I must admit, most of this is still foreign language to me. I'm 74 years old with a high school education. I have become very interested in learning how all this stuff works. I bought an Arduino kit but then I got high centered and have not gone any further. I need to find a place where I can learn and ask questions. I can't tell you how much I appreciate you doing these videos. I only wish I could absorb the information as fast as you talk. I will be going back and re-watching them all. I also need to get the stuff to build some of what you have shown. I got interested because I want to build some sort of CNC woodworking machines. Thanks again and please keep up the great work.
John, Great video! Not only am I interested in virtually 99% of the content of your videos, your enthusiasm is very contagious! Machining, Tormach, CNC, Arduinos, control... I love it all, and your presentation style is perfect for us home shop machinists and tinkerers. I see 100K in your near future John. Good luck and keep it up! To those reading this who are new to the NYC CNC Channel; I've been watching John's videos for several years. You owe it to yourself to see where he began in a small apartment in New York City. I suggest that you go back and watch all of his previous videos to really understand how he became what you see in his current videos from Ohio. As a simple home shop kind of guy with many of the same interests as John, I have thoroughly enjoyed watching his growth and learning. In the process I have learned much more than I ever thought possible. But hold on, it's quite a fun ride! Disclaimer: I have never met or spoken to John personally. I just admire what he's accomplished and demonstrated what is possible.
Am building a pen plotter, I already bought the steppers, dude you are my hero, it's a blessing I followed your channel even before I started thinking about building a cnc.
I just woke up and watched this with my first brew of the day and even in my John Hurt waking up in Alien state I could follow all of this. Beautifully explained John and your enthusiasm is infectious!
I'm back again bro.. I watched another video from another content creator with this subject and he went deep into the electronics side of things which is so hard to find others doing the same. Most ppl gloss over the electronics but what they don't realise is this is the part most of us newbies really struggle with and would very much appreciate u guys help out her with some indepth videos on the set up and wiring and not just show a diagram and sdpeed up the video to 25X's normal speed.. LMAO.. I hope u don't take my comment the wrong way my dude but it needs to be said now and again
I couldn't count the number of times I said to myself (out loud), "This is awesome. This is sooo awesome." Thank you AGAIN for posting a continuation video on this subject. Thanks for walking through the g-code as well. That cleared up so many questions I had. I'm going to check out your site right now. I feel like I just have to buy something from you or if you have a donation arrangement, send you something so you can continue these projects. You've done such an excellent job providing content and helping me learn it's the least I can do!
NYC CNC Hi John, thanks again for always replying! I really wish I could make it to the open house. I'm in Michigan, North of Detroit and only but about 5 hours away. Since I can't make it though due to scheduling to the open house, I'd like to maybe help out in some way. I'll shoot you an email with what I had in mind. :)
Your videos are awesome man. A viewer can really follow along and learn as you show and teach your concepts. Your enthusiasm is contagious. Thanks so much for making them. Hats off to you.
If there is one video out there that can convince someone that it is not hard to build a cnc for hobby use, it is this one. I like the fact that the cost of the individual parts is spelled out - as well as the limitations one has with these parts.
thank you John! your friends from Yachiyo here.. i have been interested in Audrino for years but never broke the ice and bought one. But after this video im doing it! lol
I work as a software engineer, but mechatronics has always fascinated me. I started hobby electronics a while back, now I'm working on stepper motors. I just took apart my old printer and salvaged quite a bit of hardware :) I'm going to create a candy machine and use the printer / scanner body :D
Cant wait for more videos. Been thinking about making a CNC for a while to learn and to use, after putting hours of research into it over the past few months to make sure I dont make a mistake with my tiny airtight student budget I stumble on to your videos where you answer questions about technical and not so technical aspects, make it on a budget and maintain a level of quality. So pumped for more. Thank-you for these and I request a quick DIY CNC lathe once this project is complete!!
That is a great project! I retired a year ago after 40 years with GE as a Tool and Die Maker. I am getting started with Arduino and plan to use them for projects in my work shop. That machine you built may be on my list of things to work on. Keep up the good work and thanks for the video!
