  1. Make sure the computer can see the controller. Run in a terminal:
lsusb
  1. Validate that a terminal device was created for the controller. Run in terminal:
ls /dev/*USB*
  1. Confirm that you setup user/group permissions for serial communication. Did you run these lines from the Installation instructions?
sudo adduser $USER dialout && sudo adduser $USER tty

If you can answer in the positive for all 3 then you should have everything you need to connect. Right click-on “Devices” button in Laser window to force reconnect or pull-down the Ports field and manually select the relevant serial device.

Thank you for responding.
Item 1 ok
Item 2 s /dev/*USB*

```
trevor@trevor-System-Product-Name:~$ ls /dev/USB


<i><b>```
ls: cannot access '/dev/*USB*': No such file or directory
```</b></i></b></i></i>

What was the output?

This means you have no terminal device created.

Can you run this in a terminal?

dmesg | grep -i smoothie

Can you confirm if you competed the 3rd condition?

Terminal not my preferred option.
Am a bit confused. here is summery from the terminal that i just ran…

Lightburn shows:-

Can you run this in a terminal?

ls /dev/smoothie*

Also, can you take a full screenshot of LightBurn?

Also, did you change this command? $USER should have evaluated to trevor. You wouldn’t want $trevor.

User re run
trevor@trevor-System-Product-Name:~$ sudo adduser trevor dialout && sudo adduser trevor tty
[sudo] password for trevor:
The user trevor' is already a member of dialout’.
The user trevor' is already a member of tty’.

trevor@trevor-System-Product-Name:~$ ls /dev/smoothie*
ls: cannot access ‘/dev/smoothie*’: No such file or directory

Delete all but one of those devices.

Then can you push the pulldown button between “Devices” and the device profile “Smoothiware” in Laser window? Take a screenshot.

I’m concerned that your serial device cannot be detected but I’m not super familiar with how that might be setup with your particular board.

Can you try running this in a terminal session?

ls /dev/*smooth*

If that returns nothing just run this and return all results:

ls /dev

Success berainlb, i can go to Home and Origin, just have to get used to switching from Whisperer to Lightburn, thank you for your patience and help…Trevor

That’s great. What ended resolving the issue?

To tell the truth don’t exactly know, just went out to workshop with the intent of doing battle with the setup again, loaded Lightburn and to my surprise i heard the X and Y axis fire up and moved to Home.
For your interest a couple of pics, had a hard landing rebuilding part of fus…

I think it was putting $trevor instead of trevor.
Thanks for your help berainlb in resolving this issue. Trevor
