is there a err log file or anything? I will help in anyway i can short of formatting my pc 
I would just check your network router and settings to make sure that nothing in your network config has changed, and your laserâs IP address isnât being reserved for anything else on the network. Iâve seen this happen before if you donât tell your router to reserve the IP address used by the laser, and you donât have the laser IP address set far enough apart from the others on your network.
My best guess is that anything small enough to fit within a single packet of data (1000 bytes) is going to work, but anything larger fails, but I couldnât tell you why.
Youâve said âEthernet connectionâ - wired or wireless?
wired ethernet, nothings changed in a few years netowrk wise, but i will reboot all networking switched and routers, (there is a bunch) but the laser is on the main switch, as well I can read the settings from the laser, jog the laser, stream to the laser, delete files from the laser. just not send to the laser hmi but rdworks can.
Go to Edit > Device Settings and try increasing the network timeout. Itâs possible that itâs just not waiting long enough.
just increased, now it just sits longer before it errors out.
any error logs?
you are on to something, that test file i imported, if i send one of the small circles it will send, if i try to send anythign more complex or larger it errors out
Go to Help > Enable Debug logging, then try sending something. If it errors, itâll show there, but there may not be much info. Usually when I see this problem itâs just the network dropping a packet. Do you have more than one copy of LightBurn running, by chance?
just one copy, this all happens at fresh reboot as well, where is the debug log located? i enabled it and did a run through
In your Documents folder, called LightBurnLog.txt.
Post here and then delete the file locally. If you run another log it will append to whatever is there.
Did that one fail? It looks like that was successful.
the larger one is a failed attempt,
LB will create the file name on the HMI but when i go to the HMI it shows the name but no art, as well LB shows the file transfer failed
By chance, did a recent Windows Update modify your NIC driver or settings? If you want to see what occured in recent Windows Update, you can open up PowerShell (as an Admin) and use the following command:
Get-WindowsUpdatelog
When you run this, you will see where the file can be found, opened, and read. You could search for key words maybe (like network, or your NIC name etc)âŚ
So it is the NIC for some reason i cannot figure out yet, This mobo has dual NIC, I plugged the laser direct into the second nic changed IP accordingly 192.168.2.90 etc, and bingo i can now send, so as usaual LB is sound and windows is NUTS!!
Thatâs bizarre. Looking at the logs, the only clue is that the failed job is not getting a reply from the laser, but there isnât anything else thatâs much different. The first job sent 1100 bytes total, and the second sent 1472 and failed. Is it possible that something lowered your MTU?
I experienced similar after on of the recent upgrades. I found that Lightburn was sending, but was sending no content in the upload because my output selection was turned off. In the âCuts / Layersâ window pane on the right, the green or greyed out toggle was turned off on each layer. This âOutputâ column is to the right of âSpeed / Powerâ and left of âShowâ columns.
This could have been an operator error in a hurry and wild clicking or may have been a config change due to the upgrade. Anyway, I clicked to turn âOutputâ green and the send feature worked perfectly when it actually had something to send. Good luck.
