The subscribe on the Thinkpad was a really nice touch
As a certified nerd, I think (heh) the ThinkPad itself is a nice touch. Best laptops ever, even after years of Lenovo fuckery.
That crap was subtle as frig. Almost missed it.
I have to say....it got me *thinking*
Just got myself a older gen thinkpad T430, love it and T.O.T. Happy days.
it almost seems like there's one SUBSCRIBE reminder in every video, be it super subtle or patently obvious
it's a great Easter egg to look for. love Tony's attention to detail
a CNC pizza cutter is sounding like a great idea lol, right eBay here we go
I hope this is real. I'm much more fragile than I let on.
I’m hungry now .i can’t wait to enjoy a 1/24 size slice of pizza
Looking forward to your extreme pizza cutter colin :D
yes please!
@@red01Mustang why 1/24 of a pizza when you can have 1/36 of a pizza
I was a CNC programmer and R&D machinist for many years. When I started in the 70's it was NC (the first C hadn't been born yet) and we typed programs on a converted teletype terminal and then threaded the paper tape into a reader computer that was the size of a refrigerator.
This is the best, most complete instruction video on the interweb machine. Maybe these should be shown in schools. Nice job.
i searched exactly this on youtube and google many times but i could not understand them and suddenly i get recommend this video ♥️love u man
WOW! This is really the coolest introduction to CNC Matter I've ever seen! This video should be shown to young people in school if you want to get them excited about a career as a machine tool technician. Here, the basics of CNC control are explained in a funny and above all pictorial way. Verdict: Pedagogically valuable!
Magnificent video ToT! I went thru this process recently on my mill conversion and you made it very clear and accessible. Great job...
This Young Boy: "Dad, can i play with the etch-a-sketch now? Please?"
This Old Tony:"WAIT YOUR TURN!"
Best CNC video ever man ! Your explain is very good.
Not a TOT Notification.
Some 4 hours later it shows up in recommendations. Though it finally gave me some good ones, well one, but one I should have been notified about.
Great video! Very thorough.
BTW you can buy replacement keys (used) for Lenovo/IBM laptops on ebay for next to nothing. They're made to fit multiple models and sellers usually list the compatible models.
MOAR! And put some EL lights on it like Applied Science showed you!
TOT, ok so you thought you would really up the ante? Looks like the next step for AvE is to 'build his own Haas CNC machine' with parts from the scrap bin 😂🤣😂🤣. Yet another gem from the TOT studio. Thanks for sharin young man. Kindest regards. Joe.
Thnx for this clear explanation.
mean while, back at the ranch, the cattle were getting restless.
OMG I just figured out "C+C dance factory" is "CNC Dance factory". I'd been saying C plus C. It makes perfect sense because all of the music is synthesized on computers. Mind=blown.
Sorry for the way off topic post. I had to tell somebody.
Sorry for bothering, I'm just scrolling through comments 🙃
information at its best
Can you alter the G code or the tool path to remove the rope that's tangled in your sketches?
It is a limitation of the Etch-a-Sketch. There's no retract for the stylus. So all rapid moves are going to draw. That's why Etch-a-Sketches suck. I suppose someone could write a CAM generator that tried to minimize rapids? Or put the rapids over cut lines as much as possible. But that'd be horse crap.
Edge and sKetchy CNC, keep up threatning your pc oh and the Great work
You do a really good job at describing stuff... Well at least I think you do... Plus your style of telling the story is awesome!
Now you need to see if you can program so your airplane and horse doesn't get tangled in a rope. Maybe something to do with tool path? I don't know I just fix them and not program them.
3D Printer slicer software has options to minimize move paths and afaik it uses standard gcode. Just make 3D model and slice it in a single layer.
Cutter Slade Yeah I was thinking 3D printer slicers might put out better gcode. Much easier to get small “line widths” and sharp corners.
I was thinking about this as well. It should be possible to make it follow the same line backwards so it wouldn't travel point-to-point
Morten backlash might be an issue when backtracking...
@@kilrahvp I'm sad to say I've never tried an etch-a-sketch. Also it should be possible to compensate for backlash if the backlash is consistent
"tangled in rope" , I was thinking Salvador Dali.
Very cool TOT.
Man, i love this videos!
Hey Tony, what do you think about controllers like the Masso?
Clearing the Etch-a-Sketch.
The memories this project dredges up, explaining to my professor that yes we had burned up all the stepper motors in the lab over the weekend and that the minimum order quantity of etch-a-sketches was 25. (Same weekend) I though i really had put the nightmares behind me.
I did want to show a possible solution for clearing the etch-a-sketch, from the vertical, moving it through an ark of 190 deg forward (screen facing you) from the bottom edge clear it nicely. It is useful to know that the balance point is about 1/3 of the way up from the bottom of the etch-a-sketch. See video.

