For 30 odd years I worked for a spring making company, during which time computer-controlled machines of increasing flexibility gradually appeared, making compression, tension, and torsion springs as well as wire shapes. I've been retired now for 13 years, so it was quite amazing to view your video which demonstrated the principles upon which these machines worked. It would have made the problem of explaining what we did to lay people a lot easier. My own contribution to the company was in designing and making electronic devices to improve the functions of older, non- computer-controlled machines. Although I made my own printed circuits boards, the designs were initially based on TTL integrated circuits and latterly Programmable Logic Controllers - nothing as advanced as Arduinos. What would I have given for a 3d printing machine ? I was also responsible for our computer system, in its metamorphosis from a punched-card system (with a 2K hard disk!), through unix based COBOL, to an Informix relational database system. I learned to code in many languages, so your program explanation was also fascinating to see. Thank you so much for posting this project, I found it most interesting.

You have really done a fine job with this! I’ve seen the large commercial units that cost mega-bucks to acquire but this is an amazing workaround for folks on a budget. The best thing is that you have done such a nice job documenting your work. Thanks so much for being a class person and passing on this great information.

This is one of the best Arduino projects I've ever seen! The video quality is great, and every step is explained in details, so that everyone can build it. The narration is great as well, you're getting better and better with each project! Keep up the amazing work Dejan!

This is a really fantastic project, initially I thought the demonstration was just a computer generated graphic but later discovered that it is the real deal... Great work, more of this please!!!

Hey everyone, thank you so very much for the positive feedback and motivation! I will definitely keep making this kind of content, so stay tuned! 😉

Fantastic job, so refreshing to see someone who doesn’t use hot glue for everything. 👍🏻

There are a lot of preventative measures and quality assurance modes on this that I can appreciate. From one engineer to another, good job

This is a very cool machine, and a very well documented project. Thank you for sharing.

One of the best 3d print project videos on UKposts

you make an complex topic easy and fun to understand. very nice, i hope u keep uploading content like this :)

I'm a EE., my kids are interested in engineering and they would LOVE this project, please keep this stuff going man!!

Exceptional thank you. I’ve been building a wire bending spring maker that I found on instructables which is really good and to now find your clever invention will give me not just an alternative wire bending machine but also a deeper understanding of all that is going on both with the mechanics but even more importantly, with the coding which I am quite new to. Thank you for a clear, simple and easy to understand explanation, it is of great value to me personally and I am very grateful, thank you 😎

I learned how cool this would be to be able to do. And i also learned, just how much easier life is when you have a very nice 3d printer! nice vid

You are one of the brightest minds in practical engineering I ever saw on UKposts, I wander how many times you failed for doing this amazing piece of machinery

Everything fits perfectly... Beautiful to watch.

Very nice build! It's the first project I've seen that makes me think that I might have to add a 3D printer to my shop! For your straightener/feeder problem at the end, I'd suggest either gluing a strip of sandpaper to the copper tube in the feeder for extra grip, or perhaps using a rubber roller (salvage from an old printer or such).

today i learned something very special from you. i love wire products machinery. thank you so much for your ideas. 👍🏻

You sir are a Genius! You are doing mechanical engineering, Computer Aided Design, Custom Fabrication, Electronics Engineering, Computer/Software Engineering, Video Capture, Editing and production, Narrating, and at least 5 more things I am not smart enough to think about all by yourself. It would take a multi-disciplinary team of competent professionals to accomplish what you can accomplish all by yourself. Bravo! and Much Respect!

Awesome. It is a nice piece of engineering.

Fatastic!!! This is amazing in so many levels. And your shop so clean 👏👏 I love the insert nut on the gears to secure them to the axle 👍

3:15 - I really like the way you designed the gear to accept nuts. I'm going to use this in future designs! Thanks for the great idea! Feeder issue: Perhaps have two drive wheels tied together with a gear on one side of the wire, then have two pressure rollers with a tension spring on the other side. That would double the area and grip of the unit.

Had a cup of coffee and watched this video. Wonderfully simple, very well explained - and certainly inspiring!

Well done, HTM! This is quality content. The machine is well-built. I like how everything is custom designed (including the PCB, gears) and no hot glues or temporary wires are used. You use nuts and screw correctly to hold the motors in place. Your video is quite in-depth and explains the details and how-to pretty well. I've subscribed, definately looking for more!

