Thing-O-Matic Calibration II

I spent about an hour and 1/2 working on calibration on the Thing-O-Matic last night.  My prints are coming out very oozy on top.  The fan on the extruder also isn't running, so I need to open up the bot tonight and check out the connection.

Thing-O-Matic Calibration

Last night I did some calibration on the Thing-O-Matic, I was able to print faster than I've ever printed before, and was able to get some petty good detail.  I find that my printer leaves flat areas a bit rougher than I'd like, but then again it might be the plastic.  For some reason I find that the Tardis blue ABS that I've been using seems to come out a bit gooey from the extruder.  I think I'll re-run my gear test prints using a bit lower of a temperature and see what I get.

Thing-O-Matic Firmware

Last night I upgraded my Thing-O-Matic to use Jetty's Sailfish firmware, along with upgrading the extruder firmware.  The extruder was a bit harder to upgrade since it required getting a USB cable in at a very odd angle and detaching the connection to the main board, and the power connection to the PSU.  The main board upgrade to sailfish was easy as could be to do.  I'll be running calibration tonight so I'm hoping to get some good speed and quality.

Raspberry PI Day 2

While minor I installed python-dev, python-pip, tightvnc, node, and npm today at lunch.  I also pulled down socket.io and serialport using npm, so I'm all set for some python and node.js development on the pi.

8 Pin Arduino

For my first thing of the month I present this: http://db.tt/fa55SKqD  It's a Fritzing file  that provides a simple design for a 8 pin Arduino. It uses an Attiny and a few parts to allow a very cheap mini Arduino.  It gives you five digital I/O pins, two of which can be used for PWM, and three which can be used for Analog Input.  You will need a external programmer, to burn on the Arduino bootloader, and sketches to it, but at a build for under five dollars it's well worth it.  You will need the ATtiny library from the MIT Media Lab, and the Arduino IDE.