This is the first video i watch in your series, but gosh - You are my new hero, for explaining in an easy way... I will keep track of you in the future..... THX a lot..
i see a lot of passion in your videos , i am sure yo already contribute a lot to Human Kind. your videos and techniques helped me as inputs for lot of my work. Thanks a lot
Love this video, just finished my very first Cnc router, based on grbl and arduino. It can mill 47x47cm, and cost less than 100 dollars. I would never been able too put this togheter if it wasent for people på UA-cam like you. Actually it was looking at one of your videos that got me inn too it, and i think so far that its been a great Journey. So thanks again for putting your effort in the videos you make☺
+NYC CNC Hi thanks for response☺ for now i have only milled some wood pieces for the enclosure for the electronics too the Cnc, still try too learn difrent software, and fix all the "baby" issues that the machine got☺ this machine was just for test purposes, too see if i could design and make it. So next project will be too make a stronger one for aluminium. ☺ im not into any craftman ship really, i just wanted too see if i could make it ☺ looking forward for your upcomming videos☺
man i have to say it, that was a pretty good video, what you just did will inspire other like me to change this world, I also worked with KUKAs , Chirones, Pumas, and my favorite, trumpf laser, few years ago and I know what it feels to work with those machines or just watch them work and then build something like that. good job man
Great work bro, I am a final year mechanical student, when I was in my first year I used to think that I will make such type of machine but our education is very poor student goes to collage just to complete the engineering graduation, and they do not know any think, including me, but we can't do any thing, hope I will be making this type of machine in future, definitely inspiring video,thank you
Amazing! You're the best! After watching countless hours of videos on UA-cam about DYI CNC and how to get it to work, I still had some questions, and you cover it all in an easy understandable way! The SW/HW calibration was driving me nuts because I didn't see anything about it! Thank you! And keep it up!
This was great, I really appreciate the sources where you get this stuff. Also, your enthusiasm is infectious, now I want a CNC mill and I don't know why.
Been watching you for a while now, I had a really great time watching this episode. I'm still in my noob days of CNC, I'm converting a Sieg X2 for my first CNC machine soon, so this low cost, basic and beginner friendly video really connected with me and why I'm so excited about CNC machines.
A massive thank you John for all the hardwork and inspiration. I'm new to DIY CNC and I'm planning to build a CNC Plasma table with a 1200mm x 1200mm work area. These videos have been a huge help and I've just watched this one for the 3rd time, while configuring my Arduino Uno with a CNC Shield V3.0 and 4 Nema 24 motors. I'm also hoping to document the entire process for other noobs like me who have littled to no experience. Should be a good ride I hope :)
I really like that you put parts and other things as links in the description it is something that will keep me coming back to watch your videos because it can be very helpful. thanks!
I'm a boilermaker and I have allways been interested in CNC ,your right that this is an awesome era to be able to do this but it looks a bit over my head,great video,good job man.
I'm building something similar in my mechanical engineering class (as a additional project) but I'm so into this kind of stuff, that I'm definetly going to build another CNC Machine at home.
a common fix for the racking is to drive that axis on both side of the gantry, either with two stepper or a single stepper and a drive shaft at each end
Starting to plan out how I'm going to build one of these for personal projects. Thanks for the videos! It's funny you mention COSI because I live in Columbus and can see the COSI building right now through the window at work!
As usual , you have a fantastic segment on this material. It is so well explained for starters and a great refresher for those with more experience. No matter how often I see this I still am amazed with seeing CNCs control a extruder or machine bit as with remote controls .. and now we use them to control robots on mars ..go figure ! Amazing world we live
Columbus represent! COSI is awesome on days when it's not overrun with rowdy kids that aren't being watched. They have nights that are "adults only" with themes like "puzzles" or "crime investigation" and those are great.
I have a professional flatboard CNC-Cutter at home. To fix the vibrations of your pen you need to build a toolholder that push your pencil to the drawing surface. If you you need fine-adjustment, just add a tension-screw to the top of the springholder. And if you replace the marker for a ballpoint pen you will get even better results, maybe already without spring. If you want to continue on building a drawing machine, you can lift your pen with an electromagnet that pushs up the flexible part of the pen (under the spring).
