CZFiber unrecognized board signature 0000238409002002 - framing broken on ComMarker B6 60W MOPA

[sipple13 (seth)]

I have a ComMarker B6 60W JPT MOPA fiber laser running a JCZ/BJJCZ controller. LightBurn connects and I can engrave successfully, but framing is broken — the red dot only moves in a single straight line instead of tracing a rectangle around the design.

Status bar shows: Unrecognized board signature: 0000238409002002

Tested on LightBurn 2.0.05 and 2.1.00-RC-11 — same issue on both.

Setup: ComMarker B6 60W JPT MOPA, 150mm lens, JCZ/BJJCZ controller, USB (LibUSB), macOS, device type JCZFiber | Galvo

Can you add board signature 0000238409002002 to the recognized list? Everything else works fine — just framing is broken.

Wanted to follow up and also flag a related thread with the same board signature issue on a ComMarker Titan 1:

Unrecognized board signature 0000238409002002

Just got my ComMarker Titan 1 60W MOPA setup and am having issues getting it to work in Lightburn. I have removed the Ezcad2 USB driver and installed the Lightburn driver and am seeing the above error message. Found a few other posts about this but nothing suggested helped unfortunately. When I try to frame by clicking the frame button the laser immediately starts framing. If when I click the start button in the framing window framing stops completely. sometimes the program freezes and I have t…

In that thread, Colin confirmed LightBurn is aware of signature 0000238409002002 and plans to add it in a future release — great to hear. Just wanted to connect the dots since it’s clearly affecting multiple ComMarker machines (B6 and Titan 1 at minimum).

Any rough idea which release this might land in? Hoping to avoid EZCad2 as a workaround. Everything else in LightBurn works great — just need that framing rectangle back. Happy to provide any additional info or logs if it helps move things along.
