Raspberry Pi from SD to USB

How to switch over from SD-card to USB-attached device (USB thumbstick, USB enclosed SSD or HDD, etc.) to have more durable storage option.

Steps

1. Connect USB device to your RPI

2. Make sure USB device visible by the system

# The peripheral clock is 80MHz or 12.5 nanoseconds per clock.
# The smallest precision of timing requried for neopixels is
# 0.35us, but I've decided to go with 0.05 microseconds or
# 50 nanoseconds. 50 nanoseconds = 12.5 * 4 clocks.
# By dividing the 80MHz clock by 4 we get a clock every 50 nanoseconds.

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:

1. Setup Google Drive / OneDrive / Dropbox on every machine you want to sync the Cura settings on
2. 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
