I have an image I’m trying to engrave but when I send it to my laser, the red dot just goes back and forth not burning or moving up.
What did I do wrong?
Max 50W fiber laser
Black and white image.
Hi Philip
Can you post a Screenshot of your settings.
Now the preview shows this. Should I change back to an earlier version of LB?
I just can’t figure out what changed from yesterday.
I dont know how fibre lasers work philip but all I see that looks off to me is the 100mm/s.
If the laser is firing but nothing appears to be happening then it might be scanning to fast to be effective.
Thanks, but actually, it’s now burning but only across the very bottom where it shouldn’t be burning because that part of the image is dark to black.
These are flat white/flat black painted slate coasters.
As I said, these same settings worked yesterday.
Are all cables seated good…Would a restart help.
Settings and software worked yesterday so will/should still work today.
Are you sure? 100mm/s @20% is the default Lightburn setting.
I restarted everything. Didn’t help.
That’s correct except the 50khz.
Philip, Have a read of this post and see if its a similar situation.
Whatever the reason, it’s working now. I opened the image from the linked post and played with it for a while. Then I opened my image back up, tried this and that and it’s working. 100/20/50 is the number.
Thanks everyone.

Geez, once again it’s doing it, not showing in the preview. I do see very light portions of the image in normal and inverted.
This is a contrasty black and white png image, similar to the previous one.
It’s going on flat white/flat black painted slate. What should used to engrave this? The global settings (I think that’s the right term) and not speed/power/freq.
Sorry to keep asking this but it keeps happening. I could have sworn it’s the same as last time. I engraved the last one and went right to the next. I did save the settings in the library.
Thank you.
Hey Philip
For slate in general you can use a negative of the image to have it appear like the original image. slate engraves brighter..not darker.
The 'global settings? not sure what that is…is it a pre-set for slate, from the materials library or something?
So, some of the brighter areas of your image are visible and the blacks aren’t Jet-black…I’m thinking that means something is there but the image settings aren’t allowing it to show…just a guess…is/are any setting too extremely high/low.
Can you screenshot the image settings and preview.
By the way…what did you adjust that got it to work last time.
Is it still scanning across the bottom? burn/no burn?
I think we need to rule our either ‘settings’ or ‘connections’.
When I said ‘global’ I meant the settings that are always used with slate. I know I’m wrong but couldn’t think of any other way to say it.
If I knew that, I wouldn’t be here bugging you folks. I thought it was the same as previous.
I’m not at the machine right now, but this is the image I’m working on. The preview is showing a mostly while square. The are a few very faint parts in the corners but white.
So, if I load this 300 dpi .png image as is, set my spd/pwr/freq settings, what else? Do I click 'negative image"? Which I did in my trials but no help.
Anyone want to try the image?
I’m just confused.
Thank you.
Philip
Dark areas in your original image will show up as Back/Darker areas in preview.
Bright areas in the original will show up as White/Brighter areas in preview.
Pink/Red is the traversal lines of the laser head movements.
Do you see any Red lines on the preview.
If you click the INVERT button (to Green) in preview window the colors should reverse..Then switch it back again
Can you post a screenshot of your Preview window and image settings?
To make a preview picture (Right hand side) all white, I have to have the Brightness setting all the way up and that means I cant see the picture on main lightburn screen… the original image is only visible in preview (on the Left).
So try
(negative picture OFF) in image settings.
(Invert OFF) in Preview.
Image settings sliders in the middle so you can see the image normally, and try to engrave that on some scrap material…just to know it is all working ok.
I found the same thing in the latest release on my xtool s1
The answer for me was to leave lightburn open, turn off my machine and then turn it back on again. After that it was fine all day. But once i rebooted my pc the following day i had to do the same again
Worth a shot, thanks.