This is great! I am currently a mechanical engineering student and when I graduate I want to get into machining too because I feel they go hand to hand in the packaging industry (the area I want to work in). I am looking into purchasing an easy item like this to get introduced to cnc equipment!
Excellent video, excellent project and a good alternative to go through a DIY CNC......but what I like most is the enthusiasm given in this video presentation.
Awesome video and project, very nicely explained even for a neophyte like me! +1pts for your perfect language and joviality!... You've just earned an follower!
It has been 1 month short of a year, so I'm not terribly surprised at this. I just went through your bill of materials for the "DIY Cheap Arduino CNC Machine - complete..., Jan 6, 2015" that you recommended from eBay and got a lot of 404 errors, Page not Found. Again, I'm not terribly surprised. It does point out one thing that you might consider for the future, however, is to put enough description of the items that you are referencing that we can find them from another vendor or another source on eBay. I really didn't think that the machine would work for what I want (to cut wood) but the learning experience that you gained from it seemed worth whatever it cost. I thought that I could benefit from it as well. I have the Spark Fun Inventors Kit, that has a robot and Sparkfun's version of the Arduino and shield. That is a great learning experience as well. I want my end result to be a 2' x 3' 2.5-axis cnc router. I really like your videos. I just recently subscribed. Often the instructions on youtube are long and drawn-out, but yours are very concise, you don't say Um, Er, Ah, between every word, well articulated, and it appears that you actually enjoy what you are explaining. The enthusiasm is contagious. Very well done.
As always, a brillant video. So great to see some one excited about work like this. I am watching the video as I unpack new tools that came in the post that I need to continue building my own CNC machine. It was your video on Stepper motors that got me started on building my own CNC. I alway love seeing the email that there is another NYC CNC video to watch.
Trippy...I'm so lost when it comes to all of the programming aspect of industry and gadget tech that I am glad you break things down for us dinosaurs, cool video series! Aloha...Chuck
NYC CNC Yessir, that's the idea I hope with most all of you there machinists, to teach "us ignorants" what a muffler bearing is, he he! I must admit that I did enjoy being "in the know" at least with what a dial gauge and thousandth of an inch was :D
I went to COSI also! I saw the same robotic arm there. I also saw several of the 3D printers a few years ago project and built a reprap (or two). We do live in a fantastic age! Thanks!
Excellent job! I love the diy aspect of this project. I am also currently running a GRBL based home made cnc machine. I love the price and the ease of use of these little devices. Thanks for putting out great videos.
I actually use it for a little bit of everything. Recently I have been doing some v-carving with some 1/8" carbide 45 degree v-bits. The things that can be done with a CNC machine truly are amazing and GRBL has paved the way for a cost effective electronics setup. I really look forward to your future videos on this subject.
Just various kinds of wood so far, I have been thinking about getting some brass to try but I'm not sure about the rigidity of my machine to cut any harder materials.
Hi John, Not exactly my cup of tea but I like the simple progressive approach, I like to learn new stuff, who knows, maybe one day I'll dream arduino. Keep on the great work, you are a pretty good teacher...! Pierre
Thanks for posting this and detailing your work like this. There is a LOT of great info here. I just want to point out that on the linear motion calculation from revolutions, you aren't concerned with diameters and circumferences, since this actually functions as a gear type of drive. The only sensible way to make this "rough" calculation is to take the number of teeth in the timing GEAR (not really a pulley) and compare that to the belt tooth pitch. Since the belt is flexible, this calculation only gives a ball park, and of course the only accurate way to extrapolate is to measure total travel over the maximum number of revolutions available in the travel, and then also to measure each revolution and any other subdivision of steps that you are willing to invest in characterizing the linearity of your machine! This type of drive is only "practical" for a cutting machine that is making cosmetic items or blanks that will need further precision machine work to be used in a machine fit machine part application.
