    My biggest thing was learning to do ONE SINGLE SCAN per squre, not crosshatch. I would get VIBRANT bright solid green..yellow..etc in stainless. But the minute I tried to put it onto something else, a big design, it didn't copy. Learned t was due to the heat not being the same as a 3x3mm box doing 2 scans. Ever since then, I just do a single scan, no crosshatch, and the color repeats dead-nuts accurate on any size decal. Love how vibrant/bright the colors can be when you get them tuned!

    • @MakrTheory
      @MakrTheory  Рік тому +3

      Because the test doesn’t identify cross hatch vs. single pass, I try to run the test in single pass to avoid confusion. Plus nothing worse than seeing a vibrant color and then see the cross hatch wipe it out.

    Since the focus seems to play such an important role, do you know if the material thickness plays a role? Would it mess with the focus ever so slightly, resulting in different colors with the same settings?

    • @MakrTheory
      @MakrTheory  11 місяців тому

      When focus was properly set, thickness did not appear to make any difference on the material test grids. Perhaps that could change when marking a large area and a thin material were to overheat or warp. But that would be an issue of going out of focus.

  • @ulrichlumb7572
    @ulrichlumb7572 Рік тому +2

    Great video with a thorough approach. Concerning the out of focus colors: an easy way to a controlled defocus testing is to set the target at a slight angle so that each hatching field has a a slightly different height and a controlled defocus. I have sometimes used this approach with a different laser. Keep up the good work.

      You can start with what I ran on one of my initial tests that got color, but I would drop the power to 30% of what I use in the video. Lens plays a factor as well. If you are using a lens smaller than 175x175 (F254), you will likely need to drop power a little more.

    can the stainless steel rust after engraving on it? and I'm talking about black engraving and color (MOPA)

    • @MakrTheory
      @MakrTheory  Рік тому +1

      Yes, it can. Stainless is corrosion resistant because of an invisible (to the naked eye) layer of Chromium Oxide. This is the result of a chemical reaction between oxygen in the air and chromium in the metal. I usually apply a light coat of Bar Keepers friend on the mark and let it set for 3-5 minutes to try an build up the oxide layer. I plan to do a video testing different methods of post treatment to protect the marks on stainless.

      Could be a setting not turned on, or you have a fixed pulse width MOPA. If you have an “M” series JPT, then you will need to go into the laser settings and check the box to turn on QPulse. If you have an “LPE” series, then it will be locked at 200ns no matter what you type in.

    Excellent videos,
    I’m looking to buy a mopa fiber laser to mark metal, mostly copper, brass. My question for you is what gives the color, is it a frequency of the laser type thing as it seems by watching you video or is there a physical color dye that is somehow added to give color? I’ve searched for information on this and am getting conflicting answers to the question. Thanks

    • @MakrTheory
      @MakrTheory  11 місяців тому +1

      Thank you. Marking copper and brass take a lot of energy, so if you plan to mark large pieces or quantities of pieces more than just hobby, I would definitely look to 60w or more.
      For the color marking, there are no dyes. I have seen conflicting answers as well. For the most visible and vibrant colors, I believe the answer is a mix of the microscopic grooves left in the material distorting the light and the heat temper of the metal. If it was only the grooves, we should be able to get the same colors on aluminum or copper alloys as well, but I have never seen them on those materials.

    How durable are the markings? I suppose the lighter colored ones are prone to fade, discoloration, rusting(?) when used outside. (in direct sunshine, rain, frost, etc) I would bet on the blackest setting when used outside, how durable is that?

      This is something I have been monitoring. Some of the samples had been made months before filming and sat in my non-climate controlled garage during that time. I live in a very dry area, so higher humidity areas may see different results. I plan to follow up with further testing, exposing the marks to corrosive environments and find solutions to preserve the marks if necessary.

