- เผยแพร่เมื่อ 19 พ.ค. 2017
- We welcome Bar Smith and Hannah Teagle to show us their Maslow CNC cutting machine, which comes in a $350 kit. This CNC uses an upright design to hold a 4x8 foot sheet of plywood, and is completely open source. We talk about the goals of the Maslow CNC project and what kind of big things it can make!

Why couldn't you make a standard template out of paper or cardboard that would set the table and all hardware into a standard location to help every 1 no exactly where to mount each axis point , sounds like a really innovative product though great Idea to keep price down
I m in the UK, and this project interests me. Are you shipping internationally?
How much tension is on the chains?
How are you making allowances for chain stretch and wear?
You said that calibration is only required once. But surely over time chain stretch and wear will cause issues, not least because some sections of the chain are likely to be subject to more tension, and more often, therefore likely to cause uneven chain stretch and wear throughout its length.

The only problem I have with Purchasing this machine is that they have no customer service number where you can talk to someone. The price they are selling now you should be able to have someone you can contact
that presenter is really good. he asks real questions. in all his videos he asks exactly the questions that should be asked.Clearly an engineer himself.
wish more people thought like them: "how far can this be developed" rather than "how much money can i make from this". well done guys, hats off to you. 😊
They are definitely making money off this. The kit doesnt even include the router, or shopvac. It is essentially $350 for the linkage, assembly, motors and micro-controllers. While its probably not a lot of money, this CNC machine isnt really practical for anyone besides hobbyists. Its not extremely simple for the average person, and its not precise and robust enough for professionals.
What about development of the electonics, development of the user inteface, development of firmware and support of the shipped products? These are all costs/development time you have to include into your final price. Also supporting an open source community is often a full time job and you have to afford your food somehow ;-).
since it is designed around an arduino mega the price point is both cheap and expensive at the same time. I've been working on parts acquisition for a desktop CNC when I have the spare funds and I think just on the electronics side so far I've spent $30, and that is even with finding the lowest price boards I can source.
I'm more of a "how much pizza can I eat today?' guy myself.
LInuxCNC runs this kind of nonsense out of the box. It was done over 10 years ago.
What a brilliant solution!
14:04 to see it in action
Thanks man
Love the spirit involved with open source projects like this :).
i can't believe i haven't seen this! subbed to the notification squad AND i'm an original kickstarter backer, but this video completely skipped my radar! should be arriving soon. cool to see Bar and Hannah get the recognition and appreciation they deserve for this, and running an incredible campaign in general. can't wait to CNC!
Have been wanting a large bed CNC for years. What an exciting project!! Can't wait until these go into production!!
That's so cool. It's kinda like a delta 3D printer, but the third "arm" is just gravity.
Also I thought that was Simone from the thumbnail.
exactly what i thought, a delta printer
Reminds me also of those camera on a wire systems that you see at sporting events that seem to float in the air, although drones may have supplanted them.
These type of cnc cutters were originally used as a writing machine. Usually a maker in place of the router.
Love it! This will make full size CNC routers available for almost every designer.
This is brilliant, I recently had a project in where my cutting space was 4x4 and needed a total length of 7'. I would have been able to cut it all at once with this CNC, very well done!
This CNC made me tingle all over my body. Would be perfect for building a boat. Either stitch and glue plywood, or converted with a plasma cutter to cut the sheet metal for a small steel boat or something. There's no end to the possibilities!
S&G was the first thing i thought of too.
Bar has mentioned in various venues that a canoe is on his build list... I imagine once he gets a moment to breathe, that will be the first thing he makes.

You could probably do it, but I don't think it is practical. The lasers that are powerful enough to be useful for cutting things are rather big, and require cooling. They are also expensive to replace... and some of them are expensive. (most of the laser tubes?)
If you made it big enough, you could dangle the whole laser assembly... but the cut would be very small...
You could create a mirror system, but I suspect that the stabilization of the mirrors so you don't burn something else down would be expensive.
There is a new router system coming out that uses your muscles to move the router, and a camera to track the work location and small motors to retract the Z axis if you get off course, and small motors to finely adjust your motion.
