Good afternoon, I have a problem with my 5W laser, it is mounted on a 3D printer, the Ender 3 S1, everything works fine, but when I cut or engrave something in the movement between pieces the laser does not turn off and leaves a line engraved on the material, I have seen that the $32 option must be enabled, the problem is that even though everything works fine, when I enter the console and enter $$ and it shows an unknown command and if I access the machine settings everything appears blank, I have it configured in GRBL, I leave the code that the console leaves me when engraving the first image.
Thanks in advance.
What does console show when it first connects?

Does the device come with or support a laser?
It appears to be it’s using a cnc mode that doesn’t turn the spindle off between moves… this is common, and is corrected by the $32 variable to enable laser mode in the controller.
When you attempt to read the machine settings, it advises you there was nothing returned, so it’s probably a different variation of firmware.
Agree with @Dskall you need to show the first connection in the console which will tell us what firmware you are running.

Maybe try Marlin device?

Good morning, what appears when you connect is this, it may also be $$ and it says unknown command.
Waiting for connection…

Good morning.
It is actually a 3D printer, the Creality Ender 3 S1, but it is compatible with the 1.6W, 5W and 10W Creality lasers.
The problem is that I cannot access the console to change the variable $32 because the console does not respond and it does not give me the Firmware version either 
Thanks!

Ender 3S1 controller is based on a STM32 chip the last resort I can remember is creating a new Device based on Gerbil-STM or maybe GRBL-LPC and test.
And also check if they appears in Windows Device Manager or need a driver.

With Gerbil-STM it doesn’t connect.
With GRBL-LPC it doesn’t draw figures, it just makes a straight line and goes back home.
Thank you for your help 
Com5 is the port assigned in Windows Device Manager?

If correct, Windows assigns port Com5
Good morning, can anyone help me? Does anyone know how to solve this problem?
Thanks!
I suggest you send a note to support, if it’s supported they can help you determine which control board it has and which device you need to use in the device setup.
If you don’t mind hanging around, maybe @gilaraujo can help you figure it out.
A few questions regarding Ender 3 S1 (not Pro):
- Did you have the Creality laser control board or the laser is directly connected to the printer?
. - Did you update or is in the printer the firmware “Marlin2.0.8_Ender-3S1_HWv24S1_301_SWV3.1.9_Two_C_F401_FDM_LASER” or newer?

. - Did you test first with “Creality_Print-v3.12.2.3188-win64-Release”

Maybe you´ll want to try a Custom GCode with a Snapmaker (Marlin) based profile?
Edit: with your LightBurn 3 circles job click Save GCode and post here the the file.
