IndyMill - Open Source DIY CNC Machine #1 Parts 

Check out indystry.cc/indymill and subscribe to the newsletter to be up to date with IndyMill project! You can also find here a table with parts that I have as for now. What do you think about IndyMill? Can't wait to mill something with it :D

Some small tips: 1) don't restrict the machining method of your parts. You may find a CNC shop that can cut your material at a cheaper cost than laser, to similar accuracies. This is especially true if you wish to sell kits. 2) don't accept parts that have missing or wrongly made features or dimensions. When you send drawings and files to a manufacturer, make sure you have all of the following: .STEP file of your individual parts (dxf or dwg if laser files), 2d dimensioned drawings of each part, and an assembly drawing of your part if the parts are intended to be assembled on each other. This allows you to point out their machining faults (if any) as well as help them highlight issues they may face. You can't do this if they don't have your drawings. 3) you can get the fabrication house to clean and process the parts for you, such as filing or bead blasting to a desired textured finish. This can save time spent on paint prep. Really enjoy the video. Can't wait to watch the next one!

I think what you're doing is amazing. I just wanted to say thank you for taking the time to show people what you're doing and being brave enough to share it. The way you go through everything and the presentation of your videos is excellent. I'm thinking of building my own CNC machine, not a kit one like you see everywhere, but my own design. My thought process was a lot like yours: combine aluminium and 3D printed parts, but I have no experience with 3D printing yet. Your new design has inspired me - I'd been thinking about using 3d-printed prototype parts in place of simple 2D aluminium parts that can be cut on a fibre laser, and you've completely solidified the idea in my head.

Hello ! I watched all the videos of this part and they are just amazing ! The machine came out great ! So for anyone watching, I contacted Nikodem for more infos, his answer was extra fast, straight to the point and really really helpful, Thanks Nikodem ! I will buy the plates and the PCB and start building my machine based on your plans.

Again a nice project, I will check this with attention, as a fellow maker, I love this kind of DIY CNC Project ! Keep up this amazing work.

Bloody awesome, mate. Marcin Jakubowski would be proud. Keep up the good work!

Super excited to see the progress!!

I was about to start building another DIY cnc, but I think I'll wait for this one, looks really promising! Good job mate!

Huge thanks for sharing it for free. This is very inspiring, will definitely link to you after building one.

amazing craftmanship mate! youre going places.

Excellent job! Thanks for sharing this with us. Stay Safe!

I remember the first video and was hooked. This is cool man, can't wait to see how it develops!

I like very much what you are doing. You have a logical and precise mind. Good video.

last 2 weeks i work with video editing and now understand how much time you put in your edits . good job bro, you are getting better on each video :)

aaah here it is! Was wondering where this mystical IndyCNC was ;-) I'm glad you got to start on this project, I really enjoyed your DremelCNC. I haven't built one but now this one is here, I wonder if I should just wait and build this one. I have access to a laser cutter at work and can have parts like this cut to size which makes life easier, although i've always been told that the hole size on a laser is dependent on thickness especially for the quality. i.e. they don't like cutting 2mm holes in anything thicker than 2mm, 3mm holes in anything thicker than 3mm etc.

Your first cnc was amazing 👏👏 looking forward to this one 👍👍

Great video, i really love your CNC projects! I decided to build my own CNC and now i can not stop :D Thank you and greetings from Russia!

Best Timing, needed a break from learning🥳

Thanks for open sourcing it!

Nice video! Right now I'm in the process of designing my own CNC, are there is some stuff I might wanna add: - the aluminium profiles are quite small. My machine will have a similar workspace of around 600x500x100mm, yet I used 60x60 and 60x120mm extrusions - I don't know if you already plan to do so, but you can fill the aluminium extrusions with sand to make them more rigid and the machine quieter, once it's finished. Just seal the ends with glue, 3d printed parts or something like that - the stepper drivers you bought are quite cheap and not as reliable as other options. You should check out the products from leadshine, they have very good digital drivers - the linear rails you got are probably cheap hiwin clones with mediocre built quality. It is always recommended to take the linear blocks apart, degrease them and even replace the ball bearings with better quality ones for better accuracy and reliability. - if you don't care a lot about noise, you might want to consider a trim router like a compact model from makita as your spindle. They are high quality and very safe to use in comparison to other models from China, yet they are pretty loud in use.

