Framing using a Galvo Laser is larger than the size of the image

I have an image 86 x 54mm. The dimensions are set correctly and scales correctly in the LightBurn working ares. When FRAMING is selected, the framing dimensions are much larger.

If I change the image size to 69 x 42 in the Width/Height fields, the image Frames correctly. This is obviously wrong, what is the fix please.

Sometimes there is an entity there, that’s not visible…

You should be able to select all (^A) and then zoom to frame selection (^ + shift + A). This should capture all the objects… The ^ is the control key.

Does only the image show selected?

If you hit F3 in LightBurn, you can adjust the sizing, position, etc. of the Red Light for Framing in this area:

Following along, does it burn the correct dimensions?

That might be a solution. When I installed LightBurn the file markcfg7 was never used or asked for. I am using version 1.4.05 and there should be a way of loading the Factory Calibration Settings manually. I did Double_Click the Device type and was asked for the config file, but it never stated the name of this file, so I guessed it was markcfg7. Then I got “Unable to locate specific COR file: E:\jczEZCAD for ComMarker B4\110mm\jcz11.cor. You will have to manually load your COR file in Device Settings”. I am going to need help with this task. I am still not sure why this is not automated in the Installation Manager.

Yes, the steps you went through are to load the markcfg7 file. It’s annotated at the bottom of that screen

If you have a .cor file to load, that’s loaded in the F3 page here:

I have hundreds of files. Can you advise me of the file extension, this would help in locating the file. I do see a CorFile2.exe but I dont think the cile will be an executable.

Cor files produced by EZCad2 software has a .cor extension. The markcfg7 has no extension.

On my supplied EZCad2 memory stick they live here…

LMA22A1095JZ/Ezcad2.14.16/plug

These were supplied on my machine, only used markcfg7 file

Where did cile come from?

OK. I received the new files from the supplier, loaded them into LightBurn, did the square test on black card again and it scaled perfectly. I thought this would be the end of it, but now quite. I imported a png file (which is defined as an image) and it all looked OK on the LightBurn worksheet. Unfortunately, when I lasered the image, no part of the image was filled, just line was used.
Then I notices something else. If I Imported any type of file and did not change the scale of the image, it framed OK, a little small but OK. If I changed the dimensions of the scale, the Framing was way off and no amount of scaling would bring it back. It look to me like there may be some math issue. Can somebody verify this for me please.

What new files?


The correction files are dependent on the lens, as each is different… What files did they send you?

If it’s a config or cor file, you have to have the machine and lens to create this…


I know I can’t use a file created with a different lens…

Yes, I know this. I received files for both of my lenses matched to the Serial Number of my machine. The lager cut is now exactly square. The issue now is when I draw a square on the Job Area of LightBurn, it frames 116mm x 116mm and not the 100mm square I drew. I presses F3 and found on the top right some scaling parameters. When I changed the scale from 1.0 to 0.862 to see if this fixed the issue, but there was no change…any advice please.

I think you’d be wise to ask your vendor for help as they know the machine much better than we do.

If it’s a new machine it should work out of the box without all of this extra fiddling.

I don’t know what to advise at this point.

You profile doesn’t give us much to go on as to the type of fiber you have. At this point I don’t know if that will help.
