At first, I am sorry. I don’t know English so I use google translator.
I have a licensed LightBurn. The device is a Sculpfun S9 laser plotter. The plotter has installed zero points in the lower left corner and updated firmware from the manufacturer. After connecting the laser and turning on the LightBurn, the device automatically sets to zero. The layout origin and the job origin are the lower left corner. Work is to start with absolute coordinates. Unfortunately, every figure you draw won’t start to cut. Instead, there is a warning that the target of the G-code motion exceeds the machine’s range of motion.
<Idle|MPos:-407.000,-397.000,0.000|FS:0,0|WCO:0.000,0.000,0.000>
ok
<Idle|MPos:-407.000,-397.000,0.000|FS:0,0|Ov:100,100,100>
ok
Starting streaming
ALARM: 2
The target of the G-code movement exceeds the range of movement of the machine. The position of the machine is held securely. The alarm can be unlocked (Right click on the “Devices” button to reset the connection).
On or near line 2:
Streaming will end in 0:00
[MSG:Reset to continue]
ok
Grbl 1.1h [’$’ for help]
[MSG:’$H’|’$X’ to unlock]
[MSG:Caution: Unlocked]
ok
If I use the go to starting point button, the laser head goes to the upper right corner. I am attaching a GRBL code dump in the machine:

and a screenshot of when I try to make a cut.
Additionally, I attach a screenshot when I run the option: get position.
The values for the X and Y axes with zero values become X: -407 and Y: -397.
Before turning on the laser, make sure the laser head is positioned on the front-left of the machine. When you turn on the laser the front left will be 0,0. This will allow you to address the entire work area.
According to the instructions, the zero point is in the front left. There I also have a limit switch mounted on the X and Y axes. Connecting the laser in LightBurn after the HOME command, the head moves to the lower left corner.
If you have access to a Windows computer this is even easier done using LaserGRBL as it has a built-in firmware update facility with custom firmware files included.
