Hello,
I’ve been using a sculpfun s30 5w and it’s been working perfectly however today when I tried to make it work it seems like it does not connect properly. If I’m using Lightburn and send data it appears the error of paused or busy. However in the console part there is info always appearing and changing.
I attach a photo of the console, the info is always adding which didn’t happened before.
Your nickname made me laugh. (At least, any Portuguese will understand) Those who don’t understand can always use google. 
So,… I know some brands of machines needs a kind of reset to memorie to end this kind of problems but I am not sure if it is your case.
For start point, I follow this procedures and come back with the results.
At least until someone more knowledgeable than me comes to help.
Ahaha definitely Glad you liked it 
I already followed these steps, changed the usb cable with another that I’m 100% sure it’s working. Tried in another pc and the same happened.
So from my research I’m almost 100% sure it is a firmware problem but I can’t find a clear step by step on how to reset it. I already found the files on sculpfun website but they are not clear on how to do it
Have you tried sculpfun support? They might be aware of this kind of problems too.

Hi again, so it was indeed the firmware. I flashed him and its running again! Thank you all for your help
