As always, you've shown an extra step or two than most others demoing their machines and its just the steps needed to help me on my way. Thanks so much.
Instant subscribe. You did an excellent presentation of the information I was looking for. I would like to do foam cut outs for lost foam casting, nothing serious, hobby stuff and this video helped. VERY happy I stumbled across this! THANKS!
Excellent video, well documented (always important), and very clear in instruction. Thanks so much.
nice episode. I've spent the week machining small aluminum parts with my cnc machine. thanks for mentioning jscut, i will give it a try.
I wanted to know about cnc and you have done that very well..thank you, Bill
The Ben Heck Show your knowledge in all fields is extra-ordinary ....!!!!Thumbs UP!!!from India...!!
Your comment at 18:45 is exactly why I am watching this video right now. I am currently building a basic CNC Router to make the parts for more advanced one.
I'm not thinking of building a 3D printer first to print parts for a CNC milling machine too... That could become a never ending circle haha
VoltageLP You are absolutely right! I've built several CNC machines and mostly I use them for making parts for better CNC machines. This has been going on for over two years now with no end in sight. But what the heck... it keeps me out of trouble.
CNCholism )
When setting the zero on professional machines we always used a piece of paper as a feeler gauge between the Bit and the workpiece, then subtracted the paper thickness manually in the coding.
Also we had an x y z jog wheel. Essentially a rotary encoder to control movement on the selected axis (which you selected by pushing x y or z button) and you also pressed 1 x 10x or 100x button to control the speed of movement per revolution of the jog wheel.
That would make a great project
Wow this show is very polished, go prime time already! And that intro...vry cool.
Very informative introduction. Trying to gather enough info and screw up my nerve to build one! Thanks much!
can you completely explain the raspberry electrical (all connections) connection for a CNC built with your hands step by step.
I love that he tells us not to move it and then spends 5 minutes CONSTANTLY moving it.
***** He said not to move it too quickly.
Very clear and instructive, thank you !
I wanted to add a solution to moving the axis of the CNC. On a machine I built back in the 90s, I used a DPST switch at each motor. Each pole of the switch would connect to each winding. You only need to connect the switch to one side of the winding. When you have to move the machine, just flip the switch and move all you want. In later builds, I would put relays at the control board to effectively take the motor our of the circuit. I would then connect the relays to the supply power. So when the machine was on, the motors were connected or armed. When the machine was off, it would take the motors our of the circuit and protect the driver.
There was a discussion about using a diode but it would not work. Because steppers are unique, they can send reverse voltage to perform a higher resolution. Putting a diode would limit voltage only going in one direction.
+Bob Roszkowski if you give me your email ,that i tell you.
Hi ben, first of all thank you for this very informative video. I'm new to CNC and just got my unit. its a china D.I.Y. 3018 machine... I would like to follow your steps in creating a design, that Adobe illustrator, jscut... but instead of going to chillipeppr can i use the grbl 0.9 to run the machine? the grbl 0.9 came with the unit.
thank you ben. hope to hear from you soon
This is the best video I have seen this guy do. He's a scientist and teacher. A humorous entertainer he is not. I am glad he skipped the comedy routine in this video. There's been so much suffering already.
+Jeff Beck I agree! I met him once and his social skill set is lacking but I watch him because he is a scientist that can teach.
On my custom built R2D2, I have the same concern of pushing him and generating power that overheats his foot driver board. The maker of the driver board recommends putting a diode circuit around the power switch back to the battery. Perhaps one could do something similar here. Of course, a rechargable battery would need to be added.
Awesome! Always wanted to learn about CNC!
This was Fantastic! I will definitely be subbing. Now I am eager to get a machine.
hi dear, we can offer the same machine, wahtsapp +8615508689532
Love the Epilog in the background
Ben thank you for your presence on you tube. keep up the good work.
I would like to build a cnc plotter that is very fast and accurate. What do i need to consider in terms of the electronics. I do not intend to spend alot of money and it is going to be a large one (paper size minimum is about 29 inches). What advice do you have for me if any?
It's a very nice project that worth to build !!
