Is there a way to stop LW from making a raster Gcode the full

Is there a way to stop LW from making a raster Gcode the full width of the file, I only have this problem once in a while but I can not shake it. As you can see both files are rasters and both have burn white turn off. I have saved both files as jpeg. Clearly this is increasing my job times but I wonder if there is something I’m missing.

I think I have suffered this before but I suggest you use another image for the second option as that example does not show what could be going on

try bumping the min power to 5%, that may be including the white background of your image. or crop out the trees and re-save.

Try a low value in the contrast field. 1 or 2 seems to do it for me.

@Ariel_Yahni_UniKpty ​​ sorry I should have explained the second image is just a 90x 9mm black rectangle on a white background. There is no reason I can see why it would raster the whole image.@Domm434 ​ if I raise the minimum power up it will then burn the white surely as this will be the lowest setting for the laser and not 0.

This is mostly caused by the white not beeing real white, but light grey. By increasing contrast and brightness (in LW Operation) you should be able to correct that.

That’s going to be my next test later when I’m home but why would this happen if both backgrounds are set to white in Photoshop when the files are created. Is it just a glitch somewhere in the processing of it?

This might be a bug, but it works if you just increase the brightness or contrast by 1. (tested with Illustrator jpg)

Ok thank you@cprezzi I will adjust it later and try again.

I know it works, I do this with almost every JPG that I generate from Illustrator or Corel Draw. And it definitely makes a huge difference in engraving time

Update: increasing brightness and contrast to 1 does correct all the images I have had problems with. I will have to make a mental note on this one and change it accordingly in the future.
Thank you @cprezzi @Kelly_Burns @Ariel_Yahni_UniKpty once again you do the community proud.

Use gimp to remove background and save as png with transparent background.
