I am amazed at the shear number of elegant solutions implemented on this machine, everything from the cooling blocks on the steppers, the permanent magnet head holding workspot, and even little trash can in the frame. It seems like every issue I have ever had with my printer you've got an answer for. You are one hell of an engineer, thank you for posting this!
Oh what a difficult choice I have to make. Tap changer, or this. This looks easier to deal with and more reliable. Especially wirh a laser, dremel,cutter and other tool types. I really like the easily removable bed. Plasma cutter bed would swap nicely !
félicitation , cette imprimante me parait bien complète , beaucoup de chose très intéressante , changeur d'outil , la récupération du centre des buse ,... je suis moi même en pleine conversion d'une anet E12 en voron trident , un jours peut être aurais-je aussi un changeur d'outils.
Hi, very fun looking project to design and build. You may have inspired me to look at a tool changer for my custom machine. Look at the duet 3 with tool changer boards it could potentially make your wiring a lot cleaner and easier to manage. Thanks for this really cool video.
Wow vraiment bravo pour cette vidéo, j’ose pas imaginer tout les cheveux arrachés sur chaque problème que tu as dû résoudre. Je me posais une question: vu que le plateau d’impression est soutenu par trois moteurs indépendants, ne serait-il pas possible d’incliner (même légèrement) le plateau pour avoir de meilleurs overhang, moins de support, ou même de l’impression non planaire (je sais que c’est possible avec Marlin, donc ça devrait l’être aussi avec Duet). Super projet, impatient de voir comment ça évolue.
I'm speechless, you have to be a little genius to design, program and build something like this. I wish you a lot of fun and success for all further projects. In the hope 🤞😉 that you will continue to show us exciting things, I immediately subscribed to the channel. Best regards 👋😃
ah ah, thanks ! just an old engineer using a fantastic shared knowledge and quality software pieces . I try to put my stone by sharing my work if I consider it innovative. Which isn't so often :)
"When an engineer builds his own FDM printer" 😄😉. As a mechanic with an engineering background, I love the modular design and ease of maintenance build into everything. Definitely has an industrial / professional feel to it. Well done sir👍
Nice to see someone using an electromagnet, I've build a toolchanger with an electro-permanent magnet about 2.5 years ago. Many people don't like the electromagnets, but I do...
Уважение за проделанную работу, всё сделано очень хорошо и скурпулёзно,даже представить не могу сколько времени ушло на настройку что бы всё работало как надо👍👍👍👍👍
Just wrapping my head around this- The bed is levelled using the probe on the back of the XY gantry? then the offset from the nozzle to the bed is found using the piezo (which is fixed to the bed at a known offset)? very clever! where did you get the piezo / that blue pcb from?
I'm sorry, the industrial file isn't in a shareable state at this time and I don't think that it would be a good idea to start a new design on this basis. I'll do my best to answer to your questions.
This is truely amazing. Well done man. I cannot wait to see further developments for this. I feel like this is a project that can really evolve some aspects of printing. I would be interesting in making this someday.
Can you provide a link to the electromagnet you've used for this application? I really like your solution to this problem. Also I've been wondering for ages why no one has been using the nozzle detection solution you've implemented. Well done!
I’m humbled by your design and engineering skills. Thank you so much for sharing. I have to ask, what is your history professionally? Apologies, don’t mean to be invasive or nosy I’mjust curious how you buit your skillsets over the years. Whatever the case is,they are absolutely phenomenal sir. Subscribed!
Thanks for your comment Jack, To answer to your question I am an electronics engineer. I have worked on the development of hard/soft/mechanical products for various companies and I continue as an independent consultant. I love the creative process from idea to object and the elegant solutions.
@@workshopfeedback Thank YOU! That is fantastic.. IT Engineer here, getting into hardware/electronics/fabricating, etc…. Love it as well and your application of it is NICE!!! Elegant is what we should shoot for! Keep doing it and sharing!
@@adammilnesmith Hi Adam, You may start building something based on shared design like a drone, a RC car or a Voron 3d printer. Buy a simple 3D printer. Participate to a Fablab ...
