Assuming the test pattern ran at about the same speed as the problems shown in the first picture, it rules out gross mechanical problems. The Y axis has a slight wobble, but that may be mechanical flexing of the _heavy_ laser head on the (small) X axis bearing follower and is likely not fix-able. > [@Fabian\_74](#): > > It only happened on x axis. The Y axis has similar problems: ![LightBurn - XY axis errors](https://forum.lightburnsoftware.com/uploads/default/original/3X/7/8/785ae93272fd4718a32e1b50ca0afa5e586485b2.jpeg) The key difference between the test pattern and your design is the laser power: minimal to mark cardboard, 90% to cut plywood. Based on that, I think this is another instance of USB communication glitches, because errors / dropouts will trash parts of the commands controlling the laser head position. Higher laser power can cause both power supply brownouts and USB glitches. Unfortunately, there are no definitive tests to isolate the problem or verify the solution, so it comes down to trying a few things to see if the situation improves. Some previous discussions provide suggestions: > [@My Cherokee Beast](https://forum.lightburnsoftware.com/t/topic/107347/149): > > 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… > [@USB Cable Issue](https://forum.lightburnsoftware.com/t/usb-cable-issue/171611/): > > 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 blush > [@Light Burn will not run the layered drawing I have Created in LightBurn - HELP](https://forum.lightburnsoftware.com/t/light-burn-will-not-run-the-layered-drawing-i-have-created-in-lightburn-help/126196/): > > 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.
