Hello, We are unable to connect our laser (Arcbro 2440mm x 1200mm) (Ruida RDV6445G) CO2 Laser to the PC. We have tried 2 differnt PC’s and also tried the ethernet cable and the usb cable, we also have tried to save a file from lightburn and plug it into the USB on the CO2 Laser it self.
When we sent the project to the laser we get the followinf busy error.
Also, it is still disconnected - have tried find my laser and also manually.
This has been working but since November 2024 we can’t get it to work.
Any ideas please?
First check the status on the controllers keypad LCD screen. This message often occurs when the controller is in an error state. Is your machine trying to home? Did you try and run a cut with your chiller/water pump off?
Have you installed the FTDI driver file during the installation of LightBurn? Ensure Install FTDI serial driver is checked…
You mentioned using the USB drive. What happens when you try that? What steps are you going through and what do you see on the LCD screen on your laser cutter?
Does your Ruida controller work at the controller, if you click “File” are there any old files on their you can use to test your controller is working?
Hey Dominic,
We have uninstalled lightburn and reinstalled with the FTDI Driver already.
Lightburn shows as disconnected.
Rudia controller - if we go to the file on the “u-disk” we had a file on there back in november and ran it and it worked, we have deleted that file now and can’t get it back. I have also tried sending a file to a USB thumb drive and then insertign that thumb drive into the laser itself but it shows as “no files”.
Just to add we have checked the IP address’s to for the computer and the Ruida controller - they are the same.
I’d follow @Dominic advise to check the display and ensure you have no errors. With an Ethernet connection, these have an icon to show when they are connected.
The most dependable way to talk to the Ruida is via Ethernet. The most easy way is to connect your Ruida to your local Ethernet network.
The Ruida must have it’s IP changed to match your local domain, generally speaking, all but the last octet. You probably have to tell your router to avoid issuing the Ruida IP – else it could give it to another device… You can’t have more than one device on a network with the same IP address.
Then create a new device and give it the Ruida IP address. It should connect over the lan to Lightburn.
If you’ve tried to connect directly to your pc, this can be done, but you have to understand how Ethernet works. Too late for me to go into it now… so sing out if you want some more details about doing this. I’ve found it not too functional, but that on me.
and when you are on it, check if the cables running from the controller to the usb and ethernet are connected, maybe try to re-attach them. Wouldnt be the first one with a cable that is not connected tightly.
Follow @jkwilborn’s suggestions for ethernet. Alternatively, to get you up and running and to be sure your machine is working properly (because if your controller is borked and this can happen I had one fail last week) why not try a basic windows laptop with USB or something as a way to diagnose if the controller is working.
My main point is to try something entirely different from your current setup to see if your controller is working okay.