This is very much a introduction to CNC machining, with the use of foam as the material a lot of the hard settings to get right did matter as foam is very soft.
When you start to mill wood, PCB's and metal. etc things get a lot lot harder, spindle/tool rotation speed, feed rate how fast you move the tool through the material become very hard to calculate and are related to each other, setting rotation speed effects the feedrate altermately to carry heat away from the tool with the chips of material being removed. This is something i didnt think about when i purchased a CNC machine, it takes some time to build a database of information on your tools and materials to get the cutting speeds right, getting them wrong can be expensive as you will start to snap cutting bits by over heating or over stressing them. I did this
a lot when first experimenting.
Could you build a sound cancellation cabinet for this? Take the audio from the CNC mill running, reverse it's phase, and then output that to speakers in the cabinet to destroy most of the sound waves?
Very informative, thanks!
Hi Ben, i'd like to know if there is an Open Source CNC machine just like prusa i3, plus if they have kits to build too.
What program do you do the original drawing? What is the order of the programs you use from start to finish?
Yo ben, don't know if you'd be interested in coming back to this topic of CNC machines, but do you think you could do a step-by-step or general overview of how to build a cnc router?
Hello, i have made a cnc frame 40 x 60 cm wide with v slot aluminium profiles, have mounted 16mm rods and bearings and a router trimmer. Wanted to ask: for this cnc frame size and 16mm rods and bearings: 1. what thickness of lead screws should i use (would 8mm lead screws work well) and 2. which is the smallest stepper motor that i can use ?
+The Ben Heck Show Couldn't you use diodes to prevent the current from the motors going to the boards?
A question to around 4:15:
In the H-Bridge to the stepper motor are Mosfets build in aren't they?
So would the current short out the motor itself though the flyback diodes in the FET and dont effect the circuit? Or am I thinking wrong?
Btw: Thanks for the good videos =)
Hi ben would you please tell me what type of spindle is best to cut steel for a sturdy diy cnc
I was thinking making one on my own but don't know best speeds and hp it needs to be.
Thanks before hand
+The Ben Heck Show , just wanted to say I enjoy your show and find it entertaining. I do have some questions, is there a reason you used foam for this demonstration?, what the toughest material this machine could mill? Also when you were talking about the differences between the machines that had the base move vs the movable gantry I was wondering I what you meant by the setup shown being simpler. Thank you for your time making these videos and for your response, be well.
Ben, I'm looking for something similar to cut frames out of carbon fiber for R/C multirotor assembly. Is this a good idea or do you suggest something better?
Great video!
Schottky Diode premade boards for 4 wire stepper motors are available on ebay very cheaply for a few dollars that will provide back current protection blowing up the driver boards. Highly recommend.
At 6:22 the annotation comes up saying "...this can gain you accuracy though."
Strictly speaking, wouldn't adding the threaded rod only help you to gain resolution not accuracy?
Great easy explanation
Why not use a diode or a capacitor to prevent generated current from going back to the ICs? You're not controlling your motors by back EMF as in BLDCs anyway
Hi!
Iv got a question about building 4axis CNC on 1200x1200mm measurement. What is the best stepper motors for this size? Working with alloy or wood materials. Thank you If you will help me with this project problem!
Hello! I would like to know what type of cnc machine I would need to count piendra de mermol and obtain a 3D result, Thank you!!
What is the name of the white material stock Ben loves to use for CNC milling/routing?
I can't for the life of me find out in which episode does he mention it.
Thanks
Hi Ben,
Do you know if it would be possible to make a machine that could both be a 3D printer and a CNC router, since it would just be a manner of of changing the hotend with a dremel.
You are awesome. I wish I watched this film before I ordered my machine. Now is too late.
I have a German made CNC machine that accept only .PLT files. Is not loading other types of files format. This is making me crazy because are so many software options there and I cannot use them. I only want to engrave small flat items.
Is there any way that my machine can use other software programs? Like the ones in this film?
Thank you and thank you again for this videos.
Love it the Dutch way. Freelance knowledge!!
The noise cancelling headphones made me chuckle :) ... Quick question. How hard would it be to add water cooling to a machine like this? (In order to cut things like granite.)
