“there was a problem sending data to the laser. The machine may be busy or paused”
we are at the end of our rope with this error. We rely on this laser cutter, the controller and this software to get the job done. We need some help here. We have been dealing with this issue intermittently and now its constant.
File gets sent but error appears. Job starts but only a portion of the job prints. We have troubleshooted everything to the best of our knowledge. Hardwired through USB, or through WIFI we get the same issue. We are using the ruida644xs along with Win10 and running the most recent copy of lightburn.
We need to fix this problem ASAP. Any support would be appreciated.
No we didn’t. We didn’t purchase the machine to do it that way. It normally works either wirelessly from the laptop or via usb (neither work now). I did consider trying that but didn’t see it solving my issue.
So controller was connected to an Ethernet switch on the same network as your WiFi network?
And you’re saying you have the same exact symptoms going WiFi->Ethernet as you do through USB? If so, that’s very interesting. As these methods of transport are very different. If you’re experiencing the same type of symptoms on both means the issue is likely on the controller side or possibly something repeatable on the computer side.
Is there something displayed on the controller when you get this message?
Is there any pattern at all to when you get this message? You say that it used to be intermittent but is now constant. Do you mean to say you get this 100% of the time now? As in you cannot start a job at all now?
Are you using the Start button or Send button to initiate the job?
There may still be value in testing this to see if there’s an inherent problem with the laser function or if it’s indeed limited to the transfer of the message.
yes to controller connected to ethernet switch on same network.
yes to same symptoms. Exact same symptoms. It begins to send, a very small percentage moves over to the controller/laser. It then begins to cut but only a small percentage of the original file and the error appears.
I have tried another desktop and the original laptop and I get the same symptoms.
Nothing displayed on the controller
I get this 100% of the time now. we can only do very small jobs at a time.
Have you tried increasing the “Network timeout” in Device Settings? Might be worth a try.
Have you tested this with RDWorks? Any change in behavior?
Try a different high quality USB cable. How long is your current cable? Is it a straight connection from your computer to laser? Or is it going through a hub or something else?
Can you try connecting your computer by ethernet? There are known problems going through WiFI to Ruida controllers. Connecting through switch is probably fine. Connecting directly from computer to laser is most reliable.
Please try the suggestions @berainlb has offered and let us know the answers to the questions above, as they will help identify the root problem(s).
Additionally, have you tried to connect directly to the control module inside the laser cabinet? This would rule out bad cables from external chassis port to control board inside.
Another test that might be informative, you can roll back to the last, known to be working for you, version and see if you observe different results. Older Version link.
This has been an issue that has plagued users for a vouple of years now it seems. If you do a search you can see people trying to troubleshoot this same issue no matter what version they are using.
I have tried, but I may not have changed it to anything that would be of benefit. Im a bit cautious when it comes to changing parameters like that. Does anyone have a number they might suggest?
I cannot use RDWorks as it is not compatible with the files we use (.svg)
usb cable is of high quality. It is about 12ft going directly to laser usb input from the laptop
we have connected computer to ethernet with no difference in behaviour.
Is there a version of Lightburn that is known to be bulletproof when it comes to these issues. We cant be the only ones having problems. As i am not the one who uses this software on a fulltime basis, its hard for me to tell which version might be of benefit so to do a rollback. This is my wifes Laser cutter and shes the one using the software on a fulltime basis. Its hard for me to get this kind of info.
LightBurn will allow timeouts up to 20000 (20 seconds). Try increasing to 10000 to see if this changes anything. It’s possible that the controller is taking time on larger files to process and not responding in time.
Perhaps try saving the .rd file from LightBurn and run from RDWorks. This will help narrow down whether or not it’s a software issue.
12 ft is quite line for USB but given that you have the same issue with Ethernet there’s likely something else going on.
I know you said there were no files on the controller but perhaps try formatting the storage. There might be unseen crud hanging around.
