I am getting some weird wide lines on my Y axis on my 30w fiber laser. I have performed the scale adjustments so a 50 x 50 mm square comes out to 50 x 50, and I have performed the 9 point lens calibration. The horizontal lines on the X look good but the Vertical Y are funked up and I don’t know how to fix it. BTW, the company I bought this from a couple years ago, ECPUR, has disappeared, so they are of no help.
Zoom in on the pic and you’ll see what I’m talking about
I dare say it’s a loose screw, and probably on the X-axis motor pulley. Or the X-axis belt is loose.
Or am I still wrong, but I don’t think so. 
Can you post the source code.. this looks like it’s scanning the Y axes with a fill…?
A fiber laser has belts?
How do I get the code?
The .lbrn2 file that is the Lightburn project file.
My internet is down and I can’t figure out how to get the file from my laptop onto my iphone.
I’ll send it after they get the internet fixed hopefully Monday
Also, it appears that it is showing even when framing
Can’t help you with an iPhone, but I can usually ship stuff across the lan, no need for the World Wide Web to know anything.
I took another picture of the letters ABC done with line setting and 1 pass. I have checked everything I can find but don’t see any setting that would cause this!
I’m not sure what to advise you, I assume it used to work with Lightburn, leaving it as some type of hardware error.
I’ve never seen this with a galvo unless the galvo motors themselves have an issue.
You can see a definite pattern in the vertical lines.
Maybe @Albroswift can suggest something.
You did use regular text?
I believe it was ariel font. Just wanted to see what it would do. I think the problem is that I don’t have a markcfg7 file to tell lightburn the correct settings as it worked fine in ezcad. But now after installing it on lightburn I cant go back to ezcad, it keeps saying No Dog Founf
Just click on device and select your device, then edit. It will ask for the EZCad2 configuration file and allow you to navigate to it. Then just click through to finish.
The markcfg7 file lives here on my supplied memory stick.
LMA22A1095JZ/Ezcad2.14.16/plug/markcfg7
I apologize for the misinformation! 
It should always refer to the machine in question when asking for help. As you didn’t mention it, and I haven’t yet achieved the gift of fortune-telling and your profile only mentions “50W CO2” as being your machine, I assumed it could be a conventional machine and tried to help with the knowledge I have.
It really looks like it could be a bad galvo mirror/servo assembly. Which means replacing the galvo head. The servo/mirror itself could be replaced, not impossible, never tried to source one.
looks like fun to try.
Possibly though the scanning parameters are set for bidirectional and 0 degrees with bad timing settings. Please post file and screenshots of your device settings window “Galvo and Basic Settings” and the “cuts/ layers” window with the parameters you are using.
Understood. Although in my issue description I did state it is a 30w fiber that I am having issues with.
I’ll have to update my profile as well.
I have searched for the markcfg7 file and found it but lightburn doesn’t see it so I can’t import anything
Start from scratch, set up a new device and go through the steps, shouldn’t be an issue.