I do not yet because my laser has a low max pulse energy and I had mostly larger lenses, but I have experimented with other machines and I would start by increasing frequency and speed by the same multiplier. It will take make more passes. Low frequency with high power tends to leave micro craters and splash up material.

      @MakrTheory  11 місяців тому

      You can get a shimmery “white” and black/dark gray. Colors are limited to iron alloys (ferrous metals) and some exotic materials like titanium. Good way to verify is if you can heat the metal to near melting and see a rainbow effect after it cools, you can laser mark colors.
      It doesn’t take a lot of power to make the color marks on stainless. 20w is adequate, but if you also plan to do engravings on larger items, you will want more power.

      You are welcome! You will want to make sure your laser is an adjustable pulse width model. If it is a JPT and has “M1”, “M6”, “M7”, or “M8” in the model number, you will have the ability to control pulse width. There are other laser manufacturers that offer adjustable pulse MOPA laser, but JPT is the most common.
      To enable the controls, you will need to go to the device settings in LightBurn (the icon with the wrench and screwdriver) and and toggle the enable QPulse switch in the middle of the window.

    Its me again, a proud new owner of a JPT MOPA 60W. Already tried some colors on stainless steel, look great, interesting. But what I could use more in my business would be the blacker blacks, and whiter whites (not shiny, but matte white viewed from all angles) both an stainless steel and aluminum. Can you give me a clue what specific settings there are (if any) a MOPA is capable of marking deeper blacks than a plain Q-switched laser?

    • @MakrTheory
      @MakrTheory  Рік тому +1

      Congratulations! I have not experimented with white, but black marks are typically pretty slow. The advantage to MOPA for any color marking is being able to use a standard focus distance, instead of being out of focus. Out of focus required the material surface be very flat and uniform for a consistent mark.
      Your source model and your lens size play a big part in getting the right settings. I am currently working on a calculator that will help translate settings more accurately. If you can provide those, I can give you a good starting point.

      I need the darkest black marking possible on stainless steel and aluminum ( I know it works best on anodized, and only grey is possible on pure alu, would be also great to improve that) .
      Already tried to do some tests with multiple passes on steel, especially when marking QR codes as part of machine data plates, a higher contrast makes the QR code better readable. It is though important that the marking looks dark from any angle, I already managed some tests that look silverish shiny from one angle, and almost black from another angle. Interesting but not what I can sell.
      What I also tried is to clear the surface with a 'clearing', white run first, a rectangle behind the QR code and then mark black on it, but maybe this approach is too much of hassle though and does not give a better result at all.

What I learned when I looked at it at an angle during the marking right after the first pass but before the second, it was then showing different darkness depending on the angle a looked at it. But the second pass made it right, now it looks the same dark at all angles. 👍
      I think did not pay attention to turn on multiple passes / cross hatch at my earlier testing. and also those five setting make a lot of combinations we have to try out. Thanks a lot. One thing I will keep trying to refine later, if there is a setting that marks faster with the same results would be even better.

      3) Double check layer settings and look for unwanted subroutines on the layer
      4) Restart the laser and the computer and repeat step 2.
      5) If results are still black, attempt another established setting from your library and see if that gets the expected result.

    • @MakrTheory
      @MakrTheory  Рік тому +2

      Unless you get a high end lab grade lens varies slightly, so a focus stick is something you make or order to size after you have found the focus distance for your lens.
      I have been meaning to make a video on finding focus, but for now, a real quick way the find the focus is put a piece of of scrap steel or stainless steel on your laser. Draw a square an easily measured size (1” or 30mm) and trace the shape. Adjust the height until the trace measure the same as on your your software. That will be close, enough to start.
      To increase accuracy, raise the lens another 20mm and use a high power setting and use and offset fill on the square. Check the “Continuous” mark setting and run the mark. Slowly lower the lens. You should see the burn intensity increase until you get to the focal point, and then they will start getting weaker. You will want to go back up until you get the strong sparks again. That will be your focus distance.
      You can either order a focus stick to size, or Patrick @LSEngraving sells an adjustable one that you can make to the length you need and then glue or bolt it in place.
      I’ll make it a priority to get a formal video up soon.

