WEBVTT 00:00:00.080 --> 00:00:06.720 you can't have computerized numeric control without of course a computer and 00:00:04.400 --> 00:00:10.160 while the Linux pc embedded in the door might be weak the mill that it's 00:00:08.400 --> 00:00:15.440 attached to is capable of chewing through solid titanium 00:00:12.880 --> 00:00:18.960 but to help but to tell the whole story of this 00:00:16.960 --> 00:00:21.600 amazing machine i need to go back in time 00:00:20.080 --> 00:00:25.439 in time in time 00:00:23.359 --> 00:00:28.960 in time today's video is brought to you by glasswire are you worried someone 00:00:27.039 --> 00:00:33.920 else is using your wi-fi glasswire can alert you anytime a new device joins use 00:00:31.359 --> 00:00:37.880 offer code Linus to get 25 off glasswire at the link in the video description 00:00:44.559 --> 00:00:49.840 we've all been there you bring home your new furniture from ikea spread 00:00:48.399 --> 00:00:54.960 everything out on the living floor and go living floor kill me spread all the 00:00:53.360 --> 00:00:58.160 bits and pieces out on the living room floor and go what the heck was i 00:00:56.640 --> 00:01:03.760 thinking skimping on the assembly service well this video is that but on 00:01:01.039 --> 00:01:09.200 steroids due to covet restrictions tormach is not offering on-site setup of 00:01:07.119 --> 00:01:13.280 their cnc mills which means we're going to have to assemble it ourselves all 00:01:15.320 --> 00:01:19.360 2629 pounds of it so what do we do we 00:01:18.320 --> 00:01:22.400 just kind of go for it or what 00:01:21.439 --> 00:01:28.799 i mean hold on a second this is why we can't have nice things oh 00:01:26.400 --> 00:01:32.240 god he's been so excited to build this thing so much it's just been sitting 00:01:30.000 --> 00:01:37.280 here for weeks all right have fun see you later now i get to do the fun stuff 00:01:34.240 --> 00:01:39.200 so let's get a look at my new mill 00:01:37.280 --> 00:01:46.840 oh that's my timer i got to go get my copic shot and it'll take us this long 00:01:42.960 --> 00:01:46.840 we're back okay 00:01:54.159 --> 00:02:01.439 hello that's my new toy it's a tormach 1100 mx 00:01:58.640 --> 00:02:05.439 it spins up to 10 000 RPM it is an absolute unit so these are the chip 00:02:03.200 --> 00:02:08.800 trays these are what hold the chips as we're machining it catches the mess 00:02:06.880 --> 00:02:11.440 which our router doesn't do a great job of already 00:02:10.319 --> 00:02:13.680 and they are big 00:02:16.000 --> 00:02:19.640 that's a chunk of metal 00:02:24.400 --> 00:02:30.080 it's been two weeks since we started working on this machine we have to put 00:02:28.400 --> 00:02:33.519 all the sheet metal on the machine we have to hook up the pc we're gonna put 00:02:31.599 --> 00:02:37.360 on the tool changer and we're gonna get to play with some lovely machined parts 00:02:36.000 --> 00:02:40.400 and we'll come back once it's ready to actually start moving again 00:02:40.720 --> 00:02:47.840 everything about this looks really expensive yeah 00:02:45.120 --> 00:02:52.319 look at these yeah these are all balanced to go up to 10 000 RPM how much 00:02:50.000 --> 00:02:57.040 did i pay for these well they also sent a bunch of pretty carbide that is a 00:02:54.319 --> 00:03:01.519 sharp boy uh yeah so that's a three flute high helix aluminum finish wow 00:02:59.760 --> 00:03:08.000 yeah don't do that everything in here is now turning on and ready 00:03:04.959 --> 00:03:11.840 well no i mean you you told me these 00:03:08.000 --> 00:03:11.840 things don't stop for nothing so 00:03:12.159 --> 00:03:18.879 ta-da i'm not saying moving on why something's 00:03:16.480 --> 00:03:21.760 funky with why it's flashing green i bet you i didn't tighten the collar enough 00:03:20.080 --> 00:03:24.720 on the y-axis motor and i bet it's just spinning one of our new engineers is 00:03:23.440 --> 00:03:28.640 laughing at me kind of you know marveling at this knows i have no idea 00:03:26.879 --> 00:03:32.879 how to operate it here's something i know a thing or two about okay computer 