This is definitely going to my "to do" list. Great, simple design...and great video too.

Whenever I've been warned that you've posted a new video, I first look at its length (hoping that the longer the better ;), then I schedule the best time to watch it. It's a piece of entertainment and a great piece of achievement as well. We're on sunday and I appreciate your effort, your seriousness and your pretty good imagination. Thank you Nikodem. I'm sure that this spindle-based CNC will be much better on all aspects than your very good dremel solution. Can't wait the very first tests. Have a great week!

I really want to thank you for making this free and available for everyone. I am currently making my own and I can't wait to start milling things.

Glad you did a spindle version. I just finished doing my own which I converted from your Dremel CNC. Look forward to your spindle tests especially with Aluminum.

Fantastic upgrade. I have been just finished printing all the parts for the first version of your Dremel CNC and am waiting for some of the other parts to ship from China. Now, instead of purchasing a Dremel, I have just placed an order for the 500w spindle, and will have to print the Z-carriage for the aluminum spindle mount. Thank you for your great designs. You are inspiring.

great project. if you going to do second part, consider to explain configuration of the arduino with the grbl software & create easy cad example (fusion 360) project and run on cnc . most of the RU-vid CNC show how to build the machine but don't show clear the step of software,configuration, CAD and run projecton the cnc . cheers from Australia nice to see younger generation with great skills

I'm surprised that you never made pre made kits, I would buy one In secs

Oglądam ten film i morda się sama śmieje :) Świetny koncept przeprowadzony od początku do końca. Inspirujący i przesympatyczny gość z Ciebie! :+1:

gościu jesteś mega ta maszyna jest świetna i to wykonanie. Twój angielski jest tak dobry że przez pierwsze 10 min nie zgadłem że jesteś z polski haha

The best things is providing spreadsheet with the required parts! Thank you very much :D

Loving all the projects. I'd like to make a suggestion for your drill press. Make a block the same height as the base or your drill press so you can stabilize the work to ensure you drill a straight hole.

You are brilliant! I just discover your channel and it is impressive. Congratulations!

Hey Niko, thanks for your design! I upgraded it a little bit to get more space and mill heavy metals :DD Thanks ❤

Dear Nikodem Bartnik, I have built your 3D Printed CNC and started milling some calibration objects like a 20x20mm square out of 3.5mm acrylic. The problem I came up was that the x and y dimensions work just fine and I was able to calibrate them just fine but the z axis slaggs down in the milling process so that when it tries to mill the tabs and cut the piece free from the material, on the side where it starts it cuts way to high (like 0.3mm) so that it leaves some material on that side then it continues with the next side a litle bit lower then with the next one a little bit lower and then at the final side it cuts how it should (cuts through the material and leaves the tabs). I have moved the x and y axis very close to the bottom plate to verify that my build is not the problem. So I am assuming that it is a software problem but I have no idea where to look. I am looking forward to hearing from you and I hope you can help me P.S. I can send you some images of the parts that i milled.

For my build I 3D printed cable carrier down the side it made it look great and all wires neatly tucked away

excellent video, beautiful completion of the spindle with the renovation!! congratulations @nikodem ... Greeting from Argentina

Really nice video, I am always get inspired to make this kind of machines after watching your videos

Great video. This is one of the few times I've been able to say that I like the music in the video.

Great music, man! I'm used to hearing plastic techno muzak playing in videos like this. It really does make a difference!

You don't know how much i love you ! Thanks you very much for this awesome project ! A thanks from France !

Impressive workmanship!

Good job! Keep on rockin' !!!

So cool. Love your attention to details, very talented for your age, you have a bright future and have earned yourself a new subscriber. 🤙

With the spindle power supply, could you not replace the old school pot for speed control with a I2C digital pot and possibly an op amp to allow the Ardino/PC to control the spindle speed? Not sure if GRBL supports this, but would be a simple enough code modification to make it work.

Very useful instruction with item lists. Thank you very much!

Still such an awesome project!! The new one looks slick!

Great video. I’ll be buying extrusion 😀I’m making a start on the 3D printing straight away !

Excellent work! I'm always inspired by your videos. Do you rent a workshop space? I looks like you have a such a perfect little workshop set up.

Easier, and better allowing more materials to be worked, would be to replace all of those linear rods with linear rails and blocks. More expensive but well worth it in the end.

