CNC Build Club – Gonzo Build #2

One Axis Drawing Machine

This week the CNC Build Club is going to attempt Gonzo Build #2.  A gonzo build is where we try to knock out a complete CNC project in one night.  Gonzo build #1 was the Quantum Delta 3D printer.

This week we are going to build a one axis 2D drawing machine.  This uses two independently controlled carriages on the same axis to get 2D motion at the ends of the linkages.  The purpose is only to have a little fun and to cut our teeth on a simple inverse kinematics machine before moving onto a much more complex 6 axis machine.

ABS Smoothing – CNC Build Club

ABS Smoothing

Last night’s meeting was great.

  • A huge turn out of about 25-30 people
  • About 8 people certified on the laser by Colin
  • About 4 people certified on the vinyl cutter by me.  I started adding tips to the wiki page for the vinyl cutter because there was a little struggling to get good results.  I think it was due to not setting the orientation of the plot (worked for me)
  • I saw some certification on the LulzBot.  We need the linux computer for that fixed or replaced!
  • Ryan and Liz Certified on the CNC router and they cut a complete project on their own (cool little circle/star thing)
  • Acetone Smoothing….So it appears to make good prints look great and bad prints to worse.  You can’t polish a turd.
  • The Quantum Delta was slowly cranking out angry ducks and squirrels all night.

ABS Smoothing

ABS Smoothing

We did some experimenting with ABS Smoothing.  Donald J brought in most of the equipment which consisted of a heating pad, glass cookie jar and a little stand to put the parts on.   We put a small amount of acetone in the jar, then put 3D printed ABS parts on the stand.  When the acetone heats up it forms a cloud in the bottom of the jar, enveloping the ABS part.  Most of the acetone condenses back near the top of the jar.

It worked pretty well on finely layered parts.  It made some parts actually look little worse by highlighting flaws.   It took quite a while to heat up and could be optimized.  Donald is looking for volunteer ABS parts to practice with.

We have a temperature controller for it we can wire up.  It can only drive about 3amp @ 110V.  Does anyone have an SSR?  The mechanical relay probably won’t last long in this application.  The heater is probably 5-7 amps (guess)

This week we have a presentation by Jason Huggins (@hugs) on Bitbeam and the Tapster robot he built with it.

jason-huggins-with-tapster

When:

Thursday, May 9th @ 7:00pm, upstairs in the electronics area

Topic:

Jason will give an overview of Tapster, his open source, 3D printable, mobile app testing robot. In addition to explaining why creating a mobile testing robot is not the worst idea you’ve ever heard of, Jason will give an overview of Bitbeam, the open source building toy that he developed, which Tapster’s made out of. He’ll cover his making journey as he’s experimented with laser cutters, CNC mills, and 3D printers to make Bitbeam. For fun, the talk will also include live demos of Tapster playing Angry Birds.

About Jason:

Jason Huggins is CTO and co-founder of Sauce Labs, a software test infrastructure company, and is the original creator of Selenium, a popular open source web testing tool. In 2011, for an art project he was working on, Jason created Bitbeam – a 3D printable LEGO-Technic-compatible construction toy. Jason lives in Oak Park, Illinois.

Intro to the Microsoft Kinect – Recap

Us in 3D

We had a great presentation by Jarvis Schultz on the Microsoft Kinect last night as part of the CNC Build Club.  Jarvis works with the Kinect as part of his PhD research in robotics at Northwestern University.  We had an overflow crowd of close to 30 participants.

Us on Kinect

The presentation was an introduction on how to get started with hacking the Kinect.  He described what is known about the internals and the data you can get out of it.  He talked about the preferred open source software tools and libraries.

Kinect Depth Field

He gave several live demos.  The pictures you see above are shots of how the Kinect saw the crowd at PS:One.  The still shots don’t do justice to the coolness of watching it live.  His presentation is in PDF format here.

