Tips and Tricks
Technical specifications (December 2016 edition)
Here is some information if you are new to printing, which I have discovered to be helpful.
Refer to the many videos on how to unbox and setup, on youtube.
Look at all the pages on this website to become familiar with the information available. READ THE MANUAL FOR SETUP/PRINTING!!!!
For assembled units, I would take pictures of all the settings on the LCD that Prusa setup so you have the details of what they chose. I would also measure the extruder screws with calipers to see how far out they are. Mine are at 13mm.

The first thing to do is install your software. You can do this before printer installation. Go to the Prusa Drivers website and download the full install. Find the section labeled Drivers and Manuals and download the Windows or MacOSX version. While you are there, download the Firmware as well.
On Windows, after software installation, you can click on your Start Button -> All Programs -> Prusa 3D.
Look at the programs/links inside that folder to become familiar with what is available. Make note of Slic3r, Pronterface, and Firmware Updater.
Plug your 3D printer into your USB port, turn power on, and open Firmware Updater (under the start menu).
The .hex file (1_75mm_MK2-RAMBo13a-E3Dv6full.hex) is inside the zip file you downloaded from the Prusa Drivers website.
Select the serial port. If you are unsure which one it is, unplug the printer and rescan. The port will now not be listed.
Hit the update button. This will update your 3D Printer. Check out the website help and a youtube video.

Version: 1.33.8:
C:\Users\Public\Documents\Prusa3D\Slic3r settings MK2\printer
Version: 1.34.0 Alpha:
C:\Users\USERNAME\AppData\Roaming\Slic3r
To test the dev release, go to: Prusa3d Releases and choose the version to install. In this instance, I installed the Slic3r-1.34.0-prusa3d-win64-full-201703301257.zip version. After you extract and run this file, download the settings from: https://github.com/prusa3d/Slic3r-settings and extract to: C:\Users\USERNAME\AppData\Roaming\Slic3r
Be sure to backup the current files before replacing them.
The version 1.33.8's ini files are located in: C:\Users\Public\Documents\Prusa3D\Slic3r settings MK2\printer

Pre-compiled hex files for all printers by PRUSA RESEARCH are available in hex_files folder.
Just clone the repo and flash it to the firmware.
Download and install Arduino; suggested and verified version is the 1.6.8 from:
https://www.arduino.cc/en/Main/OldSoftwareReleases#previous
If you also use Arduino for other purposes, it is suggested to use a stand-alone version rather than a system-wide install (e.g., use the "Windows" version instead of "Windows Installer"), and use it only for Prusa i3 MK2 firmware generation.
Clone the prusa3d/Prusa-Firmware (Branch: MK2) repository to a local path.
If you are not an expert git user, it is suggested to Download it as ZIP from:
https://github.com/prusa3d/Prusa-Firmware/tree/MK2
Due to name collision, you have to remove the Liquid Crystal library of the original Arduino installation. To do so, you may rename the "Arduino\libraries\LiquidCrystal" directory to "Arduino\libraries\LiquidCrystal_", or remove it altogether.
Copy the contents of the ArduinoAddons/Arduino_1.6.x directory from the downloaded firmware repository to the root of the installed arduino path.
Download the bootloader image from:
https://raw.githubusercontent.com/arduino/Arduino/master/hardware/arduino/avr/bootloaders/stk500v2/stk500boot_v2_mega2560.hex
Save a copy of it on each of the following directories:
Double-check that the file has the .hex extension and not .txt.
Copy and rename the file Prusa-Firmware/Firmware/variants/1_75mm_MK2-RAMBo13a-E3Dv6full.h file to Firmware/Configuration_prusa.h (note that you may have to use the 1_75mm_MK2-RAMBo10a-E3Dv6full.h if you have an older RAMBo board.
Load the Arduino IDE and select the RAMBo as target board from the Tools submenu. You are now ready to modify and build the firmware!
Make some modifications to the firmware.
For example, edit the Configuration_prusa.h file and edit (at your own risk):
You can now build the firmware:
You will find the exported binary in the Prusa-Firmware/Firmware directory:
If you encounter the "using typedef-name 'fpos_t' after 'struct'" problem, you either have a wrong Arduino version (need 1.6.8 - check Step 1) or need to manually modify fpos_t to fpos_t2 in the files SDBasefile.cpp and SDBasefile.h.
If you are using Linux AND using a cloned git repo, you'll encounter the "generate_version_header_for_marlin execute file not found in $path" error; download and install the script from the following website:
Wackerbarth/Marlin#1
You'll also have to make the script executable (chmod a+x path/to/file)
Upload the new firmare to the printer using the standard firmware update tool included in original Prusa firmware:
