Finally the final test of DIY Dremel CNC, that's what we all have been waiting for! Thanks for the positive feedback about my project :) Share this video with friends and subscribe to my channel to don't miss my next projects that will also include this machine! Happy making!!!

[@leitoxweb]

Greetings from Argentina! i´m currently making this for myself and i wanted to ask you which model of Dremel are you using? i´ve adapted your design for a black and decker rt650 but i think dremel is best. thanks!

[@joetke]

In mechanics you got what you pay... not a secret.

[@nikodembartnik]

Greating from Poland! I used Dremel 3000

[@leitoxweb]

Thanks for the reply. I'll get one of those dremel to get it working!

[@dgengineers]

Fantastic work. Best wishes from Sri Lanka.

[@PiefacePete46]

You are an inspiration for me... I have had small machine tools for 50 years now (lathe, vertical mill, shaper etc.) I enjoy CAD software, and love Fusion 360. Recently I bought an Ender-3, and I have been having a ball with it. The next step is obviously a small CNC mill/router/engraver... your videos have made me realise that I just need to get off my butt and DO IT!! Thank you so much. :o)

[@Cybertruck1000]

The best thing about all of this is your enthusiasm. Is great to see a young guy being like this. Great ideas, great build, great enthusiasm. You are an asset to your family, and country. Well done.....

[@nikodembartnik]

Thanks!

[@trollenz]

You can be proud, you've put up a hell of a project ! Superb finish on the acrylic part ! Subscribed !

[@nikodembartnik]

Thanks!

[@JamieBainbridge]

Well done dude. Great your machine is working so well and you're happy with it.

[@nikodembartnik]

Thanks!

[@GuyRex1]

You are a very smart guy. Please keep making videos. We can all learn a lot. Thank you Nikodem.

[@georgejbaker]

Congratulations on your CNC build. Your enthusiasm and your talent are a pleasure to watch, I guarantee that you will go very far in your life! 👍

[@nikodembartnik]

Thank you, I am happy that you enjoyed my video! :)

[@joedog86]

You’re my hero! What a great project and video series. Very inspiring.

[@nikodembartnik]

Thank you :D

[@johnpearson9336]

Well done on an epic build!! Given me huge inspiration to build my own cheers

[@lapidations]

Congratulations, your project is beautiful! Thanks for the videos, this was awesome

[@forgotrafe]

Brilliant work, especially from someone so young. It’s clear you’re very proud of how it came out and you should be.

[@nikodembartnik]

Thank you! I am also very impressed, didn't expect it to be so cool :)

[@blueckaym]

I love this type of projects! And this one in particular just got to the top of my list (it's a very short list ... as I'm a programmer so pretty much the opposite of a handyman :)). I'm currently working on a DIY high-speed centrifuge for separating heavier pollutants from usable fluid (in my case resin particles from IPA, but I took the design from a waste oil processing centrifuges), and to be spin by a Dremel (4300). Since I recently realized that the centrifuge radius increases effective Gs linearly, but RPM increase is by its square (ie exponentially), and when I remembered that I already have a Dremel (I rarely use otherwise) I understood that I can scale down the centrifuge drum, and use the high RPM of the Dremel to get high effective Gs. For example I'm planning on ~7cm drum radius (as my 3D printer has small printing volume, Mars 3), but with ~10,500 RPM (which is ~ a third of the Dremel's max) I'll get ~10,000 Gs !! I actually suspect that the limiting factor would be the strength of the material (a though 3D printing resin - I'll have to experiment a bit with this before I recommend specific resin/or combo/). I've seen that the CD/DVD discs (which are about the same radius, but from considerably stronger polycarbonate!) shatter at ~22,000 RPM, so for now I'm planning to reach ~10,000 RPM, but might have to scale down if necessary. However such a CNC machine can allow me to make larger and stronger centrifuge drum! :) So this project got in the top of my TODO list! :)

[@rustedwatermellon9550]

I think you just convinced me to build to build my own! Good job and keep up the great work. I look forward to your new builds!

