You will need to provide more information for anyone to give you effective help.

Which controller board do you have?
What software are you using?
What firmware has been installed?

A link to the machine you bought would help.

Are you sure you have positioned the jumper under the CPU to 0.9 ?.?
By default it is set to 0.8, which uses a different laser management pin.

Benbox uses its own firmware and operates the laser ON-OFF mode on pins D12.
Grbl ver 0.9 and above use the pin D11, in PWM mode.

Just wondering if the home  insurance is up to date?
.
Lasers are wonderful machines..not ONLY  can they cut a finger off BUT  they can also cauterise it at the same time.....

If you are using benbox, you need to use their custom firmware. It is a customized version of grbl 0.8
Laser: A5 2000mw with L7 Board / A3 2500mw PWM with Mana SE -- All using T2Laser
3D Printer: Monoprice Maker Select v2.1

Where can I find instructions to move the pins?
When I download a firmware there nothing, neither a Readme.txt

Instruction valid for Eleks board L7:

Carefully remove the Arduino Nano board.
The Arduino Nano board is the one with the USB connector
Under the board you found the jumper marked 0.8 and 0.9
move the jumper to 0.9
refit the Arduino Nano board the SAME position where it was before removing it.

If the card is not Eleks L7, there may be different procedures.

One more little note.
When you are experimenting with potentially dangerous objects (like a 5W laser)
It MUST take ALL the necessary precautions, keeping a finger on the emergency button.
It's normal that in early testing of new hardware something can go wrong.
But if the laser damaged the floor is because he had no protection and therefore would will still damage it.
Fortunately, you were not looking the laser beam.

focamonca....

Think you need to read this before going further with a laser OR  even switching the thing on..

https://en.wikipedia.org/wiki/Laser_safety

Also read on this forum how to make an enclosure for the laser.  Use of safety goggles etc.,(NOT just for yourself but for other people who MAY view the laser in operation......)

This forum has a search field at the top. Type in PWM Mod and see what you get...you might be surprised...

Just a little advice that I had forgotten in my previous post:
The lasers sold with BenBox machines have a small button
on the current regulator circuit (the one mounted in the top of the laser)
When pressed the laser goes into test mode and the power is reduced
as much as not to burn anything (but can still damage your eyes CAREFUL!)
Recommend to do all the tests in low power mode
and activate the full power only after you are sure that everything is OK.
