Hello,
Lightburn user since 2020
AWC608C controller, Win7 Dell Desktop
Connectivity via ethernet through 8 port switch.
Setup has been working for years without issue.
All cut files deleted from controller memory.
Laser CAD operates perfectly from the same computer and hardware. (Computer, cable and network)
Lighburn V1.7.06 has lost ability to transfer files. The “Transfer failed” pop up is always displayed.
The laser will respond to “Home” and “Go to Origin” from the Lightburn Laser menu. So there is some communication.
“AWC608” shows in the “Devices” list. IP address is correct. Stopped working after upgrade to V1.7.08 No other changes. Reverted back to V1.7.06 still not working.
Tried installing trial version of V2.0.02 on a different WIN10 machine connected via same network and cable. Same “Transfer failed” error.
Been trying to get back functionality for three days.
I believe LB 2.0.xx is Win10 and later. This was stated in the release notes.
To restore 1.7.06 to operating status, install a previous .lbprefs file dated before the update day. This should work if it was working before.
You would have to do a complete install, including the CH340 driver and the C++ Runtime files update.
Because Win7 is not supported, try setting up LB 1.7.08 (latest before 2.0.00) on the Win10 machine. You will then have an upgrade path for 2.0.02 Lightburn. Use the .lbprefs file that worked.
Understood, that’s why I installed it on a second computer running WIN10.
The first system, with the problem, was running WIN7.
I did the C++ Runtime update. I don’t think the CH340 driver is needed for Ethernet? I didn’t know about the .lbprefs files. Thanks.
I will try your suggestions tomorrow evening.
I have a Ruida, it doesn’t have software for reset, home or go to origin.
Since you’ve changed everything, it seems like you should double check the network.
On a Ruida, the address is static, you have to allocate that address in your router to be applied to the MAC address of the laser. If you don’t do that, then it’s easy for a different boot sequence in your system to attempt to give it another address. This ends up as duplicate IP on your network.
This can create these issues.
Again, my Ruida may handle IP address differently, but you’ve swapped out everything else.
Hello Jack,
This is a WIN7 pc with V1.7.05
Yes, Lightburn shows “Ready” in the laser window.
I’m not sure what you mean by “Since you’ve changed everything”?
On the Trocen AWC608, the address is also static. Been the same for years.
You can see the “Home and Go to Origin” buttons in the screen shot. They work as expected.
I can ping the controller from this PC as well.
Hello Jack,
I have also tried a new install of V2.0.02 on another PC on my network. A WIN10 PC that has not had Lightburn before.
Also shows “Ready” Also “Home and Go to Origin” work. However it has the same “File Transfer” error? And I can ping the AWC608 from this PC as well.
Yes, my machine is in the garage, so I always run it from the console… Don’t remember seeing those as you have to use the console on mine to set the user origin.
In any event, it could be you have a hardware failure or the only other item could still be the network. If you have the machines IP excluded from the router, then it’s likely a hardware failure.
It may work for years, but some kind of change in how the IP addresses are allocated can cause issues. I just want to make sure it’s not this. My Ruida uses UDP/IP, so there is really no error control and it doesn’t care who sends it controls, crossing up the IP could cause a failure. Just be aware.
Other than that you might be looking at some type of hardware failure. I’d double check to see that you don’t have a bunch of file stored on the machine. I know the Ruida becomes a bit cranky if you use up it’s memory. I’d try to delete files, all of them is possible, then try it again.
Does it have a usb port?, try that, this is usually the last thing I’d suggest, but…
As a quick test, turn the laser off and try pinging it again. If anything replies, the router has assigned the laser’s IP address through DHCP to another device, in which case you must fix that.
There is no response to a ping test when the laser is powered off or disconnected from the lan.
The WIN7 computer with LaserCad and Lightburn installed, still works fine via LaserCad via ethernet. This has been my long term operating setup.
Since the laser responds to home and go to origin commands there is obviously some form of communication between the two. How full is the controller? What does the file list show in Lightburn? Sometimes the controller does annoying things when it’s memory is full or close to full.
Window Menu> File List. This should show all the files loaded on the controller. You can delete files from here. Worth a try.
I would agree that some communication is taking place. The controller is completely clear of Lightburn work files and LaserCad work files.
I can send files to it from LaserCad from the same PC.
Can you talk with it in the File List window? Just one more communication test.
Edit: Although if there are no files there at all the file list just shows blank. But if it’s not communicating, I believe the buttons are grayed out. Send a file from lasercad and see if Lightburn sees it.
Thank you for your input. I was hoping this would be the issue.
As I keep stating:
The system is working with LaserCad via the same ethernet connection. However I have been using Lightburn as my daily driver for a long time and wish to regain the functionality I had until a few days ago.0
If it works with your software, but not Lightburn, then it’s unlikely to be the network.
When you use Ethernet, it’s like a box, you put data in the box and tell the OS to ship it… After that it’s out of Lightburn hands. When it arrives, the device takes the data out of the box. Working with one and not the other would eliminate the network. I don’t know of any general software that handles I/O other than through the OS… it would sure limit the portability.
I have no idea how Lightburn determines what fails with a Ruida. UDP doesn’t have an kind of status return.
Maybe one of the Lightburn people can enlighten us, like @Rick – we’d take it from whomever knows.
Still no success. Getting to be a critical problem.
Why would a fresh install on another computer give the same “file transfer” error.
There must be some work around. It was working …
Now that staff has returned from travel, are there any ideas on what the issue might be?
Do I have to go back to LaserCad? That would be very bad indeed.
