One note on the video: While I was editing this one, I noticed that I had originally misread one of Ryan's tweets. The video is edited to reflect that, but its tone is still a bit harsher than I'd like. All things considered, the MPCNC is not the right project for me, but I still wish Ryan all the best with it.

[@otto85521]

Absolutely right. Just look into the LEGO case. After LEGO run out of the patent rights of a brick they tried to have a copyright on the general design and failed. Everybody has the right to make their own bricks with exactly the same sizes and fit of an original LEGO brick and can sell it as much as they want. They are just not allowed to sell it as LEGO.

[@hannesgroesslinger]

Exactly. Lego only has a copyright on the design of the figures, as the design of the heads, arms, torsos, etc. is non-functional and therefore can be protected. That's why other brands like Cobi, CaDA, Xingbao, etc. have different figures or don't include figures at all. But the actual Lego bricks are purely functional parts, so Lego has no protection on those pieces since the patent ran out . Other manufacturers are allowed to produce the same type of bricks, with same design and same dimensions. (And often with the same quality, but at half the price)

[@elvishfiend]

Lego also have (or at least, had) patents on many specific methods of joining blocks together, even though they only used one. By patenting the other methods, they could block other manufacturers from using them. But that's a functional aspect, and totally different to copyright

[@elvishfiend]

It's similar to the way you can copyright code, but you have to patent the actual programmatic mechanism that it acheives

[@jvleugels]

For years I've had the feeling that 3D printing became big because of the open source mindset of all the awesome developers. And 3D milling has been stuck in the past with a mindset of doing it on their own. Also visible in the available documentation, software's and firmware.

[@MyBrothersMario]

that's a large part of it, 3d printing really started to boom after patents owned by Stratasys and to a lesser extent 3D Systems expiring.

[@cosmosity1693]

It's because CNC is reductive, and Printing is additive, these people want to reduce making, not increase it!

[@JeremyDWilliamsOfficial]

Very true. Different mindsets.

[@LuLeBe]

I see this mostly with models. Thingiverse is so big while there are no such sites for milling machines. Probably the cost plays a role as well, we all got 300€ printers, but any decent mill/router is so much more expensive. And if you don't want to diy the whole thing, prices start around 1000€. So really, I think just the machine costs, plus the noise, dust etc that make them bad for home use, reduce the number of people working with them. And that mainly leaves professionals in the space and they have to make money, so free stuff is hard to find. Yet grbl etc are awesome projects and work amazingly well.

[@danvercillo]

@@isaackvasager9957 Ryan had no problem with Tom releasing the design. The rub is that Tom wanted to release it with no license restrictions. All Ryan asked is that Tom re-release the part with a properly restrictive license so that people wouldn't try to sell it. This design was never open source and Tom knew that before he printed and built it. For Tom to release this part with no restrictions, then balk when Ryan nicely asked him to change the license is totally not Ryan's fault.

[@reneromo8814]

​@@isaackvasager9957 From what I gather it was more to do with the actual license that Tom wanted to release it under. MPCNC is released with a non-commercial license meaning it can only be sold by Ryan. From Ryans POV - Remixes/Improvements should be considered derivative and published under the same license. Tom made a new design and released it under a license that would allow for someone else to commercialize it. In other words, if Tom were to have made changes to the all of the MPCNC parts by changing each dimension by .00001mm and released them with this license then anyone would be able to Print Tom's files and sell them. Effectively undercutting Ryan's livelihood by allowing anyone to clone the MPCNC and sell it online. As far as I can tell Ryan has no issue with remixes/redesigns so long as they are under the same non-commercial license. Seems to me that Tom could've chose to make the changes he wanted and simply released under the original MPCNC license. Instead he chose to try to strongarm Ryan into making this completely open source. I appreciate Open Source projects but IMO respect to the creator comes first. In this case I see no reason why Tom couldn't have just respected Ryan's wishes and made his redesigned parts the same non-commercial license.

@@reneromo8814 that is not at all what for instance Prusa does for living. Hunting down people with other licenses. But as Thomas CLEARLY say.