Do you know how i can wire a arduino cnc? Which stepper motors, drivers should i use? Do i need a shield?
which control system is better for cnc router between SIEMENS and SYNTEC ???
i heard syntec is famous and its good and i have no idea about SIEMENS .
How expensive will making one of these be? And would it still be usefull if it was a little bit smaller? What motors do I need, will the cheap DealExtreme motors suffice?
Someone please answer.
"Incredible acting" - love it!
Dave P Exactly my thoughts! xD
a very impressive vid ben. one suggestion. why not have some sort of ON/ OFF switch on each power line to each motor. so when your about to move the motor you simply flick the switch to OPEN CIRCUIT. stops any power/ current feeback .
"only move the motors manually slowly", cannot this be solved using a simple diode that short circuit the motor reverse current, like in many other systems?
i have a merc stealth keyboard and i would love to get the same layout but with mechanical switches can you design one from scratch?
Hopefully someone could answer my question: is it possible to use a 3d scanner to digitize a simple object and then reproduce it with a cnc machine?
a small CNC machine like the one in this video can also act as a 3d printer with a few tweaks, basically they are both 3-axis machines. I think I will aim for a versatile object like this if i ever going to build one (obviously I don't want to buy a ready-made one cause it would not fit my needs)
He makes a fantastic point about moving the gantry quickly causing back EMF from the motors back to the board. Those boards may not be protected for that type of usage. It's a good point especially when transporting a CNC and the thing is flying around in the
back seat of a car, and you arrive with a fried microcontroller board. But who knows. Some of those boards may have protection for that. But still. Why chance it.
+Jeff Since Ben was very clear about that subject, I can only assume you wanted to post in order to co-opt his intelligence. A point further buttressed by your use of Electromotive Force (EMF). The potential voltage generated by manual movement is only half of the concern. There are amperes to consider.
Very interesting. But I'm looking forward for the next Old-Computer-in-portable-style project. How about a C=64 portable? :D
very good video. thanks
4:17 arent there PN diodes to prevent that?
Can I operate the program of the CNC and design program with a Mac computer, be it adesktop or laptop?
I would like to know folks opinion on the drive system for the Inventables X Carve. It is a rubber belt similar to what was in this video I’ve heard criticisms of this belt drive system. I was considering buying X Carve but became concerned after hearing some reviews. Is it still worth buying? I know it depends on what I will be using it for. I’m a hobbyist and may give away or sell a few of my creations that aren’t super detailed.
Excellent tutorial.
Can these machines make cribbage boards?
Hi Mr. Heck! This video is positively great! I'm putting together my very first CNC machine from scratch so you can imagine how helpful all this info has been. Could you tell me what computer program you used first to do the drawing of your name and the rectangular outline? Does it matter which program you use to create your design? Many thanks for your excellent work. Definitely liked and subscribed.
instablaster...
The machine follows the pattern from the center of the bit correct? So do you ever have to take into account the size of the bit itself for precise slots and whatnot?
Coledboudreau On the software Ben used it looks that way but in more professional software you can have the cutter follow the path on the left, centre or right. This is usually referred to as tool compensation
wow man you are amazing :) thanks for the video :)
Which software do you use for designing CAD parts? Is it Autocad Inventor as Ai?
Could you pls tell me what software did this guy used on the computer to write the name?
Thank you sir. God bless!
Hi Ben
I found your TH-cam site a few days ago, and watched the CNC Router Tutorial. I have never used a CNC machine before, but I am going to build a small one (18" Sq. +/-).
I began watching the Mach3 tutorials. Very complicated. Does the program you use in this video take the place of Mach3? Also can a photo or other object be transferred from a computer to this program to be cut on the CNC?
Thanks, Tom
First, mach3 system is widely used. you can use carved program in your computer, its suitable to 2d and 3d.
finally, my whatsapp is +8615508689532 , if you meet trouble in your cnc machine, i will be pleasure to help you.
good luck
If diodes are used with the DC motors it would keep the voltage from going backwards to the board, when motor is moved quickly by hand.