@Workshop Feedback thanks for the reply! I'm currently renovating my garage so that I have a place to put a 3d printer and start building things. I hadn't thought about joining a FabLab or similar - great idea. I'm also curious if there's any good sources to provide structured learning of foundational level theoretical knowledge for mechanical engineering for someone with a strong mathematical background already?
wow! THIS IS AWESOME!!! Great job! Great crafting skills, I'm really impressed! I really loved the idea to change print heads with magnets, so you can make multicolor without wasting lots of filament !!👌
This is beautiful work. Well thought out and executed. I look forward to any and all updates and as in-depth videos you are able to provide. I am an immediate fan.
I am a 11 year industrial cnc (Maka) operator/occasional programmer. I make kitchen sinks for Blanc & Fischer in Toronto, Canada. I am extremely impressed with your progress. Please make more videos you're really doing good with the production of videos. Please make more. Every time you make a video makes me want to achieve greater and leave my dead end job. I'm worth a lot more. You inspire me.
Hello, What I think is a great and brilliant job you did with the printer. Is there a chance you would share your printable files and other information with me. You also received a private message from me via email. I send greetings from the Black Sea coast of Bulgaria
Hello, thank you for your messages. It is difficult to provide designs because the printer is a prototype and the video was intended to show the different concepts I used and how I implemented them. The design files are not in a shareable state. If you have any questions on various technical points, I will do my best to help you. My best advice in this type of production is to make a complete model of the printer in fusion 360 or another CAD software before starting manufacturing. Otherwise you can also start with a VORON type printer which seems well documented to me.
How fast can it print? Do the magnets limit how fast it can print? Fantastic tool changing printer, love the use of the flexible filament in the tool changer!
Félicitations pour cette vidéo, je voulais vous poser quelques questions : Comment gérez-vous les réchauffeurs lorsqu'ils ne sont pas en train d'imprimer ? Les laissez-vous à la température la plus basse et lorsque vous allez les récupérer, vous augmentez la température jusqu'à la température d'impression ? Disposez-vous d'un système qui détecte que le couplage des aimants a été effectué correctement ? Enfin, pourriez-vous partager l'appel que vous faites à chaque outil et ce qu'il fait ? Merci encore pour votre présentation.
Merci pour votre message. La température de la tête d'impression au repos est définie dans le slicer qui s'occupe de tout (j'utilise le slicer Prusa, je ne sais pas pour les autres). En général je la fixe 80°C en dessous de la température d'impression mais pour des impressions de petites pièce je peux aussi la maintenir à la température d'impression. Je n'ai pas de détection du couplage mais j'envisage d'en ajouter une. Les cas où le couplage échoue sont assez rares mais ça peut se produire. Il y a trois fichiers GCode pour chaque tête qui sont exécutés lors de changement de tête, deux à la prise et un à la libération. Voici le lien vers un exemple. drive.google.com/file/d/1E2GxQ0OWSCnhjabThB2Q1Rk5eDHvFi55/view?usp=sharing Cordialement,
What an impressive job. It truly reflects a professional job by a professional worthy of admiration! It's really satisfying to find these types of videos and projects. Congratulations!!
I am deep in the process of setting up an Ender5+ with mods from ZeroG, and I have been thinking about all these types of upgrades and quality of life improvements. The easy maintenance on toolheads is one of my main goals and I really like your solutions. I'm going to subsscribe in hope to watch your content for future inspiration.
Hello there, We have manufactured a machining tool for ASMBL (Additive Substractive Manufacturing By Layer) that actually works well, we can send you one for free, we have all the macros for duet2 wifi that works ! It would be nice to see if it works with your design ! Regards
This is an excellent design. I have been working on a custome corexy build for a few months now and really like your electronics and filament management. Great ideas! I’m making a 500 x 500 x 550mm size. My biggest issue is the bed warping being so big. Had to order a 6mm thick aluminum sheet and will have to make the bed myself. I plan to make it tool changing eventually and love your design. Great ideas. Good job!
@Workshop Feedback For how much force is the electro magnet rated? Any reason why you used not-magnetic when no-power compared to magnetic when no-power?
I love this so much and I will try to use this for my own toolchanger for sure! I have just one question: have you tried different strengths of electromagnets until you decided for the 34/25mm one? I am just wondering if other versions are also viable
Realy like your printer. I want to make basically the same type of printer by my self, but i was consuming is it even possible with home workshop supplies. Now when i saw your one, i totally gona make it!