00:03:30.720 --> 00:03:37.840 mice the ergonomics of this thing they could be a little better the finest 00:03:35.040 --> 00:03:49.139 silicone sheath over top of the most generic chinese mouse 00:03:50.000 --> 00:03:57.080 hey i'm covered in my chips this is this is fun but uh go flick a switch 00:04:12.159 --> 00:04:17.360 tool changes how do they work okay let's fill it with coolant 00:04:21.840 --> 00:04:26.960 oh oh that cooler pump's been running dry 00:04:25.199 --> 00:04:31.120 this whole time did you plug it into an accessory rather than into the coolant 00:04:28.720 --> 00:04:35.440 pump pump oh my god yeah okay well that might have destroyed 00:04:33.040 --> 00:04:40.440 the pump okay is it in the coolant one now 00:04:37.440 --> 00:04:40.440 okay 00:04:42.320 --> 00:04:44.639 okay 00:04:52.400 --> 00:04:58.000 now short of pulling off the CPU heatsink which appears to be glued on so 00:04:56.479 --> 00:05:02.560 i'm probably not going to do that we have no way of knowing exactly what this 00:05:00.560 --> 00:05:09.759 computer is other than that it's running four gigs of kimtego RAM it has a 64 gig 00:05:06.479 --> 00:05:13.440 pci express SSD another mini PCIe slot 00:05:09.759 --> 00:05:14.960 over here and a sim slot and then this 00:05:13.440 --> 00:05:19.120 is a funny one it's got about the banginess speakers that i've ever seen 00:05:17.440 --> 00:05:22.720 in an embedded machine but there's a good reason for that because when this 00:05:20.880 --> 00:05:26.479 thing is running it can actually get pretty loud so if it needs to make a 00:05:24.560 --> 00:05:30.160 noise that you actually need to hear from inside this sealed enclosure 00:05:28.240 --> 00:05:36.280 because that's pretty much the way to do it honestly though this little Linux box 00:05:33.039 --> 00:05:38.639 is not the most interesting part of the 00:05:36.280 --> 00:05:44.720 computerized control coming past our missed coolant reservoir we've got ah 00:05:41.039 --> 00:05:44.720 here it is and it goes 00:05:45.280 --> 00:05:50.800 so here is the 220 volt transformer so 00:05:48.720 --> 00:05:54.960 that's where power gets transformed into all the different voltages that we're 00:05:52.560 --> 00:05:59.280 going to need here is oh this thing is super cool this pretty much what it is 00:05:56.960 --> 00:06:02.880 is a gigantic ceramic resistor with a heat sink on it and what it does is 00:06:01.199 --> 00:06:06.639 whenever you want to stop the spindle spinning you actually need to take the 00:06:04.880 --> 00:06:10.720 power that the spindle would otherwise continue to generate and get rid of it 00:06:08.639 --> 00:06:14.000 somehow so it's just this gigantic resistor that just 00:06:12.240 --> 00:06:17.199 stops it right dead on the topic of spindle control of course we want to do 00:06:15.280 --> 00:06:21.120 more than just stop it and this puppy right here is our spindle vfd or 00:06:19.360 --> 00:06:25.600 variable frequency drive you could think of this kind of like a pwm fan header on 00:06:24.000 --> 00:06:29.840 your motherboard that can make it run at different speeds depending on how often 00:06:27.440 --> 00:06:35.039 it pulses power except on absolute freaking steroids so we can drive the 00:06:32.240 --> 00:06:38.160 main spindle at up to 10 000 RPM and all the way down to what 100 or something 00:06:36.800 --> 00:06:42.160 like that fancy the rest of this is cable 00:06:40.240 --> 00:06:46.800 management a variety of breakers and relays here's another power supply and 00:06:44.080 --> 00:06:50.560 that leads to this puppy right here so this you could think of as kind of like 00:06:48.240 --> 00:06:55.039 our secondary brains of the operation and what this basically does is it takes 00:06:52.720 --> 00:06:58.639 whatever signal comes out of our Linux computer at the front and turns it into 00:06:56.960 --> 00:07:04.639 something that all of our motors can understand so our x y z we'll all get a 00:07:01.840 --> 00:07:09.440 signal that they can interpret from this this is probably our best look at the 00:07:07.120 --> 00:07:14.000 clearpath