    Thanks a lot Rich, your videos are utterly helpful for anyone who has to do with lasers and this issue with Lightburn camera drove me nuts for the past few months, I will try your recommendations out... I am only curious in regard of positioning these wood pieces, I have a Sculpfun s30 Ultra with a bed size of 600x600 mm, I would then place the wood pieces exactly in the corners of my work area and then laser the circles? Because in Lightburn ver 1.7.03 there is a somewhat improved (different) way of aligning lens and camera (with AprilTags additional to the Circles pattern and what not) and there is an option in the Camera Alignment dialog box that allows expanding the sample image (circles and numbers) that is going to be engraved on the wooden plates, which allows the user to scale automatically (in my case 273%) to fit the Workarea. Thanks in advance and have a nice day!

    • @TheLouisianaHobbyGuy
      @TheLouisianaHobbyGuy  6 місяців тому +1

      It's done by thickness, not material. I stack these 2mm wood squares to the thickness I need: amzn.to/4bCDxlp
      You could also stack craft paper under the wood to bring it to the thickness you need.

    Great video as always. I have done both tests in Lightburn get my camera to work correctly and still having issues. Will try to make this short. I have a WeCreat Vista 10w. When using the Makeit software, I don't have to frame anything, I know where I put text or a design, that is where my laser is going to burn. In Lightburn, even after calibrating, I have to put my design about a 1/2 an inch to the left and about a 1/4th of an inch higher then where I want it to start. I have had to do it so much that I have it down pretty good but I would really like it to start where it should. Any suggestions would be awesome!

  • @NealsBumblebeeCrafts
    @NealsBumblebeeCrafts 6 місяців тому +1

    It took me a while to realize this need to create settings for each thickness. The LB doesn't really make the purpose of "material thickness" in the setup window clear.
    My *current* issue is that I'll run an alignment, then burn boxes in each corner and the top boxes will be spot on but the bottom could be off 1/8 - 1/4". I can't adjust the x/y to correct the "astigmatism" without throwing off the top boxes.

  • @user-vj5kb4gr6v
    @user-vj5kb4gr6v 5 місяців тому +1

    Thanks for the video. I watched it all the way to the end, but still have a few questions.
    1) Your explanation about the material thickness does not make sense to me because whether the material is 1mm thick of 1 foot thick, the surface that is being engraved upon is still the exact same distance form the laser head (and camera) so what is the difference how much material is beneath that surface? You related it to moving a DSLR further away from a subject and "of course" it is out of focus, but that really is not the case here because if I put on a material that is 1cm thicker, then I drop the bed 1cm so the distance from the surface being focused on and the lense has not changed at all.
    2) Brilliant to burn the pattern much larger, as you have, but you skipped over the part about how you determined the size. I assume that you just put the 2 blocks at the extreme corners of engraveable areas and then just placed the other two so they form a perfect square with the initial two and then center the 5th one, is that right? Obviously, you would have to measure exactly how big that square is in order to scale the burn area.
    3) Lastly, I have set my camera up with the dot method which was a nightmare of an experience and I am not even sure if it is accurate (though I got it to complete so allegedly it is). It sounds like you are saying I did not have to do that at all and could have just picked the lens angle from the dropdown and skipped that whole step, is that right? With my camera it does list it so would I be better to use that preset or leave it alone since I already did the dot method?
    Thanks again for everything you do. Much appreciated!

    • @TheLouisianaHobbyGuy
      @TheLouisianaHobbyGuy  5 місяців тому

      Okay, so:
      1) The distance from the *camera* to the material changes since the honeycomb or waste board are both in fixed positions.
      2) I just increased the size of the pattern by a % and looked at the preview.
      3) Yes, better to use the preset IMO.

    • @user-vj5kb4gr6v
      @user-vj5kb4gr6v 5 місяців тому +1

      I much appreciate your reply, but the first point still doesn’t make sense to me. You said that the honeycomb or waste board is in a fixed position, but it isn’t in a fixed position. It moves up and down, so if the material is thicker, then the honeycomb is lower, so the surface is still in the same place. I’m not familiar with other lasers so, based on what you are saying, I’m wondering if with other ones that honeycomb does not move. If that is the case, then what you’re saying makes perfect sense to me.

    • @TheLouisianaHobbyGuy
      @TheLouisianaHobbyGuy  5 місяців тому

      Yeah, so on a Co2, you're right, the honeycomb does in fact move and this doesn't apply.