NYC CNC ha! you know what I mean ;) A lot a guys out there just post the (highly edited) successes, and it's obvious they have taken several cuts (movie talk, not machining talk) to get there, it's obvious on yours that this is genuine, you look happy and (sometimes) surprised when things work first time, which I think people appreciate :) Did you ever sort out the wiring on that other project like I suggested by the way?? ;)
Loved your video. I would offer a tip for working with belts. Just multiply the number of teeth by the pitch. If you are using a MXL belt (.080 pitch) and a 20 tooth pulley you will move your axis .08 X 20 = 1.600 inches in one revolution.
first of all. I would like to thank you for sharing this .it's my favourite learning. but I'm a taxi driver. no time to do it myself. but still learning about this lesson.
Watching you do this makes me want to change jobs -- I work in software but I so want to build machines like this. Very inspirational! I bet you could use this as an engraver -- have it do the ipsic cardboard lines on your targets to save tormach time... another machine in the production line.
cool stuff, I working on a CNC welding machine (3 axle) this is how I thought it should run, in the coming weeks I want to build a little demo version. Great inspiring video's
One easy way to solve the rigidity in the x axis would be to add another belt to the back rail on two idlers. Connect the two belts with another shorter belt on the left side between the existing idlers. This will keep extra radial load off the shaft of the stepper and should firm up the back end of the assembly.
Somehow I missed this episode. Hmm....mustve gone by my feed fast. I try to watch every new episode. Oh well. Im here now. Very interested in this stuff. Ive wanted to do this for quite a while. Its time.
NYC CNC Looking forward to it. Do you have an episode 1.5: Building the 2-axis parts? It seemed like a bit of a jump there from making motors turn to measuring accuracy.
Hi John You could very easily add a small RC Servo or even a little Solenoid to the top of the pen that would lift the pen off of the paper during rapid travels. Great video. Willy
Add a solid state laser. Blue light and smoke will drive the STEM kids crazy! You won't need a Z axis, just switch on and off. If you want to keep it cheap and safer power can be very low, write on thermal paper. Way to go taking your time to teach our kids! Scott
Thanks so much for this simple "My First CNC" concept. I was thinking about the Z-axis and it occurred to me that there are two types. The usual z-axis would be analog. The tool travels through a precise range to give a third dimension with the precision of the X and Y. But this setup just isn't rigid enough to put a cutter in (right?) The second type would be digital. It's either up or down. On or off. And for that there's almost nothing complex required. On the pen setup in the video I'd add a cheap $2 servo to the pen holder and attach an arm from it to the pen (probably with a light spring for pressure). Now you can lift the pen off the page almost for free! This would work for me as I just need a blade in there to cut icing for cakes. I need knife-up and knife-down. (Though how to cut vertically without a spinning router type setup into 2mm of icing is a challenge. Any ideas?) I feel a project coming on!
Thanks a lot! I am SOO glad that I found your channel. I want to do some prototyping and was all about to purchase a 3+2 CNC mill for a pretty hefty price as I did not find a decent step through for DIY. Part 1 and 2 of your vid answered all my questions :) Cheers and keep on milling!
I must admit, most of this is still foreign language to me. I'm 74 years old with a high school education. I have become very interested in learning how all this stuff works. I bought an Arduino kit but then I got high centered and have not gone any further. I need to find a place where I can learn and ask questions.

05:18 teleporting fly (yes i realize the video was cut)
haha just saw that. i was sure someone would have noticed that too.
good eye thats funny

Whoa! I used to volunteer at the old COSI! I remember that very machine!!!! So awesome!
I know this is five years old but it's timely for me as I build a CNC plasma cutter using Arduino and GRBL. Thanks John!
Can you please share how you did it ?

these kind of things that makes an engineer breath... awesome!!!!
Then you should go to a machine shop and see the real McCoy. These are just toys.
Then you go to a Machine Shop and see a load of over-specified, expensive scrap metal, churning-out more scrap metal.
Aren't YOU fun.
That's awesome dude. You are right, we do live in a great age.
More power to you.
Amazingly simple yet powerful machine to enter I'm to the world of CNC machining .
I have a professional flatboard CNC-Cutter at home. To fix the vibrations of your pen you need to build a toolholder that push your pencil to the drawing surface. If you you need fine-adjustment, just add a tension-screw to the top of the springholder. And if you replace the marker for a ballpoint pen you will get even better results, maybe already without spring.