servo motors that drive the x y and z axes so compared to stepper 00:07:12.000 --> 00:07:19.840 motors which are what we use on our cnc router they're not as torquey but they 00:07:17.039 --> 00:07:24.080 actually know exactly where they are rotationally so it can relay that 00:07:21.759 --> 00:07:27.280 information to the computer the computer can say okay i know exactly where this 00:07:25.680 --> 00:07:31.360 other one is and you can actually have the motors work together we could 00:07:29.199 --> 00:07:36.479 actually hard mount our tap and then we could have both our z-axis and our main 00:07:33.520 --> 00:07:41.120 spindle work together to just drive it in tap the hole take it back out and 00:07:38.880 --> 00:07:46.080 we're done i actually lied a little bit this one is not technically a servo 00:07:44.160 --> 00:07:50.639 motor it does have the same magnetic array and the same hall effect sensor 00:07:48.080 --> 00:07:55.520 that allows it to know exactly how many times it's spinning and where it is it's 00:07:52.720 --> 00:07:59.680 just that it sends that raw data over to our computer to process rather than 00:07:57.360 --> 00:08:04.560 having an onboard encoder that sends it out sorry however they do it tormach has 00:08:02.720 --> 00:08:08.160 another even more important reason for needing to know the exact position of 00:08:06.080 --> 00:08:12.960 the main spindle and that is for tool changes now on any normal cnc mill you 00:08:11.280 --> 00:08:16.960 would need to be able to change out your tools because you might have a different 00:08:14.560 --> 00:08:20.000 size bit or a different function bit that you need to pop into the main 00:08:18.319 --> 00:08:22.879 spindle so the way you would normally do that is you line up your little doggies 00:08:21.919 --> 00:08:28.639 uh oh there we go there it is look at that 00:08:26.639 --> 00:08:32.719 and then you press that again hey 00:08:29.680 --> 00:08:35.039 look at it go but this one is special 00:08:32.719 --> 00:08:40.159 this puppy has a carousel that can hold up to 12 different tool holders allowing 00:08:37.760 --> 00:08:44.399 you to do complex jobs with the tools automatically changing so what it'll do 00:08:42.240 --> 00:08:48.800 is it'll line it up exactly where it's needed the tool changer comes in grabs 00:08:46.399 --> 00:08:54.240 it spins around pops another one in the whole thing is pneumatically driven and 00:08:50.720 --> 00:08:55.519 the whole job just nice goes so cool of 00:08:54.240 --> 00:09:00.000 course none of this does anything without the computer to control it we've 00:08:57.680 --> 00:09:03.760 got a pretty sweet touchscreen interface for it but whether you're running 00:09:01.120 --> 00:09:08.000 touchscreen or a spongy mouse and keyboard you're going to be running a 00:09:05.279 --> 00:09:11.680 version of linuxcnc called pathpilot and one of the coolest things about 00:09:09.360 --> 00:09:16.320 pathpilot compared to mach 3 the control system that runs our router over there 00:09:13.920 --> 00:09:21.040 is that it actually runs at the speed of the processor with mach3 you send a 00:09:18.720 --> 00:09:24.240 command to the board that then processes and outputs step and direction signals 00:09:22.880 --> 00:09:28.640 to move the motor that means when you hit stop on the router it still has to 00:09:26.560 --> 00:09:32.959 process those extra commands before it even sees the stop now you can emergency 00:09:31.120 --> 00:09:37.760 stop it but doing that means you kill power to everything and you have to 00:09:35.040 --> 00:09:43.040 re-reference the machine which is a big boatload of suck on the tormach if you 00:09:40.080 --> 00:09:45.680 hit feed hole in a program it stops and we'll show you that but first just i 00:09:44.640 --> 00:09:54.080 want to kind of play around with this thing a little bit so if you want to set your your rip ems let's do five thousand 00:09:51.440 --> 00:09:57.839 meat huh we can stop it and then we actually put in just a little simple 00:09:56.080 --> 00:10:02.720 program here so it's just moving this back and forward