DrawBot – The Delivery, Part III

Posted on by

So, I’ve figured it out.  Admittedly, it took until about 4:45pm today, but I figured it out.

Today was Friday the Thirteenth.  Duh.  That DEFINITELY explains my work day.

I was very happy to find the Adafruit Motor/Stepper/Servo Shield for Arduino kit – v1.0 had arrived from MakerBot.  When I opened1 the package I noticed that the kit really was a kit.  Which I already knew.  I knew this was a kit, but somehow I kinda forgot about it.

In a way, it’s irrelevant that I don’t have the other parts since I have to assemble this kit.  So, tonight I’ll assemble the motor shield and tomorrow, hopefully, I can assemble the rest of the DrawBot.

It’s not that I’m not materialistic or a complete stoic.  It’s just that my interests are so simple, narrow, and specific there just isn’t a whole lot I require out of life.  But for other happy and fortunate life complications1 I’d live in a studio apartment almost completely devoid of furniture except for a futon, small table, one (perhaps two) and book shelf.  Give me a library card and a laptop and I’ll show you a content man.  For example – one of my hobbies is origami.  Which boils down to basically a lot of paper. 2

While this means I’m easily content, it means those family and friends are frustrated at the thought of having to find me a gift. 3  So, for basically the first time ever I’ve put together a wish list with stuff I would love to get (in rough order):

  1. aka family [↩]
  2. A hobby which, hundreds of years ago could only be practiced by those precious few who had access to a luxury such as paper, can now be practiced by anyone in reach of a paper recycling bin. [↩]
  3. 500 sheets of A4 bright white multipurpose paper???  Score! [↩]
  4. Since I have none of the equipment or skills to perform SMT soldering [↩]
  5. Someone mentioned the modular thermistor set ups don’t detect temperatures properly – about 10 degrees too low?! Update:  Rick of MakerGear clarifies this was the result of a ring terminal mounted thermistor.  His modular thermistor kit pictured at the bottom of the this page shows that this kit allows you to make the entire thermistor attachment far more modular by covering it’s terminals in PTFE sleeves and then adding a connector.  This only makes me want this kit more.  Thanks Rick!

  6. Preferably one with George Plimpton’s face [↩]
  7. That’s a Simpson’s reference, FYI [↩]

How much for that doppleganger in the window?

Posted on by

Suppose you had a one MakerBot and just had to have a second.  How much would the rest of that MakerBot cost assuming you were willing to design and print every possible printable part? 1  Perhaps it would be in line with the $575 laserless MakerBot Cupcake CNC kit.  Then again, perhaps it would be the cost of the $750 MakerBot Cupcake CNC Basic kit less the $50.00 lasercut plastruder parts and $200.00 lasercut body parts, which would clock in at $500.00. 2

Are you really just $500.00 away from a second MakerBot?  That’s about half the cost of a Deluxe kit!  This brings to mind an even MORE interesting question.

What would you have done if MakerBot offered this deal:  Buy one Cupcake CNC Deluxe kit and get a Cupcake CNC Basic kit half off?

Well, if you already own a MakerBot, it’s like they gave you this deal anyhow!

  1. Including a printable Y stage. [↩]
  2. Admittedly, this assumes zero value to the lasercut external parts.  So, let’s pretend you have a box of the appropriate dimensions. [↩]

I purchased the MakerBot Deluxe Cupcake CNC kit – which came with plenty of tools and TONS of plastic.  The Deluxe kit came with things that you’ll need to operate your MakerBot such as the USB2TTL cable, power supply, and ethernet cables.

However, the wrenches and hex keys could be reused to build another ‘bot.  Parts printed up on a MakerBot could be used to print several very useful, and sometimes expensive, parts for another MakerBot.  The plastruder toolhead is $125.00 without the circuit board.  If you could print up the dinos, printstruder, idler wheel, and insulating retainer ring, you’re replacing all of the lasercut acrylic parts ($50.00 at MakerBot).  A persistent person could even replace all of the plastic spacers, wooden or plastic pulleys, the various wooden holders (Z rod caps, Z stage guides, X end rod caps), and probably even the  entire Y stage with printed parts. 1

Heck, if you had all of those parts you would basically just need a box in which to install them all.

Hmmm.  Anyone feel like designing a printable Y stage?

  1. In fairness, the Y stage would have to be printed up in several pieces due to size limitations. [↩]

Patience grasshopper, patience

Patience grasshopper, patience

Recent posts to the MakerBot Operators group show some people’s frustrations with this growing company. 1  Yes, they’re out of stock of electronics and other parts, but they’re also doing their best to crank out as many kits as possible.

Overall, I’d rather have them churning out robot kits than keeping spare parts in stock.  The plans for all of the electronics are open and free – you could have someone else fabricate them or build them yourself.  Still others have started up businesses selling lots of replacement parts and even upgrade kits.

We might be impatient for our kits, but they’re literally devoting their weekends and free time to getting these kits to us.  In fact, it’s their feverish dream to get a MakerBot kit into your hands.  You’re just not going to get this kind of devotion and service anywhere else.

I have one piece of advice if you’re waiting for your kit to arrive or replacement parts to be back in stock:  start designing stuff right now.  You already know what you want to build.  Just create a library of things you want to churn out.  Upload them to Thingiverse, get feedback modify, and improve them.  Heck, improve designs posted by others.

Your kit will be here before you know it and you’ll be happily (and woozily) sniffing ABS fumes too.  :)

Printed Dinos!

Posted on by

Don’t get me wrong – I like the acrylic dinos I have.  But what if you want to replace yours with a printed set?  Or what if you want to print up a full extruder kit for a friend?  Well, now you can!  I just uploaded some designs for a printed set of dinos.  Depending upon your batch you may have Big/Little dinos or Weird/Big dinos.  These should work in place of either, assuming that the placement of the bolt holes in the Z stage haven’t changed. 1

I’ve uploaded the sketchup files to make it easy to play with the designs.  As I was mocking these up I was tempted to turn them into bunnies instead of dinos.  Or to give the dinos some more features.  Since I was so torn about which route to take I decided to upload the bland models and let others embellish if they want.

So, print up printstruder and a few dinos for an authentic fully printed printruder.

Update:  Try out Zaggo’s printed dinos instead.  His is a much cleaner more elegant design.

Second Law, Schmecond Law

Posted on by

Unfortunately, in the haste to get the MakerBots out the door for the holidays the guys at MakerBot left out opto-endstop kits on some shipments.  These guys have been super responsive even before I bought a kit from them, so I’m not that concerned.  Frankly, it’s a little bit of a relief that I can skip the soldering stuff for now and move on to some of the pulley making steps.

In any case, as I understand it, these are not vital to the proper functioning of the MakerBot and that they’re really just a failsafe if the ‘bot forgets the second law of robotics.

I’ve been blathering about my MakerBot kit to anyone and everyone who will listen for weeks and months now.  All that is left to do is build it. 1  A friend asked me how long it would take me to build it.

Thinking aloud, I reasoned that if two skilled people could build one MakerBot in a weekend, I might have a shot at building one in about two to three weeks.2

I hope that’s not too optimistic.  :)

I guess that’s what Christmas miracles are for, eh? 3

  1. Oh, that’s all? [↩]
  2. Though a YouTube video suggest two people can build one in a single night. [↩]
  3. Actually, I would love to finish it in time for Christmas so I can print out some snowflakes for the tree, but I just don’t see it in the cards. [↩]
