I love getting to see the irl building of course, but getting to watch CAD videos is like watching the previews for future episodes! I feel like i can see the future!
That is actually cool, I think. We have to see what @Wintergatan thinks about it. :-) (and as some other written, it should probably be designed so they are easy to remove with two fasteners/bolts/spring bolts and then swing away for easy access to the programming drum/wheel)
Martin, I believe triangles are rigid IF THEY LIE IN A PLANE, but are not if they are curved in space as you have done with your bracing. Then they will flex and may have a resonant frequency. Please check with an expert before relying on this design! I am so glad you are so open with your designs, hopefully the wisdom of crowds will keep you from the worst mistakes. Great job!
I tend to agree. I am also a bit concerned about the center of gravity. It looks like the MMX will be pretty heavy on its backside (opposite from performer). Even more so with these crossbars. The center of gravity will have to be judged in different situations: without any marbles, fully loaded at rest and fully loaded when operating, since we can deny the weight of the zillions marbles. Love the channel and I know its Wednesday when Martin's channel pops up in my new items!
"I know you have a little allergy against CAD videos" Doesn't matter Martin! I love to see everything that is involved in building the MMX, including the less interresting parts like CADing! Please continue making videos about everything involved! Keep up the amazing work!
The X around the back not only complicates programming, bit will not really add significant stiffness, because you have them bent into helical curves. Think about it this way... each of the diagonal braces is essentially One half turn of a big spring. They can, and will, oscillate with the rhythmic input of the hand crank. Welding them where they cross simply shortens them to quarter turns of a spring- the crossing point becomes the node and the frequency of oscillation simply doubles. Triangular trussing works, but only in plane. Bending it around the cylinder does the opposite of what you think it will. If you plan on removing the upper section for shipment the entire upper mechanism needs to be more rigid and less prone to "rack" if it’s to be handled separately. Underneath the marble drop mechanism you might have opportunity to conceal a shear plate crossing from left to right steel frames... or even an X brace of smaller steel square tube. You could likely place some form of shear plate across the top back of the machine, out of the way of removing programming plates, and that plate might even have the wintergatan cut out so that it forms a logo... wherever you can address the shear issue with gussets and plates, I think you will bet a more satisfactory result than worth two big steel springs across the back.
If both on the back are joined together in the middle, they'll be much more rigid than you'd think, as when diagonal loads are applied to the frame, one of the crossbraces will bow outwards, but the other will be pulled inwards, and they will constrain eachother this way
@Wintergatan 7:00 "#1F0-003 PULLEY", you misspelled and wrote "#120..." The mistake also seems to continue to the next few parts because of auto completion.
I believe the majority of your viewers are immersed in the WHOLE process of MMX. Those who are not into CAD can skip through, those who are not into CNC can do the same... there is something for everyone. For me, I have for many years been fascinated by CAD/CAM, and experimented with any software I could get my hands on! The Autodesk offer of Fusion 360 to students/hobbyists has been a gift from above. After months of diligent effort, I have reached the rank of "Bumbler, 3rd class". I can learn more from one of your CAD videos than many of the tutorials on offer. Thank you so much once again... there is nothing you should apologise for here.
M8 tapping hole is 6.8mm not 6.3 as you said . you would get away with that for nylon or delrin but in steel it will be snappy tappy time . that is unless you have some weird metric super coarse thread in mind . thought i would mention it before you make the parts . loving your stuff by the way ,Cheers Ade .
I'm not sure what you're talking about. I got one today. But it's detrimental to the channel not to run ads, UA-cam algorithm doesn't recommend the videos as much if they're not monetized.
Videos are recommended by minutes watched and quantity in a row. UA-cam has told a prominent Flat Earth channel that the reason FE videos get on the side bar is because people will binge watch 20 long videos in a row and rack up lots of watch time. This makes YT happy.
@@billkeithchannel no, he's not reading the file names, it's a continuity error. In the document you can see the file names they are supposed to have. Luckily, if someone has access to the file, they'll have access to the original, and can trace the error there, and find the part that they are looking for like that.
As someone who only learned CAD recently, I find this super interesting. Like anything else, seeing how someone uses the same tools in a different way is always fascinating and helpful.
I like watching your CAD videos a lot! As an engineer I do a lot of design in CAD and sometimes the process might take a few years before I ever see what I'm designing built. There is a balance between the design and making components work together when they're being built. When you require high-precision you need more time in design. Keep up the great work! It is very important to show all the work that goes into the Marble Machine X, because projects like this are about the journey and not just the destination.
Martin, you are a treasure. I so enjoy your episodes and look forward to the next one. When I first came across your channel, I remember thinking, “This guy is interesting in a quirky kind of way.” Over the last year or so you have grown your skill set so much. I hold you in the highest admiration. Please continue to share your progress in what ever direction it takes you. Thank you for sharing your journey with us.
Have you considered some safety overload clutch somewhere to limit torque? If your machine gets stuck for some reason, it could save your machine to break totally.
In one of his other videos, Martyn said that he was planning on having the CAD be released to the public so that others could build their own design. It would stand to reason that all he would need to do, is just to go into the CAD in a similar process, and order replacements for whatever part may have broken.
@@Bondubras In case of a maybe unlikely but possiblecatastrophic failure you don't want to reorder half your machine or even just a new programming wheel when you are on the road. This thing has to be bullet proof for a world tour.
@@NochSoEinKaddiFan Pretty sure at some stage he said he was building two complete machines for the world tour. Or at least a second complete machine worth of components
I have 4 years CAD drafting experience from a long time ago its great to watch you do this. Its part of the process we all want to know whats going on so I love the fact that you show all the steps. Keep up the great work and thanks for keeping the video sponsor free!!!
