Please consider supporting these projects through my patreon:
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!

    Why don't you do something worthwhile with your time, equipment and clearly huge disposable income? There are millions of starving people around the world you could help with your talents and engineering ability. Making USplan videos contributes pretty much zero to humanity and just burns up energy in servers around the world. Sorry but all this effort to create a (bad) facsimile of a dog out of foam sheets is an insult to the world. I know there are worse offenders but do you really need to join them for the sake of 2.55 million subscribers? Edit; yes, I'm disappointed with myself for using my computer (and the electrical power) to watch this whilst locked down. Pathetic.

    Speaking as an artist , who has spent the time and made the sacrifices to learn a real skill. By hand and by ones own ability. Every time one of you types comes up with a device to automate art. Is a loss to something special in the world. .. the more that is done for you , the less you can do for yourself. Cheap art made by machines, has no soul , no love . Frankly speaking, I'm not impressed . Keep on this track , down the road people like you will be helpless unless you have machines to do the work for you. "And dont think they will always be around" No matter that you have the technical skill to create this device, art should be left to artists , your way buys into capitalism. This is disgusting. You could do better for the world with your abilities, to create something that truly can help the world . This is just theft from people who are becoming more rare in such an over automated ready made world . . You could really do better with what you can do. This isn't helping anyone but yourself. Greedy .

    Man you used the wrong saw… you can do a better job with an angle grinder with a chainsaw blade, you might not be able to go as deep but would help in completing the look plus I think your saw speed might be to slow also with the skate board motor, there's a circular saw blade called Prazi which might be better. Blade speed plays a lot in how much you cut, and it looked like you saw blade was to loose.

    I wonder if your saw chain couldn't either be modified to cut at the tip or a chain couldn't be bought designed to do just that? I could ask my logger neighbor with 35 years of dealing with saws, chains and bars. He's my go to guy to tune up my Poulan and put a quicker cutting edge on even a new chain. Perhaps checking with one of the guys that do the chainsaw carving. I've seen them carving and know they use the tip to cut... a lot. :)

  • Michelle Lewis
    Michelle Lewis9 hours ago

    you're going about it all wrong......chainsaws require sensitivity of touch and intimate understanding of how the tool cuts, so that which moves the tool needs to have that knowledge and sensory feedback from the cut. You also have to account for the variability of the material properties which is not uniform, and the changing properties of the tool as the teeth sharpness reduces. It really is not suited to cnc programs.

    Saw-burning-wood issue may be due to two primary things. 1. chain needs to be constantly oiled to reduce friction between bar and the chain. Oil runs out quickly on small saws, and some small electric saws only have a manual oil pump. 2. The pole saw is probably designed to not cut well, or at all, at its tip to avoid kickback (ie. designed to only cut with flat section of blade), as you figured in your analysis. Carvers use their blade tip lower edges to carve tight spots. The amount of material removed with each tooth is controlled by the height (depth) of the point in front of the tooth (depth gauge). But you probably already know all that.

    I am a chainsaw wielding professional, and I can make your chain cut happily at the tip, and if the torque is sufficient I can make it cut even with your low chain speed saw.... if you want to take another gander at that send me a couple chains and the bar you use and I'll modify them ;)

    Hey Shane! So I work at a saw shop, and if you do choose to keep working on this project it might be worth trying a different bar and chain - Stihl sells a nice carving bar, and if the anti-kickback is giving you trouble you could try a chain that doesn’t have kickback reduction (assuming the robot can handle the added load). I’d love to see this thing carve a real log!

    I think you approached from the wrong direction. By stating with a model and working backwards toward the code. You should start by studying how human carvers make their bears. The ones if watched seem to derive their basic shape I just a few cuts. Figure out how to code these, then autogenerate code from there. Also create a machinable model, rather than trying to force the saw to machine a generic model. Think about how many things you use every day that's shape has as much to do with what made it as it does with how it needs to function.

    Gradient based optimization will always get trapped in local minima (or maxima if you put a negative sign in front of the objective function). You could have tried a technique called monotonic basin hopping. It might not have worked, but other alternative methods can get far more computationally intensive. We deal with this problem all the time in interplanetary trajectory optimization.
