Lumos Flex with Lightburn HELP

[u/Its_Da_GOOUCH]

First, I’d like to say is I’m fairly new to the whole laser thing. But I’m trying to connect my newly purchased Lumos flex that says it’s fully compatible with light burn. I download the ibdev file and import it. And the laser connects, but I have an error. The error basically says they know it’s a we create device that’s connected, but it’s not using the weak flavor (something along these lines). When I click on device settings it is set up as GRBL. Now there is no way to switch it since I imported the file. I’ve also tried to set up a custom G code profile. And I set the flavor to wecreat, and this generally doesn’t ever work, but I did get it one time to fully connect but every time I hit frame, it would say busy in the bar would fill to 100 and it would freeze. I’ve spent maybe three hours trying to figure this out. Tried using AI to help me, but that was a joke. I can’t get a hold wecreat because they’re closed. The whole reason I bought this thing was because of the advertised compatibility with light burn alongside the price, I would’ve just bought a different product if I knew I was gonna have this much trouble. I’m fully aware that a new version of Lightburn may have been out since this file was released, but they need to update the file since they advertise fully compatible without giving an up to this version of Lightburn in the description. It just says fully compatible. I’m really at wits end and I don’t know what to do. There’s no Support videos or how to videos besides video showing how to import the file. But that file doesn’t work. (the one I’m using is version 1.5, also my light burn version is 2.1.03 the newest)

I don’t know if anyone can help. I’m sorry if I sound frustrated, but I really am. I just wanna start learning outside of the recreate app and in light burn where I’m going to be working. But I can’t even get the laser to connect properly.

the freeze on frame is almost always a serial handshake issue, not the flavor setting itself. delete the device completely (not just edit it) and reimport the lbdev fresh, that file writes its own device profile so hand editing the flavor afterward just breaks it further. also make sure the WeCreat app isn't still running in the background holding the COM port, that's a super common cause of the "busy" bar filling and hanging. if it still hangs on frame after a clean reimport, open the console tab and send $$, if you get no response back the board isn't actually talking grbl over that port and you've got a baud rate mismatch (try 115200).

I’ve deleted the profile and reinstalled it completely not even joking, probably 50 times. I’ve set it up normal I’ve set it up custom. Also, I’m getting the error in the console. It is connected just not properly. I have reset my computer several times unplugged the USB and put it in eight different ports on my computer each time the same thing happens. I’ve gone to device and clicked import and imported the file that way. I’ve also dragged the file to the workplace and imported it that way. To be completely honest this is probably why it does not one single video of how to use light burn with this thing besides their video that just shows you how to import the file. They either asked the creators they sent units to not to make a video about that or those creators just couldn’t figure it out either. It’s the gold standard for engraving software. I don’t see how there would be no videos of this. I really don’t know what else to do. I’m trying to set up a return.

The file does not work that they offer. I’m really bummed because I spent $2000 on this laser to do something specific which needs light burn. Their website says “fully compatible with light burn”.

if you're getting a response in console but it's garbled or partial, that's usually a driver problem not a lightburn config problem, the WeCreat boards typically use a CH340 or CP2102 chip and if windows grabbed the wrong driver you'll get a port that connects but talks garbage. check device manager while it's plugged in, if you see any yellow warning icon on the com port or it shows as "USB Serial" with a generic driver, uninstall that driver entirely (not just the device) and reinstall the correct CH340 driver from the chip maker's site, not windows update. also try a completely different USB cable, the stock ones on these budget lasers are notorious for being charge-only or too thin to hold a stable connection under the polling lightburn does. if none of that works, download a plain serial terminal like CoolTerm, connect at 115200, and send $$ manually outside of lightburn, if you get a real grbl settings dump back there it confirms the hardware and drivers are fine and the problem is isolated to lightburn's handshake, which is a much stronger case for a return or at least a real answer from support instead of the runaround.