I'm interested in tying one of those with a super huge one of these.
or have a tool changing system on the router.
you could not use the normal 'fixed laser + mirror' approach, as the sled rotates as it moves around. you would have to mount the laser to the sled.
There are people making solid-state laser heads to go on 3d printers, that approach could work.
another issue would be the safety, you would need to enclose things to protect you from reflections.
How do you control the depth of the router cut? Do you need a special router with some sort of electronically controlled depth adjustment (I assume that exists???) or do you have to stop the cut after each pass and manually adjust the depth? I would assume that manual control would not work since you program in the tabs.
There is a small motor next to router with a threaded rod or a combination of carriage and track to adjust depth. That is my understannding of it from this video. You can see it at 15:32.
They make a Z axis kit you can add on to your router to make it a 3 axis machine.
But I was wondering that also, how does it work without the 3rd axis? Do they just run it slower (a router should go though 3/4" plywood easily) or like you said and manually adjust after each pass?
Edit: Did some reading on their website and they do just like you said and the program stops and lets you manually adjust the router depth after each pass that is about 1/8" deep.
I was wondering the same thing... so with the z axis kit it's $410 then unless you want to do it manually??
I guess you could just go through 90% then drill a hole and run a flush trim bit on the back side
From the install guide on their site the Z axis kit is basically a motor you attach to the manual depth control of the router. The threaded rod seen in the video is part of the original depth adjustment, doesn't come with the kit or anything. Still a really interesting idea though.
When running without a Z axis kit the software pauses between passes and directs you to change the depth.
Damn that looks awesome. I'm already trying to figure out where I'm going to put it.
Roof !!!
I am always impressed when I see people innovating and having the energy and drive to get off their asses. This is motivational. Thank you and good luck.
That is without doubt the coolest power tool I've ever seen. Well done for thinking outside the box - this solution would never have occurred to me - and I've improvised more than a few special purpose tools in my time!
Yes I’m gonna have to get my set up 🙃✌🏽good peeps hope they continue their success your humble way of awesome 👏
Absolutely brilliant..
This video reminds me the first time I saw a table saw and wanting to reinvent the wheel! Ran to buy a skill saw and mounted to a table ! Later on realized it was a waste of time and money ! Great concept , great motivation !
I guess I missed something here....How does the bit go up and down for the multiple passes and to leave the tabs?
I want to see how Adam might customize this! Maybe a frame that changes size and angle!
Jax Nean - I agree! And who know knows... it's possible a future version (Maslow 2.0?) could be upgraded to include 2 extra motors/2 more chains!? Regardless, it's a great intro unit for home hobbyists!
Probably just glue some star wars logo on it and call himself good.
It's nice to see some intelligent, well spoken and well meaning doing what they love.
Great work!
I've worked with a router before, but 20 minutes seems long for that sword, non? Would have been better if they showed a little piece (like half a minute) in real time so you'd have an idea of the speed.
I'm impressed. This would be PERFECT for people who want to do custom cutout decorations for holidays.
You got me really excited when you said $350, and designed to work with plywood. I love making wooden sailboats. I can see an immediate project application for this. I could make small tweaks, cut them, and try it out. That is amazing. I see this in my wood shop in the future. Strong work folks!
more like $700 by the time you buy a router and make the frame. $350 is a bit unrealilistic.
This is awesome, well done!
I would have liked Adam to go over it as he is more the workshop guy but was awesome none the less
I agree but it still in beta I think he will get a chance to make a review in the future.
Wow, so cool! Thanks for keeping it open source
Grant thanks for finding this!Bar and Hannah . . . wow!
This is pretty cool and I would totally rock one of these things in my garage! That said, wood in it's native form is a tree, not a 4x8 sheet ;)
Late response but he did say ply wood and not just native wood
I currently have a Grove of 4x8 plywood trees, I also have some 5'x5' Baltic Birch trees too.
Hahahahhaha fucking hell
that would make it really easy to make your own mame cabinet.