Thank you for the safety features!!! That thing was starting to look like an early Industrial Revolution factory machine that chopped off limbs from the children who labored around them 12 hours a day. I can sleep better now. :-)
Martin, your choices are so solid in every way. The design work is the core of invention. Yes, we need skills to use the tools to put things together, but the design is so much the bulk of the project. A little CAD here and there is appropriate. You are teaching us so many things.
Your talk through for me is invaluable. For anyone learning Fusion 360 you have shown a score worth of time saving functions that would have saved me hours in cad-ing. Would love to see a library of these sort of talk throughs as you go along in your modeling process. Thanks!
I can't speak for anyone else, but I love watching Fusion 360 videos. Please don't stop making them, even if you only sprinkle them between "real life" prototyping and build videos. You're definitely at a high level of proficiency in Fusion 360, thanks to the massive task that you've set out for yourself; it's really fun to watch it go from idea to design to reality.
As an someone who uses CAD (creo) everyday, it is wonderful to watch someone with a different background and thought process design something from the ground up. Thank you for taking us along on your journey.
You know, Martin, you keep saying, "I know you don't like watching me do CAD, but..." I'm just going to say that I am EXTREMELY happy that you made this video and that you walked us through many of the steps that you take in designing the MMX. I've been doing kinetic metal artwork for a while now, and I've wanted to learn CAD for at least a few things that I've designed. Your video is the first one I've seen that shows all the possibilities available in both the creative and practical sense. It is great to get to sit there with you and watch you design a part. Somehow I'll have to find some decent, cost-effective software so that I can begin experimenting with it. I think that my own ball machines would change, perhaps drastically, being able to do CAD work. Thanks again for sitting us down and allowing us to see the process. It is quite an eye-opener.
Excellent travail ! Nous sommes ravi de vous compter parmi les plus grands ingénieurs de notre pays. Votre projet inspire les muses et les satyres, j’ai hâte de voir la machine terminée. Continuez sur votre voie, vos efforts génèrent de grandes ondes positives grâce à votre passion et la musique réunie. Cela transmet un message d’espoir et de bonheur pour le présent, mais aussi pour nos générations futures. Vous pouvez être fier de vous tous ❤️❤️❤️
These kind of videos are awesome and I can not really understand how some people might be "allergic" cading content. As you said, cad is the place where all the thinking and magic happens. Everybody should be aware of the possibilities and chances this technology brings to us. Especially in the combination with cnc machining. You virtually create a part in cad and boom, it becomes reality. It's so satisfying to see your project growing. Seeing you cading is a beautiful example of how good planning and great teamwork with manufacturers can lead to this real life mashine. A peace of art from cad to assebly. Awesome job man, keep up the great work!
CAD is always welcome! I'm growing my confidence with Fusion, so seeing your fluidity with the software is inspiring! I'm looking forward to being so capable. Thank you sir.
A lot of people enjoy watching the actual machine go together, it's a lot more satisfying to physically see the parts. With that being said, the CAD portion is still fun to watch, it gives you a good view of the components that you just can't access physically, like being able to zoom and rotate from any orientation.
the diagonals around the programming wheel, that you said we won't like, don't seem be efficient, since it's the triangle structure that makes stability, so when you brake up that triangle going in different directions force finds new ways of bending etc. ..maybe that's wort being considered. since that's what construction enineers do all their lives you could easy make a little challenge. "Please make MMX rigid my friends..."
indeed, besides, there are nicer ways to stiffen this structure than using cross braces, like extended ribs on the outside, i hope he takes some time for a nice way to fix this.
I'm not upset with the cadding episode! Nor was it boring, I learned a lot about 3D modeling and cadding due to this and seeing the ideas flow is so inspiring! Can't wait to see the finished product!
Curved X-bracing will not work as good as straight ones. Elasticity vs Flexibility of the brace material. But maybe the Flexibility of the curved one will give enough resistance to achieve your goal.
You're a prince. I appreciate how humble you are and how cognizant you are that not everyone can afford to support you monthly. Keep up the great work and I can't wait to hear your machine in person one day.
This video is actually great. CADing is hard, it is even harder to CAD something so sophisticated. I really hope you would get invited to the SapceX project. And I would definitely be going to your world tour! (If it includes Hong Kong :P )
Unfortunately, SpaceX isn't allowed to hire someone unless they're a US citizen since it's a rocket technology company. And unless I'm mistaken, Martin doesn't have US citizenship.
Martin, you may think we hate the CAD videos...and sure, the building is super fun to watch.... But every time we get to see that nearly-fully-designed 3D model in a computer, we glimpse a fantastic dream of a wonderful individual. A dream that inspires us. Seeing that 3D CAD dream is what makes the assembly and building videos so much better, because then we have the innate understanding of the importance of every part that goes into this project. Love the videos, as always!! Regardless if it's CAD, milling, welding, assembly, parts lists, procrastination, instrument playing, or just hundreds of marbles spilling out across a workbench.
Good job.. I was not expecting to find this one interesting!! I liked that you just said what you were doing and weren't constantly trying to explain how to use fusion 👍
@Wintergatan Hi :) I am sure you have thought of this, but I am wondering how you will change music programming plates with the cross bracing installed?
