OneLaser XRF WiFi Connection using Lightburn Bridge

I am trying to set up lightburn to connect to this laser wirelessly. I can connect to it just fine using hardwire ethernet cable to my lightburn laptop but so far having issues trying to go wireless. I set up a rasberry pi i had laying around to be a lightburn bridge, I followed the guide plugged it into my laser, set my laser ip as 10.0.3.3 went through the lightburn bridge wizard, it found the rasberry pi but no laser. I have tried a few different things like changing the ip address of the laser and the .json file to a different subnet, something closer to my home network of 192.168.0.xxx i chose for the bridge 192.168.1.3 and set my laser ip to the same but that didnā€™t work either still no laser found though the bridge can be found just fine. If I then unplug the rasberry pi and take that same ethernet cable and plug it into my laptop and connect with lightburn ruida ethernet/udp device it connects just fine.

Any suggestions?

Read the entire thread, but the linked post may hold your answer.

Thanks for your response. I saw that post before posting mine and it was useful getting the hardwire ethernet working. However my issues comes after that. Once he was able to connect via hardwire ethernet he stopped there. I am trying to get lightburn to connect to the laser through the lightburn bridge wirelessly. I can connect to the laser with lightburn just fine hardwire ethernet.

@bretto311 Iā€™m the author of the other forum thread. Iā€™ll head downstairs and try to connect via the Bridge shortly and reply back here. I expect it to work, though. For some reason, Ethernet networking wasnā€™t working until I made those internal changes to the Wifi/Ethernet switch inside the OneLaser machine. Once I made the change, the Ethernet system ā€œwoke upā€ and was able to connect.

As an aside, I did try to use the internal Wifi system that shipped with the laser (Vonets?) and could never get it to work, either.

Confirmed. LightBurn Bridge connected first try with the new Ethernet configuration inside the OneLaser XRF.

Laser Ethernet ā†’ LightBurn Bridge Ethernet
Laser IP set to 10.0.3.3

No software hangs in LightBurn. Hope this helps!

Ok so when you say new configuration inside XRF you mean Ethernet button switch to Ethernet instead of Wi-Fi, ip address in XRF set to 10.0.3.3, hardwired to default lightburn bridge configuration on a raspberry pi, wirelessly connected to your home network and then you connect to the lightburn bridge inside lightburn wirelessly or through the home network?

Thanks for testing, I must have something wrong.

If your PC is connected to the same home wifi network that you connected the bridge to - then the Bridge Discovery Wizard should find it.

Yes my pc is connected to the same network and the lightburn bridge wizard finds the bridge just fine but the wizard shows no laser connected to the bridge even though it is. But if I connect Ethernet directly to the lazer with no bridge in between then lightburn connects just fine.

Correct

Correct. OneLaser Ethernet hardwired to Ethernet port on the Bridge.

Correct. Bridge wirelessly connects to my home network.

The Bridge allows you to physically separate your computer and the laser. They can be in different rooms. LightBurn running on the Mac in my upstairs office can now connect to and control the laser in my basement.

To do this on my upstairs computer:

  1. I open LightBurn upstairs, and click Devices
  2. Select the LightBurn Bridge option
  3. Run through the Wizard

Now instead of having ā€œNo Laser Connectedā€ (in your image above), you should see the OneLaser listed.

At least this is what worked for me.

What does the bridge relay log show?

Thanks for the replies, that is how I have it set up now but the bridge canā€™t find the laser. I am going to look at the bridge logs and maybe start over from the beginning and try again mostly because I kept changing things along the way. One question for clarification, your home network is a completely different subnet then the 10.0.3.xxx of the one laser correct?

Yes, my home network is of the 192.168.X.X variety

Make sure the bridge.json file has the 10.0.3.3 address in it.

I started from the beginning again and sadly still no luck. I lightburn can see the bridge just fine, but it still says no laser.