Awesome setup and I thank the makers who thought out loud for people like myself who can't afford a expensive CNC machine!!Thank You
how have i not seen this.. this is amazing, must have.. wow.
when doing a video like this in the future, it'd be awesome if you did an unboxing segment or a view of everything that comes in the box. it was a little awkward through the portion where the maker was explaining what was in the box
secsec1 also half the video was a view of their backs...
yeah, not the best produced tested video. loved the idea and the story behind it, but the video could have been executed better.
Keep in mind they're in beta still, so final production box doesn't exist yet.
Totally get it, just wanted to give some feed back.
here's a picture of what they ship i.imgur.com/3RSUv1Vm.jpg i.imgur.com/z0c60qTm.jpg imgur.com/rvh2vnV
*Wonderful CNC technology !*
Tech like this will make our world better, or at least we can sit in CNC chairs :-)
Wow, that is incredible, what an innovative idea made so accessible.
IMHO CoreXY has more advantage in precision and speed for not much more complexity (unless I'm missing something). Any opinions?
How about a folding frame, like a scissor mechanism? Then you could minimize it for storage or use differences sizes for different wide plywood.
Findecanor the problem with that is that it would throw the calibration out, so you'd have to calibrate every time you set it back up. depending on how often you use it though, might be a cool idea
Calibration is fucked if you use wood anyways. It's going to warp, shrink, and expand due to humidity and temperature. It might not be the biggest issue with a large CNC machine, but its why wood framed 3d printers are a joke.
Yeah 11 ply birch plywood doesn't move a whole lot.. If you get the shitty big box stuff then yeah it will move a bit, but the dudes cutting with a 1/4 inch bit too so it's not that involved
You could expand the system to have it self calibrate. One simple way i see to solve that is use strings attached from the router to the frame that are connected to a pulley system with encoder wheels. You move one of the top chain motor in one direction for a defined distance, and measure how far the router moved on the other two strings. With some math applied you can then transform the X-Y referenced gcode into your machine axis commands in the controller board firmware. Thats the beauty of open source, you are free to build upon someone elses work and try to expand and innovate ideas.
ac3ofspades878 Limited thinking. In the age of digital, you can compensate for any anomalies. My 3D printer has leveling feature that it goes through every time to make sure every print is level.
"Do I look at the camera? Or do I look at Norm"
To the guys @Maslow CNC, I gotta say, that is very ingenious, good luck guys in your excellent idea and project and I'll be certainly having a look at your website as that looks fun with loads of possibilities, and luckily for me, my brother is a design engineer, and I can see us having some fun with this.
could it be retrofitted to work with plasma as long as the frame was made of steel?
sorta similar to this one kid that has a hanging 3d printer using string and gears making the build size just about any size saw on thomas sanladerer channel one of those maker faire like videos recently
It would be great for making speakers
I was thinking the same;) use a 45deg router bit
Nice work Hannah and Bar! Can't wait to try this out later this year!
Wow ,so much negativity from your viewers,I personally think this is a wonderful tool to sell to people like myself that have no CNC experience and would otherwise not have a opportunity to try something new and innovating as this .keep up the good work best wishes T2G journeyman sheet metal worker
@@timmy2guns1 What are you talking about? The guy wants to get one??
Totally getting one when I got the room for it. Real creative design
If the software is called "Ground Control", is the router called.....um...."Major Tom"?
Lmao
Lmao
no. its called david bowie.
@@troyna77 Did he have screwed up eyes and screw down hairdo like some cat from Japan?
@@troyna77 Yes, but, which bowie? Space bowie? berlin Bowie? black star bowie?
If the guys at Make It Extreme get their hands on this, it will be powered by two angle grinders with a plasma torch attached lol
It'll be powered by 5Kw electric engine and would mill through an inch thick metal plate.
ooooh, gotta have one of those. Yah, a 50' mural idea has been on my mind for ages as well. A huge color printer.
Rumor has it they're still cutting this project today. Will be done any year now.
One day build for Adam, I need to see what Adam's brain can do with this
You inventors are AWESOME people! Loved your video!! Loved your ideas!!! It gives me hope that I may be able to actually buy a CNC machine someday. Thank you for doing this video. A vertical CNC machine - who woulda thought!!!