Easy, Make two hinges on top (or bottom) fastenings of the back side X Machine logo. Then set some spring loaded plunger, wing nuts or latch clamp so the other side is easy to loosen/remove from the other side. Then you can swing the X Machine logo up (or down) for easy access to the programming drum/wheel. Here are examples of parts that can lock and be easy to release. www.amazon.com/Lock-out-Indexing-Plunger-Multiple-Lengths/dp/B00BTI1WQ8 www.amazon.com/DimcoGray-Thermoplastic-Wingnut-Female-Insert/dp/B0015HQ5D8 www.amazon.com/Phansthy-550lbs-Capacity-Action-Holding/dp/B0721P9T3B
Honestly, watching the cadding process is pretty incredible. It's amazing to see how far you've come in how you use Fusion 360 and how you've optimized your process. It's kinda like watching Michelangelo talk about how he hits the stone to get the perfect stroke (alright... that was a little fantastic... but you take my point!)
CAD Video are nice :D. 360 is a powerful tool. Surprise that you can open the whole machine file with so much components. The fly wheels in red actually sounds like good for safety too.
There's a video about when Martin reached some kind of internal limit in the software. He had to change the way he uses the application in order to continue.
The "limit" is that moving extremly complicaticated components is slow. The way to overcome this is to make subassemblies with the same origin point. (meaning that when you are designing something that goes on top of the machine, you actually design it far away above the origin point. When you insert all parts into one design, you don't have to move anything).
Hi Martin, (And any other viewers) I personally didn't like the CAD videos as much, (in the past) With this new editing style, i think i might prefer them more now. Being able to see you make these decisions is great, and (as an inspiring engineer) I am learning a lot about the designing stage. Plus being able to straight up see your progress, its quite satisfying. If you have time, this would be my suggestion. If you need to make something, then make it and record it for the Wednesday video, Then on a different day, you upload a more CAD based video about designing that piece (or any other), that way we get the best of both worlds. I know its more work on you, but i feel that there was some internal conflict about producing more content, that not everyone likes. In the end, i think this quote can help you either way: "If you cant make it perfect, make it adjustable" Allow yourself to be flexible and make different types of content. I don't think anyone would be against you uploading longer videos, which would allow you to include some of the CAD. That's just my thoughts, do whatever works best for you!
The curved cross bracing around the programming wheel is totally going to make it impossible to change the plates without taking the bracing off - on stage? There's a ton of stuff bridging the wheel for the marble mechanisms. Why not rigidize those components for added stability to preserve your aesthetic and access to the programming plates?
Aircraft mechanic here. I know a lot about long time wear on parts. The threads and the end of the countersinking on the screw are sources of cracks and a shear failure. If the transfer of force is just the countersink and the edge of the bracket it could shear pretty easily in a short period of time. The better solution is an unthreaded shank surface and a screw that’s can take a large enough shear or side load to hold the load. Anyway, love your work and can’t wait to hear some music out of the X!
Just make them be able to swing up when the plates are needed to be changed. And easy change which only needs two spring lock plunges, self lock toggle clamp (or something else to lock the X Machine logo) and then two hinges on the other side. No biggie, except if you forget to think about that. :-)
Yes, but is it easy to replace the pin plates on the MMX drum? It should be able to be done in a consert, no place for any failure because of human errors.
Yes. Martin mentioned several times that changing the programming plates during the concert is part of the design so the machine will be able to play several different songs without needing to re-pin every time.
Never apologize for the Fusion 360 videos!! I think its really helpful and generous of you to share your workflow, the things you've discovered, and even your mistakes! Keep those Fusion vids coming!
You know you are early when there is no comment from the "It is wednesday my dudes" -guy that name I forgot :D Edit: "DMadHacks" Gotta try to remember it :D You never know when you're going to need it next time!
I absolutely love your CAD videos, man. As an aircraft design student myself I always understood that all other videos are simply the assembly and the real work is done with calculations and CADing. Also its a great learning experience since you share different tips and tricks you've learned by using Fusion so I'd say these videos are some of the most valuable ones)
I have really enjoyed seeing all different aspects of this project. This is hands-down one of my most favorite build series on UA-cam! Thank you, Martin!
They can be bolted in place, which I think he said something about. And then it can be loosen and removed or make it possible to swing them out of the way on a hinge.
This video was strangely soothing... Thoroughly enjoyed it! Glad to be part of the CAD-ing journey. I've said this before, one of the reasons I love your videos is that you share every step of your process honestly. CAD-ing is a big part of the process, so thank you for sharing.
But you could Cad in Blender too. There are extensions to make STL files for 3D printing from Blender. Blender can do lots of things, like model 3D, render, games, post process videos, etc etc. But yes, a pure cad program are probably more suited for the task. :-)
As someone with a degree in drafting, I really enjoy watching the CAD videos. I never got to use fusion360, but I wish that I had because it looks really awesome.
As a Gamedev and Blender user, I'm really jealous of the non-destructive workflow Fusion 360 has to offer. Especially linking angles, length together and having all those dependencies between every part looks like such a huge time-saver when iterating through the design :O
Wow! I'm just blown away by the intricate-ness of what you know how to do. My 13 and 15-year-olds are watching with me and I think they want to grow up to be engineers now!
Amazing Video :DI really admire you for your decision to turn down these sponsorship-offers. But I also think you should accept them at some point, for your own future sake, . I´m sure your audience would understand it. Your Videos are my highlight off the week.Keep it up :)(I will immediatly preorder tickets for your world tour as soon as they´re aviable)
Well, accepting company sponsors WILL constraint what you can do. You HAVE to make decisions based on what the sponsors what you to do. And they probably want him to build the X Machine with their tools/parts/whatever. It isn't "free" money, it comes with constraints on your work and thus your design decisions. But that said, as you wrote. It is up to Martin to choose what he wants, what he think is worth to loose, as long as he actually can afford that. I will go with whatever he chooses, but I prefers no company sponsor.
