Just wanted to let you know how much you have inspired and taught me. Currently building my own desktop cnc mill, with dedicated raspberry pi, screen, and keyboard; am so fucking excited. Would have never thought about this project if I hadn't watched your vids; thanks.
Its great seeing you extend this passion for experimenting to making kits for people to buy. I love how you take the experimental phase and make a usable product. Your business model is definitely a good one if you never want to "work" a day in your life. :-) Rather, doing what you enjoy.
Thanks for the great video series and congrats on making it to over 51,000 subscribers SO FAR! While this may be a simpler, less-perfect design for a gantry-style CNC platform, it does offer beginners the opportunity to learn and apply some core fundamentals before tackling more robust, more accurate, more complicated, and way more expensive platforms. I felt it was important to support your time and efforts by springing for one of your pre-milled aluminum angle sets. For those of us without access to the proper tools, it would be unlikely we could participate in this learning experience beyond the most theoretical portions. As a definite fan of your work and someone hoping to complete a variation of your updated arduino CNC example, I'm really hoping enough folks will also consider supporting your z-axis kit such that it can become available for purchase again. Right now I feel a bit stuck in limbo not knowing whether to eat my expenses to-date (and hope I can apply those purchases elsewhere) or wait until the z-axis openly offered in the video, in the description, and on the Saunder's site becomes a purchasable item such that I can complete the project and leverage the knowledge, if not the basic platform, for a more sophisticated version. Thanks again.
Hi John, That Z axis pen activator is pretty cool! I liked watching the close up where that arm came around and pushed the pen down. Nice design on the pen holder too! Looking forward to seeing the bigger, sturdier machine too. Thanks for the video! -mike
John, when you get further on your larger machine with the ball screws you were showing, make sure you use a TinyG to get the best experience. TinyG has all the modern features that Grbl doesn't have so it's worth it.
A great video John, your Z axis solution was simple but very elegant engineering, nicely done. I'm really looking forward to seeing what you will come up with for those linear rails and ball screws. It looks like it has the right bones for a platform that could be used for all manner of purposes and I suspect I will have a "follow along" build coming up in my near future!
John, this is a great video! I can not wait to see what you have next to show. Thanks for showing ChiliPeppr! This is just great! Love my GRBL thanks to you! :)
Can't help comparing this to the pen plotters we used so long ago. The ball screw will certainly reduce jitter on the x axis. Perhaps when you're ready to do a large format plotter, we can see you engineer moving the paper in the y axis. I seem to remember instead of a plunger for pen pressure, they used a tilt up pen carrier that used it's own weight to keep pen on paper. Very informative vid though.
Awesome video! And I can't wait for your next version of this machine!! I hope you'll be able to provide a full parts/component list for it as I'm sure folks will want to build one too. Mahalo for sharing your knowledge!
MORE LIKE THIS! Great video. Thanks. Liked and shared! I greatly appreciate not only the enthusiastic videos with high production standards, but also the links and other added info in the video description.
Been waiting for this video checking every day since your last video on this project sometimes more than once a day lol. Now I begin my excruciating wait for the next one, great work btw and thank you for sharing it!
iwas initially thinking about building myself a CNC machine to mill PCBs... but i really like the idea of building a smaller cheaper one just to trace out the pcb and then etch it! excellent!
It might be cool to see if you could use a small pen type micro-grinder instead of the felt pen with a slow movement or multiple passes to do some engraving.
Note that the gshield isn't the only way to do this. You can get a 'Arduino CNC Shield V3 + 4PCS A4988' from amazon that does the same thing - I tried it tonight (after receiving the parts from China this week) and it sure seems to work quite well.
NYC CNC Exactly that one. I purchased from the same vendor and received it in a little more than two weeks. Uploaded grbl to it and have everything hooked up - just no CNC table yet :) Oh, one more thing, chilipeppr with the serial driver is THE BOMB! Thanks a million for that.
