3D print job notifications in Slack with Octoprint

June 3, 2016 by Chris Richards

I recently purchased a Taz 6 3D printer from Lulzbot, great printer BTW, and one of the things I wanted was a notification when a print job completed. There is no way to connect the Taz 6 directly to a network, but a quick search led me to Octoprint, and more specifically OctoPi. Octoprint gives full remote control and monitoring of your 3D printer with a ‘snappy web interface’. I had a spare Raspberry Pi, so opted for the OctoPi SD card image. Installation was a breeze, just follow the instructions to install OctoPi to an SD card and configure the WiFi. Insert the SD card into the Pi, connect the Taz 6 via USB to the Pi and boot. Once the Pi has booted you can access OctoPrint at http://octopi.local (or the IP address if your computer doesn’t support Bonjour).

Getting Mono running on an Amazon Linux AMI

September 4, 2013 by Chris Richards

This morning I spent some time getting mono running on an Amazon AWS EC2 instance. The instance is running a standard Amaxon Linux AMI, and the mono packages aren’t available in the default repos. After a bit of searching I found a post on the Amazon Web Services Forum that pointed me in the right direction, and is pretty simple once you know how.