Tony, thanks for another fabulous video! I'm one of those 'mechanical' nerds, who think anything electronic is 'over their head', but you did a great job of explaining the logic of this setup, and I believe I could build a similar setup if I put my mind to it! Keep 'em coming!
I have absolutely no doubt you could. but only after... part 2! ;)
Nope... I blame our Governments. CNC IS 40 YEARS OLD !! Electricity is ancient !

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.
Wow!!
Andrew Myers nice reply.

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. Thank you for commenting.... we are all in the shadows sometimes.
I decided a long time ago that other people's opinion of me is none of my business. 😎
Linus Torvald would like to speak to you about your current lifestyle choices.
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).
@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.
@@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).
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.
Excellent introduction to the topic. Thank you for posting. I enjoyed it!
Hey man, i love your videos. I just want to let you know keep it up. You've inspired me to start my cnc drill press vice with your table saw video.
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 RUclips 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.
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
Dammit. You made me feel like this is something I can do. -=shakes fist at old Tony=-
Toooooneyyyy!
-=sigh=-
Whelp, I'm off to ebay... grumble grumble
Don't do it the way Tony does it. He spends money like a drunken sailor.
I know I am late to the party, really late but this is one of the most useful introductions to cnc I have found.. I like and enjoy your method of presenting information. Is there a specific video where you go into controlling the speed of the router? I’ll keep digging through your videos… great job… as always
why didn't youtube notify of this video, now I don't have time to put out roses on my bed or put on Labi Siffre let alone take my pants off.....thanks youtube you've just ruined my TOT experience :(
I don't use notifications, because I subscribe to a bunch of channels and I don't want my phone beeping at me all day. Usually I just go to the subscriptions tab and see the new videos, but today this video was not in that list. Way to blow it RUclips! The only reason I saw this video was published is because it was on the main recommended videos page, I wonder how many videos on less popular subscribed channels I have missed seeing. Does this mean they shadow banned TOT?
This is the second video from one of my favourite channels that RUclips decided to hide today: first Techmoan, now This Old Tony. This is not in my subscription feed, even though I'm subscribed, neither is it in my notifications, even though I have them set to "all". I will watch every TOT video that comes as soon as I see it, what possible reason does RUclips have to hide them?
Davyd: You do that too??
same.. I've randomly found the video and it wasn't even shown in my subscriptions. It happened more times :/
Looks like youtube started making the subscription feed more like facebook news feed.
same here, didn't, and still isn't showing in my subscriptions box
Thank you for this! Very nice breakdown of what's involved in putting one of these together. Definitely on my to build list now. Any suggestions on a good mill to convert? Seems like it's the dilemma of the mini lathe, or DC vs AC/DC tig where to do steel, it's going to cost a lot more (except inverse in the Tig example).
Save the trouble. Get you a Fadal TRM. It's going to serve you well. 3 axis CNC without a tool changer or flood coolant. (Use a mister) you can also run it with handles like a manual mill.
Wow, what a channel! And the only one I know where the comments complement the video in such a meaningful way.
Use the third motor to drive a fan...gotta keep cool when you're making videos this hot!
Actually this could be an interesting (useless) test. How big of a fan can a stepper motor run? Also thanks for the ❤
Love it, exactly what i needed to see. I've ordered the nema 7 kit for my 15t overhead crane already.
I think I've only ever commented on one video before, but this is by far the most informative video I've watched on YT and I'm even making notes with the intention of giving this a shot. Have always loved your videos, but since I had a stroke a couple of years ago, I've wanted to finally get a little more hands on with many of the "hobby ideas" I've picked up along the way since I started watching YT way back when. Now, this will be my first shot at this. Thanks, Tony!
I just convinced my wife that we need a mill.
How do i tell her that we also need a cnc router..
sigh..
Allesvoorkappers nl just tell here they are really cheap;)
I tried to talk my wife into getting me a lathe for xmas. How'd you do it?
20 buck a each pay check don’t let the wifo now next thing you know you can be like ave
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.
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 😁
stepper? hardly knower
If you want to make something that'll shake the etch-a-sketch just bolt a Nokia 3310 to it and give it a call :P
Or put in an offsettable weight on one of the motors and run it at resonance for the structure.

TOT, My Saturday is complete! :-)
[edit] AND Amazon runs out of etch-a-sketches!
you are an amazing youtuber, not only the content, but in using youtube and an audience, we have all heard the usual "leave a like subscribe etc etc" that even if its a channel that the audience likes, the audience simply doesnt, and if its a new channel, me personally, i dont do it on purpose because its kinda strange to ask for that, you however manage to make that suttle, interresting and funny!
