. Subject: Assistance with Setting Up Refox LM40 Mini 2nd Gen Laser in LightBurn

Dear guys,

I have a REFOX LM40 Mini 2nd Gen laser engraver, which I originally purchased from REWA for cellphone repairs.

They stopped giving us support for it. I would like to repurpose my laser for general engraving on different materials. I came across a discussion on this forum indicating that LightBurn has begun working on a solution to support this type of laser machine. The controller board on this machine is a DBK21B-J1-V1 with cloud capabilities for SeaCad software. I was surprised to find out that the didn’t used the old DBK21B original controller with serial port connectors in it, but a newer mini version of the card. It would have been an option for me to just swap a board to an EZCAD version.


I installed the LightBurn 1.7 trial version to test its compatibility with my laser before purchasing a full license, but I haven’t been able to get it running yet.

In the original forum post regarding this issue, someone shared a guide on setting up the laser and importing a configuration file while creating a new device in the software. However, I couldn’t find any folder containing the necessary configuration files—only an empty .cfg file.

I have tried everything I can to make it work but have been unsuccessful. Could you point me in the right direction to properly configure my laser with LightBurn?

Any assistance in setting up my laser with your software would be greatly appreciated. I am using a PC with Windows 10, and my laser is connected via USB.

Thank you for your time and support.

Best regards,
M. Adams

found a discussion on this link about the same issue, but following everything there did not give me a solution. I am still having issues with the machine—the software is not detecting the machine, and the laser is not working. BSL Boards/SeaCad



I answered you over on Reddit.

The board you wish to install is for a fiber laser, at least that’s what the user manual states…

I’d think the board would likely be incompatible with your machine.

I would advise against installing the other controller because, as Jack mentioned, the necessary connections seem missing.

But BSL-based lasers are generally supported.

If your laser is intended to be used with SeaCAD, did you use the manufacturer’s software yet? It should come with the necessary drivers.

If you don’t have this driver, you can try this one for the Gweike G2. I’m not sure, wether the controller needs another custom driver but it’s worth a try.

Otherwise, try to connect on a Mac - There are no drivers needed.

You’ll need to manually add a new device and chose BSLFiber as the device type:

Yeah, the manufacturer doesn’t seem interested in providing support. I have tried to get them to help, but nothing so far except questions that I responded and then they get silent. I also followed the manually adding machine guide, but it seems that the settings are not correct, and the configuration files that Lightburn software asks to be imported are completely missing from the root directory of SeaCad; something strange, isn’t it? So far, Lightburn is detecting the machine as BSL Garvo, and framing things works; I can see the red dot moving around, but it is not triggering the laser to burn, just the dot is moving, but the laser is not burning. Maybe it is a setting, maybe it is something else, is been a hard time. With this machine honestly. In my Opinion: someone along the way modified anything that it wasn’t intended to and messed everything up.

Why would anyone attempt to modify it?


If someone has modified it, I assume it doesn’t work at all, no laser, at least?

On Seacad software which was provided in a WhatsApp message by Refox company (Because they don’t even have an appropriate website link to download software or updates whatsoever), the journey started with me claiming to them that the software doesn’t not engrave bitmap images even though it is advertised by them. They told me that the manufacturer stopped giving support to this machine (3-4 years after release) and that they are trying to make them fix the problem, didn’t say what company was the manufacturer, so, because of the lack of support, I started doing my own research to find the manufacturer and appropriate software and whatever involves fixing the problem. I found a company named Basiliang, which manufactures these board controllers, but they do not respond to my messages. This machine originally is an engraver, and Refox company redirected the purpose of the machine to remove iPhone backglasses under laser technology. Apparently, in one of the message exchanges we had, they mentioned turning that option off because they were having issues, too. ( Not sure of the veracity of it; I believe they screwed the machine and don’t want to deal with it. They would have used a regular DBK21B controller board instead and served the same purpose intended. Btw, My board, the DBK21B-J1-V1 is an advanced version of the native DBK21B according to a company dedicated to controller boards called BSLAPP Laser China)
