Plasma cutting is incredibly useful. Paired with bending and welding it is often the fastest and cheapest way to build any kind of mechanical structure or enclosure. Results that might take a day on a 3D printer or on a CNC mill can be achieved in minutes on a plasma cutter. Not to mention the cost of sheet metal is a lot cheaper than 3D printer materials or billet for machining. I'm constantly making folded and welded structures with my plasma cutter and every time I have the same problem. I will design a complicated folded part and then when I go to bend it I can't place the bends accurately. I'll spend a lot of time trying to measure them out but the plasma cutter can make any arbitrary shape which can make measuring difficult.
To solve this problem I designed and built a pen plotter head for my plasma cutter. It allows me to first draw all of the bend lines then cut out the part. This gives me perfectly registered bend locations that make folding the parts really easy.
This video details how I designed it and how it works.

      He put in some unnecessary effort because only 2 positions were needed rather than 3. You could pull up to toggle whether the tip is out and push down to either write (if the tip is currently out) or rest (if the tip is currently retracted). Or did he need more than 1 tips' worth of clearance for some reason?

    10:00 a tip I learned from an electrician. At the beginning run a rope through the rig to pull your cable. Instead of pulling just the rope and cable through, attach a second rope behind the first with the cable. Then you will have a rerun rope every time for the next pull. Assuming of course the conduit isn’t full.

      Seems like you could just have one big rope in a loop, and then temporarily attach any other cable to it and pull it through

    One thing I learned going to school to be a sheet metal worker, was having the plasma cutter pause for a minute at the point where you want to break so it creates a small notch, All you have to do is line the notches up and boom a point to bend at.

    I did something similar on my table but with a carbide scribe with replaceable inserts. It has a compression spring on the z axis to compensate for material height inconsistencies. On 304ss or aluminum it works great. On hot rolled steel I need to run the g code a few times over to get through the mill scale. It makes for a very accurate bend line. Love your channel, you are one smart dude!

  • Ole Sauffaus

    IDEA: You could score the metal with a pointy tool, rather than drawing on it with a Sharpie. That would probably simplify the mechanics needed to make it work, and eliminate the "thickness" of your lines.

      @NG Wouldn't plasma etching risk significantly changing the steel temper and/or strength?

      I would use that blue stuff to scribe the lines or if you just used a regular scribe tool like when you're marking on a lathe. It's just a fine surface scratch it's not going to effect the strength of the metal or add any extra stress. Also with all the money he spent to get all those different CNC Machines, you would think that he would own a bending machine

    Hi... your videos are truly inspiring, innovative and with a crazy amount of engineering .. one very small suggestion is that you could use a 5/3 mid position exhaust solenoid valve + check valve crosspiloting (to stop wherever u want in the middle using just logic) instead of a 5/2 and not worry about using external springs totally... I can draw up a pneumatic circuit if you would like .. Anyways thanks for all the creative videos.. :)

    Awesome build! If you tie a string to your green ground wire and pull it back thru the wire track you can route a fishing wire to pull multiple wires back thru instead of removing the caps .

    9:52 you already have cables that go through the Energy Chain, so you can attach a long auxiliary Rope to the end of one cable A, you pull out the cable A (and the rope also goes through), then you tie the new cable B to the same end of the Rope where the cable A is already attached... so then you pull back the rope with both cables, and voilà!

    When I was a CNC operator at a fabrication shop, I would use a Sharpie to layout the cut locations on sheets prior to cutting. I'm loving that someone else does this on a whole different level!

  • Gogglez

    1:45 Just model in small bend notches to see where the bend lines are when forming. (If external bend notch, grind off the mark afterwards. Use internal bend notches where the visual looks are not important.

  • Shaun Muscat
    Shaun Muscat

    Very very brilliant and time saving idea well done. I was thinking that maybe instead of the pen, you may can fit a Laser engraving head . In my opinion it will mark much more precise guide lines for bending and would eliminate the wear on the tip of the pen also :) Well done for all your videos , very interesting to watch

  • Vaschka Koboroff
    Vaschka Koboroff

    Hey mate, Absolutely loving your videos watching them consecutively as we speak. if you notice this comment than it may help you or someone else that finds routing cables or tubes frustrating. I've laid cable in conduit professionally and all you have to do is feed a rope through once. Leave it there for the next time you return. tie or tape on the cable or tube you want to feed through and also a new piece of rope to go along with it so when you pull said cable or tube through you also have another piece of rope that has reset it ready for the next installation, in your case the distance is so short it most likely will result without having to remove any of the plates. I know this information is miniscule but its the little tricks of the trade that make the biggest difference, As you would know sir.