Gohliat1337 Same for me. Will look for another printed cnc

[@aserta]

Don't bother. A CNC needs rigidity because of the lever arm forces + rotational forces induced by the cutting head/motor. Making one (excepting time and material costs)with 3D printed parts is like walking one step forwards, 10 steps back. Trust me. It's a waste of time elevated to nightmare shituation. That being said, you can get away with making various components out of wood/MDF/HDF and various pipe clamping options. Using printed parts isn't worth the effort because they can't assure you of the tolerances required of a CNC. At the lowest end, is wood, above it, aluminium, above that steel, and the top, cast iron (there are inbetweens like, pouring concrete inside the components to add weight (mass is important) and rigidity). As for design ethos, look up the Inventables CNC. That's the most barebones CNC design you can get, and that's a good thing because you can adapt a lot of the elements found in there to pipe and clamp design without spending too much time figuring out what should be what. One other hint, get a dial indicator. The cheapest of greater division (inches or mm, your mileage may vary) you can find on fleaBay/Aliexpress etc. You need one. From measuring the parallels, to the travel, to the table plane being level. You cannot build a CNC without such a tool. You'll also need an arm and a magnetic stand for it (also, found on the cheap on those websites).

Yes that's a good usage case for lightweight round section tube, a CNC machine definitely isn't. Round is useful for torsional loads only, not bending as you get from cutting forces, for that you want rectangular or square. This thing has the worst possible combination of design choices. Poor deflection resistance tubes that are nowhere near solidly anchored enough at the ends in torsion so as to be able to resist twisting, just a mess. It's one step removed from hot glue and drinking straws.

When I finally had an opportunity to look at your hard work the party was deemed over (by Ryan). If it is any consolation at all there are many of us that truly appreciate your work. If you gave your stamp of approval it would mean far more than anything V1 engineering could post. Please continue your efforts to make a similar device as I'm sure there are thousands of us that would benefit from your contribution.

Licenses are a mess. Props to you for pointing that out

[@goury]

Licenses are fine, but illiterate, greedy and envious people applying them to whatever are the mess. CC-NC series of licenses are meant for common "freeware" and "shareware" where you can have your demo version for free but can't do anything with it and have to pay for some different license in case you want to actually have it. But modern hipsters just throw in NC clause out of greed or envy, without thinking for a second about issues and consequences it will result in. CC, sadly, is but a malignant tumour on the opensource community which is a malignant tumour itself on the free software movement. Best we can do is to just cut it away before it's too late.

Once convinced this would work, I sat through (almost) all of Tom's videos and became excited that I could build this for a laser cutter/engraver.

Not sure why everyone supports this license when someone starts selling thingiverse parts on eBay but now Ryan is protecting a design he spent YEARS working on and this arsehole basically says he's going to modify it slightly, change the license and let anyone sell it commercially (because that's the only difference really). Getting salty about being challenged on it and making a sulky video doesn't change his intent but I'm honestly surprised at how this comment section is full of people lapping it up. Ryan isn't some corporate goliath trying to keep 3d printing or CNCing from the masses, quite the opposite! You can literally print all his parts and he won't make a dime.

I built one of these 2 or 3 years ago. Not for CNC milling, but as a platform for a laser cutter. It worked OK, but had issues then as well. I haven't considered redesigning this system, but do have ideas for an entirely different design. As CNC for a laser head, the flex associated with the tubes does not present a significant problem, but I would hesitate to put a dremel on it, much less a better spindle. My take on the whole thing is that Ryan sees the CC-0 license as incompatible with the license he chose, and Thomas sees the CC-A-NC license as incompatible with his lifestyle. Rather than have viewers pestering him for the next 10 years asking what happened to the MPCNC he built in a series, he put the video together to explain his case. It sounds to me like he is not raging about the situation, just disappointed in the situation.

