    Resizing the SD Card Image


    This can be something you want to do if you run out of space on the SD card on the Pi (which can be due to copying over a lot of models to print or several larger ones).


    The stock SD card is a 8gb model (no clue on the card class). I suggest using a 16gb or a 32gb card instead to give you a lot more space. You will want to know where your Pi is at on your network (you will want the IP address) so either get that from the Printer LCD display (if yours is correctly showing the IP address -- there are some router/subnets that confuse the displayed IP address) or look on your router web page for devices that have assigned IP addresses and find the one that matches your Robo machine name. Jot this down for later use


    Step1: Remove and backup your existing SD card.

    You need to be able to reach into the bottom of the printer so make sure the bed is at the top and then lift out the Bottom plate. The SD card is just under the Raspberry Pi and can be seen sticking out from the end towards the front of the printer. Carefully extract it (pull it out) and not which way the car is oriented. You can't get it back in wrong, but it will be easier to put back in if you know which way it is oriented.


    You should do this as soon as you get the printer in any case because a problem with the SD card can immobilize your printer and it takes time to get a new image from Robo. They are slightly customized so that each printer has a unique name. To backup the card use whatever utilities are appropriate for your PC/Operating system. You can on Windows download and install Win32Disk imager (free) and use it to backup and restore the SD card as needed. Save the copied image where ever you like. Run Win32Disk Imager and select the destination for the image and give it a name:

    Select the READ button and wait for it to finish.


    Step 2: Format and initialize a new card.

    Use a Class 10 SD card of whichever size you want (16gb. 32gb). Use the Disk imager to point to the file you just created and the mounted SD card and then select WRITE and wait for it to finish.


    Step 3: put the SD card back into the Pi and boot the printer.

    If there are any issues you can power down and replace your original card, but you should be up and going.


    Step 4: Expand the file system on the Pi

    The image was created as a copy of the original so the OS on the Pi will assume nothing has changed and the volume sizes will all remain the same. You need to tell it that it now has a larger disk. This is done with remotely accessing the Pi. You need to use something like Putty (www.putty.org) so have that downloaded and installed. When you run it you will then need to know the IP address of the printer noted earlier (the machine name MIGHT work for you, depends on how your network and router are setup, but the IP address will always work). Use Putty or something similar to telnet/SSH to the pi.

    Login with the standard Pi credentials (they have not been altered). You will need to know the IP address the printer has in order to make this work. Once you have logged onto it, open a terminal window and run raspi-config (sudo raspi-config)

    Once done, reboot it again and that is it. You have now setup the printer to use a new SD card and a larger filesystem for storing models and the like.
