Unrecognized board signature error with JCZ LMCV4 when using LightBurn

Hi everyone,

I am having trouble connecting my JCZ board (LMCV4) to LightBurn.
• Machine: Fiber laser JPT M7 60W
• Lens: 150mm
• OS: Windows 10 (64-bit)
• Board: FBL1-B-LV7 (shows as V4-Fiber-M)
• Software: LightBurn (latest version installed)

Issue:
When I connect the machine, it sometimes recognizes but often shows error:

“Unrecognized board signature: 0000238409002002”

Questions:
1. Is my board an original JCZ LMCV4 or not?
2. Does this board fully support LightBurn?
3. How to properly fix the “Unrecognized board signature” error?
4. Should I use different drivers (which version)?

Any help or guidance would be greatly appreciated!

Thanks in advance.