I have to agree with the majority of the commenters. Great build. Excellently documented. You explanations are clear and precise. Even considering your comments regarding the flaws of the machine is awesome too. You have just gained a new subscriber. Regarding the feed issues. Mig welders often use a knurled wheel as well as a bearing wheel. So perhaps try that instead of the roughed up copper tube. Also. The straightener part of the machine. . When using a similar pipe straightener machine, you pull the pipe in and out of the straightener a few times. Maybe you could feed and return the wire through a section of straightener a few times before starting a bend program? Only thing it needs now are automated wire clips to clip the wire off once finished. Very well executed.

I really appreciate the time and energy you've put into making this.

If I may comment, yours is one of that roughly 10-20 percent of videos of an instructional/educational nature that is fairly well put together, clear in explanation, and generally well done.

I love JLCPCB, everyone that they sponsor literally uses their product in the subject of the video and its pretty great.

Excellent video... I used to work in an shop where we had straighteners to take the bend out of coiled steel just prior to fine blanking. The straightener rollers WERE the feed rolls. The straightener rollers were geared in series and they did the feeding of material. To compensate for feed roll slippage, there was a single roller that counted the feed length. On your system, you could make the five straightener rollers into feed rolls and rework the current feeder roller into a potentiometer that counted distance and shut the feed off when a given distance was achieved. Thanks again for a great video. Thumbs up and a new subscriber here.

wooooooow 😍 🤩 I'll build it to my mom she really loves making shapes with wires thank you so much 💪🏽🤤

By far this is the project/video that I liked the most. This is not only excellent to teach mechatronics, but also an excellent example of the usefulness of many tools combined to make a real machine.

*I appreciate JLCPCB* for sponsoring videos like this instead of sending spam emails. I cannot get rid of spams from JSD PCB and other PCB companies which I ask for a quotation once. *Extra tip* about asking quotation from "some" PCB companies: use a disposable e-mail address.

I dreamed about this stuff as a kid and now as an adult still amazes me. A 5 axis cnc bender is about 150k, I love you can get a functional prototype in desktop size. Also never realized PCBs could be so cheap to have made.

Hi! thanks for the video! I worked with a bending machine in an industrial setup (rebar bender for reinforced concrete) and it's pretty close to it, now I work in a factory that make MIG welding wires and we use straighteners almost like yours, I can give you some insight that we learned: first, you need to mount the three rollers individually, you will have more control on the straightening. Next, if you don't or cant have much pulling force, you should add more straighteners (with that you can equalize the straightening force on multiple rollers and alleviate the strain on the drive mecanism) and I suggest to add a vertical one too (that will help with the overall straightening and your wire will be straight in both axis). Now, for the pulling system, I recommand you to search about MIG welder wire driving systems, it's EXACTLY the same as you seek to achieve here. Here is an example: cdn.eastwood.com/media/catalog/product/cache/1/image/9df78eab33525d08d6e5fb8d27136e95/p/1/p12012_3.jpg the bottom roller possess a groove and is motorized, the upper one pinch the wire on the groove, it is mounted on an arm and locked with a tensioning screw, it serve as a quick lock for the arm and it apply pressure on the wire that you can tune with the knob. I hope that my humble experience will help you :)

This is one of the best practical demonstrations of the fundamentals of mechatronics that I've ever seen. Physical manipulation and mechanical feedback of/from the environment, electronic interface to process and give action to the software commands/feedback, custom-coded software running the show. All the principles you need to learn, in a really nicely engineered demo project. Excellent work, 10/10, new sub here. Happy new year from Australia mate, all the best for 2019!

Very impressive! As other comments have pointed out, you have very high level knowledge and skills across many disciplines. Show this video to any potential employer and you'll get the job. Will give JLCPCBs a try. Your board looked very nice BTW.

awesome!

Great project! You mentioned at the end that you were having a problem feeding the wire due to slippage. If you borrow a design from a MIG welder feeder you can see the feeder pulley/gear has a knurled toothy grip where it contacts the wire. Perhaps you could get hold of one of those drive gears to use. As with many of your previous projects you have unique and what appears to be original ideas. Keep up the good work.

Amazing, mechanic, electronic and software analysis, design, manufacturing, implementation, integration, testing, debugging...all in one amazing project/product! Congratulations!

Thank you for this! I want to start my son into some fun projects and this is over our heads to start but something to work up to

Crude, but its a very good start! I like it. I find the combination of both open source components, and 3d printed parts, a nice touch! Well done.

WOW! Man! You are awesome! Thanks for posting! Subbed!

Great job on the pcb it turned out very clean!