Hi John Great video think you have persuaded me to dip my toe into the CNC world. Think I will have to have a go at making one. Many thanks Mark Over the Pond in the UK
+Paul Henderson you should take a look at this one Paul Henderson, I am currently making this CNC on my school as science project, we've almost finished it, we are only currently waiting for the stepper motor's to ship in. :D
Resonance. [Being the explanation for why smoothness:feedrate is a nonlinear relationship.] If you keep looking you will probably find several "bands" of feed rate frequency that are noisy/quiet, alternating. Anyway, should have acceleration control on all of this, so it doesn't run at one fixed freq half the time, until it maxes out to the feed rate, which you would chose as one of the less resonant bands...
Thank you for all of your positive energy. I like your "why not" morals. keep up the good work. And I am looking forward to that more awesome and stronger design you have in mind.
Thank you. Very informative video. Thanks for sharing all the details, which makes it possible/easier for your viewers to make one of these. Keep this good stuff coming. I'm looking forward to your next CNC machine with the ball screws and linear rails. Thanks again:)
As a woodworker with no programming or machining experience I would LOVE a shop CNC. However I dont have $800-$2000 to spend on a intro machine. Watching this series makes me hope that one day a cheap machine like this (or this one) will be available to build for a beginner. Any dirt cheap machines that dont require the math and computer knowledge?
Great vid John!! and good timing to. I'm working on a small CNC project as well, just figuring out if i need to move to a GSheild/GRBLsheild or if a RAMPS board will do the trick for some NEMA 17s. Nice find on Chilippr as well.
it is not so surprising that those linear bearing are a bit wobbly, they are supposed to be used in pairs, to some extend that also goes for the fancier linear rails, they are a lot stronger in the up-down side-to-side direction that in "twisting"
@NYC CNC, have you tried lowering the speed around corners? Check the GRBL wiki on github. The configurations file as value '$11=0.020 (junction deviation, mm)' as default. This is the junction speed, lower values make the algorithm slow down when cornering. This should solve your pen corner problems.
That's a really cool design John, nice work. Love the lever operated pen design. The little Roland machines (plotters / vinyl cutter) use a electromagnet solenoid. But yours is way cooler. Cheers, Aaron
Nice to see this project comes back on. I am building a system base on the first video using ball screws and rails( these things really make it's much simpler to build) for a month now, but mine requires 3 parallel independent axis, still having trouble to control them probably with adruino and drivers using code, any suggestions. Another thing is that how can I set the intial positions for these axis, they keep hitting the limit, i plan to use endstop switchs, is it ok or any ideal better. Thanks. Ps: wish to discuss more about this if u are free.
Looks good! Can I make a suggestion? As an alternative to the steppermotor Z construction you can also use a electrosolenoid. For example one with a travel of 20mm and a force of max 10newton. If you use that combined with a spring that has a compression force of for example 7 to 8 newton you can easily operate the pen's position. (less parts, and on/off operation) Not to be negative about your idea, it looks good and love the creativity with the springs.
Thanks for videos! I built the Z axis design you made and love how simple and effective it is but got a quick question. When the motor goes to the pen down position, how do you get to hold that position? My work so far has the zaxis stepper moving to the pen pressing down, but once the position of the stepper is achieved, the stepper motor does not hold the position. Maybe another way to say it is that the stepper motor travels the steps it is programmed, but once it is there the motor doesn't stay charged to maintain the position and the pen defaults back up. Thank u!
wow new gcode sender chilipeppr,must try it, by the way can you make some video regarding the kill switch and wiring it using the grblshield (A0 to A5 pin in the arduino uno),thanks can't wait for that.
Thanks dude,actually i made one base on your video 1&2 and follow all your steps, without your post i can't make my own cnc.Currently am testing it using pen and some calibration.Again THANK YOU.
Thats very nice. I would like to know if you could achieve higher speeds with that. Iwant to build a machine like that but I have other application in mind which wouldnt require much drawing precision but instead speed. Is that possible with this setup? Something around 15cm/s?
Nice little machine. I love your spring loaded pen solution. Another neat option for it would be a diode laser to build a simple laser cutter. Chilipeppr already has laser cutting built in. I look forward to seeing what machine you've got coming next, I'm building a linear-rail/ballscrew micro-mill right now to house a high speed spindle when the big CNC mill is too slow.