I was just wondering. (And it was not covered)
In this type of setup, how much mess does it create? I am talking about just the cuts from the CNC with the vacuum. Not the hand saw.
Thanks!
the best idea I have seen in many years. You guys are the best...
I'd like to see these kids become successful...
"Plywood in its native form" LOL.
I thought that was funny too.
That brings back memories of time on the plywood reservation. Seeing all those 4x8 ft sheets of plywood roaming free in their native form in their natural habitat still brings tears to my eyes.
@@Paul-sj5db What a truly beautiful experience that must have been. You're a lucky guy to have seen the thriving plywood population before the great migration and eventual extinction of the species!
isn't plywood in native form, really just wood chips?
Well, don't you all know???? .... PLYWOOD comes from the North American PLYWOOD TREE !!!!! ....and after SO LONG, they get around to the demo....THEN he stands there, holding the plywood sword in front of ....(drumroll)... the 4 X 8 sheet of PLYWOOD.... which PROVES the theory you CAN make things disappear ....in plain sight !!!!
Still, I loved the video...gives me some ideas....please, on the next vid, THINK. Love ya' all.....
This is absolutely fantastic. I would like to see this project mature a little bit but I am going to get one of these for sure.
This is freaking AMAZING!
Awesome idea. Cool design. But these two have something so odd about them 😂 they look at each other so weird! Hahaha
It's a really cool idea and I want one now. It's a bummer he stood in front, blocking it for most of the video though.
I also want one and let me know the cost if u r shipping to Ghana 0243074274 on whatsApp and ericeduyawgh@gmail.com
How awesome are you guys, a cnc for less than the router you put on it. One for the people so selfless. Props to you.
Amazing. I'm getting one. Me and my father-in-law are about to spend too much time on this...
He can program, too! What a great gig being open source.
1up on you guys!!
Clever. Why didn't I think of that? it ain't like I didn't have a chance, I've been a CNC Machinist/Toolmaker Machinist 26yrs. 🤔🤣😑 love it!
as working in the cabinet maker trade for 13 years and using cncs its cool idea but dangers as hell, one lil knot in the plywood and that router would jump off the board, looks like it would be better suited as a laser cutting system no highspeed parts, if u want to use this with a router there should be somethingto keep it firm to the board at all times and a couple bricks couldn't do anything, think more like wall panel saw style
T- Spat assuming that you made the disc large enough it would be possible to use the polycarbonate disc that the router is mounted on and the vacuum used for dust collection to create a basic vacuum hold down to decrease that risk, but I suspect that they rely heavily on the weight, using a high speed router, and then - as they specifically mentioned in the beginning of the video - utilizing a very slow feed rate to reduce risk of exactly what you mention.
I agree that this, or any CNC system is much better suited to the more precise methods of laser, plasma, water jet or even slurry or air jet depending on the materials being cut.
Of course cutting & material removal are not the only CNC applications this might be useful for, they mentioned one other - which was painting murals on the sides of buildings, but it would be equally good at producing billboards or other large scale advertising signage if equipped with a multicolor spray head
@@SFX95901 I would imagine the slow feed rate also reduces the torque twisting the entire cutting head changing the chain geometry.
This is pretty great. I will definitely look into this.
It's very cool idea!
The part that really intrigues me is the math that had to go into programming the movements given the changing angle of the chains.
aa the fact that they cut the sword in the middle of the sheet makes me so mad
Right!! I wonder if they did that for being safe since they said they are working on calibration hiccups, and didnt want it to go out the board in the demo. Lol
A Home Depot plug. No one ever says Lowe’s 🤔
You have a point
Seriuosly I love the way they think... Thank you..
Brilliant! Will read more about this and possible make a purchase.
(original creator of makercam here) Maslow looks really cool! How's the depth of cut controlled?
Why is your website based on Flash? It's 2017.
A Z-axis kit is available that mounts a motor/encoder on the router's depth adjustment. In the absence of the Z-axis kit, the software will pause and ask you to adjust the depth.
I wrote it in 2010. But if you want to port it to javascript the sources are online.