Microsoft Kinect Presentation – CNC Build Club

tracking_capture

Thursday, May 2 @ 7:00pm

Presentation

This week we have a presentation from Jarvis Schultz on using the Microsoft Kinect motion sensor input device and other related devices.  He is going to give an overview on how they work, what kind of data they can produce, what software is needed to interact with them, and what you can do with the data once you have it.  He will include some live demos of what the data looks like, and what you can do with it.

Jarvis is a fourth-year PhD student in Mechanical Engineering working on robotics at Northwestern University.  He is part of the Neuroscience and Robotics Laboratory, and he has been working with the Kinect since it was first available, and it has become an integral part of his PhD research.  Further information is on his research webpage in case you are interested http://nxr.northwestern.edu/people/jarvis-schultz.

Thanks to Steve Finkelman for arranging this.

CNC Router

Starting Pile Of CNC Parts

Following the presentation and discussion we are going to continue with the CNC Router project. We are going to add the limit switches for the X,Y and Z axes. Limit switches can protect your machine from over travel, but also provide an accurate and repeatable home position.

mach3-main-screen

We are also going to setup Mach3 as the machine controller. We will try to do this while hooked up to the projector, so everyone can participate in the process and learn how to do it. Mach3 is a professional level commercial controller and is a huge step up from the typical DIY solutions, like GRBL.

After a few projects with Mach3 we will probably also install EMC2 which is an open source, Linux based alternative to Mach3.

Last Night’s CNC Build Club

DSC00514

We had a great meeting last night.  We had over a dozen people working together to wire up a CNC control box.  At one point we had three soldering irons going at the same time.  Here is the pile of parts we started with.

Starting Pile Of CNC Parts

 

Here are some people wiring the box.  A really nice job was done using wire ferruls wherever we could.  How many hands can fit in that little box?

CNC Team Work

Here is the nearly completed box.

Box Almost Done

 

Thanks to Chris, Matt, Aeva, Patrick, Donald, Steve, Jason & Alex, Cat, John, Will, Gabe, Norm, Allen and Colin.  Next week we will be testing the motors, adding limit switches and configuring the software.

We will start with Mach3, then switch to EMC2 when we find a dedicated PC for that.  Chris and John I think mentioned they do time at Free Geek.  I am sure they could find a little PC.

Special thanks to Automation Technologies Inc for giving/lending all the parts.

CNC Build Club

Automation Technologies 3D Gantry

The CNC Build Club meets just about every Thursday at 7:00pm.  This is a weekly meeting of Chicago area people passionate about designing, building and learning how to use digital fabrication equipment.  Non members are welcome .  Each meeting starts with a round robin introduction followed by a little discussion and often a presentation or training session.  We also often have a group project going on.

This week we are going to start putting together a small CNC milling machine.  The machine was lent to us by Automation Technologies Inc.  Right now the machine is just the mechanical platform.  We need to add the motor controls, limits switches and setup some software.  The goal is to create an easy to use work center that we will do some projects on.  The plan is to sell the machine at a discount to someone in the group when we are finished. If you don’t know anything about CNC, don’t worry, you can still help.  The goal is to teach, learn and use.

Automated Manufacturing Night – Thursday, 3/21 at 7pm

Mike Vasquez will be giving a talk “The Printed Athlete – How 3D Printing is Changing the Face of Sports.”  It is free and open to the public.

Slide1

Over the past two decades 3D printing has radically shifted the way that many industries design new products.  The medical field uses the process for creating bespoke hearing aids and aerospace companies use it to design more efficient aircraft.  However, one of the sectors that is on the leading edge of this revolution is sports.  All the major sporting goods brands have started to adopt the technology.  From 3D printed high end parts for F1 race cars to multi-colored 3D printed footwear prototypes at Nike; the opportunities offered by the new manufacturing process has the chance to transform how athletes and customers interact with the games they love. This talk focuses on how 3D printing technology already has and will continue to revolutionize sports using examples from Mike’s time at Burton Snowboards and Loughborough University’s Sports Technology Institute.  Additionally topics such as the future of the technology and growing areas of innovation including mass customization and protective equipment will be discussed.