on the x-axis and i'm 00:10:00.399 --> 00:10:02.720 gonna go 00:10:04.560 --> 00:10:11.200 let's stop and reset and show you guys something else that's really cool though aside from the tool and making sure that 00:10:09.600 --> 00:10:14.240 the path it's going to follow is right the main two things you need to concern 00:10:12.880 --> 00:10:18.640 yourself with when you're cutting different materials are the speed of the 00:10:16.560 --> 00:10:24.160 spindle and then the feed rate as the machine moves around on all the 00:10:20.720 --> 00:10:25.680 different axes while some piece of metal 00:10:24.160 --> 00:10:29.519 might be really consistent from one sample to the next a material like wood 00:10:27.760 --> 00:10:32.720 it could be all over the place and you could go yeah 2000 is usually good but 00:10:31.600 --> 00:10:37.279 why don't we try turning this up a little bit and see how it goes you can do all that without changing your 00:10:35.519 --> 00:10:44.360 program and you can do the same thing for your feed rate as well so if i stop 00:10:39.279 --> 00:10:44.360 this and i start my cycle again 00:10:48.640 --> 00:10:55.120 what of course you can have all the precision in the world up here but if 00:10:52.640 --> 00:10:58.640 your part is not held in place extremely securely you're just going to end up 00:10:56.560 --> 00:11:03.120 with a giant mess and that is where this comes in so this puppy 00:11:00.720 --> 00:11:06.880 right here is absolutely covered in these threaded holes that have these 00:11:04.720 --> 00:11:11.360 super handy little plastic inserts so what you can do is you can take say okay 00:11:09.440 --> 00:11:14.640 we want a mod vise here which is really cool because it can hold on to just a 00:11:13.040 --> 00:11:18.480 sliver of your material so you can work on one side then just like shave off the 00:11:16.480 --> 00:11:22.079 back we can put a regular vise in here we could put a fourth axis in here and 00:11:20.640 --> 00:11:26.399 then what you do is you tell the machine okay i've got this offset for when i'm 00:11:24.160 --> 00:11:30.880 going to mount it in that thing and without redoing your program re-zeroing 00:11:29.279 --> 00:11:34.079 or re-indicating the machine you're ready to free king go now one of the 00:11:33.040 --> 00:11:39.760 most useful things that you can do with this feature is you can add an additional 00:11:38.560 --> 00:11:44.399 axis neat right so unlike our cnc router 00:11:42.320 --> 00:11:50.720 which is perfect for making two and a half d parts the new mill here is four 00:11:47.760 --> 00:11:56.399 axis this is an a axis which is a rotational axis along the x-axis so you 00:11:54.320 --> 00:12:01.519 could take apart and you could actually roll it and work on the sides or on the 00:11:59.200 --> 00:12:06.560 back without taking it out and repositioning it super neat oh yeah this 00:12:04.399 --> 00:12:11.600 is a perfect example of the kind of part that what with maybe two or three resets 00:12:09.440 --> 00:12:14.959 you could make in a setup like this the bike pedal so colin's old job that's 00:12:13.760 --> 00:12:19.440 okay he likes his new job better debatable so as fact 00:12:17.120 --> 00:12:24.320 what does this go for it's like 35 40 grand 35 40 grand somewhere in there 00:12:21.839 --> 00:12:28.720 which raises the question why does a machine like this 00:12:25.920 --> 00:12:33.200 cost like it does most purchasers of something like this would be using it to 00:12:30.959 --> 00:12:36.639 make money and there's just a higher tolerance for cost when it comes to 00:12:34.880 --> 00:12:41.519 money making machines and as everyone knows money equals time so it comes down 00:12:39.360 --> 00:12:45.680 to what features it has that makes it faster and easier to use and that's 00:12:43.600 --> 00:12:50.160 where things like that fourth axis come in i mean being able to work on multiple 00:12:47.760 --> 00:12:54.480 sides of a part without going in and painstakingly moving things around and 00:12:52.399 --> 00:12:58.240 re-zeroing that's money right there of course for us