• Octoprint:
  • Already done:
    • RaspberryPi-B, USB wifi adaptor, SD card have been gathered and at MakerFarm
      • apt-get, rasp-config and OctoPrint upgrades have been done.
      • changed default user/pw of R-Pi.
      • set timezone
      • set keyboard to PC104-US
      • Network setup with static IP at 10.1.10.221, on WiFi
        • Note, seems OctoPi has FUBAR'ed wlan0 auto setup.
    • Setup Port foward for below on ComCast Router.
      • 22180→80(HTTP)
      • 22144→443(HTTPS)
      • 22122→22(SSH)
      • Note
        • There is no DNS at the space, yet.
        • ComCast is DHCP, and there is no DynDNS setup. So you just need to know. It does not change much.
    • Octo-Pi has been installed,
      • created users
        • some Octo Admin's
        • a LMN common user
      • enabled Auto login by local network
        • any internal 10.1.10.0/24 will auto login with access.
        • Remote or outside will be view only, unless with user/pw.
      • enabled auto connect
      • Changed Web Page Host name to “LMN MakerFarm i3 Prues”
      • Limited haproxy to maxconn of 2. only lets two web pages, as not to overload Pi.
    • USB camera has been ordered.
      • Currently is trying Pi-Cam, very slow.
    • Printer setup modified for
      • temperatures
      • beginning and ending Gcode scripts
      • auto bed leveling code
    • OctoPrint has been updated from 1.2.4 to 1.2.5(stable) using the interface
    • Added the following plugins
      • Custom Control Editor
      • System Command Editor
      • Editor Collection
      • EEPROM Marlin Editor
      • Print History
      • STL Viewer
    • Added stub commands to control the lighting
      • Currently using M42 P4 S255 / M42 P4 S0
        • We still need a relay hooked up to this pin to drive a light.
  • Still needs done:
    • 3D Print an enclosure for the pi
      • currently using a stock case. But a better custom case to attach to MakerFarm is desired.
    • Need to investigate slowing down the FPS. Too much for Pi FFMPEG
    • More …
    • Write instructions on how to connect and print
    • Install and test Cura profiles so STL's can be sliced on the machine
      • Test Raspberry Pi B for slicing - may be a problem for larger or complicated parts
      • If too slow, slice before uploading or consider Raspberry Pi2
    • Install Pi camera on machine which might include 3d printing an enclosure for the camera.
      • Currently Duct tape and Wire is holding camera.
    • Add LED/Lamp for Camera
      • Drive it from Ramps either:
        • Using an M42 G-code and the octoprint command plug in creating a couple buttons should be easy

          • http://plugins.octoprint.org/plugins/customControl/
        • Other ideas include:
          • in parallel to fans
          • in parallel to Motors being energized
    • Consider all possible scenarios for overheating or loss of control
    • Address the issue of the PSU load which is not connected well and also may overheat nearby objects
    • A backup of the SD card should be done, and some sort of regular backup system should be in place so if something is ever broken we have a place in time to restore to.
  • Considerations:
    • LDAP authentication or equivalent for future https://github.com/foosel/OctoPrint/issues/594