I double checked that the ipaddress on the bridge was 10.0.3.3, i redid the lightburn bridge pi os anyway but just to double check.

I made sure the onelaser xrf was 10.0.3.3 again

And just for completeness i took a picture of the hardware connection.

Iā€™m giving up for tonight but will try again tomorrow after work. Thanks for the assistance and replies if you can think of anything else, it would be greatly appreciated.

Nicholas- Here is the bridge relay log when i put that address into my browser. I didnā€™t have lightburn open when i typed it if that matters. Before I redid the lightburn bridge i connected directly to the laser via ethernet and was able to see it on 10.0.3.3 with my ethernet port set to 10.0.3.xxx something.

Thanks again for the help.

Hmm, your settings seem ok.

And it is strange since you can get a direct ethernet connection, so the static IP/ethernet port at the laser must be ok.

Everything seems to be pointing at the Pi and/or the connection from the pi to the laser.

Pi configuration issue?

-To be thorough - reflash the bridge image to the PI and try going though the bridge setup guide again.

Weak/bad connection from the laser to the pi?

-Check the cable is plugged in properly between the pi and the laser - disconnect and reconnect.

-Did you physically unplug the Wifi cable from the ethernet switcher port? Might help since @chill903 said it made a difference, maybe the switch is adding resistance or noise to the connection?

-For that matter you could try plugging the pi directly into the ethernet port of the Ruida motion controller - bypassing both the the external ethernet jack at the chassis and the internal Ethernet/Wifi toggle switch

Early on in my troubleshooting I tried connecting directly to the board and skipped the Ethernet switch. Still the same problem, Iā€™ll try that again tomorrow since I redid everything. Iā€™m using a raspberry pi 4 model B. And the is file I downloaded was
LightBurnBridge-v1.0-RC4.img.xz

I used the latest pi imager to flash the sd card. Iā€™ll try more tomorrow and use a different cable just in case. I just wanted to give more info.

Sounds like you have been pretty thorough, good to try everythingā€¦ could be as simple as a bad cable between the pi and the laser? maybe try the same ethernet cable you used to join the PC and the laser directly?

Might also help to power off the laser, and the PI. Wait 10seconds then power on the laser, and once the laser has fully started and finished homing, power on the Pi, and once that has fully booted and connected to the network you may need to use the ā€˜Re-scanā€™ button in the LightBurn Laser Window to re-establish the connection from LightBurn to the bridge.

Then try again, and check http://lightburnbridge.local to see the status of the bridge.

I ran mine quite a while on a PI 4b machine.

I used to fix comm gear, so my first look is to see if the ledā€™s indicate itā€™s connected and/or what itā€™s doing.


I see the lights on the PI, but no on the laser where the Ethernet is plugged in. Is it lacking status leds or is there a problem?

I expect to see these types of indications.

Some leds illuminate and will tell you if the hardware is seeing each other, but it may not be talking.

:smiley_cat:

Ok Iā€™m back at troubleshooting again, this time i connected the cat6 cable directly to the ruida controller.


I also redid the lightburn bridge pi OS just for good measure, used a different raspberry pi 4, i had on hand and went through the connection steps again and still no luck. I can see the bridge but no laser connected.

The lights on the Pi Bridge are right hand side (from looking at the port) amber solid, left hand side green. One thing i notice is when i first power on the bridge the right side goes amber, few seconds later the left side flickers green for a couple seconds and then goes solid green as in the pictures.

And here are the bridge logs.

Iā€™m not sure what to try at this point, I mean i can still use my laser with the hardwired ethernet (no bridge) and it works just fine but I really donā€™t want to have to take my laptop out to the garage every time i want to use this laser. If you guys have any other suggestions I would be happy to try, Thanks again for all the posts. I submitted a ticket with OneLaser yesterday but havenā€™t heard back, im a little bit dissapointed as a laser this expensive in this day and age should just come with wifi connectivity working.
