I just bought a Creality CR-Falcon 10w laser and am having a problem with it losing communication with the computer. I’m using Lightburn 1.4.04 and I’m not sure what’s causing it. I have an Xtool D1 laser so I’m doughtful that the USB is sleeping but my laptop is set to keep the USB from falling asleep. I saw a video about static electricity might be causing it but when i check the ohms for a grounding issue but my meter was reading “OL” so no static electricity happening.
I think it has something to do with Lightburn intermingling because when I change from one to the other the speed/temp setting are changed. I have a material list for the xtool but can’t find one for the CR Falcon, Can’t find much of nothing on the CR Falcon, and the xtool material list always trys to load but can’t.
Now I did read somewhere that people have setup 2 different links to start up Lightburn totally separate from each other but didn’t explain how to do it. Does anyone else have/had this problem? If so and fixed can you tell me what to try?
How were you testing this? If you were testing continuity to ground then an OL reading would mean it’s not grounded.
I’m not following this. Can you elaborate? Intermingling with what?
If LightBurn is working reliably with the xTool then it’s almost certainly something unique with the Creality. Try changing the USB port to the one that works on the xTool. Does it work reliably then? When you test, are you testing with both lasers connected? If so, try testing with a single laser and with the laser connected to the port that the xTool is currently on.
It’s very likely this won’t resolve the core issue. There may be other reasons to do this but resolving the communication issue is probably not one of them.
When I switch from my D1 to the CR Falcon in Devices, I have Xtools material list try to load which, when I switch from the Com port the D1 is on, shouldn’t that material list not be agonized on my Falcon Port? This is making me think they are interacting with each other. Sort of listening to an old AM radio were your listing to a station and another station bleeds over (sort of showing my age. 60’s radio brfore FM).
The d1 was working properly before I added the Falcon. Now what I noticed is now my D1 isn’t printing, running, but not printing. So I stopped it turned of the D1, switched to the CR Falcon, tried a print and now it’s doing the same thing. Right now I’m checking and cleaning the D1 laser lens which is clean actually, and the lenses aren’t cracked so the drop in power doesn’t make sense becasue its happening on both lasers. By the way, the speed power setting is 800SP & 70 P so it should be doing a seeable burn but nothing.
LightBurn will default to the existing Material Library unless you specify another one. Once you specify another one for that device, it will bring up the Material Library associated to that device.
S Value max? I looked on both the file setting and Display and Units and I don’t see a S Value. However, I did recheck the static electricity and I do have to ground it. Although I’m not sure what I need to ground. I know it would go from the laser to the gentry then the front but I’m not sure where to ground it from there and Creality don’t have anything on a grounding kit or something.
You are likely looking at Edit->Settings rather than Edit->Device Settings.
For grounding I’d take a look at what Ortur provided. They had an issue a while back and took good care of it. Should give you an idea of what to look for.
Primarily you want to make sure that the laser module is grounded to the chassis. That itself might be enough to resolve the issues. But if you want to take it further then ground the chassis to the center retaining screw of a power outlet. That should be sufficient even if the retaining screw is improperly grounded.
Do you notice issues more with fill or images than with line operations?
I watched that video on the grounding problem but there are a few differences. The CR Falcon doesn’t have a limit switch to wire to and I don’t have any open outlets to wire the ground to. I’m trying to think of where I can ground it.