I was just thinking about trying to make one of these yesterday! You saved me some work! Thank you!

It is amazing that so many creative projects can be made using arduino and raspberry pi !

Very cool project!

Interesting, usefull medium level , this is a project that is quit in reach for most ! Love it !

That's some very fine work you did. I really love when electronics, software and mechanics work together.

Very very nice project! Bravissimo!

Very interessting, great Job!

this project video is one of the best Arduino tutorials I've seen, and the wire bender is awesome! Great job showing as well as explaining everything. Thanks!

This is an exceptional use of coding and 3d printing awesome build! I could really use something like this for automating wire bending for through wire fishing lures.

I noticed a few people asking for upgrades to this. My suggestion would be to add an OLED screen, rotary encoder, an SD card reader and wire cutter. The SD card allows feed and angle data to be added from a file. The rotary encoder allows file selection input. The OLED to give feedback to the user. You could even use the encoder to enter data manually. Making the unit stand alone. Scaling options. With wire cutters you can program it to make 'x' amount of shapes. Again. Great project.

That 7805 voltage regulator must get pretty hot going from 12 volts down to 5 volts.

Wow. Awesome. I've done piping design for years. We never had a machine this capable, this affordable.

I didn't know I needed this in my life but now I do!

I'm a new viewer. Only minutes into watching my first video, I'm already subscribed. Great build! I wonder if it could made to run something like GRBL.

Really cool project!

Great job. Its great to see such a sophisticated machine being designed so that regular people can reproduce it. Its like magic seeing it work.

Excellent, the 3d printed parts came out very nice. I never knew a custom PCB could be made so cheap!!!

Use a mig welder wire feeder it's cheap but you can replicate it in 3d software. Amazing work!

Wow, Really Amazing. So cool to be able to create a true physical computing solution.

Absolutely amazing; stunning video!

wow!! super amazing!!!!!!!! loved this project!!!!! Cheers from Argentina!!!!

The people who have this a thumbs down are plain haters ! This is awesome !

I don't think I've ever seen anyone custom order a PCB and then use it as a breadboard.

Excellent! I've been wanting to make one of these ever since I saw the original DIWire video (which I'm please to see you credit). You've done a nice, straight-forward version that I'm looking forward to building, and a great tutorial.

Thanks The creator i have found my mentor .will u be my mentor

You win the Internet today. Treat it well. Fill the tank with gas before you bring it back.

Really impressive! I could use one to do initial modelling of ideas. :)

I make compression springs and wire-forms at work. Your project is really good, well done.

супер!!!

1:00 that hurt my brain so much😂

This is genius! Thanks for describing the steps so well!

Great channel, i just discovered you today! I like the detail and clear explanations, keep up the good work.

Take a shot every time this guy has a voice crack

В акценте и обстановке разглядел сородича)

This is wonderful! What a great project and what a clean execution! ... Great Job!

Such a great and well documented project. Thank you for sharing it.

You get voicecraks 😂

Anyone watching this video in October 2019?

Amazing work! One thing to say.. It's just.. Perfect.

I don't have a purpose for this, but I feel like I have to make one now. This is one of the coolest projects I've seen. Great video and instructions, too. Thanks for this.

How many voice cracks can someone have??

Ok great content but omgggg fix your voice cracks.

Extremely cool! Looking forward to exploring making something similar at some point

wow i mean it's soooo detailled project and everything is in his place, love people like you that can't keep a place for a mistake

3:33 oof voicecrack

На русском есть видео?Ты же кортавишь как русский.

what a great video. I will also make this project myself. thanks.

Bend wires? pfft.... you bent my mind, man. Well done. Gonna make a thing now myself

This is one of the coolest projects I have seen in a while, presented in an enjoyable Video! Thank you very much for sharing and thumbs up!

Great video, just finished a digital electronics program and loved it, this video shows one of the best arduino projects on internet, mostly they are for fun and nothing really elaborate, this provides new ideas and new applications, thank you

I liked your video so much because you explain the coding too, I saw many people make different thing but they don’t say how to code for that.

Great job, I plan on building a spring coil winder myself one day.

Congratulations! An excellent project.

This tutorial is really well explained and this project is pretty cool!

Undoubtedly one of the coolest project videos I've seen. Awesome.

Very nice machine. For the feeder problem perhaps what you need is some spring loading on the lever that presses against the feed roller. With just a tightening screw it is difficult to keep constant pressure on the wire.

In my comment about BOM, after viewing the video again, I think the way you displayed the cost of the PCB was great.
