After using the Tiny CNC that I made back in January for a while I've been wanting to improve it and make it more rigid. The natural next step for that router would have been to machine the plastic parts in aluminium but I was sure that the rods and bearings were way more important in terms of rigidity so I set myself to redesign it using linear rails. In the end I started the design from scratch and every single 3D printed part in it is new. I've tried to keep it as compatible as possible with the hardware of the MKI just in case those who got the files for it can switch to this new design.
In this new version there's also more clearance for stock, up to 85 mm and more usable Z travel as it can move up to 60 mm. The vacuum hose adapter of the MKI was taking a lot of usable stock clearance so I've designed a new retractable one that mounts on the side.
This one is clearly more rigid and can be pushed a lot to machine faster and better parts and I'm pretty happy with the final design.
As always I'd love to read your thoughts down below. Enjoy and thanks!!

What I really like about this build (and most of your other builds) is that you manage to build something incredible with very few different components, and a few tools.

[@ivanmirandawastaken]

💪💪

[@XTJ7]

That's what differentiates an average engineer from a great one. Clever engineering makes the most of the fewest parts. He almost makes it look easy because the 3D printed parts are well designed and keep in mind a lot of different requirements (ease of assembly, cable management, spaces for the vacuum attachment etc.)

2 things. I appreciate how long it takes to edit the scenes where you hyperlapse the whole punch or drilling (edit time >>>> produced edit) I love the confidence you have in your designs that you put 100% into their builds only for them to work great

[@VincentGroenewold]

What a wonderful idea to share the design and show how to built it! When I'm settled I'm very likely going to first built a printer and then this. :)

[@blahorgaslisk7763]

I often feel the pull from projects like this, and I'm pretty sure I could pull it off. But then I realize that if I made some thing like this all I'd end up with is another machine I wouldn't know how to use. Or rather I'd know how to use it but wouldn't have anything to use it for other than building other projects like this. Thing is I have zero creativity, so all I can do is follow instructions. Even the smallest modification would end up looking like crap as once I made something that worked as intended I'd stop there. As for making something new, designing something myself, fugget about it! I'm not kidding. I have no creativity what so ever. It was the same when I learned to program. I could optimize code, clean up code, rewrite code but I totally sucked at writing a program from scratch. But polishing up someone else's code? That I was darned good at! Now there's money to be made doing that. It's not flashy but someone who can take a ugly yarn of undocumented spaghetti code and turn it into well documented, structured and optimized code will always have a job. But I wanted to write my own programs, only lacking creativity I simply couldn't, so I bailed on being a programmer. It's the same with things like this. I'm competent with tools, but I suck at making anything new. I might make something that kind of almost works, but it will look awful and probably snip your fingers off if you look at it wrong, and even that is a big maybe... So I have held off on making or getting a 3D printer as I know it would only collect dust once I'd printed a Benchy.

[@bareabarea3449]

[@giantman261]

I think this is the most capable printed cnc I have seen. I like the idea that machining aluminium replacement parts for its self is possible with it.

[@ivanmirandawastaken]

It definitely is

[@teitgenengineering]

The way you have the belts stationary and the motors moving is very interesting

[@tomnorman5461]

Unbelievable 3D modeling skills...your desktop CNC is a work of art sir! Would love to have one in my shop!

[@TheExplosiveGuy]

This is awesome! One tip for getting cleaner surface finishes when sidecutting aluminum is to take a cheap airbrush and mount it to your spindle head on an adjustable arm, and use denatured or 90% Isopropyl alcohol pointed directly at the cutter from two inches or so away. Get one that feeds from a tube instead of the little cup on top so you can feed it from a larger bottle. Routers can leave poor finishes because there is not enough chip evacuation and lubrication for such a high rpm spindle, the air from the airbrush not only blows the chips away, it causes a ton of the alcohol to evaporate on the work surface which provides an extreme level of cooling, and the alcohol is an excellent cutting lubricant between steel and aluminum. I had an EZ TRAK CNC Bridgeport mill at an old job I worked at and I used this setup daily for cutting aluminum, I would go through a gallon of alcohol every week I used it so much, I had even hooked up a pneumatic solenoid valve to switch the air on and off with the touch of a switch. It's a very clean and safe method since hardly any alcohol pools on the surface, almost all of it gets blown or evaporated away, though you'll obviously want some form of ventilation.

[@ronidaffan5904]

Thank you for this tip pow !

[@JonasNeumann6]

Doesnt that cause a fire hazard?