[@nikodembartnik]

That's great! Good luck with your build! Thanks :)

[@brucefox6580]

Outstanding effort!

[@jaredburton1929]

"Safety is number one priority." I see what you did there.

[@coreyhastings454]

Glad to see the final product! I am currently working on a version of this using my old 3D printer frame and guts, and the Arduino/control board you are using was perfect! However, the PSU mount you made for it has the holes in the wrong places. I didn't realize this until after I printed it out, so I am going to have to adjust the STL to make it line up correctly. Other than that, this has been a great series! Congrats! :)

[@l3d-3dmaker58]

amazing! can't wait to see what you do with it

[@nikodembartnik]

Me too :)

[@lyulf0]

Looking forward to the Aluminum tests :) keep up the good work Niko!

[@nikodembartnik]

Thank you!

[@thomasfulton6209]

Fantastic work I think Im going to build it!

[@skillmeup53]

Awesome project Nik, well done!

[@nikodembartnik]

Thanks!

[@RamjetX]

Good on ya mate. You look so proud. I'll have a go at building it. Well done

[@nikodembartnik]

Thank you, good luck!

[@markharder3676]

Nice job, Niko. One use for small CNC machines is carving out traces on printed circuit boards. The Cu sided PCB blank can be engraved with the mill bit. If the bit is small enough, I suppose even the small spacings of surface-mount boards could be milled out. This is a much cleaner way than masking and chemical etching for making boards. Because the underlying fiberglass/epoxy composite (used for the better boards) dulls steel tools quickly, tungsten carbide bits are used and even these must be replaced periodically. Cheap drill bits can be purchased on eBay or Amazon; though I don't know about flat milling bits. Another thing. If you make a base with a gridwork of holes, there are ways of holding your pieces with dogs screwed into the holes. I believe that this is how the pros hold their thin pieces down when milling them. If you use a steel plate for a base, perhaps you can use magnetic dogs to hold your pieces. Happy making!

[@aliyalnkomac9272]

dude, you ar eamazing, Hi from TURKEY.

[@edwinkania5286]

Very nice!!! Great Job!!

[@wubiantap3083]

Well done dude!!! It's amazing. Thank you so much for sharing.🌷

[@russellharper6583]

It was fun and I didn't even make anything. You made it look easy and I'm a backyard Geek!

[@MartinBgelund]

Build an enclosing to keep noise and dust from escaping.

[@Susipaddy]

I think you´re right. I have just been on a trade fair and they had their running cnc-machines in a enclosure and it was really quiet while cutting. Would be great to see this machine running in a enclosure and see the difference.

[@ukaszes6604]

Stary to jest super seria, szukalem wlasnie jakiegos fajnego projektu cnc z uzyciem dremela :) sprobuje go wykonac ;)

[@nikodembartnik]

Dzięki!

[@CNCminiProjects]

Great video... and what a nice looking CNC!!! Well done!

[@nikodembartnik]

Thank you!

Congratulationts for your excelent achievements !!

[@aarntsen]

Thanks for great inspiration, what an awesomely cool project! Thank you for sharing your talent.

[@nikodembartnik]

Thanks! :)

[@Dragon_flight]

Nice project! You are really skillful!

[@nikodembartnik]

Thanks!

[@ItSeemsDark]

Great job Nik , really came out so good ! Well done indeed!

[@nikodembartnik]

Thank you!

[@Perspectologist]

It was great to see it in action. It seems like it works very well with the refinements you implemented. I keep my CNC in my basement. I wouldn’t want all that dust near my 3D printers. Perhaps you could make a vacuum attachment and/or a plexiglass cover to contain the dust and maybe reduce the sound a little.

[@joetke]

6 minutes for this acrylic gear with neat contours... so gorgeous.

[@nikodembartnik]

Yes, this gear is beautiful :)

[@cwrigh13]

Great videos. Thanks for sharing.

[@klausnielsen1537]

Great result and video. Thank you for inspiring me.

[@nikodembartnik]

Thank you for comment!

