Install ImageMagick from source on Ubuntu 14.04

Note

These notes were for a job I am no longer at and are very dated. Please go to the imagemagick website for updated instructions.

The version of ImageMagick that is installed when you run apt-get install imagemagick on Ubuntu 14.04 is older than I would like.

$ convert --version

Syncing Cura Settings & Profiles Accross multiple devices

I use multiple devices to control my 3D printer and it's alwys a hassle to move changes on profiles etc. between those machines leading to situations where I use an old version of my profiles to print a part because I just forgot to update it.

Here is how you can sync Cura settings between multiple devices:

Setup Google Drive / OneDrive / Dropbox on every machine you want to sync the Cura settings on
Go to the following location and copy the folder called cura to any convinient location inside your Google Drive / OneDrive / Dropbox folder. You can also rename the folder form cura to somthing else, I called mine Cura Settings.

Windows: %userprofile%\AppData\Roaming\cura

	# Scanner i2c en MicroPython \| MicroPython i2c scanner
	# Renvoi l'adresse en decimal et hexa de chaque device connecte sur le bus i2c
	# Return decimal and hexa adress of each i2c device
	# https://projetsdiy.fr - https://diyprojects.io (dec. 2017)

	import machine
	i2c = machine.I2C(scl=machine.Pin(5), sda=machine.Pin(4))

	print('Scan i2c bus...')
	devices = i2c.scan()
