      Good luck and let me know, if you were successful. :-) My tipp: when doing something with your Snapmaker for the very first time, always do a bounding box run and have one hand on the ergency stop button. I own the Snapmaker 2.0 which does not come with a stop button by default and I had to learn some lessons the hard way. ;-)

    What an excellent idea!! What about adjusting position to get it registered? Has it some trick, like that point I see on a tape at the top of the glass? how can you control you don't move the rotary tool when positioning the glass, what do you align it with? Do you engrave the white engraving on top of the back engraving or in your artwork you leave that out of the second engraving?

    • @harvey7113
      @harvey7113  7 місяців тому

      Hey Fancylooks. The realignment question has been asked before, so just let me copy the answer from there:
      Realigning the object is a little bit tricky. That's why it isn't on the video. My apologies. I use a label printer to print out a simple plus-sign and stick it on the outside top of the glass, as you can see in the video. Before starting the engraving, I switch on the laser and position it to the center of the plus sign. Tracking the laser with a camera is difficult due to overexposure. So I put on the laser safety goggles, open the enclosure and adjust the y and b axis manually using the controller until the laser dot is exactly in the middle of cross. Using a flashlight is helpful, because the safety goggles are quite dark. The position is perfect when the laser dot disappears or becomes very dark - that's when it hits the center of the cross. Then I set the work origin for y and b axis. I can't recall the exact order, but it is crucial not to interfere with the z axis calibration. Of course, you have to do this for both layers. The sticker is very sticky and water resistent, so it will stay until the very end.

      If I would make one or two glasses again, I wouldn‘t change much. But two things were a bit exhausting and I would probably optimize that for batch production: 1. Applying the coatings with the tiny air brush took really some time. I would try something different, like an „airless sprayer“. 2. Aligning the laser each time was tricky. Maybe align the laser once and attach a mechanical pointer to the rotary for alignment of just the rotation. Does that make sense?

    Great video, just a quick question, as a quick google search did not come back with the answer. Does the paint need to be titanium oxide when using white paint to get the darker/black colour in the etching? I ask as I have been using basic tempera black paint for coating the glass, and then etching with it. The black paint i have been using gives me the white frosted looking, however I have not tried using a white tempera paint to see if it will yield a different result.

    • @harvey7113
      @harvey7113  10 місяців тому +1

      Hey Jordan, thank you for your comment and question.
      Short answer: Yes, it has to be Titanium Dioxide.
      Long answer: For the white frosting, the compound of the paint is rather irrelevant. It is just to absorb the blue laser beam and convert it to small spot of heat, which will result in microfractures in the smooth glass surface. The paint will vaporize completely and leave the injured, frosty glass surface. The darker the color is, the easier the beam can be absorbed. That is why I use black paint. But it should work with any color, even white, as long as it does not contain any TiO2. If you have a CO2 laser, you can event omit the paint for this phase. The CO2 laser emits infrared light, which will be absorbed by glass.
      But if you use TiO2 particles or a paint with a high level of TiO2, the TiO2 particles will not vaporize but "melt" to the glass surface. At the same time, the particles suffer from the same microfractures (or similar transformation) as the glass, but here the particles become more absorbant and thus appear black.
      Disclaimer: I am not a chemist, so maybe my explanation is not 100% correct.

      I actually 3D printed this centring device myself. It's not rubber, it's hard plastic (PLA). You can't see it in the video, but the surface is not straight, it has steps in it. It's just stacked cylinders of 1mm height, each cylinder 1mm smaller in diameter than the one below. You have to fiddle with the jig a bit until the right diameter clicks in, and then the glass is perfectly aligned with the axis of rotation. I hope this makes sense.