For example 6:12, replacing the laptops logo, which everyone is used to seeing at that place, me being curious after seeing the mousepad and knowing it, uh, lets see if he had to remove that logo because of product placement or something, and its just saying subscribe.
seriously, altho thats just one example, that mindset spreads through every video on this channel, its amazing. its real, its not trying too hard, its just goofing around. its quite human. i love all about this
Machines playing with toys? Awesome! This is like that time Ken caught Barbie with Earl, a CNC machinist. I learned so much that summer.
Trey Cook,it would have been more believable if you said Ken caught Barbie with Keith instead of Earl! Although I think the Keith’s aren’t into CNC yet...
"Naturally occuring" motor...
Yup, that one made my day!!!
This is the most awesome-est build idea in the history of ever! I never quite felt the need to build any useful CNC hardware, but this calls to me in an unnatural way that I like.
I always thought that an Etch-a-Sketch needed a "space bar" (Z-axis, for "no line reposition").
I wonder if you could throw a small solenoid on the joint that holds the point (inside the 'sketch) to do that. On/off. Pen up / pen down. Hmmm. Now I want to open one up to see if that's possible.
The simplest version of this would be a little mechanism to push the stylus assembly down while you reposition it. I mean, it sounds simple on paper anyway
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 :)
Why do you need a CNC when you can just use special hammers to cut your work perfect?
Ah a childhood project :-)
one printer one Atari ST, the driver-ICs out of the printer and hot glue, a lot of hot glue, a lot!
The hard part was the converter to convert pixel-graphics into vector graphics into direction-controls with shortest lines to draw the image.
I've worked on that for months on my Atari ST and GFA-Basic.
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.
I wonder if there is a way in an Etch-a-Sketch to mod it so that you could physically lift the stylus from the screen to create disconnected lines. That could maybe be hooked up to a lever for manual operation, and hooked up to the Z-axis or a simple solenoid on a switch output. I know the single-line thing is half the fun/challenge when playing with an EAS, but modding is fun too for some of us nerds. I've never tried to do that, but I did take one apart as a kid and remember making a big mess.
I have been cutting parts out with my plasma cutter by hand for a long time…it’s time to expand! Thanks for the video and encouragement…a kick in the butt would have been more effective…let’s say….but here we are.
5:58 Nice ThinkPa- wait
Nice catch!
"CNC pizza cutter"
*Stares off into the distance imagining the possibilities*
How about wiring third motor to invert it and a fourth one with an off center mass added to it so it would vibrate like hell
Just one extra stepper should be enough -- invert and shake at a resonant frequency while rotating forward and backwards around horizontal a few times to get even distribution.
Shaped like a rabbit, with rotating beads inside...
Hi Tony, I would suggest skipping one or two slots between primary and secondary in the terminal block to increase the isolation. Just a tip, interesting video as always!
good tip!
The stuff where he connects motors to drivers and drivers to BOB (Breakout Board) is easy - he skips the difficult task - the connection to the PC entirely. The fact that parallel port may not be supported in 64 bit win 7 or windows above it, the software version compatibility etc. This is why he DID NOT use the original supplied BOB - it would not work.
Guess I'm masochist using Arduino xD I always looked at it as a lazy option compared to building custom pcb.
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
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.
I'm as confused as Michael Jackson at the Playboy mansion.
Christmas comes early this year! :) Thanks, Tony! Don't know where you'll be headed with this, but it might be really fun to implement and compare Mach4, LinuxCNC, and GRBL. Hey, look how easily I suggest work for someone other than me!
Kidding aside, I ended up using Mach3, then GRBL, and finally LinuxCNC on my mill conversion. The backlash compensation was the big missing from GRBL that caused me to bite the bullet with LinuxCNC. And I happened to have an old computer laying around that did the job.
Anyway, I love your work. It brightens my day any time I see you have a new video out. I hope your work on the full-length feature film of This Old Tony is coming along nicely.
As an official CNC expert, I can confidently say you did everything wrong, but I refuse to qualify what, for fear it will out me as not knowing anything about CNC.. I mean.. um.. hey, look over there!
I thought the title said Build your own civic
I'd watch that, to be honest. This is good too.
yes please :) :)
TONY! you heard the man!
Well, it's about the same amount of parts.
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')
Designing it: súper easy
Building it: easy
Doing the electronic stuff: mom senda help
(A mechanichal engineer)
Oh Tony, could have done this project with a much cheaper setup including $9 Arduino Uno (GRBL) for controller! Great into for beginners otherwise.
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............?
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.
@Mr TakisawaSee github.com/gnea/grbl/wiki/Compiling-Grbl
@@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.
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....
Yea Tony is my spirit animal.....
