Must-watch video if you are interested into DIY, desktop manufacturing machines, hacking, making and generally awesome stuff!

Nadya Peek speaks about the process and basics of making machines that make, technology, digital fabrication economics, MIT modern high-end CNC machines and their limitations, how g-code is very stupid  and how biologists buy expensive machines that are easy and cheap to DIY ...
She also talks and shows many interesting machines that you can make yourself like liquid transfer and auto pipetting machines...



From video description:

Making a new control system for a machine is often a slow and tedious task. Maybe you already have a 3 axis stage, and you already know how to move it around. But what if you want to add a camera and use it for position feedback? You'd have to redesign the whole hardware layer.

I'll talk about some ways I've built modularity into control systems for machines so that you can quickly iterate on different kinds of machine systems without getting stuck in hardware land forever. This includes connecting synchronized nodes across a network and importing legacy nodes for things like, say, an old pressure box you found in the trash and has rs232 in.

Down with gcode! Long live machine control.

I found one of her presentations which loosely follows the theme of the talk in PDF format:

She also spoke about some high end CNC machines being monitored by gyroscope, sensors and GPS so they can not be moved without authorization to prevent them begin exported to blacklisted countries. Here you can see the perfect example of that crazy security policy: http://boingboing.net/2014/01/06/high-end-cnc-machines-cant-b.html


The talk was part of 30th Chaos Communication Congress (30c3) by the Chaos Computer Club (CCC) at Congress Centrum Hamburg (CCH)

GCode Simulator is software package of several programs / apps that run on PC or Android device enabeling you to simulate G-Code 3d printing on your PC and on Android and giving you full control of compatible 3d printer in paid (1,99 €) version.
This is very useful since there is plenty of very affordable low cost Androide devices such as tablets that can provide you with powerful touch screen 3d printer controller.

GCode Simulator also supports wireless printing over Bluetooth. GCode Simulator & Printer can connect to Bluetooth enabled 3D printers. Any RepRap 3d printer based on RAMPS can easily be extended to support Bluetooth by connecting a JY-MCU Bluetooth serial  module.

New Slic3r is out with many new features! Huraaaaaayyy!

From the news post:

Major new features:

• built-in automatic STL repair
• OpenGL 3D preview of the repaired file (thanks to iXce for the initial work); also supports multi-material files
• ability to override individual config options for each object in the same print job
• new support material rewritten from scratch
• new Ooze Prevention feature for multiple extruders (park extruders outside skirt and drop temperature by a specified delta)
• options to avoid starting loops on convex vertices and/or overhangs
• volume calculation
• ability to customize how materials are mapped to extruders
• new First Layer Acceleration option
• new option to use firmware-controlled retraction (G10/G11)
• new option to use a distinct extruder for support material interface

Improvements:

• Slic3r is now much faster because many mature parts of code were rewritten in C++ for faster processing and less memory usage (Slic3r is now 40% C++)
• most of memory is now truly shared between threads, reducing the total footprint
• improved infill patterns and bridge detection
• the automated test suite was largely enriched
• don't combine retract and travel anymore when using G0 (Mach3 compatibility)
• better Makerbot (Makerware/Sailfish) compatibility
• Windows binaries are now built with Expat for faster AMF parsing
• Minor improvements:
• new [layer_num] placeholder in layer-change G-code
• custom G-code can be supplied via command line too
• some options were renamed or rearranged for clarity
• new --info command line option to get information about the file
• add .ngc to supported G-code suffixes
• the wizard now saves initial profiles automatically
• automatically copy Simple Mode settings into a 'Simple Mode' preset in Expert Mode

Changes:

• layer height ranges are scaled automatically when object is scaled in plater
• avoid G92 E0 for sailfish output
• the "Infill every n layers" option was renamed to "Combine infill every n layers" to clarify its purpose

Bugfixes:

• several threading issues were fixed
• some situations causing incomplete infill were fixed
• fixed regression causing wrong direction for inwards move in holes, thus little blobs
• fix crash on Windows when username had non-ASCII characters
• some spiral vase prints had little gaps in the loops
• Z-offset was not applied to spiral vase prints
• lift was not working correctly with multiple extruders and multiple skirt layers
• fix speed math for wipe, which was causing too fast retraction
• other minor fixes