[@TheExplosiveGuy]

@@JonasNeumann6 Surprisingly no, it really doesn't. The volume of alcohol being sprayed is so small and the volume of air propelling it so high that it basically leans out the stoichiometry of the alcohol/oxygen balance and won't allow a flame, you can't ignite the alcohol stream blowing out of the airbrush. A small amount of alcohol can pool on the work surface but remember that it's an airbrush we're talking about, it only blows about a half ounce of alcohol per minute which really isn't a dangerous amount since it evaporates away so quickly, even if the pool did get lit on fire it only takes like 5-10 seconds to burn away with a pretty small flame. You do need to be careful doing it in an enclosed space like a small room, it can eventually fill the room with an explosive vapor so you do need some ventilation, but that's really the case when using any solvents regardless of what you're doing with them. And if you're curious the cutter is not an ignition source, cutting aluminum does not produce any sparks whatsoever (you can trust me on that, I've been cutting aluminum for 17 years as a CNC machinist).

[@TheExplosiveGuy]

@@ronidaffan5904 You're welcome! Have you tried it yet?

[@sitgesvillaapartmentneilsc7924]

is the friction heat from the aluminium being machined not enough to ignite the vapour?@@TheExplosiveGuy

[@AgentWest]

Quick note about machining stepper belt pulleys: when possible, drill holes for every groove (space between teeth) before machining. Use a regular correct size drill bit, nothing fancy. This will save a good amount of wear on the end mill, drills are way easier to sharpen, as well as give much straighter teeth when compared to milling everything from a solid chunk. Of course those pre-drills would still have to be machined to size, but they do remove a large amount of material that the end mill won't have to.

[@MrBlakBunny]

Wondering, if you made a 3D printed CNC to make a Tank, could you argue that through the transience of properties that that tank was made by a 3d printer

[@ivanmirandawastaken]

I've thought of that more times than I'd like to admit.

[@pcnoob6623]

Simple,make a tank that only uses 3d printed tools to make

[@smorrow]

They already say this about ECM-rifled barrels.

[@WouterZtube]

That way of thinking would make everything handmade…

[@fog1257]

By that logic you could stretch it further by saying the tank was made by a bulldozer since it was used to extract the materials needed to build the 3d-printer.

[@mikeadair1708]

Damn. I was thinking of converting the tiny cnc I built to your plans to linear rails myself. This looks much more rigid, exactly what i need.

Hey Ivan, I got your project and was the best money I spend so far this year!!! Im into 3D printing so this is an amazing project to start the year in big :D Thanks and keep up the amazing work!!!!

[@tijhevella-verney3609]

another great project as always! Something I'd love to see is just how much play is present in the frame (particularly the Z Axis which can be measured by using a dial indicator). I used the same linear rails (I believe NGR12s) for my 'large' router's Z axis and found that the play was around 0.16mm... but my entire build is made from Aluminium (No printed parts), so would be interesting to see how the 3d prints hold up against such stresses. Great content as always!

[@bracco23]

the part that amazes me is how each machine is usually capable of working with way more strong material than what it is build from, making it possible in theory to build a machine with 3d printed parts, and then use it to machine aluminium parts to upgrade itself to be more capable. which you already did, but it is still amazing.

17:45 using a CNC is straight up hard. I went into it thinking it was going to be a lot like 3d printing, but it is not. There is so much to keep track of that it is really easy to forget something small that leads to a catastrophic failure.

[@ivanmirandawastaken]

Yes, catastrophic failure is always round the corner. Waiting...

[@darkracer1252]

just found this video. and that bit at the end really shows how powerfull this thing is. nobody should ever mill like that without cooling. but the fact that the machine doesn't care and just pushes through just absolutely amazed me. and with my background in cnc i can actually avoid those failures. (ps @Ivan Miranda) try some cooling. compressed air with a drip of cooling oil going into the line. you'll end up with a mist of cooling so you don't have the adapt the design to handle a ton of water. and aluminum REALLY loves it when cutting it) to the point that you can tell the diffrence between a cooled part and a non cooled part in a single glance.

[@negativeview]

This video couldn't have come at a better time. I'm currently designing something similar. Every other "3d printed CNC" has taken some choices in their tradeoffs I strongly disagree with (like EMT tubing). Yours landed pretty similar to how I want mine to be, so I can see something that works as a base, and then re-evaluate where my design and yours differs. For instance, I am currently on MGN 15 rails and was wondering if they would be enough. Seeing yours works with MGN 12 is nice. On the flip side, your belts are WAY thicker than mine, so if I run into issues, I know the belts are more likely than the rails to be the issue. Very helpful. Cheers!

[@AJLaRocque54]

Ivan, thank you so much for making this video. As soon as I purchase the tools, to make the tools that I will need for building the CNC, your machine will be the first thing I build.

[@tedgaunt3044]

Great design/build! I think you would find value in getting a true-flat surface for some of your construction/assembly. I noticed that your wood assembly table is fairly wobbly. Consider trying to find an old granite counter (sometimes available for free after a remodel). This will help your assembly to be even flatter, which could help for precision stuff like this cnc build.

[@shmafoo]

Your videos of your projects always inspire me to do more. I actually always wanted to build a desktop CNC machine. Sadly, I only live in an apartment and don't have a workshop.