For the price, damn sweet build. If i ever have a kid, he's gonna have so many fun toys to mess around/learn with haha

you are the coolest engineer on you tube.
Excellent video, excellent project and a good alternative to go through a DIY CNC......but what I like most is the enthusiasm given in this video presentation.

I want my end result to be a 2' x 3' 2.5-axis cnc router.
I really like your videos. I just recently subscribed. Often the instructions on youtube are long and drawn-out, but yours are very concise, you don't say Um, Er, Ah, between every word, well articulated, and it appears that you actually enjoy what you are explaining. The enthusiasm is contagious. Very well done.
+NYC CNC Thank you for updating that! That was kind of you.
As always, a brillant video. So great to see some one excited about work like this. I am watching the video as I unpack new tools that came in the post that I need to continue building my own CNC machine.
It was your video on Stepper motors that got me started on building my own CNC.
I alway love seeing the email that there is another NYC CNC video to watch.
Trippy...I'm so lost when it comes to all of the programming aspect of industry and gadget tech that I am glad you break things down for us dinosaurs, cool video series!
Aloha...Chuck

Yessir, that's the idea I hope with most all of you there machinists, to teach "us ignorants" what a muffler bearing is, he he!
I must admit that I did enjoy being "in the know" at least with what a dial gauge and thousandth of an inch was :D
I went to COSI also! I saw the same robotic arm there. I also saw several of the 3D printers a few years ago project and built a reprap (or two). We do live in a fantastic age! Thanks!
Excellent job! I love the diy aspect of this project. I am also currently running a GRBL based home made cnc machine. I love the price and the ease of use of these little devices. Thanks for putting out great videos.
I actually use it for a little bit of everything. Recently I have been doing some v-carving with some 1/8" carbide 45 degree v-bits. The things that can be done with a CNC machine truly are amazing and GRBL has paved the way for a cost effective electronics setup. I really look forward to your future videos on this subject.
Just various kinds of wood so far, I have been thinking about getting some brass to try but I'm not sure about the rigidity of my machine to cut any harder materials.
I just created a CNC (learning) playlist and this is the first video in it ! :) Yo are so cool, m8.
Hi John,
Not exactly my cup of tea but I like the simple progressive approach, I like to learn new stuff, who knows, maybe one day I'll dream arduino.
Keep on the great work, you are a pretty good teacher...!
Pierre
I just love people who help others! Thanks a lot man!!
Wow. You have just changed everything for me. Flights are affordable from San Francisco. Thank you. Wow. I hope to make your Open House!
Thanks for posting this and detailing your work like this. There is a LOT of great info here. I just want to point out that on the linear motion calculation from revolutions, you aren't concerned with diameters and circumferences, since this actually functions as a gear type of drive. The only sensible way to make this "rough" calculation is to take the number of teeth in the timing GEAR (not really a pulley) and compare that to the belt tooth pitch. Since the belt is flexible, this calculation only gives a ball park, and of course the only accurate way to extrapolate is to measure total travel over the maximum number of revolutions available in the travel, and then also to measure each revolution and any other subdivision of steps that you are willing to invest in characterizing the linearity of your machine! This type of drive is only "practical" for a cutting machine that is making cosmetic items or blanks that will need further precision machine work to be used in a machine fit machine part application.
another very honest, very detailed, and highly informative video, well done mate! :)
NYC CNC ha! you know what I mean ;)
A lot a guys out there just post the (highly edited) successes, and it's obvious they have taken several cuts (movie talk, not machining talk) to get there, it's obvious on yours that this is genuine, you look happy and (sometimes) surprised when things work first time, which I think people appreciate :)
Did you ever sort out the wiring on that other project like I suggested by the way?? ;)
What do you have holding the non-motorized timing belt pulley? Just a 5 mm axle?
That's what I want to know, too! Spindle bearing on axle for smooth spinning????
Loved your video. I would offer a tip for working with belts. Just multiply the number of teeth by the pitch. If you are using a MXL belt (.080 pitch) and a 20 tooth pulley you will move your axis .08 X 20 = 1.600 inches in one revolution.
first of all. I would like to thank you for sharing this .it's my favourite learning. but I'm a taxi driver. no time to do it myself. but still learning about this lesson.
