Did you make any changes to the computer prior to the issue?Įrror code 28 indicates that the drivers for that device are not installed.Īs of now I suggest you to restore the drivers to previous version by rolling back. To restore a driver to its previous version, kindly follow the below given steps. Double-click the category containing your device driver, and then double-click the name of the device that you want to restore to a previous driver version.You must be logged on as an administrator to perform these steps. If you are logged on as a standard user, the button will be dimmed, which means it's unavailable. Usually when the machine is in Alarm status it is necessary to execute the homing procedure (if the machine is equipped with mechanical limit switches) or simply press the padlock button to acknowledge the alarm.You must be logged on as an administrator to roll back a driver. The machine is connected, and this state comes from the machine: it does not indicate a LaserGRBL problem. If you see “Status: Alarm” it means that your board is in an alarm state. Note that LaserGRBL only recognizes engraver that use the standard GRBL protocol, and cannot connect to other type of protocols. If you see “Disconnected” or “Connecting” but no message come from the engraver, maybe you should change something in your COM port configuration. On the bottom-right of the LaserGRBL interface you should read “Status: Idle” When connected to proper port grbl reply with “welcome message” showing Grbl firmware version. Most common speed is 115200, older controller sometime use 57600. Please select the proper baud rate for the connection according to your machine firmware configuration. This port number is the same shown near the COM port in device manager. The list of ports allows you to select the COM port which your control board is connected on. LaserGRBL constantly checks for COM ports available on the machine. Please note: although most of the engraver use the CH340 driver there are some models that do not use it: refer to the manufacturer’s instructions to find out which driver to install.

Is it also possible to install CH340 driver with LaserGRBL from “Tools” menu: Google for “ arduino CH340G” if your system does not recognize serial port. Usually the most common controller board use the CH340 chip.
Refer to the manufacturer’s instructions to find out which driver to install. If no name appears, or if a device with an error symbol appears, you probably need to install a driver. The name with which it appears in the device manager strictly depends on the type of machine. Depending on the type of controller board this port may appear in the computer’s device manager with the name “USB-SERIAL CH340” or “USB Serial Device” or something else.

Is it necessary that your Windows OS recognize your engraver as a serial COM port once connected. Step 1: ensure COM port is recognized by the OS
