Knowing what you’ve tried will help us avoid recommending those same solutions.

Like these:

> **[ALARM:3 - GRBL Errors - LightBurn 2.2 User Guide](https://docs.lightburnsoftware.com/2.2/Troubleshooting/GRBLErrors/#alarm3)**
>
> GRBL devices have a number of different alarms and error codes you may encounter. These will be visible in the Console Window. | Explanations of common GRBL errors.

My guess is a USB problem, per _many_ previous discussions:

> WOO HOO !!! I got everything working right , FINELY !!! What was the problem? It turns out to be the USB to Controller board cable was faulty. That was the only thing I failed to check and that was it. I have a bad habit of buying one to use and one to loose. When I thought about the cable being bad, I got the cable out the spare controller kit and that one worked. I feel really stupid sitting here thinking how I spent 4 to 6 weeks crying and trying to fix this thing and never though…

> I have just purchased a Gweike Cloud RF laser, using with Lightburn. The supplied USB cable works fine but it’s very short. So I bought a nice long one, 5 metres length. USB C to USB A, I use Macs. It’s a good quality cable, but I don’t seem to be able to make a connection when I plug in to the laser and to my Mac? Any suggestions/fixes most welcomed. I came across a really useful post by @BillieRuben who seems to have knowledge of these machines and setting up, any idea Billie ? tia blush

My notes also indicate a defective power supply can also cause an Alarm 3 message.

What I don`t understand is had cut several pieces before the Alarm:3 code came up. I just assumed it was a graphic problem (Too big, outside the boundaries, etc)

That is a different alarm.

Can you list the history of what the machine had done (run time, power output, etc) for the first 3 projects?
