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)

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.

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 – Gonzo Build with Moto!

Make With Moto

We have a very special event planned for the next CNC Build Club meeting on Thursday, July  18th.  We are going to do a Gonzo Build with the Make With Moto crew.  Make With Moto is a Velcro covered Sprinter van filled with making equipment that is touring the country.  In addition to the making equipment they have a bunch of unlocked and hacked Android smartphones.  They have been doing hack-a-thons around the country.

BL9LF5vCQAIlv6F

We thought it would be awesome to do something that combines our CNC hacking skills with their  phone hacking skills.  We would temporarily remove the “a-thon” and do a one night Gonzo build.

The plan is to do a digitally controlled camera slider.  The phone would replace the camera and control the motion.  We are still seeing what is feasible on the phone control options, but ideally you could control the phone from a second phone and view live video or snap shots from the slider phone.

It will probably look similar to this camera slider that was done in the past, but it will have a mount for a camera and have all the drivers on the slider.
