So I recently upgraded from the Sculpfun S30 pro 10 watt to the 20 watt Pro Max. I since have not been able to get the laser fire button to turn on the laser when clicked on or during framing a project. I pulled the $$ settings from the console and the $30 setting matched up with the device settings S value at 1000. I cannot get it to fire the laser during framing or when the fire button is clicked on. Other than that everything engraves and cuts perfectly.

If the laser fires during normal operation you’re likely just not setting the power level high enough. How high power have you tried for the fire button?
I have turned it up to .50% with nothing visible. That setting was too high of a setting on my on my sculpfun pro 10 watt that I previously owned so I figured something
was outa sorts that I’m missing being I have a stronger laser now. I will crank it up tomorrow and report back if makes a difference or resolves the issue. Thanks for the suggestion.
You need at least 1% or even a little more. Before it does not fire, IIRC.
Same situation , My S30ProMax dose not work fire button . I tried many kinds way from this forum information . But never work fire button .

What settings did you set? It works fine. You might need to set at least 1.5% for the fire button to start working.
I have the same situation here, I have a Sculptun s30 Pro Max with the 1.2 motherboard version installed.
Does it work correctly apart from the fire button? Which percentages did you test?
Hi, yes, it does.
I’m running it at 1% but I did test until 5% with no luck. I changed the lens and clean up the nozzle and the inner lens too.
I already contacted Sculpfun to see if I did something wrong connecting plugs into the motherboard as you can see it in the photo.
That looks fine. If the laser is working at normal operation, there is no connection issue. The fire function uses the same electronics as the other operations. Just at lower percentage. You can go up to 20% for the fire button. Does 20% work?
Let me screw everything again and coming back with the response.
No, it isn’t working at 20% either. I ran some tests and it could engrave and cut without any issue but the fire button is not firing.
I’m using Lightburn 1.4.03 running on Mac OS Sonoma 1.41 if it helps.

Can you upload these screenshots please:
- Edit->Device Settings
- Move window
And did you choose “grbl” as laser type?
Everything seems to be correct in your setup.
One oddity is that you’re showing “cu.HUAWEIFreeBuds5i” as the serial port for the laser. This isn’t how you normally connect is it?
Can you go through these steps please?
- Connect to your laser
- In Console window, enable “Show all”
- Push “Fire” button in Move window
- Copy the generated output in Console and paste that as a reply here
I haven’t connected my Macbook when I did the screenshot, that’s why.
Let me do what you’re suggesting.
Waiting for connection...
ok

Did you use 20% in that case? Because the output shows that it tries to fire at 1%, which might still be too low.
This is likely the reason you can’t see the light although I’m surprised 1% isn’t actually bright enough to see.
If this was done while you are at 20% power then this may be from possibly an old bug I’m vaguely remembering.
If so, try recreating your device manually ensuring that GRBL is chosen. Make sure all other configurations are correct.
If I recall correctly, I only experienced this with the Sculpfun Pro Max (20W) module. I think this might be the driving electronics, 1% is just too low to let the diodes fire at all. With all other Sculpfun modules, I did not experience this, and they usually also fire below 1%.