@@workshopfeedback I came up with this design using a permanent electromagnet. There will be no heating of magnet and no dropping of head on power loss ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-8qZWVmBb7m0.htmlsi=ROECuBAK_hz26QeN
Beautiful printer and well thought out. Thank you sir for sharing. This is a very inspirational video. Hope to see more videos. Are you planning to enclose your printer so it can print high temp filament?
Yes, it can be done for the Z offset. I intend to add one probe under my bed to get a real Z offset between the nozzle and the bed. With my current XYZ probe, there's a setup constant reflecting the height's difference between the top of the probe cylinder and the top of the bed. If I change the PEI plate on the bed, I must change this constant due to the plates different thicknesses
Impressive design! I have one question regarding the electromagnet - did you consider making permanent magnet to hold the head and use the electromagnet to change the head? The electromagnet wouldn't be powered over the whole printing process, just when changing head.
I didn't try it. May not be easy to implement. That would solve the falling head on power loss problem but I'not sure the permanent magnet wouldn't get de-magnetized
@@workshopfeedback Thank you for reply. Good inspiration could be probably magnetic stands used in industry for holding dial gauges and similar things. They use shortening of the magnetic flow to virtually turn on/off the magnetic force. So if you would use servo for that or just use shortening circuit using the coil, it could work I think. It may be worth to try.🙂
I tried to find the things you're talking about. It remined me that I had found somethings like that which may suit. fr.aliexpress.com/item/32717848573.html I'll give a try. Other sources welcome. Thanks for the suggestion
@@workshopfeedback I ment to leverage this principle: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-N7tbN-LnBAQ.html It's in czech but the principle is that there are two pole extenders that are either shortening the magnetic path or extending the path. Between those two extenders is diamagnetic material - aluminium in this case. Hope it helps.
That's absolutely amazing! Also no one is perfect at making videos from the get go but you did awesome work on explaining the things, good angles and quality on the video, you have a really good start!
Hi Mathieu, It would be quite a work to to make my files shearable and there are lots of things undocumented. If you have questions about specific points, I'll try to answer.
Hi Greg, As Voron is a CoreXY Printer with three Z axis, there are similarities with Voron Trident. I inspired of all what I found of the web but as I started the design from scratch and didn’t use any of the files provided by Voron, I don’t think that you can say it’s a Voron. By the way, oldest Voron Trident files are dated August 2021 and I designed and built my printer between January and August of the same year.
@@workshopfeedback I don't think he meant that the Voron team is claiming this work, he was suggesting that the Voron adopt your design into their CoreXY system. I would love to have a tool changer capable Voron and your system looks easy to implement. Nice work!
Hello, I am consider building my own printer with toolchanger based on you great idea. Could you explain how washers on tools are flat with screws head (the part which is attracted by electromagnet)? Do you use wide washers with smaller screw (for example wide M8 washer with M4 conical screw) or do you use some special washer/huge flat magnet?
Hi, here is where I bought them : www.magnet-shop.com/adhesion-grounds-adhesive-surfaces/metallic-grounds-for-screw-mounting/2407/metal-disc-oe-34-mm-with-hole-and-countersink-nickel With a M5 conical screw
I assume that you use an electromagnet for the tool changer. You can also consider to use a switchable permanent magnet 🧲. There are several video on youtube about this. E. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-n9tZIFfM14o.html
Yes it was a solution using a servo to rotate the magnets. I love this one : ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-bYUtPNZ3ag4.html The advantage is that the head doesn't just fall down when there's a power supply failure. But with an electromagnet there's no moving part unless the spring effect which would be necessary in both designs.
Can you tell me more about the carbon fiber "rod" you are using to guide you hot end cables? I have a V-core 3 500mm size and am having a terrible time with the cable management for the hot end falling in the motion area and getting stuck or caught. Your setup looks like it would solve my issues. Where did you get them from? What is the width and thickness?
Hi, Connor I can't find where I bought them as it was a long time ago. On eBay maybe, it's the sort of thing you buy because it could be usefull one day. Mine are 0.5 mm thick and 10 mm large. Maybe not the most easyest thickness to find. Any idea somebody ?
@@workshopfeedback thanks for the info, just having the size will help me determine what to buy. I was unsure how thick they should be. To thick and they won’t bend, to thin and they might snap. Knowing they are .5mm thick is a huge help!!!
this is so amazing..... is there a secret way to get this build information 😉😉 i wont tell a soul!! i have almost everything on hand to build one of these from the looks of it. Seriously .... right when i saw the maintenance holder magnet place....i knew this was something special!!! Either way, thanks for the video and inspiration, if you need a beta or alpha tester, im your guy! cheers! from the states!
