New user here, sorry if this has been posted. I look around and found nothing that helps me.
I create a square in Lightburn 2"x2" and the box is much smaller than that. My red light and the marking are perfectly together, but the box is much smaller than what Lightburn is saying it is.
I believe this may be caused because I didn’t upload my COR file, but it doesn’t show up when I try and load it in Lightburn. It only shows up when I look in my folder.
Another issue I’m having is the image being stretched out while using the rotary. I drew a line on the chuck of the rotary and ran test, it does a perfect 360 one way and back. So, I don’t think it’s my steps. Maybe it’s the same issue?
It isn’t going to work properly without a lens correction file… This tells it how far away the lens if from the table and other peculiar attributes of the lens itself.
Your fiber should have been shipped with a markcfg7 file for your lens.
This can be loaded when you create a new device…
Mine was on the supplied usb stick here…
/LMA22A1095JZ/Ezcad2.14.16/plug/markcfg7
If you want to use a cor file, you have to assign it via the Device settings .
Thank you for taking the time to help! I have the Cor file, but it must be formatted different because it only shows up in my ezcad folder and not when I try and load it in Lightburn. I’ll try and track down my usb stick that I received with the laser. As far as the lens I bought, it didn’t come with anything. Is there a way to manually do this?
Click on Import EZCad Config. Select the markcfg7 file.
Click next through finish.
This should update it to the EZCad configuration.
A cor file is filename.cor, the one you pointed out is the executable to create them.
These are my cor files… The F420 was the supplied lens, so I didn’t need the CoreFile2 software.

Do you have only one lens, that came with the machine?
Deal with one issue at a time. This may get fixed when you find the problem.
If it’s a new machine, I’d be in touch with their support group. So make contact with them asap.
I don’t know how these markcfg7 files are created. I have no way that I know of to create them. I think that’s why they have the EZCad CoreFile2 software. When you get a new lens you need a correction configuration. You can do it manually or via software… I’d suggest software, it’s the least painful…
The new 1.50 version of the beta public release is out. I believe it has an entry in the Laser Tools → Lens Calibration…
If not, you’d have to run the CoreFile2 software…
There are manual ways to do this, you can find them on You tube but I’m not doing that.
I still think your vendor should be responsible for handling this.
Thank you so much for this information, I just downloaded the update for LightBurn and see this new option! I’ll be trying this out today. I’ll update this post if it resolves my issue to help anyone else that may have this problem as well.
BOOM! You nailed it, the video you sent me corrected ALL issues. Thank you so much! Image was stretched on the rotary because the lens needed corrections. Now when I make a box in lightburn at 2" it marks 2"
.
I’m not sure what else to do
