Laser Fire won't work and laser wont come on

I’m very new to lasering - I have a sainsmart 3018 PROver with the blue 5.5w laser module kit. I cannot get the laser to work so am guessing I haven’t set this up correctly. When I press the fire/PWM button in the laser stays on permanently so I know it works. I just cant get it work with the fire button using Lightburn - I’ve followed tutorials but cannot figure out why it wont work. I’ve spent about 2 days trying to sort it out and am on the verge of giving up! Can anyone help please? Thanks in advance

What is your power set to under Edit > Device settings?
On LightBurn Cknsole window type $i then press enter key, type $$ then press enter key.
Copy / paste here all the output.

Also does the bottom 3 pin socket need to be connected - I cant see where this would go. I’m using mains power

I’ve tried the above settings - no joy unfortunately
Can anyone help?

As a good practice always insert and remove your machine plugs with power and USB disconnected.

  • Post a screenshot of Edit > Device setting.

  • Can you post a better picture of the selected zones were we can read the letters?

  • Post a picture of the connections at the other end ( laser module).

  • Check if your 3018 controller has a switch for laser.

  • If your 3018 has a hand controller unplug it and try again with Lightburn.

  • At last try with LaserGRBL program and report back.

Hi
Thanks so much for all the help - I think I’ve fixed it. Just need to understand how to home the laser to an origin point and where to out my piece of leather in two to the image

Read this Lightburn doc:

Do your tests first in cheap cardboard.

Thank you!

Forgot this one:

Happy lasering.

Fingers crossed
Thank you for your help!

Does anyone know the typical $100, 101 & 102 values should be for a 3018 PROver
The image I’ve designed is so much smaller that the laser engraving and I wonder if these setting are wrong
Thanks

You can calibrate your axes.

I see some 3018 with lead screws and different values, but if you´re getting bigger output maybe 800 or 1600.
The number may not be a round number just a ref when you calculate the values with the above “tool”.
