Record the 3d print process.
This is the way I record my 3d printing, using a Raspberry Pi and its camera module. At Thingeverse I found an enclosure for the camera. A quick search reveals a lot of hits: Thingeverse raspberry pi camera.
I printed out housing for both the Pi and the camera, and mounted it nearby the 3d printer.
I'm using a script to contrl the camera to take a picture every second. This is the Python program:
import os
import time
from time import sleep
import picamera
import string
path ='/home/pi/images/'
loop = 1
camera = picamera.PiCamera()
def checkFolder():
folder = 0
global newPath
for _, dirnames, filenames in os.walk(path):
folder += len(dirnames)
print 'Folders: %s' % folder
newPath = '/home/pi/images/' + str(folder)
os.makedirs(newPath)
def takePicture():
currentNumber = len([f for f in os.listdir(newPath) if os.path.isfile(os.path.join(newPath,f))])
print 'Current files : %s' % currentNumber
newNumber = int (currentNumber) + 1
sleep(2)
completeFileName = 'image-%s' % newNumber
camera.capture(newPath+'/%s.jpg' % completeFileName)
sleep(3)
print 'Current files : %s' % newNumber
print '******************'
def main():
checkFolder()
while loop == 1:
print 'Open camera.'
takePicture()
print 'Close camera.'
main()
This program counts the number of folders in /home/pi/images and adds one to the number, then creates a new folder, with the counted number as the name. All images are stored in the new folder. This is repeated with a one second delay.
