Long time subscriber, first time commenter. Partially because I prefer to hide in the shadows like Gollum, and also because of the fear of public ridicule. That should tell you how strong the urge to comment is, especially given that what I’m about to say would be prime for such things. I’m a mechanical engineer who designs and builds cryogenic air separation plants for a living. I’m just painting the background here. But I also didn’t own a cell phone until 2 months ago, believe it or not. I believe that technology should have a purpose and until recently the phone served none to me. 20 some years ago in college, about the time the internet’s were invented, for my senior design class I built a CNC though it wasn’t called that at the time. I used the parallel port like you show but I wrote my own BASIC program for the output, which amounted to a bunch of nested loops with a print command to send a step. Fast forward to a few years ago and wanting a CNC router and coughing up $15k for it, and where I know that there isn’t anything to it and being extremely aggravated because of it. And despite knowing that also having to deal with the fact that I didn’t “speak the language” of the new technology to be able to learn from conventionally available resources. What I am trying to say is that for me, and I’m assuming others as well, this subject isn’t intuitive or easily learned. I very much appreciate both the time you are taking to explain it as well as your intelligence, demonstrated both through your sense of humor as well as your ability to simplify and clearly communicate. I need to watch this again a few times, make some drawings as that teaches me best, and look up some items, all electrical. But keep the videos coming. And the examples of different brands helps show what is consistent and probably important at this stage.

I have learned to accept that anyone who personally attacks someone is coming from a position of weakness, and I TRY to not let the comments hurt. I enjoy disagreeing (debating) with people about issues, but I don’t attack the PEOPLE (by assuming if they like x person then they have Y character flaw etc. I’ve also learned this... EVERYBODY has issues and insecurities. Some don’t admit it, some attack to cover it, some have the issue of not being able to see their own issues.

[@billqqq]

Great intro to CNC! In 79, I was a draftsman in a little fab shop that built optical flame shape cutting machines. We retrofitted the machine with a "Burny" - one of the first CNC controllers to the machine and created what was probably one of the first CNC sjape cutting machines. I programmed it using straight G code, and generated 1" paper tape on a teletype machine that was then brought out to the shop and loaded onto the burny unit. The oxy-acetylene torch was swapped out with a Hypertherm water cooled plasma. It was an exciting time and an experience I will never forget. It's amazing to see the advances made in CNC. Thanks so much for your excellent channel.

[@markschwarz2137]

Now that's what I call "step by step". (That honestly was pun-not-intended) Great idea to keep it 2-d at first, and the Etch-a-Sketch concept is brilliant. Suddenly a bunch of random stuff I've seen on this topic on KZbin is gelling, and after the next video in this series comes out I predict I will be able to build a seven-axis CNC from ten buckets of dirt and a barbecue.

[@finecutpost]

Thanks for the excellent video's. Have you ever done jigsaw metal cutting blades? Also hacksaw blades? I'm having to cut half inch aluminum for aproject and so far it's really slow by hand with the blades I have and cheap plunge saw blades are useless. Thx again

The amount of knowledge and comedy you pack in these videos is incredible. You remind me of this older gentleman I learned under when I was first cutting my teeth as a mechanic. I would listen to him for hours about anything he would talk about; some things relatable and applicable to a eager mechanic looking to find his niche in this world and some things that I just had no context for because of our 5 decade span of years lived. I can't relate to the prospect of starving, or packing up my newly wed and infant and traveling across the country just to find the job I had hoped for had been out of buisness for years. Jeffco, where ever you are, I appreciate the time you took to teach me about life.

[@andrewmcgiblets5784]

Linus Torvald would like to speak to you about your current lifestyle choices.

[@bdf2718]

Torvalds. There's more than one of him. Linux is fine for everything I do. Better than Windows. But then I don't do any CNC stuff, so I have no idea how LinuxCNC stacks up against Mach 4. As for CAD/CAM s/w for Linux, there's a lot of choice (which means there's probably no offering that will keep everyone happy).

