    Thank you for the website, it is going to make a huge difference.
    If you work with acrylic, I would like to share with you something I have found challenging for last month or so.
    I want to cut rectangles of 4 mm thick acrylic. Not big ones, maximum dimension is 24 cm.
    BUT, I need to make holes on every edge, yes EDGE, of the piece.
    Holes are 2 mm diameter and 2 mm depth.
    And I have to engrave so many of them with high precision, therefor laser is the way to do it.
    If you can do it, or want to take a shot of doing it. Please let me know to share more details with you.
    Thanks.

    Keep in mind most calipers have a + and - resolution accuracy. The .08 could be + or - whatever the resolution your calipers can measure. So you will probably not get down to .01 anyways. Good video. Thanks.

    • @LetsMakeAThing
      @LetsMakeAThing  4 місяці тому

      Excellent point! The calipers I use have a +/-.02mm tolerance so as you said I won't ever get exactly .01. Which is fine for what I use the laser for.

    I was lazy, when I got my lazer (see what I did there?) and just cut a 20 x 20 mm square from 3 mm acrylic and measured the size with a caliper. They came out as 19.8 x 19.8 mm, so I calculated the Kerf as (20-19.8) / 2 = 0.1 mm. The "/ 2" is because the kerf is removed from the both opposing sides.

    • @LetsMakeAThing
      @LetsMakeAThing  3 місяці тому +1

      That's a good way to estimate. Only drawback is if the machine's x and y and calibrated that can add some slop and throw off the kerf number.

    Hello friend, first of all, thanks for sharing. I didn't understand what should be filled in this part:
    Label
    Material Note
    Label Power 30 % Output Power
    Label Speed 300 mm/s
    My laser is the xTOOL D1 Pro 10W and the manufacturer says the beam width of this laser is 0.08mm.
    P.S.: Could it be that by deduction, in my laser, the Kerf would be 0.04mm?

    Any chance you can run your kerf test again between .05 and .15? Chances are your kerf is not exactly .1 mm.

    Does this work only if your dot is square? Would it be a different test if dot size is rectangle?

    • @LetsMakeAThing
      @LetsMakeAThing  Місяць тому

      The size difference between square and rectangular dot sizes on diodes is only 1-2 hundredths of a millimeter. Such a small size discrepancy won't make a difference in the testing and kerf settings.

    Good afternoon! Here's a friend offering some important advice: use caution when dealing with MDF. Furthermore, it is worth extending this precaution to other materials, especially because regarding MDF, which is not widely discussed in Brazil, I had to seek information abroad. Although it is little talked about, what I discovered is worrying - there is evidence that MDF may be linked to cancer (due to the gases it produces when the cut is burned). But I couldn't find anything about the gases emitted when burning cardboard, could you say anything about that?
    Boa Tarde! Aqui está um amigo oferecendo um conselho importante: tenha cautela ao lidar com o MDF. Além disso, é válido estender essa precaução a outros materiais, especialmente porque sobre o MDF, que não é amplamente discutido no Brasil, precisei buscar informações no exterior. Embora seja pouco comentado, o que descobri é preocupante - há indícios de que o MDF pode estar relacionado ao câncer ( devido aos gases que ele produz durante a queima do corte). mais não consegui achar nada sobre os gases emitidos na queima do papelão saberia dizer alguma coisa sobre isso?

    Never actually cared of both these tests, nor needed, but it’s interesting.
    Wouldn’t it be better to run and set the calibration first, or it doesn’t matter?

    • @LetsMakeAThing
      @LetsMakeAThing  4 місяці тому

      If you don't set your kerf first it will throw off the calibration.

    • @LetsMakeAThing
      @LetsMakeAThing  4 місяці тому +1

      Yes it is common for the machine to cut under or over the size you request. That's the point of the second calibration I show in the video. You can use that to get your X and Y movements calibrated.

    Out of curiosity, wouldn't the kerf be the actual cut width as dictated by the DPI setting?

    • @henrywilliams1791
      @henrywilliams1791 4 місяці тому +1

      No, kerf is a per line parameter. DPI (some prefer LPI) determines the spacing between adjacent lines.

    • @LetsMakeAThing
      @LetsMakeAThing  4 місяці тому

      As henrywilliams said, DPI is the spacing between lines. Since a cut is only a single line DPI doesn't apply.

    • @Sven2157
      @Sven2157 4 місяці тому

      @@LetsMakeAThing When you adjust DPI, you are essentially making the laser beam, the cutting width, no? So once that is set, you know the cut width, just like with a saw blade. Adjusting kerf, seems to be the EXACT same thing as cutting to one side of the line, to adjust for laser (saw blade) width. Right?
      EDIT - My point is, that you don't need to waste material when you can just adjust for the width of the laser beam, by setting KERF to the DPI/Line Interval. Am I missing something?

      The kerf of the laser beam is specific to the laser itself and you have to test for it. Each diode laser has it's own personality due to manufacturing and quality control processes. So the only way to know the kerf of your laser is to test it by using material and running a test like the one in the video.
      You can't adjust the width of the laser beam via software as it's a physical constant of the laser. Just like I can't adjust the kerf of my table saw blade. DPI changes how close each laser pass is to the previous when doing a fill. If you look in Lightburn there is no DPI or lines per inch setting when a layer is set to line. If you change that layer to fill then lines per inch will show up. This setting changes how close together the laser lines will be.