No existing design for mine, but it's not very unique either, just a standard X-Y-Z axis made out of hunks of aluminum with linear rails bolted to it. Are you on the Onshape beta? If not you should be! Its the future. My micro-mill is a public document.
I'm shocked you aren't into Onshape yet. I had a friend sign up and he got in within minutes. Sure the invite isn't in your spam filter? You are NYCCNC!!! They should be paying you to use it.
I am making one to solder a board, but what happens when it misses a step. The stepper motors dont know where they there. Dont you need an encoder? If you so do you know how I can hook it up to the arduino? I love your videos! Keep them coming!
Thanks for the great videos. I am very interested in making this unit and getting started with an Arduino CNC type machine. I am just a little confused on all? the different softwares that are needed. Could you list the different softwares that are needed start to finish? Thanks
Great Idea bro. I am going to do it. I also have some doubt. In first I thought of using Inkspace software for Gcoding and linking it with processing software for plotting. 1)Can I use universal Gcode sender (gctrl) and Processing software simultaneously. 2)I am going to use a motor shield L293D , will it work with the methods you mentioned. 3)How to find the steps per revolution. Please help me bro
4 days and I'm ordering all the parts. Did you know your parts in the US are cheap but I looked on amazon for the parts you say and they are the fraction of the price. Plus can you do a video on how to use the alternative to the sheild plz as that £80 over hear and the alternative is like £10
have you ever checked out Openbuilds.com it is along the lines of what you have here small scale CNC's I'm in process of building a 2 x 4 CNC for cutting smaller stuff instead of putting them on the large 4 x 8 table
Just watched your video, DIY Arduino CNC: Axis upgrade & Chilipeppr! Widget34. Was wondering if you sell this little kit? Or are you planning on coming out with a improved model? Thanks. Woody
could this work as a desktop cnc to mill small metal parts? been looking for a cheap way to do things, think I would make this a little more ridged tho .
Great video. I would like to purchase/build one of these for the very specific purpose of inlaying intricate designs into wood. So I was wondering, could this be fitted with a Dremel tool for woodworking purposes? Thanks in advance.
just a quick question how to get that speed and more on the x and y axis and to get more speed what is the best way for the table to make a stepper motor moves the table on x or to make the z holder move on a rail thanks to any one can answer me
Hello im justing wondering on how 3d objects work toward doing a milling project, how you make the z axis move down as it completes the G code is it the same way as 2d objects, if so how do you let it to only go down a little at a time when using a drill bit
what type of controller boards/ drivers/ break out boards would you recommend for a plasma cutting table?....and also what would you recommend or a thc?
I am a high school teacher try to build this machine with my students. Could someone provide me a list of the bolts required for assembly. I know that they are metric, but I am not sure of the size and thread type. Thanks
Hi John, love your videos! All very informative, well put together, and just plain cool! We share many common interests! Just subscribed today, BTW first channel I have subscribed to! :] I built a small CNC machine like it sounds like you are planning on building, with supported ways, etc. I also designed my own Arduino based GRBL controller PCB, essentially a cross between GRBLshield and TinyG, where it's an all in one board solution, with female headers for four SD8825 based step motor driver carriers and Atmega chip, so you can easily remove/replace them if needed. The intention was for it to be very versatile. Plus a function to drive a BLDC spindle through a standard R/C ESC if you're in to that sort of thing! Also I've been using the cheap Ebay Bluetooth modules to "talk" to it as well, so I can locate the PC away from all the flyin' chips! I can send you one for free if you think you have time to try it out, I need another Beta tester, besides myself :) Cheers, and keep up the great work!
