Member Introductions

[TC]

There didn't seem to be a topic for member introductions so I thought
I would start one. I hope that people all members, existing and new,
will introduce themselves to make it easy for everyone to learn about
each other.

Here's my intro:

I've been watching from afar the development of RepRap and MakerBot's
CupCake for some time. I've recently gotten serious about building a
RepRap Mendel and have started participating the RepRap forums. I'm
located in the Merrimack Valley Region along the Northeast
Massachusetts and New Hampshire border. I'm an Electrical Engineer by
profession and an embedded firmware in my spare time.

I joined NE RepRap because I am interested in meeting and
collaborating with other RepRap folks in my area.

While it seems like this group is fairly quiet I suspect there are
plenty of lurkers checking in on occasion hoping to see activity.

SO... please post so that we know you are out there! If you post,
others will too.

[Tim]

Hi all,

My name is Tim; I live in the Boston area (Medford). I guess I'm not
such a 'new' member to NE Reprap, but have mainly been lurking so far.
I'm interested in several CNC rapid-prototyping applications,
including conventional CNC milling, 3D printing and automated
assembly. In particular I hope to start working on a CNC-based
automated pick-and-place machine for electronics assembly. I'm an
electronics + embedded software engineer for a day job, but have to
admit I'm a bit weak in some of the areas this hobby is leading me
toward! (e.g. high-level software dev, machine vision, and
CAD/Solidworks type stuff)

So far, I've built a quick-n-dirty conventional CNC mill and played a
bit with scripting (improved Inkscape DXF generator -
http://tim.cexx.org/?p=590 - and a music-playing MIDI to gcode
converter - http://tim.cexx.org/?p=633), but have not gotten started
with 3D printing yet. I hope to repurpose an old OZO router I have
access to as a general purpose router / repstrap / placer via
swappable toolheads.

My next CNC-related project is the conversion of the OZO router to
work with modern computers and machine controller software (EMC2,
http://linuxcnc.org). From reading the EMC2 documentation, it looks
like the hardware drive and trajectory planner can potentially be
hijacked for use by external software/scripts/machines by writing NML
messages directly to it (e.g. desired XYZ coords), so it may be usable
as part of a closed-loop realtime system (e.g. SMD pick and place with
machine vision for positioning feedback). Probably more of interest to
this group, an EMC2-based RepStrap converison is documented :