I was going to be buying this kit, in fact, I finally took the plunge and ordered a CR10 (for 260$ shipped, so it was kind of a steal) because my first 3d printer was too small to print some of the parts. Now I'm not certain that my money would contribute to a community I'd be proud to support. It's unfortunate as I've finally got all of the parts printed, but thankfully it only cost me 30 bucks worth of filament, and not $400.

A couple weeks back I want to a seminar at VDE here in Germany where two guys from Open Source Ecology were talking about their projects and also explained the types of creative common licenses and all that. Found that quite interesting. But now seeing Lego threatening to sue people who create similar designs to them and this mpcnc story really gives everything a bitter taste ... I hope this trend doesn´t proceed or else this creative community won´t last long.

[@Apenco72]

I suppose that is the only decision that makes sense. A bit of a shame after this amount of work though. I built the machine 1-1/2 years ago after a complete redesign of all parts in Solidworks. The US pipe diameters are fairly useless in Europe, and the 25mm one is just too expensive to experiment with on a larger machine. Mine is based on plain galvanised German plumbing pipe, metric fasteners and a Kress router. I spent a lot of hours on the design. 3D printed chains for the cables in all directions, cable feeds through the carriages, a new Z-axis for the Kress that positions it closer to the x-y crossing. Of course I tackled the belt tension issue with real adjustable tensioners, also because when both axis have different tension, the x and y scaling differs a lot on a larger machine. Nevertheless, the result is still a rather flexible machine, like yours. To my humble opinion, it’s no good for anything but cutting styrofoam. At least on a larger scale than the original. Maybe as a 3D printer frame, but then you would have an issue getting a heated bed that size. Or promote it as a cake glazing machine perhaps? I’ll bring the beers 😀

I feel like Ryan killed his own project for a matter of licence. Who want to get involved in this if they can't modify it? Are we allow to CNC what we want with it or the GCode that it takes is also licenced therefore we can only use it with a finite collection of pre-generated GCode?

If Ryan had a patent on that part, then he would be right, but he does not.

Copyright does not protect against similar things (but patents do) and Trademarks don't protect products that don't show the trademark.

Hello Tom, I just want to share some thoughts/comments on the MPCNC and your experience with it. I'll make a bullet list to (try to) keep it short. - I build myself an MPCNC back in October 2016 and I was happy to get your notification on the live build videos. You are a mentor for a lot of people and I was sure that your video would contribute to growing up the MPCNC community. - I've built the MPCNC with almost the same dimensions as you have and I found the same issues that you have encountered like the nut traps not grabbing the nuts properly (metric hardware). I found that welding together the "lock corner" and the "bottom corner" parts improve the rigidity of the assembly a lot. - I've designed myself a derivative of a part compatible with the MPCNC and posted on Thingiverse (part 1933416) and like me, tons of makers have done the same (with various licenses). Some of them are a must, like the "Universal Mount". - Thus I was very surprised about your dispute on Twitter and very sad about the end. You spent a lot of time and for sure with your experience and expertise, everybody could have benefited.

[@SianaGearz]

What an absurd situation. Well i understand their needs as a business, that they don't want someone else selling their design. It also seems reasonable that with this approach, you're entitled to some kind of compensation for negotiating a custom license with them for allowing them to use your part commercially. So public release of your part under an NC license is an appropriate solution for you to publish your work in the interim. It might not even be a practical issue, since your part that follows existing MPCNC license can be used in all settings where original MPCNC part could be used. There's probably room for exploration what NC was meant to mean for this project or why it was chosen. I don't find it likely that it's intended that the use of parts in makerspaces or other such settings where some money changes hands is restricted, but mass resale of parts is intended to be restricted. I wonder if license modification or clarification is appropriate. I don't believe it's impossible for you to come to some sort of agreement that would make your part useful in the widest variety of contexts. Its certainly true that copyright doesn't extend to functionally compatible parts created from scratch, since function is the domain of patent, not copyright. But law does not express a lot of finer concepts very well, related to community collaboration and such, it's a guideline on what not to do, but not a guideline on what to do. And OMG twitter, did i ever mention my passionate HATRED of twitter? Whenever you try to have a nuanced conversation, the limited text length just gets in the way and leads to compressed wordings that are way too easy to get the wrong way. Thus the "harsher than intended" tone that you mention somewhere. In my opinion, when you have any sufficiently complex matter at hand, be it technical or policy-related, take it off twitter IMMEDIATELY. Everyone. Do it. Remember. Public discourse is good, and you probably can think of a forum you can move it to.