NYC CNC Yes it has good ole GRBL loaded on the Atmega MCU....imagine the Arduino Uno and GRBLshield combined on one board, similar to TinyG in that aspect, but with removable/replaceable step drivers, microcontrollers, and just a slightly modified GRBL (just had to remap some of the pins). I've somewhat planned to offer it as a DIY PCB kit eventually. The price point would be similar to Grblshield with out the need to buy the Arduino separately. However folks would have to solder them up (all through hole, so very easy soldering) themselves! I don't have time myself to solder them, but I purchased a small quantity of all the components, and had a small production run of the PCB's made. So far I have tested a couple, and they have been working great on my little router! Sure be nice to see them for sale on the SMW website, perfect complement to the DIY Arduino CNC parts... hehe :)
NYC CNC I have not tried it, but I imagine so! It would be a bit less elegant. I suppose you could use the female pin headers that typically hold the SD8825 style stepper drivers, and jumper the signals to any step driver of your choice (provided it is a Step/Direction based driver). The drivers would of course need a power supply as well. I may give it a shot when I get a chance, I have some larger drivers and steppers I could experiment with. Cheers!
i made my z axis like you show but once the metal rod touches the spring it bounces back. it wont hold the pen down. any idea on how can I solve that? thanks.
I like your dual-spring pen solution too! Chili-P looks pretty cool. ...other than spelling chile wrong. :) I see it's a web site. Does it continue to run if your internet has decides to -take a crap- _stop working_ in the middle of a program?
***** Go ahead and give it a try to save it offline. ChiliPeppr is a Javascript/HTML app so it may work for you, but I have found in my experience saving it offline is not very workable.
Im just wondering as to the choice to use a stepper to lower the pen, and not a solenoid? Cheeper, simpler, and more reliable. Is the stepper to be used later for other Implements?
With the stepper, you can adjust the pressure on that top spring. Allows a little more fudge factor when using different pens to adjust the pressure. Cheap source of those springs... old spiral bound notebooks.
grbl will directly control a stepper for the z-axis (and so will the driver boards). If you wanted to use a solenoid you'll have get a driver for it and configure grbl for turning it on/off (it may already support that for laser cutters)
NYC CNC A stepper has a few inherent problems. It needs a third axis's controller.With out an encoder or limit switch it will eventual forget home. If this will eventually be used for a light milling machine of sorts, then by all means this is ideal. If this is going to sold as a kit as is. You can simplify the hard wear reduce and sail price, by using a solenoid. controlled by a single relay, a solid state one will allow PWM directly out of the ardino for presser control.
+NYC CNC Save money and use a parallel belt drive and cross over belt drive, or idler pulleys and one longer belt. Great project and outstanding instruction. Thanks
you should check out open builds website, they sell aluminum extrusions called "V Rails" that are perfect for small CNC's I am currently in the process of putting one together.
+NYC CNC I have enjoyed watching your videos on DIY CNC's. They have helped me along in my own build. I do wood work instead of metal but your info still applies. Thanks for taking the time to make these videos.
Just wanted to let you know how much you have inspired and taught me. Currently building my own desktop cnc mill, with dedicated raspberry pi, screen, and keyboard; am so fucking excited.
Would have never thought about this project if I hadn't watched your vids; thanks.

Thanks for the great video series and congrats on making it to over 51,000 subscribers SO FAR! While this may be a simpler, less-perfect design for a gantry-style CNC platform, it does offer beginners the opportunity to learn and apply some core fundamentals before tackling more robust, more accurate, more complicated, and way more expensive platforms. I felt it was important to support your time and efforts by springing for one of your pre-milled aluminum angle sets. For those of us without access to the proper tools, it would be unlikely we could participate in this learning experience beyond the most theoretical portions.
As a definite fan of your work and someone hoping to complete a variation of your updated arduino CNC example, I'm really hoping enough folks will also consider supporting your z-axis kit such that it can become available for purchase again. Right now I feel a bit stuck in limbo not knowing whether to eat my expenses to-date (and hope I can apply those purchases elsewhere) or wait until the z-axis openly offered in the video, in the description, and on the Saunder's site becomes a purchasable item such that I can complete the project and leverage the knowledge, if not the basic platform, for a more sophisticated version.
Thanks again.
Awesome videos, John! I find your stuff much easier to understand than most. I am a raw beginner. Keep up the great work!
Thanks John! I'm looking forward to the next project build video with the more rigid version of this machine! Very inspiring.
Watching your arduino series gives me some ideas about automating some lathe operations like making tapers on my old Atlas.

