I have a Longer Ray 5 which i want to control via WiFi and Lightburn. I have already added the laser to my Wifi and am able to control it with Longer’s Laserburn App on both my phone and desktop computer. However, after adding it to Lightburn as a GRBL laser via TCP/IP and specifying its IP address, i only get “Waiting for connection…”. This happens on both my mac and my pc, while i am easily able to control the device via laserburn from the same mac.
Of course, i made sure that no other application attempted to connect to the Laser while trying Lightburn, and also made sure that the mac can ping the laser at all.
Since it also happens on a windows machine in the same LAN, and the LaserBurn connection is successful, i think this has to do something with Lightburn itself. Am i missing something here?
Usually, you need to change the port to the correct one in device settings. Most lasers use 8080, while LB sets 21 as default (if I remember correctly, could be a little different).
Thanks, this was a helpful hint. However, the next question arises directly from that. I did a tcpdump to verify that LaserBurn actually connects to the device via port 8848/tcp like the manufacturer says in its documentation.
However, on that port, a WebUI “ESP3D for GRBL ESP32” shows up, and Lightburn cannot parse the HTTP content sent by the device. Some searching inside the settings of this WebUI does indeed say that the Telnet Port is 23 and should be enabled, but it can’t be port scanned by nmap, though.
I am not sure what Longer did there, and since i am a bloody newbie, i could need all hints i get.
No success on all the ports you listed, unfortunately. Since telnet on port 23 is clearly shown as enabled in the WebUI but not accessible, i have contacted the manufacturer for additional support. At first i thought this is a Lightburn issue, since LaserBurn is connecting fine (on port 8448 though), but it turns out that LaserGRBL also has connection issues.
But it turns out, it is more a device problem than a Lightburn problem
Try 80, 8080, 8081 and 23 first. Then you might check for others.
