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.
Hello @Don Johnson24 I find your comment and work on the machines very interesting! If there were videos on the subject made by you (e.g. your PCB designs, TTL circuits you worked with, PLC logics, most importantly Unix and even how those punch-card systems and COBOL worked) I'd be very interested to watch them. Thanks for adding your input on this video, I always find stories like this very fascinating. Have a great day!
This is one of the most well written comments I've ever seen! I feel obligated to capitalize and punctuate everything from this point on. These explanations of how processes were executed should be standard curriculum for all mechanical engineering degrees. Every ME should buy a cheap 3D printer and an Arduino kit . It honestly takes about 8 hours to learn it. I learned it and use it everyday for my actual job. It's like unlocking a cheat code for a video game.
Супер видео! На крајот можда ако ставиш гума и на цевката и на лагерот (парче внатрешна гума од точак на пример😉) би се решил проблемот. П.С. Не би било лошо да ставиш captions на македонски. 😉
Oh man, you really show us that the imagination and creativity have no limits... thanks a lot, I've learned a lot with your videos!!!! What a beauty machine!!!
well done, very informative. As for your wire feed problem, have a look at MIG welders, how they feed the wire, also they use a spring tension with the bolt adjusting the tension, this allows for the fractions of an inch variations in the wire. Also, larger industrial machines used a hardened knurled drive wheel, which grips the wire, again which should be cheaply available online in a variety of sizes. Also pushing soft wire thru the copper tube, it has too much room to be able to bend, perhaps get pvc tube in different sizes and slide on inside the other and side the whole lot into the copper, or print something. It's a bit like trying to push a rope up hill, put it in a tube and you can do it, put it in a huge pipe and it will bend and fold over inside.
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!
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.
I used to run a wire bender. it's amazing how simple it CAN be on the small scale, large scale is a different story. Great job on your project, happy that it works well.
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).
Alternatively, a very simple solution to the feeder problem would be to put some heat-shrink tubing over the copper tubing. Should raise the coefficient of friction enough to solve the slipping problem.
@@JimmysTractor Not a bad idea, but if your tension is set too high, it will leave marks in the wire. If that's not an issue, that's a great idea. It gives you plenty of grip, and makes a good positive connection between the roller and the wire.
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!!!
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.
I was going to suggest putting a backing roller on the opposite side of the feed roller, so more drag force could be applied to the feed without increasing the lateral force on the servo shaft . . . but I think you have a better suggestion. I would replace your distance-counting potentiometer with a rotary shaft encoder that sends a pair of phase-lapped pulse trains to the arduino for measuring distance, though.
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.
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.
If you're working with flat shafts and you can just put in a 5mm screw hole, you can use the regular self-threading plastic screws (like what PC fans use), instead of needing nuts. The screws are cheap, and it works really well for securing a plastic part to a shaft.
You are one of the brightest minds in practical engineering I ever saw on RUclips, I wander how many times you failed for doing this amazing piece of machinery
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.
Thank you! That's a good tip, pull in and out the wire several times before feeder to the bender. However, first issue to be solved is the grip of the feeder. Thanks again for the input!
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!
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!
@@HowToMechatronics How about turning the straightening rollers into a variable-pressure extruder with directly opposed rollers in horizontal/vertical planes... So you could program different round/flat/square wire profiles in different sections of the produced shapes? It's a lot of extra engineering, but should be simple to implement on the software side. Is it possible, what do you think? 😁 Maybe a linear actuator would have enough holding force to apply suitable pressure to a copper wire, or maybe you need some kind of gearing-reduced servo/stepper mechanism to adjust the distance/pressure of the rollers?
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 :)
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.
Thank you and thanks for the input! Yeah, the feeder in my design definitely needs some improvement. The first thing that I noticed is that the copper tube that I used, is actually softer material that the steel wire I was bending. So even when I tried to make some teeth to the copper tube, the material was week and got squashed by the wire. Also, when I tried to tighten then feeder more, the 3D printed shaft coupler broke, which means that the way that two rollers (the feeder and the bearing) are position is not quite good.
Or a direct-drive filament extruder assembly for 3D printing. Should easily mount onto your existing NEMA stepper and give you a knurled gear drive that should work. Not sure of your wire diameter but the filament is commonly 1.75mm so you might need to adjust a bit.
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!
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.
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 don't find that amazing at all. A computer/microcontroller is today the first choice to implement almost anything. What is amazing that thanks to computer revolution we now can buy literally millions of transistors at a few cents/dollars/euros. Even more amazing is how come Arduino and Raspberry PI have become so popular when there was nothing special about them in the first place.
Yes! Today a microcontroller or raspberry pi is easy to operate. However, a decade back, it was intimidating for anyone without prior knowledge of microcontroller to prototype electronic projects.
10:24.. It's a relief to see that you know how to solder properly. There are too many Y/T channels like "Great Scott" and "Julian Llett" that have no idea or clue as to how to solder properly.
*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.
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!
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 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.
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'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.
Thank you! Well to be honest, I couldn't afford more time in making the program more functional. Maybe in future video I could make a GUI, probably using Processing IDE, where you can draw a shape on a canvas, and then send the shape to the Arduino using the serial port, and the machine will make the shape . But like I said, it takes time to make such a thing, so maybe in some future video.
Just amazing work, absolutely amazing! I'm new to IOT and so glad I found your channel - you have so many relatable projects to work though! A friend gave me about 20 esp32 boards so I'll be modifying from your work slightly but still learning nonetheless.
I just fell on to this video some how. I am not an engineer or technical person at all, but this was so interesting. I thoroughly enjoyed it and understood it. Thank you and good luck in your career.
Excellent engineering, video, narration, and documentation! The only alteration that I can recommend is the problem with the feeder stepper slipping, using a pulling spring from the other side instead of the bolt on the lever. Liked and subscribed!
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.
instead of using flat wheels or rollers to feed the wire, you need to make feed wheels with a grove machined around them to match the diameter of the wire being fed. The grooves need to be textured, then one wheel needs to be stationary while the other has adjustable spring tension to apply pressure on the wire. Then your wire straightener will work flawlessly.
Great job. Amazed that you can get a custom designed circuit board made for $2.00. You should add a spring to the tensioner to give you pre-load on the wire and better grip!
you let me be proud of our Mechatronics.. keep showing them what knowledge - and integration of knowledge - that we have ... keep up this excellent work ...

