I have had my Sculpfun S30 for over a year. It ran great until a few days ago. I got a message in the middle of a job that said the USB connection was lost. Ever since then, I am having a problem with it rehoming. At first it wouldn’t move at all now it moves but makes a strange grinding sound. I have tried the belts and wheels. I tried with a different USB cord and that didn’t resolve the issue. I am getting this message:
"Waiting for connection…

Any troubleshooting ideas would be greatly appreciated.
Sounds like the controller went into lala land.
Launch Lightburn with the laser off.
Open the Console window and select Show All.
Turn on the laser.
In the Console window, enter $$.
Now enter $#.
Now enter $I (letter i)
Now enter ?.
Copy everything in the Console window and paste it in your Reply. This may help us determine which direction to go.
This shows that the laser is not connected correctly. Try toggling the “enable DTR signal” option in device settings. If you can’t connect then, you should try to flash the firmware again. Firmware Update & Settings - Diode Laser Wiki