[@SpudGunTechie]

It's a good point; releasing under the NC license makes it no more restrictive than any MPCNC part, which Tom was apparently fine with when he started. I think this is just incredibly petty. If you don't want to release your part under a derivative license, I can understand that. In fact, from my point of view, Tom is reverse engineering the part, and clearly not legally making a derivative work. But going out of your way to completely disassemble the machine, too? This is absolutely petty, and I do not respect this.

[@SianaGearz]

@@SpudGunTechie I can see the logic and I don't believe the decision has been made out of mere spite. Look at it, assembled from European hardware with its diverging dimensions it turned out to be a remarkably bad machine. By all reason, it should be fully reingeneered. But if every part turns out different and doesn't contain source model data from MPCNC, why should the designer of MPCNC be allowed to take credit and dictate license terms? After all there is nothing particular about MPCNC either, all the ideas it's made from are basically 3D printing community's folklore of sorts, a selection of engineering solutions that have become commonplace and trivialised.

@@SianaGearz I can't think of another CNC or 3d printer that uses bearings rolling on electrical conduit for motion. This is a unique design. People act like this is a dispute over a single part when Tom stated his intentions to make minor changes to all the parts and re-release it as "OPCNC" with a CC0 license. Leaving Ryan unable to defend his design and maintain his livelihood.

@@hodgeac Electrical conduit is just a thicker substitute for a rod that happens to be particularly cheap in USA. There have been plenty of little 3D printers like Mendel and Huxley which ran roller bearings on thin rods. You need to build something bigger and handling higher load, you're going to need to scale up the components of the motion platform, including the rods. It appears like a completely logical evolution of existing designs. If it was genuinely unique, you'd think patent protection for the design would be available to secure it against commercial copycats. Unfortunately for Ryan, he has no rights on the design that extend beyond the specific design work performed to produce his parts. Your "single part" argument is a straw man, there has been no such claim in this thread. To me it is implicitly understood that Tom would redesign as many parts as he feels like (whether the complete part set or not), and would offer them under the license of his choosing in the course of the project. But i don't think it was necessarily planned, i think he was building it to see how it would do, and if it performed well enough as-is, that would have been it.

Thanks for sharing. Thought about making this cnc but not any longer. My opinion is that the whole idea of these kind of projects is to be able to improve and have fun with the design. I'll make my own from scratch to be sure I can do what I want with it.

[@GeoffreyPitman523]

No one is stopping anyone from doing what they want with the design, only asking that any changes be released under the non-commercial clause. Tweak and modify away, that's highly encouraged, just release under the license.

[@3Drcnc]

@@GeoffreyPitman523 Oh I didn't understand that that was the problem. Watched the video again and now I understand. Thank you for explaining.

[@michaelstone6633]

So glad this all came to be the way it did. I personally want nothing to with ryan and the mpcnc. Open source or no support! I'm sure there will be other machines worth spending money on. Love your honest opinions Tom never stop making informational videos.

[@sebamop]

It's a great excuse to turn the crappy MPCNC into a usable Root V3 CNC.

[@asdfqwertztest]

Also CC-NC.

[@comma1981]

Let's make a metric one! And by "let's" I meen that I am totally willing to help in the design. (I am a mechanical eng.)

[@BroncoPatriot]

Please don’t let this set you back. I have been following this project and RIGHT when it was about to get finalized it stopped. Ugh this is something I would like to build too but do not have to patience to figure out many of the other project flaws. Really hope you build your own for your community.

[@alanb76]

I was looking forward to the rest of this. Sorry to see it end this way. What other 3D printed CNC designs should we consider for similar use? I have collected most of the parts for this one.
