It’s been a while since I last posted about my CupCake CNC build. OK, it’s been a really long time! Well I’m back on it, and I’m not stopping till it’s done. The good news is, we are on the home stretch. So let’s get back into the build by installing the X and Y stage. It’s easy!

Start by putting the X/Y assembly inside the CupCake CNC, and attaching the belt of the X stage assembly to the stepper motor pulley.

Next, add the remaining pulley to the opposite side of the printer’s base, and adjust the tension on the belt so it feels right. What’s right? You’ll know. It shouldn’t be tight, or too loose. I found that there is a fair amount of room for error, so don’t worry too much.

Now you can insert the M8 rods through the side of the CupCake CNC.

And into the flanged bearings of the stage assembly. Yes, that’s an end-stop there. Just pretend you never saw that! We’ll talk about adding them later.

Next, add the caps that hold the M8 rods in place. Note: I added a dab of hot glue to the ends of the rods. This eliminates “chattering”.

All done! Next up is part 10, building and installing the Z stage

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 hack? Let me know in the comments. I’ll try to answer them as best as I can. Thanks!

Build history:

    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

    IMG_9098.jpg

    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?! :)