I kind of prefer the idea of that hand held cnc router that was on the show a while back. :/
The Shaper Origin is a nice machine, the one thing I don't like about it is you can't do anything else while you cut things. With this you can walk away and be productive otherwise.
jmalmsten it costs 6x as much as this.
Yeah costing 100x as much lol
jmalmsten I think they have that already?
How about the electronics, the controllers and other power supply? do they come with the kit?
I so want to see the 50 ft. "Mural Printer" version in action! How awesome would it be to have a revolving public art mural that automatically "updates" every few months!
nice web cam cover at 10:48
At least show footage of it in action...
I can't believe some of the comments. These are two young people with a passion for creating a new product and with a little luck, put a few bucks in their pocket. They are both adorable. I intend to Buy one. Support their dream.
Amazing, thank you!
Product idea is very interesting. Presentation needs a lot of work
Nathan Vancil I thought he did well but she was a little shy probably. Honestly the product speaks for itself. Even without a flashy pitch I instantly wanted it and that speaks volumes
The more polished and slick the presentation becomes, the more costly the product gets. I am left wondering if more polish would add anything more, and my answer is no.
Well then, it sounds like you should steer clear of this. Next stop: $20,000 flatbed CNC that takes 2+ weeks to set up, knock yourself out!
BTW, did you notice that this product is a DIY "kit of parts" (pretty generic stuff), so the assembly and it's "dodginess" falls on...yep, you guessed it, YOUR shoulders, not theirs.
So this is your magic moment to go create your own sub-$500 large format CNC, create and post a beautifully polished video of it, and lastly please, please, please ensure that the video and the build are NOT "dodgy" because that box of parts has a big "?" hanging over it.
SuperBardley not just sub $500 CNC that's not that hard they also have to go sub $500 with a 8'x4' work area
You're right of course, but I was trying to go easy....
I know that the hero of this video is a CNC, but am I the only one bothered with the way these two are so coy with each other 😂
Great idea, love it.
Your project is fantastic, congratulations. I found you by accident, h started to follow you, there is much to learn from you. Well done. Raffaele from Parma.
they seem very unsure about a lot of things.
Hunter Davids nah, its just the format. More like a live stream than an edited promo
I just think they're not used to this type of situation where they are being interviewed
Norm stop being so awkward
Leave Norman Alone
are they accounting for the rotation of the router as it translates? because that's a function of the CG of the router, which is inconsistent because of the bricks. if they can restrain the rotation then I suspect the accuracy will improve toward the edges of the work piece.
CG= Center of gravity, I assume...and no, that inconsistency isn't from the bricks, it's from uneven angular tension on the chains away from the center of the work area. One fix is in the software calibration, but another possibility is a more distant stability weight (i.e. hanging on a stiff arm straight down) to prevent the carriage from torquing.
You guys are legend. Made my mind go all over the place.
350 is pretty steep just for 2 encoded Motors (can get 2 stepper motors with planetary gearing for $50), 6 sets of bike chains ($50 Amazon), 4 bike sprockets ($40 Amazon), 100 ft of Bungee chord $30, I guess the other $130 is for the calculation equation (a^2+b^2=c^2) and or that circle of wood with bricks on it.
No frame,No router,No shop vac
To add z axis add a normal stepper Motor to a router base that has an adjustable depth of cut screw
Pretty steep? You just broke it down and see they aren't making that much money.... You're out of your mind. $350 is exceptionally adorable.
I8THEmagictoaster The math is far more complicated than what you posted because with this setup you are not guaranteed right angles and thus must use more complicated formulas from which the one you posted was derived.
wouldn't it be a lot quicker and cheaper to use a jigsaw?
Jeffrey Smith CNC is good for mass production or a bunch of the same/similar parts and it saves time for small things too
Absolutely. We’re great at over complicating things by finding solutions for problems we never had. (Bring on the hate, millennials)
a lot shittier, too.
That depends. A router bit is a spinning round bit while a jigsaw is a rigid blade. With that in mind, a router is great in making circles, detailed or fancy edges, dados, rabits, miters, insets, etc. While jigsaws are great in making non linear lines within reason.