Fantastic! My 'most waited for' video has arrived!! Goody goody!!! Thanks Nikodem. :o)

Looks like a good start!

Another great video! I love your projects. I’m looking forward to part 2.

Good proyect Nikodem, I really like your channel. Regards from Spain

Wowww already a new one!

Great video as always, would difinitly buy those steel parts!

For the very first time, I can't understand those thumb-downs... That won't change the great interest of this project at all though. Nikodem, since the very start of your channel, I have had the feeling that you'll gain step by step a great audience. Because of your fertile imagination and that willingness to make ideas a reality. Here we are! Already +40,000 subscribers. I'm really happy you reached that milestone. I was not wrong: you're a hard worker and a creative guy with talent and knowledge. It's not flattery, I hate that. This channel is among the rising ones for the reasons I just listed. Keep it up! This project is more professional with heavy-duty parts and so inspiring. In addition you give work to people who do need it. It's a social involvement too. Glad to have discovered your channel Nikodem. Vive la Pologne et sa jeunesse! From France, with admiration.

Great video, love the design and nice job at your website. Maybe try aluminum insted of steel and try to mill/drill them on a dremel CNC. And a tip for a dremel CNC, make an air hose that will blow away aluminum from cutting area and cooldown the tool a bit. Keep up the great work!

Nice beginning video for this machine.

A Helpful Genius. Thank you.

I'll take the parts of the Dremel CNC and build this one, nice design!

👍👍👍 can't wait to see it's working

I enjoy your videos. Just a tip for paining. Rustproofing is quickly and effectively done using Rustoleum spray paint. It is a US product but is readily available and reasonably priced here in Australia. I presume that it would be available in Poland as well. It has much better coverage and finish and it also bonds well to most plastics including PLA so I use it for most of my prototyping. Cheers. (not a paid ad).

Awesome. I'm still building my 3D printer to be able to print dremel-cnc parts, but I'm already excited about your upcoming videos. One suggestion tho, you could make a few videos explaining the design choices. Obviously not everyone will be able to get the exact same parts and probably has to use substitutes, so it would be interesting to hear your thoughts about the problems or parts one should avoid for whatever reason.

Awesome video! I plan to replicate, using aluminum for the plates (at least 8mm, and the .dxf files as per your website above). Thanks for posting!

Super video ! pozdravujem zo Slovenska :) Velmi sa teším na dalšiu časť.

świetne wideo, dzięki!

Man you have done a large amount of work and this is an awesome project especially for people that want a decent hobby kit to start in CNC. I would buy all the bits from your website straight away if you shipped to Australia but unfortunately that doesnt look to be an option. I can get local suppliers to make them but I would have preferred to buy direct from you but that is ok. Thank you for your work.

Nice project, nice spirit 😊👍💪💯

Hey, cool design! Great idea! I would use extra bearing blocks for the ball screws. Can buy via aliexpress as set.

Nice editing.

Dobry projekt Bartek,może się skuszę . Pozdrawiam

Looks really cool! I'm looking forward to the next video :)

Once you are ready, maybe even make the plates available to purchase electronically by way of CAD file. That way if shipping is too expensive we can have them made elsewhere. Just an idea, keep up the great work!

Do you anticipate being able to mill mild steels or stainless steel with this machine?

This is a great project! Thank you very much for shearing it! Can you give us files with dimensions of metal parts?😇 I want to start building it right now and give you all good feedback with ideas and potential updates)

The V-slot profile 2020 has good M5 holes, you don't need to pre-drill them.

