Plastruder MK5 plans released!

The plans for the Plastruder MK6 look downright wicked
The plans for the Plastruder MK6 look downright wicked

MakerBot just released the photostream and wiki instructions for the Plastruder MK5. 1 This looks like a total overhaul of their original designs. 2

It is based on Charles Pax’s Paxtruder which has such a small form factor that it is possible to squeeze two extruder heads into one Makerbot.  The Paxtruder also uses a delrin plunger which is used to push the filament against the extruder pulley, rather than the previous idler wheel design.  I like the delrin plunger idea since it would be a lot easier to adjust tension and remove/insert filament.  The idler wheel held in by a large bolt and nut works… but is finicky and sometimes prone to fussiness.

Out are the big/small/weird and whimsical dinos in favor of lasercut acrylic “arches.”  There may be a benefit to the arches over the dinos, but I’m not sure what it would be.

The entire heater element and extruder head has been redesigned as well.  I don’t recall seeing any published designs which reference this new system.  We’ve all seen power resistors in use in RepRap/MakerBot projects – but they’ve usually been relegated to heated build platform designs.  Now a pair are being used as the full heating element in place of tempermental3 nichrome wire.  The problem with the old nichrome wire wrapped around the barrel system is that if you need to rebuild the heater, you’ve got to toss out the old nichrome since the insulation is going to get peeled off as soon as you pull it off the barrel.

The new MK5 system uses a PTFE sleeve to feed the filament down into the heater.  Interestingly, the PTFE sleeve is encased in a snug metal tube which should prevent any bulging problems.

My understanding of the instructions is that the MK5 is far less prone to failure than the previous MK4 model Plastruder.  I’ll grant the Plastruder is easily the most4  challenging component of the Makerbot to get working.

The instructions also hint at Generation 4 electronics.  Right now I’m rockin’ the Gen 3 which have served me quite well.  I wonder what the Gen 4 has in store?  One thing I have to really like about the electronics is that I know they’ll never really be obsolete. 5  If I wanted to upgrade to Gen 4, I can always print off a Mini-Mendel or Mendel, and swap in the new electronics.

However, if this new system is as resilient as the instructions describe, I’m on board.  I’m probably not going to have a good excuse to test out this new Plastruder design for a while since my Plastruder has been behaving itself since the last time I rebuilt my Plastruder and I just scored some spare MK4 parts6

  3. Pun intended!!! []
  4. Dang.  I’ve already used temperamental, finicky, and fussy…  Where’s my thesaurus?  Oh, that’s right – he’s out EATING Tony Buser’s Laser Dinosaur! []

  6. Thanks again guys! []

Poll results so far

The question is, “Should MakerBot hire MakerBlock to blog for them?”

So far the responses are as follows:

[pdrpiechart data=”Yes. Ill even donate a dinosaur. Or laser.=19|Only if they promise to make him blog LESS. =1|No freaking way. I hate that guy.=0″]

Vote now to skew the results!!! (The poll is to the right)

MakerBlock’s MakerBot setup

I’ve posted about other people’s MakerBot work space set ups,1 but not much about my own yet.

Right now there’s a bunch of junk2 in the way so no pictures of the setup for now.  My MakerBot – “Bender,” a laptop3 , and a large long cardboard box with a wooden dowel running the length with badly cut cardboard spools holding what was once a 5 pound coil of black ABS4 , a very nearly 5 pound coil of clear PLA5 , and a full pound of white ABS I’ve never used. 678

All of this resides in our living room on an enormous former-library card catalog.  For those of you youngsters out there, a library card catalog is the kind of thing you see in the background scenes of Warehouse 13.  Imagine a huge chest about four feet tall that has lots of small, deep, drawers.  It is what libraries used to use to store information about their collections – an analog database.  Frankly, I didn’t realize the one I bought was quite so large. 9  It’s literally big enough for about six identical MakerBot/laptop/plastic coil setups to the one I have. 10  The drawers beneath the area where my Makerbot resides are devoted to tools and spare parts.  Right now the surface is covered in a number of unfinished projects and some totally finished projects.

