I put magnets on the bottom of my RasPi case, so when I 'go portable' with my SD4, I just slap the case to the side of the SD4, and print away.  Very handy.

Highly recommended, doesn't tie up a computer, and you can see the progress from anywhere with a web browser.

Has anyone gotten octoprint to work on a windows machine? I'm not sure if I installed correctly, the instructions for windows aren't great.  I've got an old netbook l'd love to put to use instead of going out and buying a pi.  I'm sure there's other ways to print wirelessly on windows, but I'd like the nice wrapper that octoprint has. Anyone have any tips?

Perhaps you can partition the old netbook and run octopi for linux. There are more instructions for that.

Seriously, that's a really nice use for a RasPi and looks like it's gotten a lot easier to set up since the last time I glanced over it.

I normally use an old (ancient) version of RH and slicer to crank out Filastruder hoppers. I need the Dell FX160 for an upcoming project, so I decided to try out Octoprint + a Raspberry Pi. I also added a PS3Eye camera to the mix, for print monitoring.

Steps performed:

1.) Grab the OctoPi image from here: http://octoprint.org/download/
2.) Install image to SD card with this: http://www.tweaking4all.com/hardware/ra … -pi-baker/ (if you use OSX. If not, get OSX.)
3.) Octoprint should autoload. You might need to boot into the Raspiban GUI in order to set up networking stuff. I also over clocked to TURBO SPEED.
4.) Access Octoprint from http://octopi.local.
5.) Set up for the Solidoodle:

Optional steps:
1.) Set up PS3Eye camera:

Modify the following lines of /home/pi/scripts/webcamDaemon

# init configuration
camera="usb"
camera_usb_options="-y"

2.) Set up flow rate and feedrate overrides - insert the code between appearance and cura into your ~/.octoprint/config.yaml file.

appearance: {}
controls:
- children:
  - command: M220 S%(speed)s
    input:
    - default: 100
      name: Speed (0-255)
      parameter: speed
    name: set
    type: parametric_command
  - command: M220 S100
    name: default
    type: command
  name: Toolhead Speed
  type: section
- children:
  - command: M221 S%(speed)s
    input:
    - default: 100
      name: Speed (0-255)
      parameter: speed
    name: set
    type: parametric_command
  - command: M221 S100
    name: default
    type: command
  name: Extrusion Override
  type: section
cura: {}

Bam:

You can tell its a 3D printer because of the way that it is!