Great videos... and thanks for sharing part list... btw its 12mm rod? if i upgrade X axis more length 14cm is 12mm rod can hold weigh of spindle? thanks

Amazing Work man and thank you for the great effort to illustrate every step. I have one question, why did you put taps inside the aluminum profiles? I don't see any use for them

Thank you so much! Appreciate your content! :)

what a very clever and helpful young man thank you

I have a lot of respect for you and built a device according to your data. It's just perfect. I'm missing the limit switch step, do you have a chance to explain this issue?

Very cool, what size 3D printer platen is required for these 3D printed parts? Thanks!

Damnit I hate videos like this. Really well done, great accompanying material. Looks like I've found another project to spend time on!

You are leggend !!! Thanks very much for the time to spend for these project !!1

Very nice build and excellent video. You are very talented. I really enjoyed watching. I am going to build one and was wondering what would be the largest frame that could be built with this design? I plan on using the 500 watt spindle or maybe adapting to a finish router. What are your thought? Cheers…

I really love the music in your video, are there links to the songs anywhere?

Hi Nikodem, thanks a lot for the great work. Has the issue of backlash been solved? If so, how? Thanks.

If I want to make cnc 775 motor instead of Dremel what I have to do please reply Thank you so much for such lovely cnc router

I started building the dremel cnc, thank you for the good work and offering this project! 👍 Would I like to know would it be possible to run the software from a esp 32 module? Only because I have some spares laying around and wouldn’t have to buy a arduino uno even if it’s not expensive…

what kind of leadscrews did you use 8x2 or 8x8 ones ?

you can't really use steppers for thrust support. They'll work for whip, but they use a spring washer for lash control and that isn't the greatest for backlash. This would probably be fine for 3d printing loads, but not for CNC routing. i would redesign for a captured pillow block if i were you.

5:23 You may want to try sandpaper on a dowel instead of the small round file.

Witam. Super robota. Nagraj to też poPolsku.

Excellent video! Would love to hear from those who have built this CNC. What is the useable workarea size of this CNC, especially when used with the new 500W spindle?

I like the color of your blue PLA. Where did you get it? It's hard to shop for PLA online because it never seems to match expectations.

Nikodem, what is the accuracy/precision of this machine?

What a great video series, I've subscribed! I do not have access to a 3D printer, have you thought about putting a packet together with all of the 3D printed parts and charging for them? In fact, what about everything, except Dremel, that is needed to build one of these, screws rails, printed parts, electronics etc. I know I might be interested, depending on cost and shipping. I can't wait to see the second part of this video. Thank you again for a wonderful video series! Pam

Hi Nikodem, do you have the updates 3D STL files to use the spindle (replacing the Dremel)? Regards.

I wish I had some place like yours. Great video. :)

Question: shoudent you be able somehow to controll if the dremell your drill anyway is spining so of you want to make an more complex operation you coud

Do you think buying a stronger/better spindle andpaying to get metal 3d parts would make this able to do some aluminum? Just thinking.

You are a very talented young man!

Sick project man! what would be the budget for it? considering I have a 3d printer

Hello from Moldova. You are cool man. What do you think about parkside tools? Just i saw parkside screwdriver in your video. Thanks.

I am using the same spindle. The noise is caused by the fan connected at the top of the motor shaft. While running at low speed, I shaved the fan like a wood lathe to balance it. It is now very silent.

The arduino UNO you're holding in the video and the arduino UNO in your instructables looks different. What is that blue one you're holding in the video please? Link? Thank you :) Also why did you only plug in a power supply to the stepper motor shield and not the arduino UNO itself?

i just want to point out that th3e CNC shield you have isn't compatible with GRBL 1.x it was designed for GRBL 0.9 and lower, and there were some major pin swaps between 0.9 and 1.x

What type of filament did you use for the blue parts? I've been considering either PETG or ASA for my build.

точность и жесткость этого станка просто невероятная !

balance your fan on top, you can get it a lot quieter ;] try rotating a few times and test, I had that problem with my 300w motor

HIi Nikodem, great project !!! a lot of fun building it. however i'm facing one weird issue once i switched to 500w spindle, z-axis no longer seems to hold the position of the drill, meanining it drops 1-2 mm from the position it should hold. did you face similiar issue maybe? i dont know if this is caused by bed wiring (no shielding) or i fried the motor somehow, funny thing is it seems to be an issue only when spindle is turned on ,

great video. Is it possible to mount ER16 chuck holder insted ER11 with that spindle?

