Sample of Octoprint stats for almost 2 months.
The failed prints are those that needed to be cancelled during mid print for various reasons.
Little Printrbot keeps chugging away.

in1. SSH to your RPi using either Terminal or an utility like Cyberduck with username of “pi” (if you haven’t changed the default username) and your password.
2. Then enter following commands:
cd /root/bin sudo nano webcamd
3. Then look for the following entry
camera_raspi_options="-fps 10"
4. Comment out the existing line in case you would like to revert back the
changes. x & y options give the resolution. The RPi camera can do 1080p30
but 720p is good enough for me.
camera_raspi_options="-fps 10 -x 1280 -y 720"
5. Press Ctrl + O, Enter to save and then Ctrl + X to exit
6. Reboot with:
sudo reboot

inMy PrintrBot z-axis got misaligned when I inadvertently left something on the printer bed after sending a new print to be printed. Did not realize till I heard the grinding noise. I cut the power but it was already too late. Upon restarting, the Z-home was almost an inch away from the bed.
Watched couple of videos on z calibration. Manually brought down the hotend till it was almost touching the bed and then fired up the auto leveling wizard. Tried a cube print first to see if it would turn out to be ok. The resulting cube was 0.3 short all around (from earlier reference cubes printed).
The M501 command showed that the Z axis was compensated almost -1.25.

Took a wild guess and adjusted the Z-axis offset by 0.5
// Reset Bed probe offset (mm)
M212 X25.00 Y0.00 Z-1.20
// Save settings
M500
Tried cube after the reset the offset, much better z-axis 3.01 to 3.02 all around.

NASA has made available various 3D printable models that can be downloaded and printed by hobbyists. Wanted to try out Curiosity Rover on my PrintrBot. The supplied models come in two sizes. The large is too big for PrintrBot Simple. So decided to try out the small version.
Body, Arms and Legs were printed with Hatchbox White PLA. While the wheels are printed with Toner Plastics Red PLA. The settings are same for both of them.
PrintBot Simple Metal with Heated Bed
Filament : Hatchbox White PLA, Toner Plastics Red PLA
Layer Height : 0.1984
Print Speed : 45
Print Temperature : 195
Bed Temperature : 65
Curiosity is a car-sized robotic rover exploring Gale Crater on Mars as part of NASA’s Mars Science Laboratory mission (MSL). Curiosity was launched from Cape Canaveral on November 26, 2011, at 10:02 EST aboard the MSL spacecraft and landed on Aeolis Palus in Gale Crater on Mars on August 6, 2012, 05:17 UTC. The Bradbury Landing site was less than 2.4 km (1.5 mi) from the center of the rover’s touchdown target after a 563,000,000 km (350,000,000 mi) journey.The rover’s goals include: investigation of the Martian climate and geology; assessment of whether the selected field site inside Gale Crater has ever offered environmental conditions favorable for microbial life, including investigation of the role of water; and planetary habitability studies in preparation for future human exploration.

Was looking into 3d Scanners. Makerbot makes one that is $799 but did not feel like shelling out that much and their approach to open source. The Ciclop is a open source design by a spanish company BQ who also sells a kit by the same name. This kickstarter takes their design and has made it more affordable. This is ofcourse based on the assumption that the backers will be printing their own 3D parts for the scanner.
$99 gives you everything except for 3D printed parts.
Thingiverse had the the 3D printed parts published by BQ.
