EZCad 2 compactible/clone board

LightBurn Hardware Compatibility Galvo

Hi,

I recently purchase a used laser which came with a JCZ clone board, identical to the person in this post:

As with this other post, the vid/pid is 9588/9980.

I am on linux and the laser does not seem to be recognized. The shell output clearly seem to iterate over it but it does not seem to do anything with it:

Found port: PID 60000 VID 4292
Manufacturer: "Silicon Labs"
Product: "CP2104 USB to UART Bridge Controller" on "ttyUSB0"
attempting connection... 115200, DTR setting: false
attempting connection... 115200, DTR setting: true
Found port: PID 0 VID 0
Manufacturer: ""
Product: "" on "ttyS0"
attempting connection... 115200, DTR setting: false
attempting connection... 115200, DTR setting: true
...
Vend: 38280 Prod: 39296
...
Empty filename passed to function

I also gave it a try on windows 10. I was able to replace the driver with WinUSB with zadig, but lightburn still does not seem to recognize the laser.

Any tip on how to proceed would be appreciated !

Quick update, after installing and dei-nstalling the driver a number of time, I managed to get it working on windows, but still nothing on Linux.

Quick update …

I managed to kind of get it to work on linux…

When working on windows, I realized the the board start with enumerating as 9588:9980 and as soon as it is connected, re-enumerate as 9588:9899. I think the driver or software is loading the firmware.

If I first connect it to windows, then re-connect it to linux without re-starting the laser, everything works.

Does anyone have a solution to get this to work all on linux ?

Hello,

I am having the exact same issue. I have tried a fresh Ubuntu 20.04 LTS install and the newest Lightburn and it detects nothing. I made the permissions changes in udev, but the issue is the VID:PID.
I even tried running as root out of frustration to make sure that it wasn’t a strange permissions issue.

In lsusb it shows the same ID as yours: ID 9588:9980

dmesg shows:

I did end up installing EZCad on a old Windows machine and I was able to burn stuff, but it shows up in Device Manager as 9588:9899. I also tried what you suggested, swapping after starting on Windows, but that did not work for me, it still shows up as 9588:9980 in lsusb.
I see in the drivers folder that the .inf has both product IDs:
[BJJCZ.ntamd64]
%JCZUSBDEV%=Install_LMC, USB\VID_9588&PID_9980
%USBLMC%=Install_LMC, USB\VID_9588&PID_9899

I did not try the Windows version of Lightburn, since that laptop is old and out of date, so I did not want to connect it to the Internet to get the trial to run.

If you or anyone else has any ideas, please let me know. I have a fair amount of Linux experience, so I would be glad to work with anyone to try and debug this.

I already run my diode laser on Lightburn in Linux, which I love! I just bought the fiber and it would be a major bummer if I have to go back to Windows/EZCad.

Thanks

Hi Dave,

I lied a bit, when I said switching, I actually just do a usb redirection via qemu. This mean the board is actually always powered via usb.

My experience with usb is limited, but I might do some reversing on driver to see if I can figure out how the firmware loading is happening and see if I can replicate it on Linux.

I created a simple tool that extract the firmware from the windows driver and load it:

Let me know if this work for you

Charles,

You are amazing!!! I tested your script and it works perfectly!!! I am able to use my Fiber in LightBurn on Linux!

I really appreciate you responding so quickly and I never expected a solution that fast, but WOW!
I am in awe of how you figured that out so quickly and effectively.

Thank you very much,

Dave

I am happy that I help … that was actually quite fun to play with …

Charles,

It is a great help. I created a bash script to run the your Python script and then start LightBurn, which I then added as a desktop shortcut. So, it works as it normally would.

I am not sure if your fix can be incorporated into LightBurn, but hopefully this will help others in the same situation.

Again, Thank You!

Dave