Sponsors, as he said in the video, would destroy the core of what these videos are about. It's about an open source community powered only by it's viewers. I highly doubt he's going to be hurting for money, I bet his Patreon account is going to explode. Not to mention the earnings he will get from his band once he goes on tour... I doubt most people who watch these videos would welcome a sponsorship at all. It would have greatly disappointed me, I can tell you that. I already had a lot of respect for Martin, but now that respect has ballooned exponentially for his decision to turn down sponsors.
This timeline purity policy in F360 seems way too tedious for me. :o I find it very limiting, when I can't move freely inside my design. The extremal case would be Autocad, which even remembers camera movements as design actions. :P
it's only a problem because he has thousands of parts and when he has 2 or 3 uneccesary move commands or sketches in each individual part that gets multiplied to 4000 unnecessary details in his full assembly, he covered this in an older video. Basically if instead of using all these shortcuts he took 2 timeline features to do the same thing, he runs out of performance, the program becomes unusable because it wasn't designed to have assemblies with thousands of parts in it. He knows that Inventor would be a better solution but is so invested into fusion that he doesn't want to change platforms. especially in the middle of a project.
I love your mentality about the sponsorships. "I don't need it, I'll be fine without it". Too many people are so concerned with making all the money that it ends up harming society as a whole, whereas you only seek to make enough to have a comfortable living and improving the world around you. Mad respect, Martin.
13:50 Google = how to create rust on metal in 10 minutes You can then for example clear coat the rust to keep it 'preserved'. Hope my 2 cents help for something. PS: Love all the MMX videos, it's my new weekly habit, as a person whom learns and works in cad myself I always love these.
Thanks Martin! Like many others, I also enjoy the cad portion of this project. Thanks for the pro tip on copy/pasta to get a "fresh start" for positioning an imported component!
FWIW I tend to put holes in based on a point on a sketch and a "Hole" feature. It just makes it that bit easier to change the hole size/thread when the hole is a feature. I also use "hole" for countersunk holes, rather than the chamfer tool.
Dunno if this is related, but he has done a video on how MMX is pushing the boundaries of fusion 360. Might be that keeping the amount of sketches and features down helps performance.
IS THIS what you do when you wake up? When I wake up I barely remember what my name is! This is the demonstration that you come from another planet, and that your DNA is definitely advanced !!! Seriously, you always manage to amaze!
Love the video, Martin! My only CAD experience is with Inventor, so I had a bit of trouble keeping up, but I think I understood most of it. Why is it that, when you do parametric design, you use numerical lengths rather than a global variable length? (for example, you know a bearing is x mm wide, so you set up a variable named BEARING LENGTH that equals x mm and plug that in every time you want a bearing) Is that not a feature in Fusion 360, or is it just not worth it when you already have the length memorized?
But you can do the same thing with constraints on things, which also will make it parametric design. If you change one thing, all constraints will make the other parts follow to fit too, as he showed here. (Or have I missed something with variables which constraints can't do?) That is just two ways of doing that. But yes, I do believe you also can have variables in constraints too in Fusion 360. Never done any serious work in Fusion 360 nor in Inventor.
I like CAD, but I disagree with the programming wheel bracing. Sure it's ok for the legs as it's necessary, but this is just something else that's gonna have to be dismantled and it really has no form or function, and I feel you're just making more work for yourself... not only in design and development, but also on tour. It's extraneous and should be deleted, that's my first thought
I really liked the cad video! Made me really appreciate how much work those programmers do to make CAD a thing. As a programmer, I do not want to imagine how they managed to get all that stuff to work so perfectly.
I really like the cross-braces. They form an X... It's like they're the 'logo' for the MMX. Fits well. Also, I loved this video. The CAD side was a side we only ever saw in its completion, but seeing how your brain figures out making these shapes was very enjoyable!
i actually enjoyed the cadding a lot! My wednesday is complete.
Me too
YES! Wednesday = completed!
I love getting to see the irl building of course, but getting to watch CAD videos is like watching the previews for future episodes! I feel like i can see the future!
I could have in fact enjoyed more of the CAD part! Adding on screen key presses could help (:
its all fun and games until the program throws an error at you.
18:30 NOW THIS IS THE "X" in the Marble Machine X!!! :D This fits perfect, Martin!
i didnt think about that!!!!! Nice!
Yes! Immediately thought this. GG.
If there are cross braces behind the programming wheel, how are the lab coat technicians supposed to change the programming plates?
From the front, take off a plate and rotate the wheel to get access to the next one.
But he put spider web on the front as well.
@@jjk-9 but there are braces on the front too. so now what?
The front is blocked by the whole marble release mechanism.
The first thing I thought as well
You're really staying true to your values, Martin. I admire that so much, and I'm moved by the sentiment. Gotta support this via patron, now!
True respect to him
You do realize, that the spacy spiderwebs do form an X on the Marble Machine X? ;-)
That is actually cool, I think. We have to see what @Wintergatan thinks about it. :-)
(and as some other written, it should probably be designed so they are easy to remove with two fasteners/bolts/spring bolts and then swing away for easy access to the programming drum/wheel)
Hahaha yeah! @Wintergatan the Machine is finally baptized with its X name!
I was going to say that. It's a nice hat tip, but not a main feature. Almost like an easter egg.
Martin, I believe triangles are rigid IF THEY LIE IN A PLANE, but are not if they are curved in space as you have done with your bracing. Then they will flex and may have a resonant frequency. Please check with an expert before relying on this design! I am so glad you are so open with your designs, hopefully the wisdom of crowds will keep you from the worst mistakes. Great job!