Commendable undertaking with outstanding results. The 3D printer is again demonstrated as an indispensable tool in the hands of a skilled maker like yourself. Thank you. Years ago where I worked in a airplane factory, there were similar machines on a larger scale, that were use to produce complex hydraulic lines by the hundreds. I don't think they were computer controlled though.
Excellent job, I am very happy to see your machine, cheers... keep it up. Ignore those thumbs down may be those people do not know that this video is for technical people.
Great video. Just a thought. in a mig welder the wire is fed in a similar way. The spools of wire are heavy and the feeder works similar to your feeder or pulling you are doing but it has a grooves that the pressure is set with a screw and a spring that puts pressure on the Drive Roller wheel that puts pressure on the wire that is being pushed and pulled at the same time. It would be easy to try. Just a thought. Great project.
Nice setup try using puch springs for transfering pressure from set screws to he wheels at the feeder and straittner. Also in between the straitning bars put two weaker springs To keep the distance of the bars when not in tension.
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.
brilliant!!!Go for a 3D Software to generate a gcode. May be emcRepRap could be a starting point. Your steppermotor knows the distance. Eventualy a metal "nossle" ... the inside of different ball bearings.

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.
Nice work but plz create a code for reading .svg and .obj files and then adjusting bends maybe with the use of processing. And then it is complete.
Hi . . Jason
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.
Thank you!
One of the best 3d print project videos on RUclips
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.
Thanks!
awesome!

