Hey man, just wanted to let you know that you are one of my favorite channels and not much brings me the excitement that seeing you post another video does. I honestly believe you produce some of the most entertaining, educational videos on KZitem, and I really appreciate all the hard work you put in. I've never commented on a KZitem video in all my years of being on the site, but I reckon i had to make an exception today 😊

Congratulations! Like minds think alike. I posted a description of a solar CNC wood burner on the net over a decade ago. Mine suggested a method to slow down the feed rate when clouds roll by and stop if the burn power got too low. I had also suggested a solar panel to provide power for the machine so it would work off grid in an outdoor art display.

Neat-o, man! If you were wondering how narrow you could get the burn lines, here ya go... Even with a "perfect" convex lens, the diameter of the sun's image in the "hot spot" will be approximately equal to the lens focal length F divided by 107. However, heat spreading will end up giving you an even wider burn trail. (The math : the sun's angular width is approx 0.533 degrees. This is also the angular width of the hot spot image. So the ratio of the hot spot size to the focal length is equal to the tangent of 0.533 degrees, which is approx 1/107)

Hey I love your channel and this was a great build. I was kind of amazed that you manged to get optical sun tracking working without it being too erratic. Amazing. I'm a long time fan. I loved when you doubled down on the metal 3D printing and went Tig. That was quite a build. Anyway. My friend Lawrence and I built a solar plotter like this a while ago, and we did the sun tracking in software. If you have the x axis level, and just use a plumb stick to aim the entire rig at the sun, you can use current time + log/lat to apply incremental offsets to your gcode that compensate for the suns motion! (Won't work well for some 3 hour plot, but for something that only takes 40 mins to plot it works great, and is very simple/easy to set up.) Although you have to estimate gcode temporal position which can also get a bit off on longer plots. Sorry this kzitem.info/news/bejne/tYSty3mjraqlpaQ is not a good video, but we actually eventually got some very nice output out of that rig. Be warned that trying to go with an iris for variable line width is difficult. I built this iris kzitem.info/news/bejne/uH6G2Ht-e5mklHY , and did a bunch of tests but when the iris is too small there's just not enough heat to char wood, so the range of widths was fat->super fat, which wasn't that interesting. You might be able to reduce sfpm or have better optics to get very fine lines but just controlling the magnifying glass "size" with an iris works less well then you'd think, so be warned. Anyway. Keep up the good work! I'm ok with you posting more erraticly. Hell, I only post once or twice a year. lol.

@retrotechjournal
2 жыл бұрын
@@cranktowncity Yes, far more things should have motorized irises! I think part of the problem is that wood is just inherently a bit inconsistent so you can't be too close the "enough energy to cause charring" threshold or you get super inconsistent lines. I wrote an Illustrator g-code exporter for that project. I was hoping to then export line widths as z-axis positions to drive the iris, but never got a useful range of widths/results I was happy with. I can totally identify with all the "Oh god! I can't see my laptop screen in the noon day sun. I can't believe I'm using this laptop under a blanket in the full heat of the sun." wackiness that comes when operating a solar plotter. I can't wait to see what you do with it next!

Big ass fresnell lens from an old TV to gather a lot of light and a smaller convex lens to focus and make the beam a little more parallel again. Then use one of those window shutters to control how much light goes in and you got a pretty sick CNC burning setup.

*@Cranktown City* (eg: 13:12) You should add a little metal plate above the wood (an "idle plate"), so when it's done, the machine moves to that plate (eg: [0, 0]) and it can't start a fire. And if you add the plate a bit higher up, then the sun will not focus as much, so it will be even less dangerous then.

If you are moving forward with the project, you can add a servo-hand-flap-thing under the lens to close it shut after engraving is done to prevent further unwanted scorching( I think you may have already thought about it, if so just ignore me). You may also look into those big Fresnel lens for more powerful beam.