+BlackLocustMusic Unless the motors operate in AC.
+BlackLocustMusic They are stepper motors. They are not really "AC", but they aren't exactly "DC" either. If you start putting diodes in to prevent them from sending back emf into the control board, they aren't going to run.
Hello Ben, I'm trying to find out how G-code is converted to the corresponding digital signals. I guess this is proprietary but the basic convention musts be generic. Can anybody help please.
Hello, sir, very interesting videos. Thanks
I would like to programmer pic,but in C language . What hardware and software i need? Thanks
Can you please tell me how to build cnc machine for metal engraving
"Hole-Hearted" by Extreme, not Firehouse!
huy Ben, your illustration is very good, but being a newbie I have a question i.e
What is difference between GRBL & G-CODE ?
Ben did an excellent job introducing CNC to folks who are new to the hobby. It's a blast to get into and doesn't have to be crazy expensive. Machines can be built for under $500 that are pretty capable. Or, a very good entry machine (3040) can be found on eBay or Amazon for around $600. There is all kinds of free and open source software available as well. There are even plug ins for Inkscape that let you generate the gcode right within the program: www.keerbot.com/generating-gcode-using-inkscape/
It can seem intimidating but it's really not after a short period of time.
I have a bunch of videos of my CNC build using drawer slides and fuel line hose. The machine has worked extremely well for all kinds of projects. I started with a rotary tool and then built a larger gantry to hold a regular sized router bit.

Hey ben can you please fix the lag or low fps on your video capturing? its hard to see moving animations
many thanks , but i was looking for the way to make my first project . please, can you learn me how to use software and how to export G code ?.
How about soundproofing the CNC machine itself by building a cage of sound absorbing material around it? Has anyone tried that?
hi in this video you use a program to write your name first then transfer it to Inkscape !! what is the name of the of the first program you used please:)
how did you record your screen???
I have little room in my shop. Ben do you think storing the system upside down bolted to a table that flips will require a lot of tweaking after.
That might be a good idea(make be think of this). I think I will just make a board that goes on top so when I need the space for something else just put board on top.
*****
That lift thing is too much work. It also could become a safety hazard. I'm also already storing things in that area.
Thank you Ben!!!!!!!
how does the program know how long the drillbit is
Thanks!
how can i leraning to use it before i buy it(CNC Router)
I wish this episode went more into general problems with CNC instead of Shapeoko specific stuff, like coordinate systems and how to choose your origin.
would very much dig a sit stand desk build by ben heck.
Hi Mr.Ben. nice to se the video and I want to buy that machine,
where can I buy it? thank you
Check out the Shapeoko 3 on the shapeoko website. I have just finish putting mine together but haven't run any programs. Has a bigger build space than most table mills.
hi dear, we also can offer this machine, wahtsapp +86 15508689532
Did Ben build this CNC or buy it? Are there plans anywhere?
Raising Awesome It's a Shapeoko (1, I believe).
www.shapeoko.com/shapeoko1.html
nerd bs
do you have any plans to share sir? thanks in advance :)
Do you recomend shopbot machines?
Can you build a larger CNC for ...larger projects?
Is it possible to cut aluminum with a router for a table top CNC machine like this?
Blast i don't know for the shapeoko, but there are table top milling machines that can cut metal (like the Proxxon MF70)
Really awesome ...
great overview, thanks. Gimme 10 years I'll catch up. :-)
Hello kamron which type knowledge you want for coin die engraving
Hi how to connect a cnc router machine to a mac computer?
Ben, we turn wooden and acrylic Pens on a lathe. We'd like to build some kind of CNC to engrave them.
Any suggestions? We want it simple and cheap, (if that's feasible)! And YES we subscribed, and thumbs up!
+Ted Mieske Hi,friend.I'm Carl from ACCTEK,a cnc router manufacture from China.We supply cnc router machines with best price and great performance.If yo have some questions about the cnc router machine,you can also feel free to ask me .My e-mail is export09@acctekcnc.com,hoping to hear from you soon.
Ben, You should build a portable touch screen computer, about 14 inch screen. would be an awesome thing to see built
