I am pretty new to lightburn but had made a few things so I have used it a little. I was asked to make a sign for someone that was larger than my laser bed. I created the design and split it in two by watching videos. I added bullseyes to the outside of my design to line up my work. The 1st part burned great but when I went to burn the 2nd half it was off by the a little. After much frustration and ruing a couple of pieces of wood I figured it was the registration marks that were being calculated into my work piece. I was able to get a good burn on both halves by deleting the bullseye from my design and lining it up with my a tape measure and my eye Is there a way to make it so the bullseye do not get calculated into the width of the design. I did another test and added the bullseye inside the design and everything framed out good. I know there is a way to do this without the extra steps so any help would be greatly appreciated.
Pictures really help us understand what you’re trying to achieve.
Are you usnig the print and cut feature? If so, one thing is make sure you choose the not scaled option. It took me a few times to get it working correctly. It was all user error and not totally understanding how it is suppose to work. I watched several videos from different people to understand it.
Instead of adding bullseyes you can use parts of your design as the targets although that depends on font choice and other design elements. You need a definite point to target onto like a point of a star or the corner of a letter as long as it’s not a rounded font.
Another thing is you want to have your targets as far apart from each other as is possible.
I used a piece of tape to burn targets on and incorporated into my design so it was within the limits and could peel of the tape when done. This worked. I was just wondering if there was a way for lightburn to not calculate the bullseye if they were outside of the work piece.
Thanks for the quick response.
Not sure what you mean by not calculating the bullseye. It has to fit within your work area. Pictures would probably help me understand.
Sorry but I deleted the project after I ran it. But I did figured out how to make it work. Basically what happens is the x axis changes with the bullseye it is 2.25 and with out it is 1.875. I needed my work piece to be 1.875 so the bullseys threw me off even though I had it checked to no out put and on a tool layer it still calculated it. I’m just asking if there is a better way to do the line up but I did put it inside the 1.875 parameter and worked for my lining up the 2 pieces.
Thanks for your help
If I understand you correctly, you had a shape you wanted to create, then you put a couple bullseyes outside the shape, selected everything and resized it. Of course your shape wouldn’t be the right size anymore, you resized everything. You need to set the size of your shape then add the bullseyes without resizing again. By putting bullseyes inside your shape you can resize it because they are within the constraints of the shape.
Maybe I still don’t understand what you did. Either way, you got your project finished.
I found a video by Material Placement 2 in Lightburn by Tony Paolillo that explains what I was talking about. It’s about the 38 min mark. If you have time you can check it out and if not that’s OK too since I figured it out. Either way Thanks for your help

Thanks for trying to help me understand what you’re doing. I watched the entire video and still don’t understand, but that’s OK. You were able to do what you needed to do.
One thing he does a lot that I don’t recommend is moving the laser by hand to position things. Once you move it by hand it no longer truly knows where it is. That’s not so bad with current position or user origin, but I tend to use absolute coords for most of my projects, so moving the laser head by hand is a big no no. With absolute coords there is no framing needed, although I do usually verify for my own sanity.
I appreciate all the help you are doing. The part where he has another thing on his work bed and it changes the center dot is what was happening when I had my bullseyes out side of my project so it changed my x coord. When i moved it inside then it didn’t affect centering my work piece. I don’t move it by hand. It’s a Roly MK2 20w.
Ahh, now I understand what you’re saying. I can see how that would affect things. That isn’t an issue with absolute coords, not that that is always the best choice, but it is what I use most.
That’s what I did. I used absolute cood and moved bulleye inside of design and it worked. Ive only been doing this for a little while so Im on the learning curve.
