your machine’s firmware configuration. The most common baud rate is 115200.

On the bottom-right of LaserGRBL interface you should read “Status: Idle”

When the correct Com port is recognized and connected, grbl reports “‘$’ for help showing Grbl firmware version.

If you see “Disconnected” or “Connecting”in status,no response from the engraver, you might need to change your COM port configuration.

03

Normally it is possible to exit the alarm state using the “$X (Unlock)” command or by carrying out the “$H (Homing)” procedure ­ for machines equipped with limit switches.

Multiple engraving/cutting passes setting LaserGRBL has a numeric switch to perform multiple passes.

4.load and send
If we have not a program under execution we have the ability to load a file from disk. Use file open button near “Filename” box, or from file menu.

5.Import pictures
Raster import allows you to load it GCode instructions without the need of photos, clip art, pencil drawings, logos, icons and try to do the best with any kind of image. It can be recalled image of type jpg, png or bmp

LaserGRBL support G-Code with .nc and .gcode extension. If your file has a different extension but they are G-Code, you can rename your file to use this extensions.LaserGRBL also support opening pictures and raster images in bmp, jpg, png and gif file format.