[@bdf2718]

@Jim Alley Linus Torvalds (not Torvald) came up with something called Linux, which is an operating system. You can view it as an alternative to Windows except the price is a lot better - it's free. There is LinuxCNC on Linux as an alternative to Mach 4 on Windows. How reasonable an alternative I don't know. There are CAD/CAM programs for Linux, how good they are I don't know. There's a metric shit-ton of them, which is not a good sign, because a good one would crowd out the others. If you have an old computer sat around doing nothing because it's too underpowered to cope with Win 10 then it might be worth having a play with Linux, which isn't as hungry for resources. Because with Linux you tell it what you want to do (if you can figure out how, although standard stuff is easy, it's the non-standard stuff that has you tearing your hair out) instead of Microsoft telling you what they're going to force your computer to do (like do an update in the middle of running your CNC), or force a shitty user-interface upon you.

[@bdf2718]

@@RasmusJohanson I've hurd of this GNU of which you speak. They never did manage to come up with a kernel, did they? Well, they came up with something that was a pale imitation of Linux long after Linux had become solidly established. If we go down your route, it's actually xorg/GNU/Linux. Ummmm, Mate/xorg/GNU/Linux. Ummm, Firefox/Mate/xorg/GNU/Linux. The kernel is Linux, not Hurd. Much as I respect RMS, he cannot force me to call it anything other than Linux (nor can you).

[@erikjgreen]

Most people using LinuxCNC are using Fusion360 for CAM - it's an excellent package and free for start-up or hobby use. LinuxCNC is an industrial strength system... it has its quirks and it's more complex and less friendly than Mach, but it's been used to control all kinds of machines from little desktop routers to full size machining centers and lathes.

>It used to be true that Linux was the GNU software system plus the Linux kernel... nowadays it's mostly Linux+GNU dev tools+hundreds of other packages from other authors.

But I want to tell you that after having read well over a hundred hours of CNC Zone, Plasma spider, and mechmate forum, and hours of videos about CNC, Asking untold number of questions on mentioned forums, I did not learn as much as half hour video. AMAZING!!! "Imagine a GPS telling you to turn a mile late?" You really help one understand the why behind it. You are the best teacher I think I have ever watched on KZbin. Excellent content, no waste of time, detail oriented, witty and comical anechdotes/examples to clarify the points and engrave them on one's memory. It is not just displaying your knowledge, but helping us understand. Question: What was the best source you used for learning CNC? Would love to see a video on how you arrived at your knowledge of mechanical science, what the furnace of your education was to get you to this point. This is the highest praise I have ever offered in those ten years also. Well done sir! Glad I bumped into your chainsaw go cart video which led me to your channel.

It's pretty easy to figure out what is what--Nema 17 measure 1.7" across, 23s are 2.3" and 34s are 3.4"--although I suspect you already knew this.

I used duct tape to hold a couple of new epoxy bottle caps to knobs of my son's Etch-A-Sketch, then trimmed the nozzles until they were a press fit on the stepper shafts. I kept it set up for about a week, and used it to learn how to hand write my own G-Code. I've often thought of setting up another one. Thayer

[@WRW87]

you need to make a list of all the things you can do FOR HER with it. Applies to mills, 3D printers, routers, lathes... Anythings you want. More expensive = longer list.

[@ZenMinus]

Tell her you forgot to include the price of the controller for the cnc mill, and how the controller can create wonderful engravings on the jewelry you are going to make for her 😁

[@adamkeller5326]

I've been working on becoming a real machinist for years now and hope one day to become one. My most respected coworker introduced me to your videos and I must say I am thankful. Your video was extremely informative; and as I man with a million questions, you did a great job breaking down the operations of a cnc and have inspired me to replicate this project. Great video, thank you... look forward to more.

To drive a set of bag pipes you'll need? That's easy,,,,,,, you need a Scotsman.

I get so happy inside every time i see your trackball. All hail the trackball masterrace.

[@tomholmez12]

stepper? hardly knower

[@markspears1167]

Great video!!!! Enjoyed the humor. I’m a custom cabinet builder wanting to buy a cnc but I have a very limited amount of knowledge about them. This is the best video I have watched that explains how it all works and what’s needed to make it work. Great video! I appreciate the time and effort you put forth to make this. Bravo Sir!

[@garycaruso4883]

Oh Tony, could have done this project with a much cheaper setup including $9 Arduino Uno (GRBL) for controller! Great into for beginners otherwise.