Library card catalogs are super handy and useful ways to incorporate storage and a raised level surface for working.  The only problem is that these things are absolutely enormous and way way heavier than they look.

  2. FYI, junk = stuff waiting to be made into other, more useful or more amusing stuff. []
  3. Named Bleys, if you must know. []
  4. I would guess I’ve used about a pound over the last 8 months.  5 pounds is a LOT of plastic.  Dear faithful ABS, oh how I love thee… []
  5. Polly!!!!!!!!! []
  6. Though, I have very specific and immediate plans for it. []
  7. More on this later if you remind me.  I have a tendency to get lost in nested footnotes and parenthetical references. []
  8. Seriously, just imagine what my PHP code looks like.  Yikes! []
  9. Or far away.  Or would become so expensive.  That’s a story unto itself. []
  10. I best get printing more MakerBots, no?  Hmm…  I might have to print more laptops too… []

Anticipation

I remember waiting for the letter which would tell me whether I got into grad school.  Once you send off your application, it’s out of your hands and just need to be patient.  I was waiting to find out if I would get the small envelope1 or the large envelope.2

I hadn’t thought about the small/large envelope anticipation for a while now.  I was only really reminded when I recently applied for a job.  I saw the posting about 8pm or so and stayed up way later than I’d like to admit writing up my application.

Of course, I had to follow up my application with a post about dinosaurs and lasers…  Both of which I happen to just have lying around here at MakerBlock headquarters. 3

Will I get the small or large envelope???

  1. Boo!!! []
  2. Yay!!! []
  3. aka my living room []

Thank you MakerBot!!!

Fluorescent red ABS and spare parts kit!
Fluorescent red ABS and spare parts kit!

Thanks to the generosity of my family I placed an order for a bunch of the MakerBot1 parts for which I’ve been pining away.  Ordered on August 10th, the box arrived on August 16th.  One of the things ordered was the MegaRainbow ABS plastic pack.

However, the box contained something else – fluorescent red ABS and a spare parts kit!

Thank you MakerBot Industries!!!  I have, indeed, had a happy birthday.  :) 2 I promise to only use these parts for good. 34

  1. And MakerGear! []
  2. I would have posted this a lot sooner, but it’s been a crazy busy week. []
  3. As for the black ABS that came with my Deluxe Kit I’m sorry to say that I cannot make similar promises…  that stuff just has a life of it’s own. []
  4. Is it an EVIL Rubik’s cube? []

MakerBot LCD screens

Perusing Capolight’s recent post about his LCD screen made me pine for an LCD display/simple SD print selection for my MakerBot.  I think Zaggo was working on something similar a while back.  Of course, there’s the RapMan with an integrated OLED screen.

I’m guessing I’m not the only one who would be interested in such an add-on for my MakerBot.  It’s not a terrible burden to have a computer constantly connected, but it would be nice to have the MakerBot slightly more independent of a computer.  Just bring plenty of plastic, electricity, and an SD card with your favorite things.

Unrealistic expectations

The guys at MakerBot just posted a job opening for a MakerBot blogger.  As if their list of qualifications wasn’t daunting enough, the tweet that follows…  Well, I’ll just let it speak for itself.

MakerBot Blogger Wanted: http://bit.ly/dur4vK (also: dinosaurs with lasers wanted)

You want a robot obsessed dinosaur with lasers? 1  What kind of a job posting is that?

  1. I don’t recall that as an option on career day. []

I’m sorry you had to find out like this

Dear lovely wife,

I never meant for this to happen.  It just sort of happened.  It all started so innocently – reading about the RepRap project, going to the MakerFaire, buying a MakerBot, starting this blog, extra plastic here and there…  and then MakerBot advertised for a blogger.

Tell the kids I love them, don’t forget to feed the dog, and there’s a post-it on the dresser for my boss.1

If you need to reach me, I’ll be camped out 87 3rd Ave, Brooklyn, NY 11217 until they let me in and hire me.

Love,

MakerBlock

  1. See?  I can be succinct. []