    Hello from Germany,
    Mate - you did a great job! I’m a beginner on this laser stuff. I was reading, watching UA-cam videos and many more. I think I will order a 50w gweike MOPA laser soon. For the beginning I just want to mark / engrave in black color on stainless steel plates. Do you have any good experience to share with me? What are the best parameters?
    Thanks for your support!

    • @MakrTheory
      @MakrTheory  11 днів тому

      Hello. Thank you. If you are wanting a MOPA with adjustable pulse width, like mine, you will need to make sure the source model number has an “M” in it. Typically they are 20w, 30w, 60w, 80w, or higher. The JPT 50w is a fixed pulse width of 200ns. Model number will have “LP-E” in it. This will work for marking black, but other colors will be more difficult. If the listing you are looking at doesn’t state what laser source it is using, make sure to ask before you purchase. If they don’t want to tell you or can’t, do not buy from them. Find someone that is knowledgeable and transparent about their product.
      I found better results for colors, including black, using a larger lens. This will reduce your ability to deep etch, so I always recommend getting couple lenses for your machine. 110x110 is good etching and general purpose. I find 200x200 or larger is better for color marking, but will not etch very well. You will have to experiment with your specific setup to find the best parameters.
      I hope that helps.

    I’ve been looking for this Mopa testing and information thank you! I have a 30W JPT MOPA too and most of my need is to engrave deep black on silver anodized aluminum. I’ve struggled with settings and consistent results. I seem to get the darkest at a Q pulse of 2 at 460khz. But even then the viewing angle is not wide (lighter as angled) and lighter than hoped. The range of options are endless, just recently considered ‘out of focus’. I would be elated if you made a video with this material.

      You are welcome! Glad you enjoyed it. Anodized aluminum is on my list of materials to do more experiments with. Make sure to subscribe with notifications turned on so you don’t miss it.
      Out of focus can increase your spot size and disperse the energy over a larger area. If you do try this, make sure you lower the focus below the material to help reduce chances of reflecting back into the lens. I personally prefer switching to a larger lens rather than out of focus because the depth of focus provides more forgiveness on uneven surfaces.

Look for the “F” number on your lens (ie a 175x175 is F254) Set your lens height the F number +100mm) For your 100w, I would start with 600mm/s, 80%, 70khz, 650ns.

      Being able to select an existing library setting for the test seems like a reasonable feature. I will make a feature request for it with LightBurn and see if they can add it.

      Not really. Black and white are possible on anodized aluminum. I have seen some people get an ugly grey color from raw aluminum, but looks more like a grainy soot than an actual color. To get a range of colors, there needs to be iron or chromium in the metal.

    • @MakrTheory
      @MakrTheory  Рік тому +1

      There are a couple ways, the colors with more shimmer to them are a microscopic surface distortion that bends the light to make our eyes perceive a color. The more solid colors are a heating of the material to just the right temperature to produce a specific color, similar to like you could do with a flame or TIG welder.

    • @MakrTheory
      @MakrTheory  7 місяців тому

      @MasterTheNEC there are some variables that will change with every setup. The lenses typically used on these lasers are “economy” grade and have a wide range of variability in the focus and work area. This will change your spot size and the ability to mark materials. I try to do everything as a single pass, no crosshatch. I would select bidirectional or unidirectional and just keep that setting fixed through the tests.

    • @MakrTheory
      @MakrTheory  7 місяців тому

      @MasterTheNEC I felt that way initially too because the MOPA adds another variable to figure out. Honestly the MOPA is the better machine and can do way more, once you get used to it. When you get a color you like, do a new grid narrowing in on those same variables. If you are already really tight on one of those variables, you can lock them in and start using another variable on the grid to see if that helps vibrancy. Just take it in small changes.