[@stevenjkirby2020]

Yeah I was thinking exactly the same thing. Those nema 23s are waaaay overkill to move etch-a-sketch knobs. Could have been done with 17s and even they would be more powerful than they needed to be. An arduino/grbl based micro-controller board with integrated stepper drivers would be much simpler to wire too. Perhaps less relevant to Tony's audience though, as most will likely be wanting to convert a router/mill or other more heavy duty machine tools which will require more torque and therefore more current than integrated drivers could tolerate. I wonder if ultimately these components are destined for something larger than an etch-a-sketch............?

[@knickly]

I don't think so. I'm pretty sure TOT is converting this over to an etch-a-sketch channel, and there's nothing beefier that he'd want to turn. Unless he's got a bigger etch-a-sketch, that is.

[@olavl8827]

[@Gottenhimfella]

@@stevenjkirby2020 I don't think a motorised Etch-a-sketch is the point of the exercise. In fact I seem to recall Tony explaining that.

[@stevenjkirby2020]

If he explained it in this video then I must have missed it. I was probably distracted by some sort of clever video editing gag or a dad joke. If you read the whole of my comment you'll notice that I surmised ToT was likely intending on using these components for something larger. I mean, I'm sure he likes over-engineering things as much as the next guy but he's clearly not so daft that he'd put those big boy nema 23s on the etch-a-sketch permanently. He did work out time travel all on his own after all. Also, if you read the video description, there's a clue. Part 3 will be machine design. I suspect their final resting place will be on this mystery machine. Question is, what will it be? Surely not another router! Unlikely to be a lathe given the fact that he just added the servo driven lathe attachment to the router. The plot thickens....

[@ritchiep123]

This is an amazingly good explanation of CNC for people without an engineering degree. Keep it up.

[@kanekidaedric30]

Why do you need a CNC when you can just use special hammers to cut your work perfect?

[@larrylittrell1910]

Thanks Tony. That was is a simple and elegant way to explain the basics.

[@cocon16_PW]

Guess I'm masochist using Arduino xD I always looked at it as a lazy option compared to building custom pcb.

[@camrencarlyle5202]

I just refurbished a CNC from one of the breakout boards described to a specialized CNC controller with linuxcnc it was a plug and play operation

[@riippumatonlinja]

Think to do, cause of price. 600usd for board is pretty significant when you can do it with 5 euro board&drivers over that. Problem is of course big enought driver impulse, when arduino its couple milliamps and you need to multiple amps to drive those goodly. Perhaps step up converters or extra old pc power units for power up everything and another mid level power-signals with small relays to drive it, but pretty complicated, and then there is problems with cnc-language. You can perhaps use stls or something else free to use models to drive, but there may be some significant metal working stuff what mostly plastic and software-engineering people doesnt know and dont have prefixed options for diffirent metals to work with, even if there is software to understand diffirent tools and working speeds etc what i doubt. Still interesting problem build up small/mid size cnc lathe/router for most machining works stays one of ideas i want to build some day.

[@lewymartain8267]

Brilliant. About time someone explained something that everyone understands. You dont need a degree in Physics, Electro Engineering ect. Brilliant Tony!!!!!!!

[@riversvic]

After all those jabs I feel like I should go get my control panel off of mdf and take the tape labels off my steppers.

[@sbeavers99]

You literally knock me over with your subtleties. No really. By belly is way too old to be belly-laughing. Thank you.

[@terracar2003]

I thought the title said Build your own civic

[@tetherson]

I'd watch that, to be honest. This is good too.

[@momobadilak]

yes please :) :)

[@jackburton8947]

TONY! you heard the man!

[@lame007]

Well, it's about the same amount of parts.

[@vizionthing]

If you look at the history of the civic's it looks like its what the interns get to do as a first assignment, so ur not far off. (image search google with 'honda civic vintage')

[@josebaiturregui37]

I think no one on youtube has explained about the wire conections for a CNC being made and how and why do they go un a certain way.. also nobody explains it so f...cking simple as you.. standing ovation.. waiting for part 2...

[@askquestionstrythings]

Every time I want to do a Custom CNC thing... I have to remind myself of the costs of all those boards and motors. There is just no getting around the cost of hardware.