[@iwasz]

I'm glad I see your video being featured on Hackaday news feed, and I like the CNC machine as well! I have a feeling though, that there is much more skilled fellow Polish folks that hacks great projects like this but we don't hear from them so often and I wonder why is that so. Is it like we are shy or something? Come one guys, spread the word (or prove me wrong).

[@randominternetviewer166]

there are some dremel extensions that are flexible where it can hold the bit on its end so the dremel can be hanged somewhere else. if you use that kind of extension instead of mounting the bit directly into the dremel, that could prevent any possible damage towards the dremel itself.

[@amigodesigns]

You deserve more subscribers, keep the awesome work!

[@nikodembartnik]

Thanks!

[@kirknelson156]

Turned out great, well done, been thinking about tackling one myself, your results are motivating me to give it a go :)

[@nikodembartnik]

Thanks! That's awesome, good luck :D

[@android4cg]

Awesome! Really great.

[@nikodembartnik]

Thank you!

[@trialnterror]

Great job sir, I’m on the same path as you, I just got my fixed gantry cnc router moving yesterday

[@nikodembartnik]

That's great! Thank you :)

[@lite_go_9565]

Cool! From Belarus 🇧🇾:)

[@radebel]

Awesome project!

[@nikodembartnik]

Thanks!

[@KodayW94]

I look forward to see some of the things you create on this little CNC

[@nikodembartnik]

Me too :D

[@aerohard]

If you could print a bearing support for the end of the Dremel it would add strength for the side loads and reduce the bit runout for cleaner cuts.

[@Brutaltronics]

Damn, looks great

[@BLaseka999]

What a genius...

[@msdesignru]

It's awesome project! Keep it up!

[@nikodembartnik]

Thanks!

[@lexss1]

You are a great fellow! I became interested in such things and you are the first who motivates me, thank you very much. And greetings from Ukraine :)

[@nikodembartnik]

Great to hear that! Greetings from Poland my neighbor!

[@MrNlce30]

Sound proof dust chamber and vacuum attachment needed.

[@paulbehrens5842]

Nice build.

[@nikodembartnik]

Thanks!

[@joetke]

You have about 3000 likes and almost 3000 collects on your thingiverse page for this project! Congrats!

[@nikodembartnik]

Thank you!

[@MikeysLab]

Awesome work man, thinking about jumping in and building one, hopefully with some modifications to handler a CO2 laser and a 5th stepper motor for tool rotation so I can use it as a vinyl cutter as well. Should be interesting, that you for an awesome head start, I appreciate your work!

[@paulcumber4732]

Nice job

[@joetke]

IMPRESSIVE! I did know that you won't give up this interesting project. I had some doubts about the dremel's holder mechanical stability (you need time to measure it though and fix would be just a reprinting parts away). You fixed those last issues and explained how. Thank you very much Nikodem. It's a great job and I plan to build one based on yours (an integral copy actually). The acrylic section is perfect and likely precise compared to wood. You took your time but this is an achievement dude!

[@nikodembartnik]

Thank you! I was really afraid that it wouldn't work as I wanted it to, but. a little bit of work and I made it work that good! I am still really impressed how this machine with 3D parts work. A lot of people told me that you can't use 3D printed parts for a CNC, so here is my prove to all of them :D Good luck with building your machine!

[@joetke]

PLA filament?

[@nikodembartnik]

Yes, that's PLA

[@olafurbanek1470]

Cześć Nikodem super to zrobes pozdrawiam i powodzenia

Dzięki!

[@user-rk6bz7sr4v]

Amazing！！！Thank you

[@vadim13597]

Cześć Nikodem)) To co zrobiłeś jest super. Też zapaliłem się CNC. Planuję to zrobić za miesiąc-drugi. Pozdrawiam i powodzenia!!)

[@nikodembartnik]

Dzięki! Powodzenia!

[@jvin248]

Build a dust shoe, it helps a lot with the vacuuming problem. Build a Thien chip separator for the vacuum so it can last longer or use a smaller vacuum that might be less noisy for the neighbors.

