Hello, I’m having trouble migrating my CO2 laser galvo system from Ezcad to Lightburn. I’ve tried on both Linux (Xubuntu) and Windows 11, but Lightburn fails to recognize the laser control board in both operating systems. I’ve successfully performed the same migration process on another machine and computer without any issues. I’ve searched the forums for solutions, but I haven’t found anything helpful. I may have overlooked something. Can you assist me?
Attached is an image showing the name of the card as recognized by Windows in the previous installation (Ezcad).
Yes, it should work with Ezcad using the same drivers as another 64-bit Fiber V2 machine. I used to have an old fiber laser with a V1 board, but it had its own drivers and was only for 32 bits.
I have attached images of the device manager in Windows (where Ezcad works) and the lsusb command in Linux. In Linux, I have highlighted the two devices that appear when the machine is connected.
I tested it on a clean Windows installation and Lightburn also did not recognize it. Please note that this is a CO2 tube machine.
I apologize for my poor English and I hope for your help, I would really like to be able to use Lightburn on this machine as well.

It’s the BJJCZ USBLMCV4 entry. I’ve never seen that ID, but I’m sure that applies to more than this one.
I was asking about EZCad2, which is supported by Lightburn compared to EZCad3, which is not.
I know on Windows, there isn’t a driver that will support both Lightburn and EZCad2.
Might be wise to ask for help here… maybe @JohnJohn could clarify if this board is supported or not.
I’ve tested the board on another Windows PC with installed Lightburn drivers, but it didn’t recognize the device. I’ve also tried using Lubuntu and Ubuntu on Linux, even though there shouldn’t be any difference in terms of driver compatibility. Occasionally, the device is listed as “BJJCZ USBLMCV4” when using the lsusb command.
Yes, it is listed with BJJCZ on a computer where the machine is running with EZCAD. I only used it for illustration purposes. I tested it on another Windows installation with Lightburn drivers, including this same one that recognized a Fiber Laser without problems, and a clean Ubuntu installation, Lightburn did not recognize it in either case.
I am migrating the equipment to Lightburn and this is the fourth machine. The previous ones were very simple and only needed the specific adjustments for each one, but we have to have this one with an unsupported board.
Hello, until today we did several tests on different OS (Windows 7 32 bits, WIndows 10 and 11 64 bits, Ubuntu 24.04) and Lighburn didn’t recognize the machine, I rolled back the drivers, tested on new OS installations and nothing . Could it be that the controller is a similar/unofficial JCZ model?
If I understand correctly, the drivers you indicated there are for Ezcad, I had no problems with it, I can’t get Lightburn, with its specific drivers, to recognize the machine.
Apologies for not seeing this sooner. Do you know how old the board is? Does it work with current versions of EZCad2?
If it uses a different PID/VID pair to identify it, there’s a good chance that the protocol used is different, but without a data capture from the board I couldn’t say for sure.
Hello, it works on current versions of EZcad2, I have no idea how old the board is, but it is a machine that was assembled in 2018, at the time I had much less knowledge and didn’t participate much in the construction. Thank you for your help and ask me for any information you need.
Exactly, the system recognizes the control board but Lightburn does not, I hope the team can help me as it is the only equipment that I still cannot use Lightburn on.
This archive JCZDriverAllInOne.rar.txt (1.4 MB) has a LMC V1 pointer in file JCZLMC.inf.
Maybe on Win10 you can manually force the installation of this driver…(or force the one from Win7 although 32bits)
.
Or if you´re ok with electronics:
Hello friend, but are these drivers in the link for Ezcad? It’s working without problems, what I want is to use Lightburn, and its drivers are not recognizing this control card on any OS, I tried it on Win 10 x64 / Win 7 x86, Ubuntu 24.04
There won’t be anything you can do to the drivers to make it work with LightBurn - The USB device itself is what tells the system what its device ID is, and LightBurn is looking for specific device IDs to connect to.
When you connect this board to the PC with EZCad drivers installed, do you hear only a single “ding” from Windows, or do you get two of them in a row? (I ask because with a number of clone cards, the first ID is used to tell the driver to upload some firmware to the board, and that one changes the USB ID, which Windows responds to with a 2nd tone)
