I’m running. Omtec 1624 With a. KT332N Ruida controller and LightBurn. 2.2.0 1.. The issue I’m having is. That when I click the home button in light burn. The Omtech does not respond. I can. Use the move buttons to move the. Laser head around the. Machine. The origin button works. But if I hit the home button it does not work.. Also when I open the controller The controller panel. It does not respond.. I cannot type in it and it does not show. Any commands Going from Light burn to The controller. I’m guessing that because I can move the laser head around With the move tabs and. The origin button. My USB cable is OK. I guess I’m just missing something Simple with LightBurn. On my last project, The controller. Would say there was a communication error, but it was still running the project As expected. Can anybody help me with it?

If you haven’t changed any of the basic settings in relation to how the machine was running while it was running… , I would strongly recommend using a LAN connection to your laser machine. I have been in a similar situation with the exact same machine/controller and speak from experience.

As you can see in the picture (from top to bottom, it shows my first to most recent attempts), some letters are randomly missing or partially cut when engraving text. I’m cutting at speed 50mm/s and power 35%. I’ve already tried applying an offset, and then used the Pathfinder tool (unite/merge) afterward — but there’s always a small issue somewhere. What’s odd is that if I cut each letter in… [image] Laser stops running after a few seconds Ruida controllers Hello. I’m new to the forum but have been using my OMTech 70W Co2 laser for a couple years. I’m wondering if anyone else has had an issue with the laser stopping after a few seconds. I was running a batch of stuff and as soon as I changed files, Lightburn said it needed to be updated (to version 2.0.02). I did the update and that was it. Every time I try to engrave, it stops after a few seconds. Nothing else changed except for the update. I’ve reinstalled old versions, rebooted everything, and n… [image] Laser jumps and does not cut the image on the cut line LightBurn Software Questions I am operating macOS Sequoia 15.5 on Apple M1 system. After installing v2.0.00 and trying to cut the laser will jump and cut a line that does not exist on the workspace? I tried multiple times to cut different images and the same occurs each time. I did the update and the same issue. I have reverted back to 1.7.08 and no issues. Any suggestions would be appreciated, [IMG_8505] [image] Has 2.1 Infected my Ruida C02 Laser? Inoperable now Ruida controllers I managed to get the machine to talk to the network again by issuing a static IP to it from my firewall and matching that IP in the controller. Now that its communicating over ethernet, the overwrite error no longer occurs. So it seems that particular issue is usb related. Can you please mark this one as resolved. I guess the underlying cause of what happened was down to old firmware on the machine conflicting with something in LB2.1.01. Since updating to LB 2.1.02 and updating the firmware,…

Thank you for the replies gentlemen. I have hesitated using the Ethernet connect because my laptop does not have an Ethernet port. Only usb A and usb C connections. I would need an adapter, not always reliable. Still don’t understand why the console panel is greyed out. Occasionally it is functional and occasionally the home button will work. I’ll get the Ethernet setup and go from there.

If you’re on your local lan and you need to be to talk to the Internet, then you’re already pretty much there. Unless you know networking, you probably don’t want to connect directly because you need to configure the port you’re using, that you don’t have.. :thinking: The other option is the Lightburn PI bridge, which is discontinued they used to sell. It does a great job of transferring data because it has a layer of software to support he Ruida. I’ve got a t-link wifi bridge that has worked for years, got it from Amazon for about $12 US. I know they’ve gone up, but still a low cost. This is mine, we have thunderstorms and the PI seems to have an issue with higher humid conditions. [bridge-router] The sooner you move to an Ethernet connection, the better it will operate. In the field, they are all networked, not usb. :grinning_cat:

[image] 1Vince: don’t understand why the console panel is greyed out That’s because Ruida controllers don’t use G-Code and, thus, do not have the human-readable interface shown in the Console. Per the doc: Users with DSP or Galvo lasers with Ruida, TopWisdom, Trocen, EZCAD2, EZCAD3 or BSL boards cannot use the Console Window to communicate with their laser’s controllers. [image] 1Vince: my laptop does not have an Ethernet port If the laser is within reach of an Ethernet port on the router or you add a Bridge, you can control the laser from the laptop through the network. Because the Ruida uses a fixed IP address, you must assign it outside the router’s DHCP range to avoid having another device get the same IP address. Some background: [image] Hello fellow laser wizards Community Laser Talk HELLO, I have a tech problem. My Omtech AF2028 stopped communicating via ethernet.

The laser IP address and the laptop IP address must be different, with LightBurn set to the laser’s IP address. The doc covers some details. If that’s how it’s set up, then we need more network information for the hive mind: 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 …

[image] 1Vince: I have hesitated using the Ethernet connect because my laptop does not have an Ethernet port. I was in a similar situation, i.e. my wifi connection was not stable to say the least, I bought a usb c to lan adapter for very little money and have been free from all the hassle with connection problems since then.

Thanks Ed. My router is very close. I made the connection but there is latency I do not have with the usb cable. Next I’ll get an adapter and directly from the laptop.

[image] 1Vince: connection but there is latency I do not have with the usb cable Do you have this latency when you browse? The Ruida can handle up to 100kb, mines on a 1gb lan/Internet and I can see no latency. If there’s a delay, it’s likely encountering a error of some type… Did you say it connected to Lightburn over Ethernet? :grinning_cat:

Yes, it is connected to light burn. Over an Ethernet cable. Is it possible? The cable. Is the issue with the latency?? I do not have. This latency when I browse.

[image] 1Vince: connected to light burn. Over an Ethernet cable You had said the laptop does not have an Ethernet port. I have lost track of the plot. [image] 1Vince: there is latency I do not have with the usb cable What are you doing and how do you measure the delay? The more details you provide, the better we can understand what’s going on …