  • holsen78
    holsen78

    Instead of having to draw the bend line with a sharpie, you could just cut a couple of grooves where the bend should be. This would make the bending easier and if you're welding it anyway I think it would have little impact in the overall strength. Though I really do like the idea and design of this sharpie setup c",)

  • youdroids getoffmylawn

    Great idea. Thank you for posting this.. I didn't know those pens existed.. Had been recapping at the end of sessions. Have been using a spring loaded holder to moderate pen pressure. Pneumatic retractor Is simple yet effective. Nicely done.

  • Soul-Burn
    Soul-Burn

    For the cable routing through the sleeve, keep a plastic wire routed there. When you want to route a new cable, connect another plastic wire and the wanted cable to it. Pull from the other side, and you'll have your new cable and another "routing wire" routed, ready for the next time!

    I’m just amazed at the way his brain works. Like I understand that once anyone becomes very knowledgeable about something they can do great things, but this seems different.

    5:30 you could also use two cylinders one as a stop for the one that moves the pen. Extend the stop and the pen will only move to the stop.

  • Erwin Slootweg
    Erwin Slootweg

    about those wires in the wire guide, when i used to do networking cables for a server room that kept changing, i always had a piece of rope put through along with a new cable. i could use that piece of rope to pull another cable and piece of rope in the future without undoing ducting. might be an idea for you on some machines. nice vids you make :)

  • Leo's Bag of Tricks
    Leo's Bag of Tricks

    I make parts like this from laser-cut aluminum, I always put rows of holes or slots along the bend lines. I don't have a bending brake, but the holes make hand-bending really easy. The parts are slightly weaker, but the problem of where to bend is eliminated and accuracy is great.

  • seansverige

  • Taras Borisevich

    Regarding stringing cable chain on the plasma: Next time you have to add a wire, tape another piece of scrap wire or cable and push both through. Then the next time you have to add a wire, take another wire scrap and tape both to the first scrap piece and pull through, leaving you with another pull wire for future mods. Rinse and repeat (:

  • ModernSurvivalists
    ModernSurvivalists

    Amazed by all the engineering here! One quick tip that might help with future cable routing in your cable guides. Use a flexible sheet metal fish tape. You can attach various heads (small plastic 3d printed ball for example) so that it won't catch in all the crevices. Then use it to pull a nylon pull string. Whenever you pull something thru with your pull string, attach a second pull string along with it - so you still have one for next time!

    Note, you can just put springs inside the bore of an air cylinder, and not have to worry about a separate mount. The end caps should just thread off and let you stick it in there. I used this trick building a pneumatic 3-speed gearbox and it saved a lot of space and mechanical complexity.

    9:50 As a fellow CNC operator there is a simple solution to this particular problem. Mine just so happens to be 250 lbs. fly line backer. Fly line backer is braided line perhaps 3/32” in diameter and is relatively slick in nature. It is super easy to install also. Just tie it to one of your previously installed cables in the cable tray then disconnect and pull out the cable. Mark the fly line 4” below the point where the line stopped feeding back into the cable tray. Then pull the additional line out through the tray until you get to the mark. Tie a small weight to the other end of the line. Reattach the cable to the fly line ABOVE the mark on the line and pull the weight to ‘fish’ your cable back into position. Installation of this line should take less time than me typing out these instructions. I use a bent paper clip to secure the one end to the flex cable tray and a simple bread tie to gather up the excess at the other end of the tray.

    The correct valve for that would be a 5 way 3 position with a center exhaust. The center position with no voltage applied to the solenoids would let the cylinder float letting the springs do their job to center the cylinder.

I like learning, and I would like to learn how I could be able to do stuff like you do.

    Pro tip for conduit and "energy chains" run your first cable with a strong twine like rope. Then you can pull your next wire through and another strand of rope. Always have a pull rope that way. Takes just a few seconds to tape and untape as necessary.

    Very cool, I am curious how you get that g-code though. I assume that normally a cad program would generate that for you but with this you need to inject a bunch of g-code before and after certain paths in the design, or what do you do? And also did you have to add some extra controller board to execute special g-code for the marker clicking/lowering or can you just add that to the programming of your current cnc brain?

    You should leave an unused wire or tube in the energy chain with a couple of loops in it. Tie the new wire to one loop, and pull it through. To make is more than one use, tie another wire (besides the one your going to leave) to make a circle so you easily fish it through.

    The Hypertherm machines we use have a "scribe" mode which, operating at a lower amperage, only mark the metal surface. Same torch, no offset required.

    Awesome build!! One question, what is that tool you used at 8:00 to hold the nut in place? The one which looked like a spinning top? Also it would be great to mak it open source, both CAD and SW if you are not planning to commercialize. Ciao
