Having just arrived home from a quick trip to the hardware store, I was pleasantly surprised to see a large, unmarked, cardboard box sitting on my front steps. This isn't an uncommon event, since I am constantly checking out cool products and projects for the Maker Shed, however this box was a bit larger than normal.
Oh wow, it's the CupCake CNC kit from MakerBot Industries! I'd ordered it weeks earlier and had completely forgotten about it. (The truth is out: I have an atrocious memory, sad but true.)
And so the adventure begins! I'm going to document my "out of box experience" with a MakerBot. How many posts will the series be? I'm not sure since I've never built one. How often will I post about the build? Again, not sure, but I'll try to do at least one a week, maybe more, it all depends on how much free time I have between all my other maker-ly projects.
A little background: My CNC experiences
I've been tinkering with CNC for about 10 years, and consider myself an enthusiast, not an expert. I do own a few CNC mills, routers, and lathes. I have retrofitted old mills, and even build one from scratch. Pictured above is my mobile CNC machine, dubbed the "MobileC." I stuffed all the components into a mobile tool cart so I could bring it to hackerspaces, workshops, and events, all in the hopes of helping out fellow makers.
The mill is a Sherline 5400 that I retrofitted for CNC. Also, I added a few extra parts to make it even more useful. It has a longer reach, thanks to the headstock spacer block on the column, and a larger table that I simply mounted to the stock table. It's a sweet machine. I love my little Sherline!
All the electronics are housed in the cart too! There is a 19" LCD monitor, wireless keyboard and mouse, desktop computer, and CNC controller. It's a tight fit, but it works perfectly. There is even an extra full-size drawer for tooling and accessories.
I'm thinking of replacing the computer, keyboard, and mouse with an HP TouchSmart, but I have to save a few more pennies for that upgrade.
Does anyone want to know more about my MobileC? Let me know in the comments. After I build my CupCake CNC, maybe I should do a series of articles on CNC machining?
Disclosure:
I purchased the CupCake CNC kit with my own hard-earned cash. I waited several weeks for it to arrive, just like everyone else that placed an order. No favors, no freebies! Why did I buy one? Well, for two reasons.
- Reason #1 - I like what MakerBot Industries is doing for the open source community and open manufacturing, so I wanted to support them!
- Reason #2 - I am going to document the build for Make: Online, and if I like it, I'll let you know, and if I don't... well, I'll let you know that too! No biased reviews here.
Reason #3 - I am a CNC junkie, and I had to have it, even if my wife was questioning whether I really needed another machine in my studio! "Ha!" I said, "You can never have too many machines!"Oops, only two reasons, right?! :)
Questions & suggestions:
Ask questions! Do you want to see a better picture of a particular part, a different camera angle, a video perhaps? Maybe you have a suggestion for a cool mod or a hack? Let me know in the comments. I'll try to answer all of them as best as I can. Thanks!
Build history:
- Part 1: Introduction & background
- Part 2: Unboxing
- Part 3: Electronics
Awesome dude, I was hoping someone would do this.

Thanks! I think it's going to be a fun build.

I also ordered a CupCake - should be in next month. You'll be my vanguard ;) - looking forward to your progress.

You should remove the "taskforce" and CNC some custom lettering that says "MobileC"
Reply to this comment
That is absolutely on my list of to-do's. I didn't make it yet because I actually don't know if I like the name. MobileC? I like mCNC too. Any suggestions?

CNC2Go or "toogo" for short.

Obvious finger problem. *shrug*

Hmmm, I do like CNC2go. Could be neat with a superscript "2-go"

This is great. I've been contemplating a makerbot purchase for some time now, so this will help push me off the fence. I would like to see some pictures of the finished parts mostly. What types of parts can it build well? What types of parts does it struggle with (since there is no support material)?
Also, since you have some experience modding CNC's, I would like to hear your thoughts on what it would take to expand the build size of the Cupcake CNC. I've heard varying reports on what the limitations are, so it would be cool to hear an unbaised report.
Thanks and have fun!

I'll let you know about size limitations and/or expanding the build platform as soon as I get it finished. I haven't seen one in person yet, so I'm not sure. My guess is the biggest issue would be the rigidity and/or mass of the machine. You need "bulk weight" to help stabilize the machine, especially with bigger build sizes. Shaking leads to inaccuracy.
Ever move a knee-mill? I have, and they are HEAVY...and for a good reason!

BTW - is it possible to make a special feed for this series so I don't miss it in the deluge of other make blog posts? Thanks!

There are a few different solutions, I am trying to figure out what is best. I'll let you know in a bit.

Now you're going to make me really want one too! I shake my fist at you!!
Also, I'd love to see you go into some detail on your mobile CNC rig, too. You know, in all your copious free time :)
One additional request -- would you consider setting up your build area for a time-lapse of the build? I'll bet you're already planning that.
Reply to this comment
I will definitely get more info up about my CNC mill. It's a great little machine.
Timelapse? I don't have a good dedicated system to shoot time lapse, and I plan on building it in several locations over several weeks. (studio, shop, and even my desk for the later parts) It's a great idea, I'll look into it more.
I really should get a cheap camera and rig an Arduino to take the pics over an extended period of time. That would be an easy solution...or maybe my antique USB webcam might be the easiest solution?

How could you possibly *forget* that you'd ordered one of these? This is fantastic; I've been lusting after a CNC machine for months. Can't wait to read about your experiences!

I said I have a horrible memory! :)
Reply to this comment
Maybe a bit off topic, but does anyone know of a series of articles like this (or at least a complete easy to order/assemble kit) for a CNC milling machine?
Reply to this comment
I have a ton of CNC resources. I'll get a list together and post it up on a future installment, maybe one about my mobile CNC build? (and here too!)
Off the top of my head, Crank Organ seems fairly popular, but there are a ton of kits out there. Google "DIY CNC kit"!

Hello,
I'm looking to download the plans to construct my own wind generator using a treadmill motor.
Thanks, Wayne Holler

I've been keeping tabs on the RepRap for awhile now patiently waiting till it got far enough along in it's development to make the plunge. While reading a post on the RepRap on the Make blog I made the connection that Bre was involved with this thing called MakerBot and I've been drooling over the Cupcake ever since. I'm delighted to see this post and I look forward to the series. I've been "running the numbers" and making connections with people I know with laser cutters to see if I can scratch build one. At the very least I have some to the electronics bundles on my christmas list this year!

Me too! I really like RRII - aka "Mendel". I am hoping to make one using the CupCake machine for all the plastic parts. That will be my next series of posts! :)

Marc, you've hit on several topics that will keep me eagerly awaiting your updates. The Cupcake (and CNC milling) have interested me for some time but I hesitate to dive in because I have no experience with this sort of technology and as yet no way to experiment with it cheaply. The more posts and the more detail the better so please keep it coming!
Reply to this comment
That's great! I will try to be as detailed as possible (without going too crazy). Make sure you ask any questions that you might have along the way....I will try my best to answer them. As you can see above, I have a fairly good track record for responding to our readers! :)

I'd love to see an article about MobileC!