Oh are you here bec you needed to bend wire for the marble droppers and marble railings

That's some very fine work you did. I really love when electronics, software and mechanics work together.
I really appreciate the time and energy you've put into making this.
There are a lot of preventative measures and quality assurance modes on this that I can appreciate.
From one engineer to another, good job
It is amazing that so many creative projects can be made using arduino and raspberry pi !
Yeah, they are amazing! :)
I don't find that amazing at all. A computer/microcontroller is today the first choice to implement almost anything. What is amazing that thanks to computer revolution we now can buy literally millions of transistors at a few cents/dollars/euros. Even more amazing is how come Arduino and Raspberry PI have become so popular when there was nothing special about them in the first place.
Yes! Today a microcontroller or raspberry pi is easy to operate. However, a decade back, it was intimidating for anyone without prior knowledge of microcontroller to prototype electronic projects.
10:24.. It's a relief to see that you know how to solder properly. There are too many Y/T channels like "Great Scott" and "Julian Llett" that have no idea or clue as to how to solder properly.
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 👍
*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.
BTW *thank you for this awesome project* !!!
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
A nice project and well made video. I am considering studying mechatronic engineering and your video has increased my enthusiasm for the field.
Thanks!
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.
Thank you!
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
heh thanks again! Yeah, I sometimes feel like I'm doing something wrong because I go into so much details.
@@HowToMechatronics keep it like that we all love that master, thanks for that
you make an complex topic easy and fun to understand. very nice, i hope u keep uploading content like this :)
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!
Thank you!
today i learned something very special from you. i love wire products machinery. thank you so much for your ideas. 👍🏻
Nice to see an engineer that can for REAL actually solder correctly, kudos
hehe thanks! :)
@@HowToMechatronics :)
Awesome. It is a nice piece of engineering.
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 😎
Use a mig welder wire feeder it's cheap but you can replicate it in 3d software. Amazing work!
Bingo. Might be able to get replacement parts for a wirefeed welder as well.
@@DavidCAdams you can buy a mig wire feeder on ebay very cheap. If you like to spend more money you can buy a branded one and better quality.
Why don’t you put some heat shrink tubing around the copper tube first and see if that helps. Coolest project I’ve seen yet. Keep up the good work.
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.
Everything fits perfectly... Beautiful to watch.
I'm a EE., my kids are interested in engineering and they would LOVE this project, please keep this stuff going man!!
The people who have this a thumbs down are plain haters ! This is awesome !
No cutting gloves man...
Wow. Awesome. I've done piping design for years. We never had a machine this capable, this affordable.
That 7805 voltage regulator must get pretty hot going from 12 volts down to 5 volts.
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.
Thanks! :)
Wow, Really Amazing. So cool to be able to create a true physical computing solution.
Thank you!
One of the best technical videos I have seen.very well executed, very well documented and very well explained. Thanks
I'm glad to hear this, thanks!
wooooooow 😍 🤩 I'll build it to my mom she really loves making shapes with wires
thank you so much 💪🏽🤤
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!
Thank you! :)
I don't think I've ever seen anyone custom order a PCB and then use it as a breadboard.
Modularized design, not really a bread board, but true.
yea that was kind of a waste, sockets for JST connectors are not expensive and would have made this thing so much better.
To make it easy to switch out the stepper drivers (since it's not hard to over-heat then) I presume.
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
Thank you!
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.
Thank you! Well to be honest, I couldn't afford more time in making the program more functional. Maybe in future video I could make a GUI, probably using Processing IDE, where you can draw a shape on a canvas, and then send the shape to the Arduino using the serial port, and the machine will make the shape . But like I said, it takes time to make such a thing, so maybe in some future video.
It should just work using GRBL (with some basic GRBL config) G-Code would instruct the machine.
This is a 1st class video presentation. Everything is good from beginning to end. Very professional.
Thanks!
Very very nice project!
Bravissimo!
Thanks!
In my comment about BOM, after viewing the video again, I think the way you displayed the cost of the PCB was great.
WOW! Man! You are awesome! Thanks for posting! Subbed!
Thanks!
I think the same, I also subscribed ;-)
I make compression springs and wire-forms at work. Your project is really good, well done.
Really cool project!
You say it. It's so amazing.
Very impressive. Shame it lacks a means to do variable radius. The straightener should be retrofitted to assist wire feed. Very impressive.
You win the Internet today. Treat it well. Fill the tank with gas before you bring it back.
Too funny 😂!
Bless
Excellent, the 3d printed parts came out very nice. I never knew a custom PCB could be made so cheap!!!
1:00 that hurt my brain so much😂
Just amazing work, absolutely amazing! I'm new to IOT and so glad I found your channel - you have so many relatable projects to work though! A friend gave me about 20 esp32 boards so I'll be modifying from your work slightly but still learning nonetheless.
Very interessting, great Job!
Thank you!
Another proof that arduino and stepper motors provide endless possibilities thanks for sharing
Exactly!