that's not 00:12:56.240 --> 00:13:02.399 really the plan we're just gonna use it to like make cool stuff for our videos i 00:13:00.480 --> 00:13:04.839 guess we should do a demo right yeah let's make some chips okay well first 00:13:04.160 --> 00:13:09.440 thing safety should never be run 00:13:07.920 --> 00:13:13.440 without that closed and you guys are going to see why in just a moment here 00:13:11.120 --> 00:13:18.480 so this is cool it uses like an air blast to clean off the tool before it 00:13:16.480 --> 00:13:21.440 puts it back in the tool changing so which one should i use to hack up that 00:13:19.920 --> 00:13:24.800 aluminum block they're all good for doing that okay so what do i so now if 00:13:23.279 --> 00:13:28.079 you use the arrow keys on the keyboard you're going to jog up and down is page 00:13:26.320 --> 00:13:30.480 up pitch down that's really user friendly 00:13:31.680 --> 00:13:38.000 now you might think wow gee you're going to run out of coolant pretty fast there 00:13:35.519 --> 00:13:42.560 rick but it all collects in this little filtered reservoir on the bottom and 00:13:40.240 --> 00:13:46.480 then it recirculates it now normally we wouldn't have it in like flood mode like 00:13:44.880 --> 00:13:50.079 this for making videos but that's where the mister comes in i'm not gonna plunge 00:13:48.480 --> 00:13:54.880 it straight into the thing i don't trust you man come on colin give me a little 00:13:52.959 --> 00:13:58.720 bit i mean technically it's your machine oh there it goes boys see you later 00:13:57.839 --> 00:14:06.000 middle look at the metal shards at the back ladies and gentlemen 00:14:03.839 --> 00:14:10.720 you want to clean it up we got we got tools for that Linus 00:14:08.480 --> 00:14:14.000 ah sprayed me how many thou is this thing accurate to i mean i haven't 00:14:12.079 --> 00:14:17.680 dialed it yet i think the spec is two tenths of a thousand four tenths of a 00:14:15.360 --> 00:14:21.920 thousand it's like there's no burness there's just it's not even wet it's like 00:14:20.399 --> 00:14:26.880 because it's non-porous you made a clean surface so you can blow literally all the coolant off of it we switched the 00:14:24.800 --> 00:14:31.040 plugs in the back we are now in misting coolant mode here comes a misty boy do 00:14:29.199 --> 00:14:35.440 you want to position it just the tip and only for a second and only what never 00:14:33.040 --> 00:14:38.880 mind oh wow that's pretty wimpy isn't it it's called minimum quantity lubrication 00:14:37.120 --> 00:14:43.360 so it's just enough coolant to keep things moving if you need something to 00:14:40.720 --> 00:14:46.560 be say clean you can run clean fluids rather than a recirculating coolant you 00:14:45.120 --> 00:14:52.560 can have a different one in your mister versus what you have in your flood coolant it can get fancy oh my god like 00:14:50.240 --> 00:14:56.800 somehow it's both perfect and not sharp nothing quite like a brand new machine 00:14:54.560 --> 00:15:00.480 running brand new bits eh why that finish is so good is because when you 00:14:58.560 --> 00:15:03.839 plow a tool through a part it's going to naturally deflect and the router it's 00:15:02.160 --> 00:15:08.079 just so big it can't be rigid this little tool it's a lot denser and a lot 00:15:06.240 --> 00:15:11.199 heavier so it deflects less and you get a better finish yeah it's absolutely 00:15:09.519 --> 00:15:16.880 incredible almost incredible as my segways to our sponsor drop.com have 00:15:14.240 --> 00:15:20.800 launched a new unique keycap in collaboration with hammer that will be 00:15:18.480 --> 00:15:26.240 the envy of all your friends that's right they're bringing 2017 back

00:15:36.079 you went back in time and it comes in seven vibrant colors from transparent 00:15:34.079 --> 00:15:39.839 watermelon to spotted cheetah and everything in between i personally don't 00:15:37.839 --> 00:15:43.839 know what's in between a watermelon and a cheetah but i'm sure it's amazing it's 00:15:42.320 --> 00:15:47.680 the perfect time killer in between loading screens and game
