It was a fun project to put together and lightburn really helped with getting the acrylic cut accurately. I used a .155 kerf offset to maintain dimensional accuracy inside lightburn but that will depend on your own laser settings. The making of video can be seen at https://youtu.be/q6MGKOqCm40
If I was going to make the entire project with a laser cutter I would recommend dropping the 3/4 oak in favor of multiple pieces of 1/4" panel bonded together as being cut.
This is a cool project - I like things that are simple, but functional and pretty.
One minor detail I noticed in the video - when you created the cuts, you used two different settings, one for the outer edge and one for the inner, but thatâs not usually necessary. LightBurn handles kerf using the same offset engine as the âOffsetâ tool, and it automatically determines inside / outside edges and offsets accordingly:
The object being offset is shown dotted, using outward kerf:
Notice that the new vectors are adjusted in the appropriate direction, and this means that you donât have to manually remember to do inside / outside sorting. (I noticed you cut the outside shape first, which occasionally results in the part dropping and missing or misaligning the inside cut).
Not in any way intended as a critique - I think most people just donât know the system is smart enough to do this for you. (it can fail if you have âsurface markâ vectors in between your shapes)
Thanks @LightBurn! The information about the offset definitely will simplify some of my future cuts. I love the software, the more I keep using lightburn the more gems I keep uncovering.
I actually did cut the initial pieces inside then out, but I had a camera issue so reshot and somehow flipped my cuts. But yeah I think the second piece actually was slightly deformed because of the order of operations.
Hello! It seems to me that the author has a super power, I just donât imagine how it is possible to do it! I just started to learn this program. Before that, I used only Paint) I would watch your lessons on YouTube or another source. If there is such a share a link. Good luck!
