Laser Tree keeps stopping mid cut

[travisnapa (Travis K.)]

I know this is like beating a dead horse…. Laser Tree AT-80W-AA AND Laser Tree AT-80W-AA Pro both run good for several runs. Then they start ending mid cut. Checked the temp and both are always cool. Not a overheat I don’t think. Stop the project, home it. start it back, and usually 30-35 seconds in it stops. Running them on a Ortue LaserMaster Pro 2. I’ve taken them down, cleaned them, and it doesn’t help. Meanwhile, my Ortur laser is over there running with no issues.

This is typically a USB communication glitch, which is regrettably so common as to have plenty of discussion:

WOO HOO !!! I got everything working right , FINELY !!! What was the problem? It turns out to be the USB to Controller board cable was faulty. That was the only thing I failed to check and that was it. I have a bad habit of buying one to use and one to loose. When I thought about the cable being bad, I got the cable out the spare controller kit and that one worked. I feel really stupid sitting here thinking how I spent 4 to 6 weeks crying and trying to fix this thing and never though…

Of particular note, long USB cables don’t work at all:

USB Cable Issue

I have just purchased a Gweike Cloud RF laser, using with Lightburn. The supplied USB cable works fine but it’s very short. So I bought a nice long one, 5 metres length. USB C to USB A, I use Macs. It’s a good quality cable, but I don’t seem to be able to make a connection when I plug in to the laser and to my Mac? Any suggestions/fixes most welcomed. I came across a really useful post by @BillieRuben who seems to have knowledge of these machines and setting up, any idea Billie ? tia

Light Burn will not run the layered drawing I have Created in LightBurn - HELP

Hello, I’m a nub to lasers and LightBurn but I have been a CAD operator for 40+ years so I the LightBurn program is not a foreign software to me. I have created a LightBurn drawing that i want to use to test my new laser and figure out power and speed for my laser. When i test my drawing by starting the PREVIEW command, the preview runs perfectly. But, when i send the send the START command to the laser, the laser starts by moving to the first object (a 1/2" diameter circle) to engrave/cut (li…

Very possible. I’m having a lot of issues with my laptop loosing USB connections. Lightburn usually won’t respond unless I shut the computer down and restart. AGGRAVATING. Especially in the middle of the of something

LightBurn depends on Windows to manage the USB connection. If that’s flaky, for whatever reason, LightBurn doesn’t really have much recourse: if it’s in the middle of a conversation and the phone hangs up (or just vanishes), there’s not much they can do.

Bonus: Because Windows can reassign the COM port numbers at any time, LightBurn may be in the middle of a conversation that will never resume.

Bottom line: you gotta fix the USB connection before LightBurn can use it.