I tend to agree. I am also a bit concerned about the center of gravity. It looks like the MMX will be pretty heavy on its backside (opposite from performer). Even more so with these crossbars. The center of gravity will have to be judged in different situations: without any marbles, fully loaded at rest and fully loaded when operating, since we can deny the weight of the zillions marbles.

What Cad is the best part! anyone can put a machine together given the PBS and the drawings.
And that's a healthy attitude. Some of us really like the CAD.
I find the CAD videos to be as important as all the regular videos, because this way we don’t just see parts appearing straight out of nowhere
The X around the back not only complicates programming, bit will not really add significant stiffness, because you have them bent into helical curves. Think about it this way... each of the diagonal braces is essentially One half turn of a big spring. They can, and will, oscillate with the rhythmic input of the hand crank. Welding them where they cross simply shortens them to quarter turns of a spring- the crossing point becomes the node and the frequency of oscillation simply doubles. Triangular trussing works, but only in plane. Bending it around the cylinder does the opposite of what you think it will. If you plan on removing the upper section for shipment the entire upper mechanism needs to be more rigid and less prone to "rack" if it’s to be handled separately. Underneath the marble drop mechanism you might have opportunity to conceal a shear plate crossing from left to right steel frames... or even an X brace of smaller steel square tube. You could likely place some form of shear plate across the top back of the machine, out of the way of removing programming plates, and that plate might even have the wintergatan cut out so that it forms a logo... wherever you can address the shear issue with gussets and plates, I think you will bet a more satisfactory result than worth two big steel springs across the back.
No worries, we'll just make them out of giant micrometer c-frames, and any fule kno that those don't flex at all... :)))
Of course straight braces would be better, but you have to work with the space you have.
They could be covered in a soft foam or fleese to dampen vibration.
If both on the back are joined together in the middle, they'll be much more rigid than you'd think, as when diagonal loads are applied to the frame, one of the crossbraces will bow outwards, but the other will be pulled inwards, and they will constrain eachother this way
@Wintergatan 7:00 "#1F0-003 PULLEY", you misspelled and wrote "#120..." The mistake also seems to continue to the next few parts because of auto completion.

What is M8 if not metric? You are right though, core hole diameter is nominal diameter minus pitch. And M8 has pitch 1.25mm

It is very important to show all the work that goes into the Marble Machine X, because projects like this are about the journey and not just the destination.
Martin, you are a treasure. I so enjoy your episodes and look forward to the next one. When I first came across your channel, I remember thinking, “This guy is interesting in a quirky kind of way.” Over the last year or so you have grown your skill set so much. I hold you in the highest admiration. Please continue to share your progress in what ever direction it takes you. Thank you for sharing your journey with us.
Have you considered some safety overload clutch somewhere to limit torque? If your machine gets stuck for some reason, it could save your machine to break totally.
I think he's aiming to make each and every part expendable, so in the event I breaks, it's not as big a deal as if the original broke
The flywheel is already belt driven, which is a clutch in effect, and that's probably the heaviest rotating part.
In one of his other videos, Martyn said that he was planning on having the CAD be released to the public so that others could build their own design. It would stand to reason that all he would need to do, is just to go into the CAD in a similar process, and order replacements for whatever part may have broken.
@@Bondubras In case of a maybe unlikely but possiblecatastrophic failure you don't want to reorder half your machine or even just a new programming wheel when you are on the road. This thing has to be bullet proof for a world tour.
@@NochSoEinKaddiFan Pretty sure at some stage he said he was building two complete machines for the world tour. Or at least a second complete machine worth of components
I have 4 years CAD drafting experience from a long time ago its great to watch you do this. Its part of the process we all want to know whats going on so I love the fact that you show all the steps.
Keep up the great work and thanks for keeping the video sponsor free!!!
Thank you for the safety features!!! That thing was starting to look like an early Industrial Revolution factory machine that chopped off limbs from the children who labored around them 12 hours a day. I can sleep better now. :-)
Add chains, cages, and suicide nets and you have modern China factories.
Martin, your choices are so solid in every way. The design work is the core of invention. Yes, we need skills to use the tools to put things together, but the design is so much the bulk of the project. A little CAD here and there is appropriate. You are teaching us so many things.
When you designed the shaft, you used 6.3mm for the hole to tap m8 threads, but I'm pretty sure 6.8mm is the tap size for m8.
Your talk through for me is invaluable. For anyone learning Fusion 360 you have shown a score worth of time saving functions that would have saved me hours in cad-ing. Would love to see a library of these sort of talk throughs as you go along in your modeling process. Thanks!
It is Wednesday my dudes...
DMadHacks, now it is!

Beat to it again!
my dude! wednesday it is!
I'm going to miss this meme when MMX is done.
I can't speak for anyone else, but I love watching Fusion 360 videos. Please don't stop making them, even if you only sprinkle them between "real life" prototyping and build videos. You're definitely at a high level of proficiency in Fusion 360, thanks to the massive task that you've set out for yourself; it's really fun to watch it go from idea to design to reality.
I love you and your dedication to this channel. I love how you appreciate your connection to us, the audience. Thanks for everything you do.
As an someone who uses CAD (creo) everyday, it is wonderful to watch someone with a different background and thought process design something from the ground up. Thank you for taking us along on your journey.
The engineering is strong with this one.
