Lightburn Bridge Not by Lightburn

LightBurn Hardware Compatibility LightBurn Bridge

I have a brand new Raspberry Pi 4b and I am trying to get LB Bridge to work. I have done the following:

  1. Burned the lasted Lightburn Bridge to the SD Card
  2. Booted the Raspberry PI and configured the network.
  3. Confirmed my Laser IP is 10.0.3.3
  4. I can see the Lightburn Bridge status page in my browser - it indicates there are no errors
  5. I can see the Lightburn Bridge status at the PI when I ssh in:
    LightBurn Bridge v1.0.0-RC3

Current Time: 18:42:10
Network: Connected → 192.168.1.246

Control Relay: Ruida relay started, laser IP: 10.0.3.3

Relay Info: ruida 1.0

Raspberry Pi No issues found

  1. I can ping the laser from the pi
    pi@lightburnbridge:~ $ ping 10.0.3.3

  1. I can ping my lightburn host machine from the pi
    pi@lightburnbridge:~ $ ping 192.168.1.139

  1. I have plugged my host machine directly into the the network port on the Laser and I am able to create a device at 10.0.3.3 and run the laser from my host machine.

  2. I have tried to manually create the lightburn bridge device, but it doesn’t ever show connected.

I have no idea where to go from here - My computer can talk to the LB Bridge; the LB Bridge can talk to the laser; the laser controller works on the LAN…

Help??

I just figured out how to use my manually created lightburn bridge device - and I am seeing this in the Relay log:

You’ve included a lot of good detail here but I’m missing the problem statement. I assume that things aren’t working as you expect but can you explain what exactly it is that you’re seeing?

Also, have you configured the Bridge device in LightBurn?

Resolved - my wifi was too weak.

Thanks,
Kevin
