When I was offered the opportunity to beta test an upcoming robotic arm from Tormach, I knew exactly what I wanted to do with it. CNC chainsaws baybeeeeee. Aside from being fundamentally awesome, it is a very interesting software problem. Since I didn't have to build the arm I was able to focus the project and the video on the software challenges of making something like this work. Thank goodness I didn't have to build the arm because the software almost killed me. I can imagine all kinds of next steps for this creation like machining textures with the chainsaw or cutting topiaries. I hope you like it!

I'm currently working on printing a CNC milling machine though I don't know what I'll use it for lol. Any direction would be appreciated. Love all your stuff btw, you're a real inspiration!

  • As someone who uses a chainsaw on a daily basis, I must comment, that it's clear that your trying to push a dull butter knife through a piece of wood. In other words, it's dull. The second you put on a new, or freshly sharpened chain, you will see a world of difference. If you don't know how to sharpen it, you should probably take it to a shop, where they generally charge $9 to $12 per chain. Also, in on of the shots, the chain was loose. It must have the proper tension, and be Sharp.

  • The funny thing is that you didn't even bother to ask someone who uses chainsaws whether or not a pole saw could cut a log. Obviously you figured out the answer, it can't! A pole saw is meant for small branches. Heck, it probably even says that in the manual, which you always brag about not reading. :)

  • So... honest question here... Why didn't you iterate off of the pumpkin carving setup for this machine? I know it's not as cool as chainsaws - but you'd have the potential for some amazing functional 3d CNC work that could push the community forward (especially if you're willing to open-source your work) and also provide you with some very unique patents (which you could use to ensure that the community doesn't get bulldozed by some company that wants to own sole rights to this kind of tech.) I love your content, and expanding it beyond casual youtube shenanigans to create/evolve the industry would be mind-blowing.

  • Not an engineer, but am a chainsaw wielder. I think the problem you were having with the wood is a combination of not having the proper chain/bar combo for carving, the chain not being properly sharpened, and not having enough RPMs to cut through it. Solution: Better bar/chain, a good file, and a stronger motor pulling at 12k RPMs.

  • Idk maybe I am kinda dumb here but for the coding why would you not start with the points closest to the center and a 360°° Angle (aka twice the same cut) then instead of testing every angle you simply do a half aproximation so it checks 180° next then either 90° or 270° depending on if that cut goes into material or not and so on for about 5 or 10 steps (I doubt a chainsaw would be any more accurate than that. then repeat that for all relevant points until your initial structure. (aka any point that concave with a reasonable precision so points can for example be no closer than 5 cm together which would be about the accuracy I expect for this tool.) Once all those have been computed you simply do the same but in a single cut for all convex points. After that you would have the robot execute the found steps in reverse order. This should result in a reasonably fast program while allowing relative good precision. The only downside to this solution is that holes would be impossible to calculate so for example the dog legs would need to be connected to the body. I have thought of another solution that technically would allow holes in structures however it would only allow low polygon count inputs.

  • Several items that will help out a ton. An oiler for your chain. A chain that is designed for feller/buncher systems. These have more teeth per foot and are more aggressive in cutting. No kickback, your bot has strength in its joints to prevent any kickback from breaking things. The bar itself needs to be twice a strong as a normal consumer level bar. A bar designed for feller, buncher, firewood processor system is higher recommended. Look up Pacific Trail Manufacturing Systems for a decent selection. Make sure it'll fit your current setup, or you'll be cutting a new mount.

  • Hey. I just want to say that you’re the reason I started exploring more fabrication and tech builds, why I’m typing this in my first ever apple product (iPad Air 4 256gb with gen2 pencil! You made it look so amazing I had to get one!) and why I’m ordering a glowforge soon! (If you do a sponsorship, I’ll happily use your link or whatever.) You still make most of this look like wizardry, but you’ve boosted my excitement for nonsense builds a million fold! I’ve been doing small scale builds, crafting, leather and basic 3D printing, but I plan to get into much more engineering. I have cancer and started crafting as a necessity to help support myself and my mother, but you’ve helped me see how ridiculous and fun it can be. Thank you!

  • There is a relatively easy way how to calculate the gradient ascent, even if you have multiple maximum points. Start scanning a linear line, let's say along the length of the object starting near the edge, and record the heights. repeat that with a rough distance, let's say 6-7 mm scanning another line parallel to the first one and recording the heights again. Do it until the object is roughly scanned, which should be a couple of lines, and should happen quickly. Repeat the same on the perpendicular direction along the width of the object, again a couple of parallel lines. Once finished, you have obtained a rough heights matrix. Let's assume that you've discovered that this height matrix includes 3 maxima (maximum points) All you have to do now is get the height sensor to do the standard algorithm of gradient ascent you used before and start with the nearest point next to each maxima and repeat that 3 times (once for each maxima). Once done, you compare the 3 heights you've got and take the highest one, which is your point. In order to avoid mistakes, when deciding on how many maximum points the algorithm should check after the initial scan, just make a condition that the difference between maximum heights should be higher or equal to the distance between the linear lines you measured initially. That way, you reduce the to-be-measured points into minimum number possible. Good Luck Lemogan