That's awesome! :)

Hey i didn't understand exactly the software part what you did outside Actually i have the cnc machine but i cant use it with my apple MacBook can you please explain it simply how to make it work on my apple

wow that is some top tier filming

Hello, I have built Dremel CNC, it's a great machine. I have used it for mill some pcb and cut acrylic. It's wonderful. Now I want upgrade to 500W spindle. Could you share the stl file for power supply support ? I cannot find it in your thingiverse project. Thanks in advance.

Hi Nik , Thanks for this wonderful project, I want to know how much time did it take to print all 3D printed parts?

Wow, amazing video. Just found you by accident while looking for something else :-D Subscribed. What is the software you are using? CNC Jazz or something like that? Thanks for the answer (and the amazing project).

Can you use standard threaded rod instead of this with trapezoidal threads?

looking to start printing today.. how does it hold up?

Great design, but why use aluminum extrusions for the base? Is there any reason not to screw it down to plywood or MDF?

One question: how to attach the 3d printed part to the aluminum spindle clamp? Was not shown in the video. Thank you.

Great video Nikodem ;-) As always ;-)

Hello, This is an amazing video but I am a noob at electronics so I was wondering how I would connect 2 motors on one axis on the cnc shield?

Hello. I really like your design of this engraver! especially with a brushless motor. How rigid is this CNC? Would it be a lot of work to use 16mm rails instead of 12? I see that there is quite a bit of room for increasing the diameter with linear bearings. I could try it myself, but I don't know how to edit STL files. STEP would be much better.

Hi Nikodem, love the machine. in the process of building one myself. I've found an error in the stock list. What size screws are you using for the part in the video at 9.25 . In the spreadsheet and instructables M3 x 20 are stated. however they are not long enough. I believe that was before the update of the x axis carriage? Hope this helps and you can update the list! ps. What size did you use as i need to buy some now! ?

please tell about power supply for cnc shield .how much voltage and amps.

Great videos. Can this be made bigger to accommodate larger work pieces?

Hello Nicodemus, how did you install the motor on the z axis because I can only put two screws on it Διδ you put glue on it

just in case someone has the same amount of braincells as me, the collet mentioned in the intro is not the outer part. Its basically a metal thing with cuts at one end that can be clamped together by the thing you put it inside (hence the videos where you see people using a wrench on that outer shit every time they switch endmills (bits). figured id save someone the time of googling here. ER11 collet is the shiny metal thing with "blades" / cuts, thing around it is the shit you twist and tighten. This has been your daily dose of Explain Like I'm You

Great work!!!

We can use dampers at the bottom of the machine both indymill and dremel to arrear the vibrations right??? It will arrest a lot of noice too

Great video. I would like to see one using PETG with the 3D printed parts. Also on a note of 3D printed parts. What orientation do you typically print them, would be of great assistance.

Hello, great job, I have made it, but I have problems when cutting acrylic, the cut material stays stuck to the cutter, could you please tell me what are the cutting parameters for acrylic with this spinlde thanks you

Hi Nikodem ! Could you explain how you manage to make your leadscrews work with two nuts ? Thats not possible according mechanical basics, except if you use a particular adjustment device ? Which and how ? Thanks.

Amazing project idd!! I just can't happen to find the dimensions for the 3D printed parts anyone facing the same problem? I am planning to redraw the parts on Solidworks and change some of the dimensions but to do so I need to current ones at first.Anyone an Idea?

Good job! That was vibration not loud spindle !! Spindle should not be loud on high speed- the collet just needs to be balanced professionally then it won’t vibrate when fast turned. Good luck.

GREAT JOB !

Nikodem what about grounding? i saw on different sites that there is no warning and info that the potentiometer is also dangerous to use as much as whole power supply of the same reason- no ground.

Perfection, ♥️.... Cheers from India

great job. Your work is amazing.

Hi, very great work, would a Dremel 4000 or 4300 also be possible? Above all, what is the latest status for the Dremel for the STL files. Thanks keep it up ---

Any update on the availability of the 3D printable Z-carriage for the aluminum spindle mount? I have downloaded the DIY Dremel CNC parts and have started printing everything else but would really like to go with the spindle shown in this video.

Awesome video!

i'm struggling to find a forum, website or anything besides the instructables and youtube. Are you planning a community hub?

I just want to point out a detail that was missed in this video that I had to go looking for - the holes to drill in the long pieces of extrusion (with the pillar drill and 3d printed guide) should be 6.5mm