That said, adding a mechanized xy system to the router would simply create an even more percise router that is able to stencil out patterns, detailed or simple, and cut them with expert percison. Since it is router based, that also means that it is not limited in curve radius like the jigsaw and can even carve out fonts.
But as I said, it depends since it's a question of time. If you want to cut out a simple shape, even something like the sword, it might take you less time to roughcut the sword with a jigsaw and sand it out rather than design, program and wait on the cnc.
CNC 2 axis routers were designed for large projects, super persise designing, an/or mass production.
also I'm wondering about the precision of the whole thing.
Does their positioning system takes the rigidity of the chain, the weight of the router, the friction of the base of the router, the catenary between the anchor points and the router, the wear on the bit, into account ?
pretty cool. I wonder if you could scale it up to cut parts for prefab buildings? Go to a site set this up along with a pallet of plywood and one of drywall and just go to town cranking out parts for the building. I wonder if you could line up a stack of two by fours and use the preprogrammed router to mark your cuts then just finish up and assemble the building
That is pretty cool. I might be able to adapt that fairly easily to connect my everlast plasma cutter to it.
Wow. 13 minutes of yacking and 30 seconds cutting. Neat, but I want that 13 minutes back.
As the official unofficial keeper of time I hear by give you back said 13 minutes. Go forth and make.
Hippies machining....who'da thunk? 🤔
Ed M 🤣
Aren't hippies with tools called geeks?
Nicely done. Thank you for sharing
Great to see young people coming up with new and great ideas
Fuck they beat me to it.... :( I've been working on this exact design for 5 years in my free time... wish I had more time to devote to my stuff....
Nathan get one and join the open source community.
Why would I buy one when I've made one of my own already.. I'm past the concept; mine works. Mine is just not releasable to the community yet; it's rough user interface and other stuff that I had been working on to make it commercial... I wanted to release mine as a full product that would cost $200 or less, mass production through my brothers company..
Join the community and see if their software can support your machine (or your software support their machine). The design and software is all opensource. If you have improvements to make it would be great to see them.
There are people participating in the community who missed the kickstarter and assembled their own components.
lol trolled..
Pretty sure I can make that sword with my jigsaw in less time
But can you do it 20 times perfectly without stopping?
pretty sure IF i hired you to cut 60 swords out of a sheet of plywood, your labor would cost more than the electricity it costs to run the maslow.
im curious how the program changes the bit depth for each pass
Absolutely beautiful. Way better than the 3D printed option I built that takes hundred of printing hours.
Router suspended on a rope? OSHA would be proud. Better keep those blades diamond sharp. One kick and at best you're buying a new router. At worst you're going to make your ER doctor laugh out loud after you explain what happened.
FallenBytes I routinely kill people who bump into my scanner.
Lol, that sounds more like a personal issue rather than a safety issue.
FallenBytes no one kicks my machines anymore?
what are you talking about? do you really believe someone can kick a 150 pound machine and cause the router to spontaneously jump out and hurt you? stop watching horror movies. your statement has no basis in reality. all that would happen is your work piece might have a very small nick in it.
I think he is saying that the router itself could kick out of the cut and swing around exposing the spinning bit. There is a lot of torque involved and those bricks may not be enough resistance to prevent the entire router assembly from flipping around.
20 minutes later? How much faster would a sheet of wood, a pencil and a hand held router be.
BAZE and much less accurate, not to mention that where CNC shines is complex shapes or repetition. cnc doesnt really make sense if you just want a wooden sword, but if you want 50? set it up once, load a sheet of plywood in every hour and then youre done
I have no idea about the subject really. My statement was more of a question with out a question mark if that makes sense. :)
20 minutes does seem slow by CNC standards for such a small outline too.
Uh.... do you feel like routing or cutting 30 sheets of wood for s kitchen? No... no you don’t.
Another important part that people didn't mention is that it's automated - Sure you could be faster by hand, but during those 20 minutes you can do something else entirely.
Awesome concept guys. Just wondering, would it be a good idea to add 2 more motors at the bottom that clone the diagonally opposite motor? Might improve accuracy
Totally gonna buy one