You know, Martin, you keep saying, "I know you don't like watching me do CAD, but..." I'm just going to say that I am EXTREMELY happy that you made this video and that you walked us through many of the steps that you take in designing the MMX. I've been doing kinetic metal artwork for a while now, and I've wanted to learn CAD for at least a few things that I've designed. Your video is the first one I've seen that shows all the possibilities available in both the creative and practical sense. It is great to get to sit there with you and watch you design a part. Somehow I'll have to find some decent, cost-effective software so that I can begin experimenting with it. I think that my own ball machines would change, perhaps drastically, being able to do CAD work. Thanks again for sitting us down and allowing us to see the process. It is quite an eye-opener.

Martin is such a good hearted, humble, GENIUS fellow. THANK you for your gift to the world.
wont the bars make it harder to change programming pins
These kind of videos are awesome and I can not really understand how some people might be "allergic" cading content. As you said, cad is the place where all the thinking and magic happens. Everybody should be aware of the possibilities and chances this technology brings to us. Especially in the combination with cnc machining. You virtually create a part in cad and boom, it becomes reality.
It's so satisfying to see your project growing. Seeing you cading is a beautiful example of how good planning and great teamwork with manufacturers can lead to this real life mashine.
A peace of art from cad to assebly. Awesome job man, keep up the great work!
It was all fine until 7:02 where he names the component wrong
#1F0-003?
More like #120-003!
That hurt to watch!
@14:42 You can see he fixed it at some point.
@@billkeithchannel Nope, that's his spreadsheet. The cad design still has the wrong numbers (14:48). @Wintergatan I hope you fix your IDs!
CAD is always welcome! I'm growing my confidence with Fusion, so seeing your fluidity with the software is inspiring! I'm looking forward to being so capable. Thank you sir.
Why would't anyone like CAD? It's so interesting and useful!
P.S.
Greetings from the Netherlands!
A lot of people enjoy watching the actual machine go together, it's a lot more satisfying to physically see the parts. With that being said, the CAD portion is still fun to watch, it gives you a good view of the components that you just can't access physically, like being able to zoom and rotate from any orientation.
This is the best demonstration of basic workflow patterning in fusion360 I have seen, paws down, on youtube. SO AWESOME.
the diagonals around the programming wheel, that you said we won't like, don't seem be efficient, since it's the triangle structure that makes stability, so when you brake up that triangle going in different directions force finds new ways of bending etc. ..maybe that's wort being considered. since that's what construction enineers do all their lives you could easy make a little challenge. "Please make MMX rigid my friends..."
indeed, besides, there are nicer ways to stiffen this structure than using cross braces, like extended ribs on the outside, i hope he takes some time for a nice way to fix this.
I'm not upset with the cadding episode! Nor was it boring, I learned a lot about 3D modeling and cadding due to this and seeing the ideas flow is so inspiring! Can't wait to see the finished product!
Curved X-bracing will not work as good as straight ones. Elasticity vs Flexibility of the brace material. But maybe the Flexibility of the curved one will give enough resistance to achieve your goal.
indeed, there are nicer ways to stiffen this structure than using cross braces as well, like extended ribs on the outside for example.
You're a prince. I appreciate how humble you are and how cognizant you are that not everyone can afford to support you monthly. Keep up the great work and I can't wait to hear your machine in person one day.
This video is actually great. CADing is hard, it is even harder to CAD something so sophisticated.
I really hope you would get invited to the SapceX project. And I would definitely be going to your world tour! (If it includes Hong Kong :P )
Unfortunately, SpaceX isn't allowed to hire someone unless they're a US citizen since it's a rocket technology company. And unless I'm mistaken, Martin doesn't have US citizenship.
Martin, you may think we hate the CAD videos...and sure, the building is super fun to watch....
But every time we get to see that nearly-fully-designed 3D model in a computer, we glimpse a fantastic dream of a wonderful individual. A dream that inspires us. Seeing that 3D CAD dream is what makes the assembly and building videos so much better, because then we have the innate understanding of the importance of every part that goes into this project.
Love the videos, as always!! Regardless if it's CAD, milling, welding, assembly, parts lists, procrastination, instrument playing, or just hundreds of marbles spilling out across a workbench.
Good job.. I was not expecting to find this one interesting!!
I liked that you just said what you were doing and weren't constantly trying to explain how to use fusion 👍
I admire your mindset and determination during this project. Thanks a bunch for sharing Martin!
@Wintergatan Hi :) I am sure you have thought of this, but I am wondering how you will change music programming plates with the cross bracing installed?
Definitely something to take into consideration
Easy,
Make two hinges on top (or bottom) fastenings of the back side X Machine logo. Then set some spring loaded plunger, wing nuts or latch clamp so the other side is easy to loosen/remove from the other side. Then you can swing the X Machine logo up (or down) for easy access to the programming drum/wheel.
Here are examples of parts that can lock and be easy to release.

Honestly, watching the cadding process is pretty incredible. It's amazing to see how far you've come in how you use Fusion 360 and how you've optimized your process. It's kinda like watching Michelangelo talk about how he hits the stone to get the perfect stroke (alright... that was a little fantastic... but you take my point!)
CAD Video are nice :D. 360 is a powerful tool. Surprise that you can open the whole machine file with so much components. The fly wheels in red actually sounds like good for safety too.
There's a video about when Martin reached some kind of internal limit in the software. He had to change the way he uses the application in order to continue.
The "limit" is that moving extremly complicaticated components is slow. The way to overcome this is to make subassemblies with the same origin point. (meaning that when you are designing something that goes on top of the machine, you actually design it far away above the origin point. When you insert all parts into one design, you don't have to move anything).
There is nothing to say against watching you designing in CAD. And I really appreciate what you say at 21:00 about avoiding ads. This is cool. Thanks.
