Monport and Lightburn no longer connect through ethernet

[TammyLC (Tammy Chizma)]

Lightburn no longer will connect to my machine ( Monport co2 80w) I have tried resetting both machine & software. I checked, ethernet ips are the same. I don’t know what to do, I need desperate help & now I have orders to do with the rotary & it’s not working.

ethernet ips are the same

It’s possible another device has popped up on the network, the router has assigned the laser’s IP address to it, and those two devices are responding to the same packets.

Changing both the laser’s IP address and the LightBurn setting may help, at least temporarily. The doc describes the process:

Connect to a Ruida Laser via Ethernet - LightBurn Documentation

A long discussion of how to go about checking for the router handing out the laser’s address may be helpful:

Hello fellow laser wizards

I just changed them both again to a different last number again & still not reading my machine.

still not reading my machine

Time to get more information so the hive mind can ponder the situation:

• Photo of the machine display showing the laser’s IP address
• Screenshot of the LightBurn Device Settings showing the laser’s IP address
• Screenshot of the Windows ipconfig results
• Does the machine controller’s display show the network is connected?
• Screenshot of the Windows ping of the laser’s IP address from the PC
• With the laser turned off, screenshot of the Windows ping when you ping the laser’s IP address

Type those commands in a Command Prompt window that you start by hitting the Win key and the R key, then typing cmd into the run dialog box.