Ew, a furry :P
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...
And when you are done with making sketches you can make thermite with it to steal your own stash of methylamine
Any Braking Bad reference is a good one.
Could you please cover at some point how to use cheap DC servo motors and how to use encoder feedback on stepper motors. Also how to setup a controlled spindle and a PLC for running a tool changer.
Thanks!!!

Pizza, that’s what for dinner. Hold on one second while I order my wife to get Pizza, no no, I didn’t mean Order my Wife, she not Ukrainian, I will ask lovingly if she could get a Pizza. Ok back to the video.
im only eight minutes in....but i wanted to skip through or even go to a different video but ive decided not to becuase.. i enjoy the way youre presenting the information. good job. i will continue now
I've been building and running CNC machines for over 10 years now and still like to watch a video on DIY CNC every now and then. There's a lot of them out there but you made one that goes in the top 10. Nice work.
By the way, I've noticed you kept saying "I think it's a NEMA 23" or "34". 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.
NEMA's not metric?
@@Tricknologyinc NEMA stands for National Electrical Manufacturers Association (of North America). I measured the motors myself because I also thought the number was a metric reference, and sure enough it's 1.7, 2.3, 3.4 inches.
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.
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.
There is a way to turn off Microsteps, above the table you have SW1 1 to enable microsteps, so turning switch 1 off will make it go full 1,8° steps. :)

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.
A complete KIT OF 3 AXIS CNC IS SOMEWHERE ABOUT $ 300.00 .... WTF ... ARE YOU INCAPABLE ?
@@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.
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.
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?
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
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.
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.
Really? I thought ToT was in the interweb ....
He’s not in Europe
He's in New England. Or the Midwest. Or somewhere.
Kenny Phillips I’m in New England he’s def not from here accent wise
I'm not a welder. I don't own a CnC. I don't work with metal other than untangling necklaces for my wife and daughters, installing a new mailbox, and driving my car. That said, I amazed at how entertaining and incredibly educational your videos are, and wanted to thank you for all of the hard work you put in on them. My wife wants to say something as well, but I'm not sure this is the right place for it. Something about money, crazy ideas, and more important projects around the house. I just suggest nodding in agreement and keep doing what you are doing.
ha! thanks Marcus!
Hey Tony thanks for your excellent video. I always enjoy watching them, even though I'm not a metalworker. I watch you making stuff which I would never have thought it would be possible and see you using tools I never knew they existed. Your explanations are unique and full off humor.
It's a pity that there's people around on RUclips that seem not to understand what and why you're doing what you're doing and spend their time on producing negative contributions instead off using their time and supposed knowledge to something that good for this world. Well even from them we can learn. The lesson these people learn us is how to quickly turn our backs on the negativism they produce.
Please continue this series Tony, I am a diy woodworker and if I can find the time I will probably build along. My guess is there's more people around that would enjoy doing so. It would be very nice if we could find affordable hardware that maybe comes close to the standards you more or less advice in this video.
Thank you Tony, you have great info and videos. You have have given knowledge to me on subjects I work on at my day job that inspire me to expand my shop at home also. I'm an avid watcher and respect you sir. Thanks again
Me:*Looks at the corner of the room with the arduino/gerbil supplies* "Didn't have to call me out like that man."
Arduino UNO, GRBL Shield and pololu drivers + NEMA 17 motors would have done the trick, and the price point would have been a lot cheaper I think :)
You are 100% right, this is overkill.
Tony, that hurts, I'm one of those guys tinkering with Arduino. Oh well. Good crash, sorry bad word with CNC's, great short course on hardware for Steppers, I look forward to the software. Rock on!
Don't be scared of Linux. Besides you could run a virtual machine using Virtual Box. That makes the virtualizer, the OS, and the application software all free.
Im looking forward to more of this series, I have been wanting to build a routing/plasma table for a while now I have been looking at www.automationtechnologiesinc.com for parts are there others you recommend?
Other than PMDX and Warp9, if you need more hardware, try PoKeys? Though automationtech looks like they have some nice stuff!
360/1,8 so it needs 200 Kicks in the ass to get its ass kicked?
Ah yes, the classic IBM SubscribePad... What great machines they were.
One error I noticed: If you're using bagpipes to drive your CNC router, you don't need an air compressor; you need a psychiatrist. :)
The pros dont use Arduinos? My whole life Ive been lied to!
In all seriousness ive built a drawing bot that I controlled via the parallel port and LinuxCNC and it was a nightmare at times to map out the pins just because one parallel port didnt support 3 axis control and feedback (was using encoders) and then some pins didnt have enough current to push a signal through to the machine...so yeah those dedicated controller board definitely do wonders! Simplicity is the sane way to go haha