Hi Martin, (And any other viewers)
I personally didn't like the CAD videos as much, (in the past)
With this new editing style, i think i might prefer them more now.
Being able to see you make these decisions is great, and (as an inspiring engineer) I am learning a lot about the designing stage.
Plus being able to straight up see your progress, its quite satisfying.
If you have time, this would be my suggestion.
If you need to make something, then make it and record it for the Wednesday video,
Then on a different day, you upload a more CAD based video about designing that piece (or any other), that way we get the best of both worlds.
I know its more work on you, but i feel that there was some internal conflict about producing more content, that not everyone likes.
In the end, i think this quote can help you either way:
"If you cant make it perfect, make it adjustable"
Allow yourself to be flexible and make different types of content.
I don't think anyone would be against you uploading longer videos, which would allow you to include some of the CAD.
That's just my thoughts, do whatever works best for you!
As a beginner at Fusion360, I love watching along with your CADing.
The curved cross bracing around the programming wheel is totally going to make it impossible to change the plates without taking the bracing off - on stage? There's a ton of stuff bridging the wheel for the marble mechanisms. Why not rigidize those components for added stability to preserve your aesthetic and access to the programming plates?
If you think about it though only one set likely the rear would need to be removed. I doubt he will weld them.
but there wont be an X anymore if he removes it ;(
Aircraft mechanic here. I know a lot about long time wear on parts. The threads and the end of the countersinking on the screw are sources of cracks and a shear failure. If the transfer of force is just the countersink and the edge of the bracket it could shear pretty easily in a short period of time. The better solution is an unthreaded shank surface and a screw that’s can take a large enough shear or side load to hold the load. Anyway, love your work and can’t wait to hear some music out of the X!
Cadding is so neat!
You keep saying we hate the CADding, but I find it fascinating and humbling. You have mad skills.
Does the cross-bracing block changing the programming plates?
My thought as well!
Just make them be able to swing up when the plates are needed to be changed. And easy change which only needs two spring lock plunges, self lock toggle clamp (or something else to lock the X Machine logo) and then two hinges on the other side. No biggie, except if you forget to think about that. :-)
Really they should be able to move considering they are designing it to be able to be packed up
Yes, but is it easy to replace the pin plates on the MMX drum? It should be able to be done in a consert, no place for any failure because of human errors.
Yes. Martin mentioned several times that changing the programming plates during the concert is part of the design so the machine will be able to play several different songs without needing to re-pin every time.
Never apologize for the Fusion 360 videos!! I think its really helpful and generous of you to share your workflow, the things you've discovered, and even your mistakes! Keep those Fusion vids coming!
You know you are early when there is no comment from the "It is wednesday my dudes" -guy that name I forgot :D
Edit: "DMadHacks" Gotta try to remember it :D You never know when you're going to need it next time!
Fabian Mäkilä, I’m afraid you were just a tiny little minute too late with your comment... 🤔
So you are boldy proclaiming that are were early, huh?
(Sorry, I could not resist)
Yeah, I guess so :D I'm a slow writer when I'm watching the video at the same time :D haha
Nether could I! :D I usually don't like these types of comments but couldn't resist writing one myself as this channel is something special
Just wow! The way CAD makes the whole design process ordered and broken down into small things!
I loved watching this video. Very calm. Very interesting. Remembered me how bad I am at CAD, I make pretty much no use of the timeline :D
I absolutely love your CAD videos, man. As an aircraft design student myself I always understood that all other videos are simply the assembly and the real work is done with calculations and CADing. Also its a great learning experience since you share different tips and tricks you've learned by using Fusion so I'd say these videos are some of the most valuable ones)
Wohoo! Wintergatan Wednesday!!! 😎😁👍🎶
I have really enjoyed seeing all different aspects of this project. This is hands-down one of my most favorite build series on UA-cam! Thank you, Martin!
After those drum braces are welded into place, will you be able to remove/insert the programming drum?
They can be bolted in place, which I think he said something about. And then it can be loosen and removed or make it possible to swing them out of the way on a hinge.
This video was strangely soothing... Thoroughly enjoyed it!
Glad to be part of the CAD-ing journey. I've said this before, one of the reasons I love your videos is that you share every step of your process honestly. CAD-ing is a big part of the process, so thank you for sharing.
CAD tricks, fun reminds me of working with blender also the braces help make it more steampunkish
Even though Blender isn't a real "CAD" software. :D
But you could Cad in Blender too. There are extensions to make STL files for 3D printing from Blender. Blender can do lots of things, like model 3D, render, games, post process videos, etc etc.
But yes, a pure cad program are probably more suited for the task. :-)
I am amazed with how your brain works - perfect balance between logical and stuctured to artistical and creative!
Thank you for not doing comercial on WW, I can´t pay but hell yeah I gonna pay for concerts and the album
As someone with a degree in drafting, I really enjoy watching the CAD videos. I never got to use fusion360, but I wish that I had because it looks really awesome.
I love this type of video #morecadvideos
As a Gamedev and Blender user, I'm really jealous of the non-destructive workflow Fusion 360 has to offer. Especially linking angles, length together and having all those dependencies between every part looks like such a huge time-saver when iterating through the design :O
Les vidéos comme ca c'est bien aussi 😉
Continue comme ca c'est génial. .. j'espère que tu comprends le français... ☺
He lives in france now. So most likely
Wow! I'm just blown away by the intricate-ness of what you know how to do. My 13 and 15-year-olds are watching with me and I think they want to grow up to be engineers now!