Hi Nikodem, Outstanding project, looking forward to it. I have those stepper drivers and noticed that the circuit boards can be very close to the case. I am thinking of using some insullated waffer. :)

Cześć ;) Już się nie mogę doczekać końcowej fazy tego projektu! Mała prośba, jak nie będzie problemem dodaj polskie napisy, bo te co generuje youtube tłumacz zlewają się z sobą ;/ No i oczywiście linki do części od polskich dystrybutorów :) Pozdrawiam ;)

Amazing! You should try to cut the steel parts in a cnc plasma cutter or I'm waterjet, is much cheaper

Nikodem, Thank you for all your hard work creating the IndyMill. This is the exact form factor I have been looking to build as my first CNC. I was wondering, based on your design, what is the working area of your design? I would like to build one that can handle a working area that is roughly 915mm x 610 mm. So, I am not sure how long and wide my setup should be. Do you have a sizing calculator?

I think an easy / cheap way to use an Arduino with grbl is the Arduino Nano with a Nano expansion board ~4€. I use this with the TB6600 for my Dremel CNC. But I will also build your machine when it is finished. Because I am currently not satisfied with the rigidity of the Dremel CNC. I'm really looking forward to Part 2

Brilliant! I love it. Can you add a link to the laser cutting company you used?

Nice work Nikodem! Gonna build your version. I was planning to build a MPCNC but yours look more mature. Is it wise to replace the steel laser cut pieces with aluminum? Perhaps 10mm thick?

Hey bro, very nice build and the free instructions are just awesome . I need to build one a bit bigger, can i scale it by just getting longer rails and balls crews ?

You should compare to the Shapeoko XXL with the HDZ or Z-Plus!

Thank you for the great video! I am really looking forward to this series! A few tips and or questions 1. As far as I know there are 2 Versions of this profiles one with a bore for M6 and for M5. Is there a reason why you didn’t use the M6 Version, with which you wouldn’t have had to enlarge the holes? 2. When boring, milling or tapping Aluminium I use ethanol and not WD40. I don’t know he specifics but it just works better. Datron uses it also on their machines. 3. When I order parts from a laser cutting service they mark the holes which are to small to cut. Maybe you could ask he service where you ordered the parts if they could do the same

Just one thing about the paint, I use the same brand (here is made by azkonobel, Idk there), and its really good but... primer or lacker, the paint by itself reamains like pay doh if its applied directly over metal.

Nice. My words in english are not enough to describe what I think. But its still great to look at your Projekts. 👍👍👍😍

Like what you are doing. Would 3mm mild steel plates be thick enough. Would reduce the weight a bit. Also found that laser cutting can be cheap enough if you find the right company. Also you would be able to get smaller holes thru 3mm palate.

Have you released a step file for the entire machine? All I have found are step files for the individual printed parts. Thanks for all your work!

Solid project. :) my tip is to use rubber foot to reduce the vibration and noise.

great project! Thanks for sharing this. Did you buy the v-rail extrusions for a reason? I haven't watched your second video, but the linear rails make me think you aren't using the v-rail feature. What are you going to charge for the metal plate kit? Any interest in doing it in stainless steel or aluminum? Thanks Doug

Really excited about this project. When is the next video out @Nikodem Bartnik ?

FIIIINNNAALLLYYYY!!!

note to anyone trying to do this if you know someone that can plasma cut just let them pierce the small holes (it draws an arc in the center of the hole which creates a nice pit for your drill to go into like a center drill)

Excellent project

Hello Nikodem, At first i would like to thank you for all your work you are sharing to us, thank you so much. i'm on my way to build it, but i have my first question ^^, which drill mounting are you using to drill holes? it look like aliexpress one, but which one (if you advise me to buy this of course) cdly.

Nice work. Waiting for first aluminium chips 👌

you work very nice

Cool Video edditing!

early gang im still building my dremel cnc i have been waiting for the 12mm rods for months adn due to covid 19 its taking longer edit: didnt ealise i was this early 15 seconds

Hello! Can I add a 15/20w laser to this cnc? What have I to change in order to achieve that? Thank you very much and great job!

G'day, what are the material to be cut limitations on this? I've been looking and cant find this info. Will it cut steel or aluminium? How thick a material can be cut in various types?

Sooo, when you put that thingy together, could you mill the metal pieces and sell those possibly? I have no idea where to begin finding someone that could laser those for me. Alternatlively you could place a larger order with your supplier and sell them as well.