Watching you do this makes me want to change jobs -- I work in software but I so want to build machines like this. Very inspirational! I bet you could use this as an engraver -- have it do the ipsic cardboard lines on your targets to save tormach time... another machine in the production line.
NYC CNC Great minds... :)
You software guys make good money. You should pick up a CNC kit and start tinkering.
Well done!! Comprehensive production on this- commentary, links for everything! Very impressive and will definitely help me going forward!
You rock dude. I loved the insight on the GCode.
Finishing up my CNC mill now. It's 1,50 X 1,20 meters.
cool stuff, I working on a CNC welding machine (3 axle) this is how I thought it should run, in the coming weeks I want to build a little demo version. Great inspiring video's
One easy way to solve the rigidity in the x axis would be to add another belt to the back rail on two idlers. Connect the two belts with another shorter belt on the left side between the existing idlers. This will keep extra radial load off the shaft of the stepper and should firm up the back end of the assembly.
COSI! What a great institution. Definitely inspired me as well.
You should pursue that dream you had as a kid of doing robotics. Never too late!
Thanks John. I will look for them in the future. Keep your excellent posting.
Somehow I missed this episode. Hmm....mustve gone by my feed fast. I try to watch every new episode. Oh well. Im here now. Very interested in this stuff. Ive wanted to do this for quite a while. Its time.
Awesome man! I think I will give this one a go! You really help a lot by putting the links for everything right there. Thanks so much for the video!
thank you
your videos just made me interest in CNC machinery
respect from algeria
Wow! Just wow! Can't wait for more now.
love the simplicity of that belt tensioner
This is awesome! I suggested this for the arduino blog.
NYC CNC Looking forward to it. Do you have an episode 1.5: Building the 2-axis parts? It seemed like a bit of a jump there from making motors turn to measuring accuracy.
Hi John, thanks for the video, it has inspired me to build my own CNC machine with great success!! I mailed you some pics of my build
Hi John
You could very easily add a small RC Servo or even a little Solenoid to the top of the pen that would lift the pen off of the paper during rapid travels. Great video.
Willy
FELICITACIONES, SE VEMOS EN LIMA PERU. ERES UNA GRAN MOTIVACION VIENTO TUS VIDEOS. UN ABRAZO
This was a fantastic video, really shows how to setup and build a CNC. Really cool!
sweet demonstration! Steppers are awesome to mess around with!
Add a solid state laser. Blue light and smoke will drive the STEM kids crazy! You won't need a Z axis, just switch on and off.
If you want to keep it cheap and safer power can be very low, write on thermal paper.
Way to go taking your time to teach our kids!
Scott
Since there is some play in the system, will it be accurate enough for photo and even cad drawing engravings?
Awesome stuff. Cant wait for the larger cutting version.........
This is a brilliant idea for a Laser Diode Engraving Machine. Thank you very much
Love It Man!......Clear Cut & Concise!
Excellent series John! Keep up the great work.
Great video and thanks for your hard work.
Great video. Worth sharing to a very wide audience.
Thanks so much for this simple "My First CNC" concept.
I was thinking about the Z-axis and it occurred to me that there are two types.
The usual z-axis would be analog. The tool travels through a precise range to give a third dimension with the precision of the X and Y. But this setup just isn't rigid enough to put a cutter in (right?)
The second type would be digital. It's either up or down. On or off. And for that there's almost nothing complex required. On the pen setup in the video I'd add a cheap $2 servo to the pen holder and attach an arm from it to the pen (probably with a light spring for pressure). Now you can lift the pen off the page almost for free!
This would work for me as I just need a blade in there to cut icing for cakes. I need knife-up and knife-down. (Though how to cut vertically without a spinning router type setup into 2mm of icing is a challenge. Any ideas?)
I feel a project coming on!
Thanks a lot!
I am SOO glad that I found your channel.
I want to do some prototyping and was all about to purchase a 3+2 CNC mill for a pretty hefty price as I did not find a decent step through for DIY.
Part 1 and 2 of your vid answered all my questions :)
Cheers and keep on milling!
