I have been using a Sculpfun S30 5W with GRBL GCode, for about a year using Windows 11 with no problems until now.
I am running the latest Lightburn 1.6.03.
When I have set my work up and ready to cut or engrave, I select home than Frame with laser on 0.25% power no problem , but as soon as I select Start I get Connection Lost and Laser cuts out.
I have checked the USB cable and all electrical connections.
I have run out of ideas, any help would be much appreciated.

You are demanding a lot more power. Maybe the power supply is bad. If the air pomp is fed from the motherboard, that might be the problem.

Hi Mike, thanks for your suggestion.
I have tried a small piece of work on first power up with no problems, then tried another piece, by this time the power supply had got warmed up and lost connection as soon as I hit it start. So looks like it is the power supply.
Now need to find how to get a replacement.
Thanks again.
Terry.

If either of my supplies go out, I will replace it with one of those 30 amp switching units in a perforated box. Cheaper too.