Hey nikodem would I be crazy to substitute the aluminum parts(except the rods and profiles) for wooden parts preferably plywood

I might be interested in the steel parts as I’m in the EU (at least for a bit longer)

I watched all the advert in between to suppor you

Hammerite sie kładzie troche grubiej 2 razy max, I tu tesz robi mały problem, dlatego rze nawet annodizing robi kołt jakiejś tam grubości, ja bym sprobował doszlifował na punktah kontaktu tych rails do stali, I zabespieczył olejem jak acf50 kture bozwoli na dokładny kontakt. Jeśli kiedy kolwiek rozbierzeasz starą maszyne to właśnie takie rozwiązanie jest zastosowane. Ale super video, I czuć taki fajny entuziazm, do budowania motoruw by mi sie the pszydało do szybkiego prototypowanie, I morze gdybym zrobił to całe z stali, I sprenrzyny na pionowym axis rzeby odciąrzyć śilniki to by wtedy z jakimś zarąbistym motorze móg zrobić super mince cnc do wszystkiego od stali to plastiku

You should 3D print some soft-jaws for your vice so the vice won't mark your aluminum. You need a drill press.

you started a great project! very cool! to improve precision in building the structure I would advise you to remove the paint in all those places where the steel plates are connected to each other (for example if you have to join two pieces of steel at 90 °) the thickness of the paint could give stability problems with the finished structure. The 12 brothers you showed in 04:03 probably are named sliding bushings or linear bushings ( no no: linear bushings are for rods). Do not remove the plastic stud inserted in the sliding bearings but make sure that it is pushed away from the rail, while inserting the bearing, otherwise you could lose all the balls of the bearing Go ahead Nik i'll follow you ! See you soon!

Cool!

I've been torn on what to build. I was considering just buying a little 3018cnc to mess around with but I'd rather put the money towards a decent machine similar to your design. I like the size of this machine. I already have two nema 23 motors from an old project but I need new drivers. I also have a single big nema 32 but that's overkill unless I'm building a pretty big machine.

Amazing

Dobra robota, no i ten, przecież jak będzie gotowe, to możesz wykorzystać to cnc do zrobienia części z alu do konstrukcji następnej, praktycznie koszt wykonania odpadnie (poza kosztami eksploatacyjnymi) więc można zainwestować w aluminium.

Hi, I've just come across your vids and i'm very impressed, so I decided to purchase your plans, but the problem I've got is your parts list.... Some of the links send me to 'V' slot extrusion and others to 'T' slot, is that intentional? The link for trapezoidal lead screw is asking for pitch and lead dimensions/sizes? Linear rails links are asking C or H? Stepper motors spindle sizes?? Any chance you could clarify thanks. 😊

super robota, jakiej średnicy sa te ballscrews? widzę na internecie ze sa dostępne rożnego rozmiaru

I was designing the same thing since I'm a machinist and itd literally be easier for me to make the plates than 3d print lol. are your linear rails replicas from China? do they bind at all? make sure you lubricate them!

Fajny projekt, ja aktualnie robię mpcnc primo

Hey Nik, is there any chance I could get the drawings or files for the steel parts? I have a CNC and I thought of making them out of aluminum. Are you you in the states?

This is a great project because I'm thinking about building a CNC. How much have you spent so far?

Great video, did you consider doing waterjet?

Hello, good job! What type of steel did you use for the parts?

what controller board u use for this motor driver ?

nice vid again mate. if you need laser cut parts i can send you what you want because im a programmer of our cnc machines at work! We can cut up to 12mm steel. I already lasered 2.5 mm holes just fine in 8mm steel sheet!!! (It is possible)

Looks nice design, however flex at x axis is bit worrying, i suppose Mgn rails makes it bit stiffer

Hello is it possible to print your aluminium parts ? could it be stronger enough ?

Nice Project. How much did the custom steel parts cost?

Okay so where do I get the aluminum parts with the holes

Hello guys, someone can tell me what pitch and lead ( in mm ) must i order for z lead screw?? Thanks to u