[@kennethkustren9381]

A complete KIT OF 3 AXIS CNC IS SOMEWHERE ABOUT $ 300.00 .... WTF ... ARE YOU INCAPABLE ?

[@askquestionstrythings]

@@kennethkustren9381 $300 is a lot of money at times. It's why I still don't have a 3D printer, A desktop CNC, A Laser cutter, a lathe, a mill, a tig welder, etc. Plus, I'm in the middle of a major career change so money is mostly allocated to that and not building things.

[@mildyproductive9726]

I think Kenneth is not including the cost of the mill, lol. My reason has nothing to do with cost. It's time and space. If I had all that stuff, I know exactly what I'd do with it. I'd make custom parts and jigs and tooling for those machines to make it easier and faster to make... better jigs and custom parts for those machines. And then I'd fix the occasional consumer good or neighbor's lawnmower, like 3 times in my life. There are only so many French Alex pasta machines to rebuild in my world.

[@borayurt66]

You can start with an Arduino UNO ( $3 for a good clone) + CNC Shield for UNO with 4 A4988 motor drivers ($10) + 3 Nema 17 motors ($25) + GRBL software for UNO (free) + GCode reader for PC (free)... This whole thing will cost you around $40 to do this Etch-a-sketch set-up. Also you can use this same setup and add a small spindle motor good enough for carving shapes on wood, plastics, aluminum etc for $20... Cheap enough?

[@sikedipuuhja7376]

for etch a sketch 28BYJ-48 tiny steppers will do the trick. they come around 2 bucks, and have integrated gear reduction - i guess otherwise they won’t be able to turn nothing. they’re soo small you can run them on 12V with a darlington array. their torque is amazing 0.034Nm though

[@borayurt66]

Wow! One of the best This Old Tony videos ever!... Keep it coming, can't wait for part 2,3,4,5,6,7,8....

[@alvydasurbonas8913]

grbl setup isn't that hard and i have made a stand alone cnc with arduino mega + grbl and reprap 3d printer shield with small display. Just haven't made the final version of mechanical part of my cnc. Version 2 right now but it is just to sloppy so it requires version 3 which is still in my head :). Reprap shield required some minor modification to run 2 parallel motors for x axis and accept 24volts power suplly, i use small step drivers (2amp) and nema 17 motors. And arduino can control larger motors just need more capable drivers. All i need to do is generate g code save it do sd card and put the sd card into reprap shield and start the job its nice to not have to worry about pc. But i think GRBL is limited to 3 axis only, at least it was at the time i played with it.

[@1pcfred]

If you want to build on the cheap make a fixed gantry moving table machine. You can't build a cheap moving gantry machine. As you've found out slop is unacceptable. My fixed gantry drawer slide machine can isolation route printed circuits in copper clad board. So it is not sloppy.

[@lundertied9966]

Brilliant! Concept of stepper motors explained in 20 minutes so that even I could get it! It's like retelling all seven Harry Potter novels in a tweet without any loss of content. I mean, I was a big fan of your channel before (serious content explained with lots of humour,), but this tops it so far! Please do keep it up, and please keep it as comprehensible as this first part! Many thanks and best regards from Berlin!

[@albertobu]

Tony I'm local from Vegas.. If somehow one day you decide to meet some subscribers which you shouldn't but if you do.. I'm in.

[@Xraller]

Alberto I think that was a joke about him being in Vegas in that one video. Pretty sure he is in Europe. Go back and watch the one about air gun and the brass counterweight he did. He mentioned he was in Europe.

[@manfredschmalbach9023]

Really? I thought ToT was in the interweb ....

[@weldingjunkie]

He’s not in Europe

[@UncleKennysPlace]

He's in New England. Or the Midwest. Or somewhere.

TOT it's hard to tell whether you're a better machinist or videographer . You do both with such excellent results. Thanks for quality entertainment !

[@momobadilak]

hey! -- I did one of those lame tape flag videos with a stepper motor - got like 6 views too ..soooo :) edit : it uses arduinos but no grbls :)

[@karanadon137]

Easily the best explanation I've ever heard on the topic! I thought you described the what's and why's very clearly. If I'm honest, it's also the only explanation I've checked out, but don't let that fact detract from the sincerity of my comment.
