I’m struggling getting my laser connected on a different computer - Ethernet.
I’m moving some computers around the shop. On the machine I moved to the OMTech Maker CO2 laser, Lightburn is not connecting to the laser.
I’ve been using an X1 Carbon Gen12 W11 Pro machine since I set the laser up. The connection was easy-peezy and it’s been reliable for me.
The computer I’m trying to set up now is an X1 Carbon Gen11 W11 Pro machine - so very similar. I exported a settings and laser bundle from the working computer and loaded it into the new machine.
I can ping the laser. IPCONFIG looks the same on both computers. The laptops are on wifi connections. The laser is plugged into the router.
I changed the IP address on the laser to see if there might be a conflict. Pinging the old IP address did not return anything. I set the laser back to the original IP. I searched this forum before posting and saw one thread that said Ruida controllers only support 255.255.255.0 subnet address. Mine is 255.255.252.0 … but the one computer has been working fine since day 1, and still connects. I can change our network to 255x3, but that doesn’t seem to explain the issue since the original computer has been working all along.
I checked firewall settings and Lightburn is allowed through the firewall. Also tried a DNS flush as well as a renew.
On the computer that’s been working, Lightburn shows READY as soon as i open it up.
The new computer shows disconnected. Google has told me I can right-click on the DEVICES button to reconnect, but a right click does nothing for me.
Not only that, the IP address of the laser (my OMT-60W 400x600) is 192.168.1.100. and assigned permanently, according to the manual.
I have a small switch that is physically connected to my LAN, which is connected via cable to my laser. I access this laser with 3-4 computers, 1(2) with cable through the switch the other computers over LAN via Wifi.
(I periodically do some tests with 3 different OS, hence the number of computers, on a daily basis I “only” use 2 computers.)
It is a slightly older OMT I have and it is possible that things are more flexible with the newer machines. Here in the forum there are also some network experts who may have another good explanation how your problem can be solved.
On my controller I can set the IP and the subnet, so the .255.0 limitation doesn’t seem to apply here. Also, it’s been working for 2 months on another computer - and still works on that one.
If the “new” PC’s IP address differs from the “old” one in the third octet, then it will be invisible to the laser controller.
For example:
Working IP = 192.168.1.5
Failing IP = 192.168.2.5
If the PC’s IP addresses get assigned by DHCP and you can’t control those assignments, then the “new” PC may work some days and not others, depending on that third octet.
