CNC Build Club Double Feature – 1/23/2014

fsl3d

 

In addition to having Alden Hart talk about the TinyG and motion control in general, Andrew Boggeri of Full Spectrum Laser is going to show off their new sub $2000 SLA resin 3D printer. This is the printer that is currently crushing the goal on Kickstarter.

Stop by and check out the machine and see some of the prints.  Resin printers are a little messy to move around so we probably won’t see it print, but plenty of samples will be shown.  He will be able to demo the drawing speed, software and cloud interface.

The CNC Club is free and open to members and non members.  If you want to attend, please RSVP on Meetup.

CNC Build Club – TAZ 3 Unboxing

TAZ 3

 

Thursday (1/9/2014) night at 7pm we will have an unboxing party for Pumping Station One’s new 3D printer – the Lulzbot Taz 3! The Taz 3 prints larger and faster and in more materials than the other printers we have at the space. Come check out the mysterious BOX, see the printer set up, and maybe we’ll even get to Hello Squirreled.

Also, Ryan Pierce will be presenting “The Hard Knocks School of CNC Milling” covering how he made every mistake possible, and how you can avoid making them yourselves! This will include a lot of useful, practical tips, and a demo of the method he is using, showing the entire tool chain process, to route precisely aligned pockets for his and Elizabeth’s “CNC Steampunk Harp” project

CNC Build Club with Alden Hart: 1/23/2014

AldenHart

Alden Hart, the creator of TinyG and the grblShield will be in town later this month and will give a talk at the 1/23/2014 CNC Build Club @7:00pm.  The meeting is open to members and non-members.  If you want to attend, please RSVP via Meetup.

The grblShield is a basic stepper motor driver Arduino Uno Shield.  It is part of the standard parts list for the Shapeoko and there are thousands of these in the field. It can also act as a shield for the Arduino Due and run a special version of TinyG firmware.

The TinyG project is a multi-axis motion control system. It is designed for CNC applications and other applications that require highly precise motion control. TinyG is meant to be a complete embedded solution for small/medium motor control. Here are some of the main features of the v8 hardware.

  • Integrated motion control system with embedded microcontroller (Atmel ATxmega192)
  • 4 stepper motor drivers (TI DRV8818) integrated on a ~4 inch square board
  • Stepper drivers handle 2.5 amps per winding which will handle most motors up thru NEMA23 and some NEMA34 motors
  • Accepts Gcode from USB port and interprets it locally on the board
  • 6-axis control (XYZ + ABC rotary axes) maps to any 4 motors
  • Constant jerk acceleration planning (3rd order S curves) for smooth and fast motion transitions
  • Very smooth step pulse generation using phase-optimized fractional-step DDA running at 50 Khz with very low jitter
  • Networkable via SPI to support off-board devices and for networking multiple boards into multi-axis systems
  • Microstepping up to 1/8 (optimized DDA makes this smoother than many 1/16 implementations)

3D Printing Cage Match: 7pm Dec 12 at Beauty Bar

3DPCM LogoWe’re throwing a 3D Printing Cage Match Party at 7PM at Chicago’s Beauty Bar.

See factory teams, local businesses, and hobbyists compete to print a medieval weapon as fast as possible, and then fire marshmallows at their slower competitors!

Our own DJ Adam Dzak will be spinning, Jim Burke will provide commentary, and PS:One′s Lulzbot AO-101 and Makerbot Replicator will both be competing as well.

Want to attend? RSVP (free) here.

Want to compete? Register (free) here.

More information at the 3D Printer Cage Match Homepage.

Please note that this event will serve as the CNC Build Club meeting on the same evening.

Writing the Night Away with Writer Zen Garden and NaNoWriMo!

20131113 Pic 1November is National Novel Writing Month, or NaNoWriMo.  The objective is to write 50,000 words or more during the month.

One of the ways to do that is to attend a Write-In, an event where participants support each other, engage in word wars, and commiserate on the vicissitudes of the writing life – and otherwise abuse their vocabulary.

Tonight’s Write-In in the lounge was no exception.  We came, we wrote, and we played Go to unwind.  Writers worked on short story compilations, manga, speeches, and novels.  If you’ve always wondered what it’s like to write a novel, then by all means join us!  The next PS:One Write-Ins are Wednesday 11/20 and Wednesday 11/27 from 7:00 to 9:00 P.M. in the Lounge.

The Writer Zen Garden hosts a number of events at PS:One, including our popular Prompt Circle, Artist Way Clusters, and Plotting Workshops.  Check us out on Meetup or stop by an event.

Write on!

CNC Build Club – 4 Axis Milling

4th-axis_large

 

(picture from CNCCookbook blog)

This week we are going to play with the rotary axis on the little CNC mill.  We are going to assemble it and calibrate it.  We will use a demo of DeskProto to run a job on it.  We will of course start with the CNC Ninja Squirrel, then try some other projects.  It you have something cool to try, bring a file in STL format and a round piece of material to mill it out of.

Join us Thursday Nov, 14th at 7:00pm.

CNC Build Club: Shapeoko 2 Demo

Shapeoko

 

At the next CNC Build Club, on Thursday 10/24/2013 at 7:00pm, we are going to have a demo of the, soon to be released, Shapeoko 2 CNC router.  The ShapeOko was designed by local inventor, and PS:One friend, Edward Ford.  The original version was extremely popular.  The new version adds many new features.

  • Larger work area.
  • Easier to expand
  • Open front and rear for feeding stock through
  • Dual motor Y axis is now standard
  • More ridged
  • Belts lay flat and are easier to install

Shapeoko

 

It will go on sale at Inventables very soon.  Inventables will also be giving away one milling bit starter kit at the meeting.  This a a kit of 5 solid carbide 1/8″ diameter bits.  It includes 2 spiral upcut bits, 2 straight flute bits and 1 ball end mill.  You must be registered on Meetup for this meeting and present to  be eligible for the bit kit.  The meeting is open to members and non-members.

NERP: Implementing MIL-STD-1553 with 3 Beagles

Tonight Trefor Delve will present a distributed simulation development making use of three Beagle Bone Blacks as part of the network. The simulation is used as a proof of concept for a general purpose, configurable simulation platform making using of public domain software.

Mil1553_timingMIL Standard 1553 bus timing [wikipedia]

The presentation will introduce the principles of the MIL Standard 1553 data bus, show a simulation with simulated hardware and demonstrate the same software running on distributed Beagle computers making use of the Beagle’s ADC, PWM and SPI interfaces.

The presentation will also demonstrate the use of the QT widget set to allow remote virtual hardware to interact with the Beagle simulation.

The presentation will demonstrate the setup of the ADC, PWM and SPI interfaces using the system capabilities.

NERP is not exclusively raspberry pi, the small computer interest group at Pumping Station:One in Chicago.

CNC Build Club – CNC Controller Roundup

TinyG

 

This week we are going to talk about as many DIY CNC controller options as we can find.  All CNC  projects from 3D printers to mills require a controller.  This open discussion might help you choose your next controller.  Here is the list we are going to start with.

CNC Build Club – New Printer Demo

isis3d

 

A this week’s CNC Build Club  Thursday, 8/29/2013 @ 7:00pm, we are going to have a 3D printer demo from a new Chicago hardware startup called Isis3D.  They are going to demo their new Isis One 3D printer.   The printer has a large 300mm x 300mm build area and is producing some awesome prints.

isis3d_2

After the demo we will go back to our regular activities of discussing, building and using CNC equipment.  Next week we will gathering a huge collection of CNC controller boards including some cool new things like the BeagleBone Black running LinuxCNC and the Simple Cortex runnnig Smoothie.