Hi John,
That Z axis pen activator is pretty cool! I liked watching the close up where that arm came around and pushed the pen down. Nice design on the pen holder too! Looking forward to seeing the bigger, sturdier machine too. Thanks for the video!

Nicely done John! I am excited to see what the next machine is, but I love that you're tinkering with Arduino again. Keep up the great videos!
John, when you get further on your larger machine with the ball screws you were showing, make sure you use a TinyG to get the best experience. TinyG has all the modern features that Grbl doesn't have so it's worth it.

my X axis wobbled too, even with 20mm linear rails, so i just added a second stepper on the other side. works now.
Can't help comparing this to the pen plotters we used so long ago. The ball screw will certainly reduce jitter on the x axis. Perhaps when you're ready to do a large format plotter, we can see you engineer moving the paper in the y axis. I seem to remember instead of a plunger for pen pressure, they used a tilt up pen carrier that used it's own weight to keep pen on paper. Very informative vid though.
Awesome video! And I can't wait for your next version of this machine!! I hope you'll be able to provide a full parts/component list for it as I'm sure folks will want to build one too. Mahalo for sharing your knowledge!

For the Z axis you could use a servo. They are easy to control (PWM) and cost only fraction of a stepper.
I'm confused, where are the videos showing this built? I cannot find them
Make the top plate the marker mounts to wider. and put two markers in there. have the stepper for the opposite way and you just made a tool change!!
I don't quite understand do you mean mount the steppers do they're offset from each other rather than parallel?
Where's the update?!?!?! Can't wait to see the final version in action (hopefully making $).
Brilliant description and demonstration
Can't wait for the proper CNC machine!
Nice ! I'm looking forward to seeing your next machine !!!
Following along on this one. Chilipepper looks like a step up from UGCS.
It might be cool to see if you could use a small pen type micro-grinder instead of the felt pen with a slow movement or multiple passes to do some engraving.
It's a good time to live - couldn't agree with you more!!! Well done can't wait for the next one!!!

What about converting this into a 3D printer with a print pen used? Would be really neat
+James Lavender You would need an actual Z axis for 3D printing. May as well just get an Open Builds bot, and throw a E3D V6 extruder.
This makes a perfect project for school!

how to get that speed and more on the x and y axis
and to get more speed what is the best way for the table
to make a stepper motor moves the table on x
or to make the z holder move on a rail
thanks to any one can answer me
@NYCCNC Did you eve actually build the upgraded version of this you talked about at the end of the video?
i mean to say that can i run instead of processing 3.3.6 ut with some other software compactible with arduino uno based sys.
Hello im justing wondering on how 3d objects work toward doing a milling project, how you make the z axis move down as it completes the G code is it the same way as 2d objects, if so how do you let it to only go down a little at a time when using a drill bit
what type of controller boards/ drivers/ break out boards would you recommend for a plasma cutting table?....and also what would you recommend or a thc?
Are you guys still selling the z-axis kit? If so, can you send me the link.
PEN SOLUTION SI AWESOME
awsome vid i love watching nyc cnc
thx for your video. i do have a question ,can i engrave any picture if i scan it on my computer...
I am a high school teacher try to build this machine with my students. Could someone provide me a list of the bolts required for assembly. I know that they are metric, but I am not sure of the size and thread type. Thanks
Please let me know how to configure and upload the grbl file for my core xy drawing machine? I also use an uno with Adriano.
If my machine hits the limit switch it stops. So far so good. But i need to remove him manualy if he hits it is there a solution for?
Hi John, love your videos! All very informative, well put together, and just plain cool! We share many common interests!
Just subscribed today, BTW first channel I have subscribed to! :]
I built a small CNC machine like it sounds like you are planning on building, with supported ways, etc. I also designed my own Arduino based GRBL controller PCB, essentially a cross between GRBLshield and TinyG, where it's an all in one board solution, with female headers for four SD8825 based step motor driver carriers and Atmega chip, so you can easily remove/replace them if needed. The intention was for it to be very versatile. Plus a function to drive a BLDC spindle through a standard R/C ESC if you're in to that sort of thing! Also I've been using the cheap Ebay Bluetooth modules to "talk" to it as well, so I can locate the PC away from all the flyin' chips!