    I have an idea for your positioning. I haven’t used my rotary yet so not sure what parts “move” but on a non moving part of the rotary make a line, then on the “Plug” make a line, then on any item you need exact alignment, make a line (Like you did with the +) on a piece of tape and put it on the item in the middle of design area (Also like you did) now align all three lines. Each time you go back to that exact area just realign all three lines. You wouldn’t have to make a mark on the plug if the line on the machine itself was close enough to be able to accurately align, but I figured if you have a line closer to the cup it would be easier to align. If you’re bored, maybe try it. Where is the design for the plug? I finally got the “test” laser project completed and need to get back down there and do some more. I’m just learning and the whole “Settings” and using Luban confuses me. The test design (rulers) was a hassle and took a lot of time/frustration as it doesn’t tell you that it shows the design up in the right corner, not centered

      Hi, Jake. Though it is surely not necessary, I find it quite helpful.I do not want any paint on the sticker with the plus-sign, because I need that to align the origin. I do not want any paint on the lower part of the glass, because that would soil the chuck. But I do want an even and thin coating without any gaps where the laser will work. The masking helps me concentrate on that area. Also, I do not use any binder with the TiO2 pigments. So, whenever I touch the white coating, I get pigments on my fingers resulting in white fingerprints everywhere. ;-) That's why I like to have a clearly delineated area, so I know where I can or cannot touch the glass.

      @harvey7113  Рік тому +4

      Hey, thank you for pointing out that TiO2 is (at least) questionable. After your comment, I did some research and as far as I get it, the substance is prohibited in food and pharmaceuticals, but not in paints. But better safe than sorry, so please either use a mask and gloves when handling it or - as you suggested - replace it. Frankly, I haven't checked any alternative substances myself, but there is a very intersting acticle on the Snapmaker support forum: support.snapmaker.com/hc/en-us/articles/9589024708759-Laser-on-Ceramics-How-to-Make-It-Not-Only-Black-on-White. That one is about ceramic tiles, but as most ceramic tiles have a glass surface, it should also apply to pure glass. Please let me know, if you find a suitable replacement and I will mention it in the video description.
      The "cork" is printed on the Snapmaker with regular PLA. It is not just conic, but has steps in it, like a step drill. So you just have to try a bit until the best diameter snaps it. It does not have to be perfect, some tolerances are okay.

    How well does this medium hold up compared to enamel paint? Has anyone tried this on a co2 laser?

    • @harvey7113
      @harvey7113  5 місяців тому +1

      I don't have any experience with emerald paint on glass, but I think the method shown in this video will give a stronger result. In particular, the white frosty effect is not paint applied to the surface, but the result of small cracks in the structure of the glass. The black paint is only there to absorb the energy of the diode laser, otherwise the beam would go straight through. If you use a CO2 laser, I don't think you need the black coating at all because the longer wavelength is well absorbed by the glass. The stickiness of the black effect, on the other hand, depends on a perfectly thin layer of titanium dioxide. I am not a chemist and cannot explain exactly what happens here, but I imagine that the heated TiO2 changes its structure and thus its reflectivity (is it calcination?) and that it "melts" onto the glass surface. TiO2 is also very hard and durable. I claim the result is at least dishwasher-proof. Heating the pigments to the melting point should also be possible with a CO2 laser, perhaps even better than with a diode laser.

      It is definitely dishwasher-safe. The white layer actially is no color at all, but a result of a "destroyed", blunt glass surface, so no way that this will go away by washing. The black layer is titanium dioxide somehow "melted" to the glass surface, so very hard and very sticky. Important: always start with the titanium dioxide layer, so that it will find a smooth glass surface to which it can stick.

      Hi. What laser do you have in mind?
      I am pretty confident, that this method will work with any diode laser. Depending on the power you would have to go faster or slower. If in doubt, go slower - you cannot "overburn" it. If you have a CO2 laser in mind, then I must say I do not have any experience on that, but I guess this method should also work as is, as long as you use proper settings. But with a CO2 laser, I guess you would not need the black (Gouache) coating, because this kind of laser can engrave glass directly because of the much longer wavelength.
      If you are speaking about machines, any laser machine with a rotary module should suffice. Of course you would need a software supporting the rotary. There are also some machines/softwares out there that are not limited to cylindric glasses.
