I cannot get lightburn to recognize my laser. I have follower the instructions, and lightburn says it is disconnected. I can install as a bsl laser instead of a jcz type, and i have limited functionality, but if i choose jcz fiber, it will not connect. anyone have any ideas?
Did you have EZCad installed before?
You may need to perform a driver swap in order for LightBurn to talk to your laser. Follow our documentation here on how to do that: Galvo Driver Installation - LightBurn Documentation
We also have a video showing the process here: https://www.youtube.com/watch?v=YbzSO20bSuA
Finally, if neither of those methods works, try doing the Zadig driver swap, as explained here: Zadig Driver Swap
Please let us know if you have any trouble after the above methods. If the driver swap doesn’t work, typically there is an issue with the physical connection path between your Galvo and your PC.
I am having the same issue with a Monport 30 watt laser and have done all that was suggested. It still will not connect.
Did you ever get your laser to connect?
Yes, I did finally get a response. they are using a new driver, and it is connecting as a BSL fiber laser. I have a video they sent me, no sound, just install and configuration. it is using they cypress driver, I can email you the video if you want it.
Did you check how your laser work? Text, images? Any strange things?
Software they provideed with machine is BSLCad?
Hello michaeldein,
I have the same problem,
could you please send me the video?

greetings stirlitz
I apologize for the delayed response. I have spent many hours now figuring this out, this is actually a decent product, although the customer service leaves something to be desired. Please email me at michaeldein@yahoo.com and i will forward you the video I was sent, but I can sum it up here.
The back of your laser will have an identification plate showing several pieces of data that were recorded at the time of manufacture. This will include things like galvo 1 and galvo 2 offset, trapezoid, galvo 2 is x, q pulse width, hertz bandwith, and many more. These are all variables that are able to be manually inputted into the settings in lightburn If you are unable to import them. All of these settings are on the usb drive that was supplied with your order. I can also explain how to calibrate the rotary function if you like, I found 12800 steps per revolution works for me, but as all machines are slightly different, use these as starting values when dialing in your machine.
cheers!
@michaeldein Thank you for forwarding us the Monport instruction video.
The important part is installing the Cypress drivers. Did you receive these on a USB thumbdrive?
I was surprised to see that they did not import a config file when adding the laser. (LmcPar.cfg or BslCAD.cfg) This file is usually located on the USB drive, in the BSLcad or SeaCad application folder.
It would automatically populate all these settings. Galvo settings can’t be found through trial and error, due to the complexity and variety of machine configuration. Settings that work on one laser may destroy another.