Amazing Video :DI really admire you for your decision to turn down these sponsorship-offers. But I also think you should accept them at some point, for your own future sake, . I´m sure your audience would understand it. Your Videos are my highlight off the week.Keep it up :)(I will immediatly preorder tickets for your world tour as soon as they´re aviable)
Well, accepting company sponsors WILL constraint what you can do. You HAVE to make decisions based on what the sponsors what you to do.
And they probably want him to build the X Machine with their tools/parts/whatever. It isn't "free" money, it comes with constraints on your work and thus your design decisions.
But that said, as you wrote. It is up to Martin to choose what he wants, what he think is worth to loose, as long as he actually can afford that. I will go with whatever he chooses, but I prefers no company sponsor.
Sponsors, as he said in the video, would destroy the core of what these videos are about. It's about an open source community powered only by it's viewers. I highly doubt he's going to be hurting for money, I bet his Patreon account is going to explode. Not to mention the earnings he will get from his band once he goes on tour...
I doubt most people who watch these videos would welcome a sponsorship at all. It would have greatly disappointed me, I can tell you that. I already had a lot of respect for Martin, but now that respect has ballooned exponentially for his decision to turn down sponsors.
That was amazing. We'd totally love to see more CAD videos and please nerd out on the details. Those who are bored can skip forward.
This timeline purity policy in F360 seems way too tedious for me. :o I find it very limiting, when I can't move freely inside my design. The extremal case would be Autocad, which even remembers camera movements as design actions. :P
it's only a problem because he has thousands of parts and when he has 2 or 3 uneccesary move commands or sketches in each individual part that gets multiplied to 4000 unnecessary details in his full assembly, he covered this in an older video. Basically if instead of using all these shortcuts he took 2 timeline features to do the same thing, he runs out of performance, the program becomes unusable because it wasn't designed to have assemblies with thousands of parts in it. He knows that Inventor would be a better solution but is so invested into fusion that he doesn't want to change platforms. especially in the middle of a project.
Super interesting to see your workflow, Martin! And don't expect all of your viewers to shun CAD - some of us love it!
Adam at Abom will be really pleased.
I actually had a CAD class in high school. We used solid works. It helped me get into manual 3D modeling and general design and craftsmanship.
After the MMX is finished, I would love to create working drawings in full scale of each and every part on the machine.
I love your mentality about the sponsorships. "I don't need it, I'll be fine without it". Too many people are so concerned with making all the money that it ends up harming society as a whole, whereas you only seek to make enough to have a comfortable living and improving the world around you. Mad respect, Martin.
13:50 Google = how to create rust on metal in 10 minutes You can then for example clear coat the rust to keep it 'preserved'. Hope my 2 cents help for something. PS: Love all the MMX videos, it's my new weekly habit, as a person whom learns and works in cad myself I always love these.
Post this on the MMX reddit so Martin will see it.

Thanks Martin! Like many others, I also enjoy the cad portion of this project. Thanks for the pro tip on copy/pasta to get a "fresh start" for positioning an imported component!
FWIW I tend to put holes in based on a point on a sketch and a "Hole" feature. It just makes it that bit easier to change the hole size/thread when the hole is a feature. I also use "hole" for countersunk holes, rather than the chamfer tool.
Dunno if this is related, but he has done a video on how MMX is pushing the boundaries of fusion 360. Might be that keeping the amount of sketches and features down helps performance.
Thank you for saying no Martin! This is my refuge from work every Wednesday, I really enjoy the calm and cool music along with the design. :)
Been waiting for this all week.
IS THIS what you do when you wake up? When I wake up I barely remember what my name is! This is the demonstration that you come from another planet, and that your DNA is definitely advanced !!! Seriously, you always manage to amaze!
Love the video, Martin! My only CAD experience is with Inventor, so I had a bit of trouble keeping up, but I think I understood most of it. Why is it that, when you do parametric design, you use numerical lengths rather than a global variable length? (for example, you know a bearing is x mm wide, so you set up a variable named BEARING LENGTH that equals x mm and plug that in every time you want a bearing) Is that not a feature in Fusion 360, or is it just not worth it when you already have the length memorized?
I had this thought too. Global variables for re-used lengths would stop a lot of potential human error.
But you can do the same thing with constraints on things, which also will make it parametric design. If you change one thing, all constraints will make the other parts follow to fit too, as he showed here. (Or have I missed something with variables which constraints can't do?)
That is just two ways of doing that. But yes, I do believe you also can have variables in constraints too in Fusion 360. Never done any serious work in Fusion 360 nor in Inventor.
I personally use fusion 360 a lot, and I love learning the extra little tidbits that come from watching your cad videos!
I like CAD, but I disagree with the programming wheel bracing. Sure it's ok for the legs as it's necessary, but this is just something else that's gonna have to be dismantled and it really has no form or function, and I feel you're just making more work for yourself... not only in design and development, but also on tour. It's extraneous and should be deleted, that's my first thought
I really liked the cad video! Made me really appreciate how much work those programmers do to make CAD a thing. As a programmer, I do not want to imagine how they managed to get all that stuff to work so perfectly.
I dont like cading, I LOVE IT :D
I think I'm going to check for Fusion 360 lessons after this video :-)
@@giovanniconconi1228 I like inventor the more, but I like all kinds of 3d design programs
props for keeping this personal and not getting corporate sponsors, martin. i appreciate it, you and your work, from the detektivbyran days and beyond
Wow I almost can't understand what you're doing, looks very interesting though, I even learn something
I really like the cross-braces. They form an X... It's like they're the 'logo' for the MMX. Fits well. Also, I loved this video. The CAD side was a side we only ever saw in its completion, but seeing how your brain figures out making these shapes was very enjoyable!
