I have been trying for 2 days to get a KERF setting for my new 40W laser - trying all the techniques on so many websites only to get totally frustrated because nothing changed. Your video made so much sense and within a few setting attempts, I was able to get a solid KERF for the 3 mm baltic birch I am using and a solid KERF for some Cast Acrylic I was trying out. Thank you so much for your videos - they are priceless!

Dividing the found kerf by two is because the beam is following the given cut line, where half the kerf is inside your work piece and the other half outside. So the found number is the real kerf's diameter. Manufacturers claim values of 0.05 to 0.08mm, but is only valid by shalow engraving and perfect focus

@@TheLouisianaHobbyGuy I'm getting very promising results. Been practicing on clear plastic spoons. 5w laser. So far the best looking one was 3 cuts. First: 2200 mm/min 10% Fill in X direction. Second: 2500 mm/min 5% Fill in Y direction. Third: 2200 mm/min 10% Line. Takes off airbrushed grey Duplicolor Vinyl and fabric paint. Leaves white of the same type of paint. Looks grey and white from the top for daytime visibility but lets light through the artwork when held up to the light. If you look at the back of the spoon not up to light it looks totally white with no graphic. Exactly what I need for my RGBW to show through. There is a short video of a button I made during testing on my uploads if you're curious. I hand scraped the design with a poker because I was anxious to see a preview so that looks bad. I don't have any videos of the laser results up yet, but they will be coming. I have a friend that does sourcing for an airplane manufacturer and she said the spoons look better than one of the vendors she's been dealing with lately so that's a good sign. I set up an old 720p camera too and that is certainly a game changer for efficiency and accuracy. When I first got it I was messing up the focus at first and didn't think it would accomplish what I needed because the beam was too big. Then I realized I was putting the focus spacer in the wrong spot. I put it in the right spot and saw the correct size of the beam. That is when I realized it may be capable after all. Then I found your videos while trying to add limit switches which was more confusing than it should have been. The board in mine is a Makerbase MKS LTS V1.1 and the manufacturer is using the Z and Y limit switch sockets for an accelerometer. I had to flash the firmware and use the probe socket for the Y limit switch. I had to figure that out without help from the manufacturer due to weekend and slow response time. Then the instruction video they sent me had a different board so that was of no help.

This is good to use if you need an internal piece to suspend and twist inside of another.

No, not quite. You have to account for the kerf.

Didn't realize that different width materials affected kerf offset as I had a wtf moment this morning. Lesson learned - different thicknesses mean different offsets. But I had another observation I wanted to ask you. Does power/speed affect offsets as well? In other words, if you are cutting with excessive power/speed you will "vaporize" more material thus, affecting the kerf offset, right? So I'm thinking before performing the kerf offset grid test for a particular material it would be best to zero in on the optimum power/speed first. Thoughts? Thanks, as always.

@TheLouisianaHobbyGuy

Жыл бұрын

Yes, of course! You can just offset it.

So, the fact you cut the inside in black just means you can make a second earring with a black interior and yellow exterior -- then it looks like you did it on purpose. 😉 One question, you applied kerf to only one part, seems like by applying the kerf to both parts (1/2 the amount to one, 1/2 the amount to the other), you will get a better fit since in reality, both pieces are affected by the kerf equally and the real kerf width is 1/2 the total you applied to the insert pieces. The piece with the inner cut should cut to the outside of the line by the kerf width, the pieces you are cutting with outside cuts should cut to the outside of those lines by the kerf width so that both pieces are being cut to the original lines. Makes total sense that kerf changes with changes in conditions and material. The materials we are using, especially the woods, were never intended to be worked down to 1/1000's of an inch. Wood moves with humidity changes, more in the cross-grain direction than along the grain. When doing furniture work, one always allows for wood movement in the finished piece so it doesn't break the final piece apart during seasonal changes in the environment in which the piece is placed. That movement is significantly more than a few thousandths; one usually allows on the order of 1/32 or more for movement cross-grain. It's cool that we can do this kind of precision with lasers, but your advice that testing is always needed makes total sense. Good news is that manufactured materials like plywood are more stable because they are manufactured with the grain between layers being laid perpendicular to one another. They are still going to move and the adhesive properties between batches are likely to change.
