Installed Lightburn, it wouldn’t auto find my laser, added it manually using grbl controller.(tried others
and they wouldn’t do anything)
Adjust com port (varies with startup(no auto selection)), load image, save gcode, run gcode or just hit start, head moves then appears to work but laser doesn’t fire. In move window fire button works. In move when I hit the direction buttons the head move in a square. Then I have to hit the reset button on the controller board.`
I read most of the threads mentioning no fire. No luck. I did find the fire button with one though.
Ok… I tried another software it works, but only for about 1/4 of the image then stops. That’s all the trial allows.
$I enter said ok That’s all@
Just to make sure it wasn’t a 1 or lower case i , same result

T2laser trial< I don’t want to pay for anything till Know It’s what I need (Home projects lol)
The web page Says it uses Benbox, I’ jst having a hard time Figuring out which is the Right button with All the Advertising Around
I was hoping to see GRBL version information with the $I so that we could determine how to configure your laser. It’s concerning that it’s not reporting anything.
Can you try this. Click “Show all” in Console. Then power cycle the laser. If LightBurn doesn’t reconnect then right click on Devices. Make sure the correct port is selected.
It should have shown you some bootup information for the laser.
I’m finally certain that your machine is an Eleksmaker A3 Pro or clone.
It’s likely running an old version of GRBL. In which case you’d have to configure the device type in LightBurn to GRBL-M3.
Even better, you can update the firmware on the Nano to a newer version of GRBL and use the better “GRBL” device type. However, you may lose the ability to use Benbox if that’s a concern. I believe you can always change back if you want.
If you can provide the requested information in the previous post hopefully we can sort it out.
In the boot it says benbox, I ASSume that means it is benbox… Yet I don’t know lasers this is the 1st time for me lol
So I tried GRBL-M3 like you suggested…This time I restarted Lightburn Well it works sort of
now the laser won’t shut down, I hit the fire button twice or the reset.
Also it show 1 of 49 passes and when I run gcode it goes but after 6 mins it’s just burning a hole
in the wood, I believe it does 1 pass then repeats it … right ??? But it doesn’t look like that
I hope this is easier then the 1st problem
This is before I changed to GRBL- M3
Hit the laser button it fired
Tried the $I again same response
$$ and then ? with the ? it just continued till I hit stop

This is the console when hitting start
Head moves as if working but no laser
Not sure if it might help
Essentially, open laserGRBL. Go to Tools->Flash GRBL Firmware.
Pick Arduino Nano as Target. And suggest you first try v1.1h custom firmware.
Keep in mind that this will require some post flashing setup. Minimally for work area if you want soft limits to work. Possibly also for homing direction.
Some things you’ll want to note before making this change:
Does your laser go through a homing process when you power-on?
If so, to where does it home?
What are the coordinates when you are homed? Check this using Get Position in Move window.
What are the overall dimensions of your frame? This might be in your documentation.
Not surprised that comes up blank. It uses the same mechanism as $$ to get the information and that didn’t work either.
laserGRBL is a different program entirely from LightBurn. It is also quite popular for laser burning and is free and open source. You can find it in the link I included.
Okay. That could make this simpler although you still want to get the configuration correct.
