Go line by line and update it before moving on. You’ll need to adjust bed sizes, nozzle information, stepper information, everything. Once you do that, open it in the Arduino IDE and make sure you update your configuration.h file to match your current printer. If you don’t have Marlin, you’ll need to download the latest version of Marlin.

If you have the copy of Marlin that you are currently using, then open it in the Arduino IDE and move on to the next step.

Download the arduino IDE (quick google search for it).

You can watch the video above to see a walk through I did, or follow the directions below! Much easier to deal with, and enabling the EEPROM really simple to do! With EEPROM, you can save and reload values directly from the LCD screen.

Without EEPROM enabled, when you change a setting (such as your esteps, which are important to tweak when calibrating your printer), you have to connect the arduino to your computer and reflash the firmware.

The first step was to enable the EEPROM, a bit of flash memory located on the RAMPS 1.4 board. How does the arduino do everything it’s supposed to do? I decided to dive a little deeper. When I first starting 3D printing, the biggest mystery was the firmware.