[@neiladams6214]

Exceedingly well done Nikodem Regards Dr A

[@nikodembartnik]

Thanks! Have a nice day :)

[@oeunsothearin9696]

very nice machine, I want it too

[@kudjeffrey]

You should try cork as a material. It is soft and you could make custom pinboards and cup holders like you did in this video with MDF. It would be interesting to see how well the machine would preform with cork of about 6-10mm.

[@merlingallagher4484]

You could build a box around the CNC filled with damping material to get rid of the noise. Also playing it onto rubber feet.

[@mohammedshwan8904]

Hi This is so good thank you But How much working area in cm And How much does it cost

[@benphillips2947]

Have you thought about designing a mount for a flex shaft attachment to reduce weight on the gantry?

[@joscelkentmanzanero1990]

Cool man! I watched your vid since part 1 and was inspired to make and design my own. I hope it works well. Thanks for showing the ropes! Oh and I think you should oil up the threaded rods more but anyway, really awesome!

[@nikodembartnik]

Thank you, yes I will oil them up, just have to find my oil

[@henning9201]

oh shit :D i started to buy all things and then i see the new video :D Tanks :D

Nie wiem ile masz lat ale super ze masz zajawke i tak mowisz po ang, projekt super, powodzenia!!!

[@nikodembartnik]

Dzięki :)

[@bandido7994]

Awesome, may I suggest you build an enclosure made of plexiglass for your machine? It will keep the dust confined somewhat and reduced the noise too.

[@gabrieljanikowski7415]

Łapka w górę za okulary ochronne.

[@guillermohurtado3759]

Hello, if it is time for the 2 engines on the sides, you put a central one, would it affect something or would the same work? Thank you.

[@jed2055]

In an earlier video, I asked if the 3D printing had been updated for the better stronger Dremel holder. You have answered that here. About MDF. I hope all who build and use Niko's budget CNC know that MDF dust is REALLY BAD FOR HUMANS. How you CNC AND contain the dust is up to the user BUT it must be done.

[@MP-mu1kw]

Excellent machine and video! I am new to CNC and wanted to know what speed settings i.e spindle rpm, feed rate, depth of cut, plunge or ramp rate etc that you used for acrylic gear you cut.

[@okiiPL]

Super robota! Moje pierwsze cnc było drewniane XD Teraz zrobiłem sobie frezarke ze stalowych profili 60x80 ścianka 3 i idzie jak burza

[@nikodembartnik]

Dzięki! Super, jakie masz pole robocze bo tak duże profile to chyba coś konkretnego? spawane?

[@okiiPL]

Spawane i szlifowane w mojej szkole a pole to ok 400x400mm

[@leoneldominguez5123]

Amazing!!!

[@nikodembartnik]

Thank you!

[@mahmoudmunia8450]

Hi Nikodem, GOOD WORK! are STL files updated and ready for printing? also don't you think that there is a problem of making the outside bearing holes' edge of the z-axis carriage too slim?

[@zacharygilbert3919]

Youre a boss!

[@sasandabirian8768]

Wow nice video man! I have a feeling you're going to build a bigger CNC in future and also mill aluminium to build molds and inject it with hot glue! ... Yes I can tell the future lol.

[@TheSmith2409]

can you make a tutorial about how to calibrate the machine? (how you adjust the height of the dremel, because I see when you put the paper, but I don't know how to adjust it. Thanks! Great project!

[@SiddhiCoachingClassesEducation]

nice project can we increase size of working area and how to connect end stop ..

[@TheZeglarz83]

Zazdrościć :)

[@antonioivanferreyra1953]

Hello!! You can upload the carriage design and hold the X axis for 8mm rods ?

[@ercankr75]

Good thankyou

[@saladiis1117]

Great! but dust from cnc mill litter ur 3d printer and room! print the brush with connector for vacuum and use acrylic box around mill

[@mattewblack6549]

Hello, how did you set home position, working area and endstops?

[@JM_Tushe]

Cool.

[@Mujaki]

Perhaps the mount that holds the rotary tool could also have an addition to hold the end of the vacuum hose? Let it clean up as it works?

[@babadito]

Hi! Does it works to do PCB circuits? I mean to do the pcb and the perforations.
