Hello,
I am using the laser cutting software Lightburn and I am encountering a problem:
My laser cutting machine (Chinese, CO2, 130W) is connected via Ethernet to my PC running Windows 11 Pro.
When I send a job to the laser cutter, I get an error message: “File Transfer failed” followed by “machine may be busy or paused.”
The IP addresses (all static) have been checked on both the PC and the Laser side.
There is no proxy or VLAN.
I am an administrator on the PC.
On another PC, it works fine under the same conditions.
I performed a ping and got a positive response.
I disabled the firewall as well as the antivirus, but this did not change anything.
I uninstalled and reinstalled Lightburn without effect.
I reset all the network adapters, without effect.
I launched Lightburn as an administrator with no change.
When a transfer fails, turn the machine off, then ping its IP address.
If anything responds, then the router has probably assigned that address to another device through DHCP. When LightBurn attempts to send the file to the laser, the other device collides with the laser’s responses.
In that case, you must (somehow) tell the router to not do that, with the details depending which router you have.
A previous discussion covers some of the intricacies:
As I indicated in previous question, “The IP addresses (all static) have been checked on both the PC and the Laser side.”
And there is no router between my PC and the machine.
There is just a simple ethernet HUB.
I still did the test you indicated and the ping does not respond anymore if the laser is off.
Sounds like you have it configured properly. Not clear what you mean by a hub, is this a switch? So it’s not on your lan?
I have this issue now and then, most of the time, I can just re-send it. Worst case is I’ve had to trek out to the garage and press reset on the Ruida console… I’ve never had a need to power cycle it, just a reset seems to work.
You can see the hardware lan indicator in the bottom right of your machines console. This is on my 6442g. Yours might have a pair of terminals for an icon down there in the same area. This only identifies it as hardware connected.
Hello,
The HUB I’m talking about is a simple Ethernet Switch.
I don’t think it comes from the machine. Indeed, it works very well from another PC in the same conditions.
I don’t have any indication on the controller screen but the network light flashes.
I really think it comes from my PC. The transfer is carried out in UDP and I think there is a problem at this level.
If it worked from another PC it’s on the lan. Does it still fail from the other pc?
If lan on the controller is flashing, then it sounds like it thinks it’s working… I don’t remember if it flashes when there is no software data or not…
Lightburn can only tell the OS the destination IP, if it’s a communications error, then it’s more likely to be at the controller end.
I’d look elsewhere as the controller is the expensive part and leave it for the last hope, so to speak.
