- Fix Your Blurry Engravings | Lightburn Scanning Offset Adjustment
Blurry engravings, sloped edges, and double images in an engraving are all signs that you likely need to set up some scanning offsets!
Follow the steps of this video and you will get you engravings in tip top shape!

Great video.... I was SURE this was my solution and when I got up someone in the Lightburn forum simply said "tighten your X belt" I went and double checked and yup! There was play...which gave the head SLOP in each start right and left... Your offset fix might have compensated for that and adjusting for different speeds might have compensated for increases torque at higher speeds.
Your solution might be the fix for some, even most with this issue but i wanted to share my experience in that it might save someone else HOURS of troubleshooting and settings adjusting.
Can you do a video on how to tighten up all the nuts and bolts and also how to tighten the belt?
I knew the settings would be there somewhere and I new I had to do it 😀 I finally had a job that needed small letters engraved into acrylic and was getting crappy results. After this, its sharp edge's all around. Thanks for the vid 👍
Glad you got it dial in! You’re welcome!
thank youu! from Argentina
Very helpful never knew about this issue
Just got a new co2 laser, this video saved me so much troubleshooting time
Glad it helped!
My guy, I owe you a case of beer. You are a life saver!!!
🍻🍻🍻
I followed along with your video and did as you did but it did not correct mine and you did not go into what happens if it does not correct the issue . so how do you correct it if it is not correct ??
Why would double lines happen all of a sudden though? If your machine was engraving fine one day, why would it just go off center the next day if its a software issue?
Have you checked your beam alignment?
Ive had my machine for 2 years now and I finally took the plunge today and aligned all my mirrors. It was always a fear that I would mess up something and wouldn't be able to cut or engrave anything. Had to get over that. I aligned the mirrors and did the offset configuration and wow....the difference is night and day. Thank you for making these videos. Wish I could subscribe a million times!!!
You’re welcome! Glad you are seeing the benefit of fine tuning your machine and getting awesome results!
Very informative thanks
You’re welcome!
Great video, do these settings live in lightburn or are they uploaded into the firmware somewhere.
Do most machines come with offsets this far off? Those are some pretty huge offsets it seems.
Looking to get into laser cutting (10 year 3d printing background but new to cnc / laser) with a monport or an omtech 50 - 80 watt mid tier unit.
Thanks for this video!!!
You’re welcome!
Hello! I was looking for a video like yours, because my laser engraving and cuting has been like shit in the last few days and I can't seem to find the main problem. I did all the stepts in the video (I'd already seen the tutorial in the Lightburn page but it wasn't so helpful), and I find that my main problem is with the lines, even with this test, the lines are always "blurry", so I understand that my problem is not from the engraving. How can I fix this?
If the lines are thicker than you would expect then it is likely that you are not focused correctly.
So, Lightburn will take into account these numbers you entered as long as it is enabled. You use speed of 100, 300, 400 and 600. What if you go 200mm or 500 mm speed, does Lightburn will average these numbers, I mean between 100mm and 300mm and between 400mm and 600mm, or you have to do it for each speed you use.
Thanks for those great videos.
Lightburn will make adjustments for the speeds in between. If you see that something is still not quite right then you can add another speed entry to the mix.
@@BeardedBuildsCo Thanks for the reply, really appreciated, Jeff
@ostie01 you’re welcome!
Thankyou for this simple to understand video hopefully I can get crisp engraves on rubber! Can I just ask when I do embossed design so that the laser engrave the spaces between my design will I see less nasty engraved lines around the rubber engraved image, they look rather like ribbed pattern as in the line tests you show......hopefully the area not embossed but debossed will be smoother?👌
You need to test different line intervals, powers, speeds, and focal heights to get the look you like best.
@@BeardedBuildsCo Ohhh do you have a link for testing line intervals? I will do the test grid with powers and speeds & hopefully if I measure the material I can add in the 17mm minus the thickness of the material for focal height? Do this line test that you suggested first though or which order to do them in. I had exact measurements and focal distance for my rubber when the red and black 60 watt was working given to me when taking over the business so this is all new to me!!
@LouiseHolmanClarke you can test line intervals with the material test generator in lightburn.
I also have a full course on lightburn, its features, and usages.

@@BeardedBuildsCo Thankyou Ok I will bear this in mind in the future but for now I have a show in two weeks so I need to learn just what I need to know this week to engrave my stock! 😨
Do you have to do for every speed you use or will the software average the data and do that for you? ei, if you use 380mm/s will you need an offset for that or will is use the date from the 300 and 400 that you have input? Thanks for a simple and step by step explanation
You will want to do at least 3 speeds possibly most of you still see signs of an offset. If you use 380 I would do 200, 300, and 400
I did 100 200 300 400. they came out even no offset..weird???
Once you enter your measurements, would you "write" to the controller? the version of Lightburn I have has this as an option and I don't know if I need to hit it or not. I'm assuming I do.
Usually when you are doing this there is not a write to controller option. The software drives these settings
Also you mentioned these settings saving in Lightburn. If you have RDworks as well connected can they be saved their as well?
Why would you use both? You can export the settings and just save them.
@@BeardedBuildsCo just because I am used to using RDworks to load my work from coral draw?
Are these offsets consistent on both x and y axis?
The offsets are no specific to the axis it applied to the machine as a whole.
this may sounds silly but when you added the box around it, I'm assuming that was just a "line" not fill correct?
Yes, just change your same box that you used to the test to line.
@@BeardedBuildsCo Thank you for this video! made. such a difference and it was all explained. in a simple way to not overwhelm!