I can't be of any help about Klipper. Access to the software data structure e.g. {move.axes[0].machinePosition} is one of the wonderfull Reprap feature. If available on Klipper, porting should be easy
I love your ingenuity and the simplicity and elegance of your designs; what a fantastic job. It's people such as yourself who make this community so bl00dy awesome! 👍 I've subscribed; I'm looking forward to more updates. 😎
Hello, I like your concept of tool change with electromagnet, I'd be interested in understanding how you optimize the heat generation of the magnet, I assume that the magnet remains in electrical voltage for the entire duration of the coupling generating a nice heat source? isn't this dangerous? Are my assumptions incorrect?
Hi, thanks for your comment. The magnet consumes 6W and heats a bit because it's enclosed in the carriage. I added a 30mm fan and left a down to top air path in the carriage to avoid overheating which is sufficient.
@@workshopfeedback Yes, thank you for your kind reply, out of curiosity I asked the question before fully watching the video, in fact you mentioned it, my fault :) if I may ask what g-code command do you use to activate the magnet? i would like to come up with something like this in the project to make a home printer for me thanks.
This I would like to follow. You attack interesting challenges with exemplary good solutions and I really hope your work will be noticed and appreciated.
This is a very amazing design, clearly showing that a lot of thought went all parts of it. Though I personally would have made the filament box wider, to allow the use of bigger spools than the 1 kg kind. But anyways, a very very impressive design you created there.
@@workshopfeedback Thanks! I have very little experience with CF do you think 1mm would be too thick to bend properly in this application? Thanks for the info!
@@nerddub I think the main problem with the thickness of this part is the elasticity and the varying force it applies to the carriage depending on its position. The more flexible the better, you must feel the influence it will have on the kinematics of the printhead 🙃 Difficult to know without having it in hand but I think that going from .5 to 1 mm makes quite a difference. For the wires going to the carriage itself, as there's no bowden tube to support, I cut the strip in half lengthwise with a Dremel, it makes it softer.
It should be a good idea to place the electromagnets only on the resting point and use them to "release" the coupling somehow. Awesome, Like from Spain!
It's an idea. I'm not sure that the permanent magnet used for the coupling wouldn't be unmagnetised by the release field over the time. Greetings to Spain from France
@@workshopfeedback Forget the permanent magnets, i mean a mechanichal coupling who dettaches when electromagnet is powered with one electromagnet on each holder. If you are on a discord or something i can colaborate on designs
This is one of my favorite quality RU-vid video. You showed us what is possible with engineering design skill. You’re truly inspiring. This make me wanna design my own printer and RU-vid really got a lot of good design engineering people. 🙇♂️
I have but one question… How are you handling the fact you violate one possibly two patents that Stratus currently holds in regards to tool changers? Given that, this is a nice approach! Very nice…
Hi John, and thanks for your comment. I have to say that I don't feel like I'm violating anyone while I'm tinkering in my workshop. I'm curious to know what good idea I had that isn't the simple application of knowledge shared by everyone for a long time. Unfortunately, I don't know Stratus.
@@workshopfeedback Here is just 2 of their plethora of Patents. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-nB2AFsNMAg8.html As to what you might be violating. The minute you share it. :)
@@johnbeima6413 Hello John, Hello John, Thanks for these informations. I am not a PI engineer, but after looking at the patents mentioned, I identified several significant differences in the description of the processes compared to those used on my printer. On the other hand my lawyers, who are not IP specialists either, do not seem very worried about the claims that can be made in the context of this video. You may be an engineer or a lawyer specializing in IP, in which case I would be very interested in your opinion on either of these points.
@@workshopfeedback By the way, this is because we are looking at approaching this as well. So this is something over time we would also come up against. Hence asking, since many others feel there is no way around these.
Omg! It's sooo well thought out! I even got answers to all my questions that arrived at the beginning of the video (i.e. flexible part with a washer which could eventually brake). I believe this channel will grow exponentially
This is incredible I cant imagine how many iterations it would take me to get there, and maybe not even then. My favorite feature is the position of the steppers, if only my printer could self level. I also love how light your printhead looks without those annoying doubled up steppers.