I just fell on to this video some how. I am not an engineer or technical person at all, but this was so interesting. I thoroughly enjoyed it and understood it. Thank you and good luck in your career.
Thank you, I'm glad to hear this!
Thanks The creator i have found my mentor .will u be my mentor
Excellent engineering, video, narration, and documentation!
The only alteration that I can recommend is the problem with the feeder stepper slipping, using a pulling spring from the other side instead of the bolt on the
lever. Liked and subscribed!
Thank you and thanks for the input!
Take a shot every time this guy has a voice crack
I'd rather not die from alcohol poisoning
puberty a bitch when youre in college level grad school engineering class lol
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.
instead of using flat wheels or rollers to feed the wire, you need to make feed wheels with a grove machined around them to match the diameter of the wire being fed. The grooves need to be textured, then one wheel needs to be stationary while the other has adjustable spring tension to apply pressure on the wire. Then your wire straightener will work flawlessly.
Anyone watching this video in October 2019?
no
Nope
I like how this incorporates many disciplines.
How many voice cracks can someone have??
Great job. Amazed that you can get a custom designed circuit board made for $2.00. You should add a spring to the tensioner to give you pre-load on the wire and better grip!
You get voicecraks 😂
Yeah, sometimes! :)
I realize it now, when you say it ;-)
Rude
you let me be proud of our Mechatronics.. keep showing them what knowledge - and integration of knowledge - that we have ...
keep up this excellent work ...
Ok great content but omgggg fix your voice cracks.
Good job. I would suggest adding the cutter at the end phase.

Commendable undertaking with outstanding results. The 3D printer is again demonstrated as an indispensable tool in the hands of a skilled maker like yourself. Thank you.
Years ago where I worked in a airplane factory, there were similar machines on a larger scale, that were use to produce complex hydraulic lines by the hundreds. I don't think they were computer controlled though.
Thank you! Yeah, 3D printers are really amazing, especially nowadays when you can get great print quality with decent priced printer.
3:33 oof voicecrack

Really nice video! I think this is a wonderful use of 3D printing and CNC. Thanks for all the effort to make the video!
Thanks!
супер!!!
Excellent job, I am very happy to see your machine, cheers... keep it up.
Ignore those thumbs down may be those people do not know that this video is for technical people.
Great video. Just a thought. in a mig welder the wire is fed in a similar way. The spools of wire are heavy and the feeder works similar to your feeder or pulling you are doing but it has a grooves that the pressure is set with a screw and a spring that puts pressure on the Drive Roller wheel that puts pressure on the wire that is being pushed and pulled at the same time. It would be easy to try. Just a thought. Great project.
Great channel, i just discovered you today! I like the detail and clear explanations, keep up the good work.
Nice setup try using puch springs for transfering pressure from set screws to he wheels at the feeder and straittner. Also in between the straitning bars put two weaker springs
To keep the distance of the bars when not in tension.
You could use welder wire feed wheels same type of mechanism but with grips on the drive wheel surface ? Fun project !
Undoubtedly one of the coolest project videos I've seen. Awesome.
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.
brilliant!!!Go for a 3D Software to generate a gcode. May be emcRepRap could be a starting point. Your steppermotor knows the distance. Eventualy a metal "nossle" ... the inside of different ball bearings.