I can send you one for free if you think you have time to try it out, I need another Beta tester, besides myself :)
Cheers, and keep up the great work!

Yes it has good ole GRBL loaded on the Atmega MCU....imagine the Arduino Uno and GRBLshield combined on one board, similar to TinyG in that aspect, but with removable/replaceable step drivers, microcontrollers, and just a slightly modified GRBL (just had to remap some of the pins). I've somewhat planned to offer it as a DIY PCB kit eventually. The price point would be similar to Grblshield with out the need to buy the Arduino separately. However folks would have to solder them up (all through hole, so very easy soldering) themselves! I don't have time myself to solder them, but I purchased a small quantity of all the components, and had a small production run of the PCB's made. So far I have tested a couple, and they have been working great on my little router! Sure be nice to see them for sale on the SMW website, perfect complement to the DIY Arduino CNC parts... hehe :)

I have not tried it, but I imagine so! It would be a bit less elegant. I suppose you could use the female pin headers that typically hold the SD8825 style stepper drivers, and jumper the signals to any step driver of your choice (provided it is a Step/Direction based driver). The drivers would of course need a power supply as well. I may give it a shot when I get a chance, I have some larger drivers and steppers I could experiment with.
Cheers!
Love your videos!
Is this design capable of plotting a circle comparable to a compass drawn one?
Keep up the good work
What stepper motor does tormach use?
Where did you happen to buy those metal screws and linear sliders? (You don't say in the description)
NYC CNC No, I mean the hardened screws and new sliders your gonna use for the "upcoming" project. The ones you briefly show at 13:15 and 13:25
i made my z axis like you show but once the metal rod touches the spring it bounces back. it wont hold the pen down. any idea on how can I solve that? thanks.
+Molly Hou are you married?
I like your dual-spring pen solution too!
Chili-P looks pretty cool. ...other than spelling chile wrong. :)
I see it's a web site. Does it continue to run if your internet has decides to -take a crap- _stop working_ in the middle of a program?
Hirudin Yes, ChiliPeppr keeps running fine if your internet goes down. It actually all just runs local once it's in your browser window.
Ah good, thanks!
***** Go ahead and give it a try to save it offline. ChiliPeppr is a Javascript/HTML app so it may work for you, but I have found in my experience saving it offline is not very workable.
ChiliPeppr is not Java, so there is no jar file. It's Javascript/HTML.
Im just wondering as to the choice to use a stepper to lower the pen, and not a solenoid? Cheeper, simpler, and more reliable. Is the stepper to be used later for other Implements?
With the stepper, you can adjust the pressure on that top spring. Allows a little more fudge factor when using different pens to adjust the pressure. Cheap source of those springs... old spiral bound notebooks.
grbl will directly control a stepper for the z-axis (and so will the driver boards). If you wanted to use a solenoid you'll have get a driver for it and configure grbl for turning it on/off (it may already support that for laser cutters)
NYC CNC A stepper has a few inherent problems. It needs a third axis's controller.With out an encoder or limit switch it will eventual forget home.
If this will eventually be used for a light milling machine of sorts, then by all means this is ideal.
If this is going to sold as a kit as is. You can simplify the hard wear reduce and sail price, by using a solenoid. controlled by a single relay, a solid state one will allow PWM directly out of the ardino for presser control.
Where I can get the Z-axis?
where can I buy the parts?
would a stepper motor on the other side for the y axis help in the stability of the z axis ?
+NYC CNC Save money and use a parallel belt drive and cross over belt drive, or idler pulleys and one longer belt. Great project and outstanding instruction. Thanks
where is the best place to buy smooth rods at?
you should check out open builds website, they sell aluminum extrusions called "V Rails" that are perfect for small CNC's I am currently in the process of putting one together.
+NYC CNC I have enjoyed watching your videos on DIY CNC's. They have helped me along in my own build. I do wood work instead of metal but your info still applies. Thanks for taking the time to make these videos.
Where is the code for the Arduino?
very useful. thank you!
Great video. Thanks for posting and sharing... :-)
