Sculpfun S9 not connected with lightburn software

When I am connecting Sculpen S9 to my laptop this screenshot is happening and nothing else is happening please tell me how can I connect it

Have you setup your laser?
Can you do screenshot of console and laser window open?

The laser is not found automatically. Just add it manually. That’s no issue and not difficult. All steps are described here:

Ok, then LB is set up correctly. Though you have a firmware issue, you need to reflash it. Refer to this guide to flash a new firmware version (yours is an S30 mainbaord, choose that version)


i am not able to understand any of the settigs, everything is messed up and nothing is being done properly. working on this software, working on this machine, it has 4-5 days is giving me headche, i dont know why i purchased it, If you have any video in which this problem can be solved then please tell me, i am worried.

It’s a very simple problem. The firmware needs to be flashed again. Go to the guide linked above. Download the S30 firmware and the MKS upload tool. Run it, select the correct COM port and then flash the controller. Then it will work again.





After download THERE IS VLC FILE AND Yaml file what i do next?

after download MKS this shown


what should i do next ?

The first download is correct. Just extract the .bin-file to some directory. The second is wrong, that’s another configuration file. You need a download tool. You can also use this one: https://sculpfun.com/pages/sculpfun-software-download go to that site and select “windows tools”. Install this one and start it. should look like this:



still it is not working

What was the name of the firmware file you flashed? Did you power cycle the laser?

Thank you my machine is working. pls provide the settings for 3mm pine mdf cutting.

This depends on many factors and there is no general answer. I recommend starting with 400 mm/min, 90% and then check how many passes you need. Here are some additional tips: Settings guide - Diode Laser Wiki
