Here are the steps to replace a damaged Arduino Board
To complete this, you will need a replacement arduino board, a phillips head screw driver, and needle nose pliers.
At access all 3 of the board mount screws, you will need to first remove the LCD Smart Shield from the Ramps board. It helps to number the ribbon cables with permanent marker before removing, in case you have to unplug the ribbon cables or the come off of the smart shield.
After you remove the LCD Smart shield, you will need to disconnect the USB wire connected to the Arduino board.
Once the LCD smart shield and USB cable are disconnected and out of the way. You will need to remove the 3 mounting screws holding the board in place.
With the board free, you will start to pry the Arduino board from the Ramps. You can use the pliers to pry the boards apart.
Prying the boards apart is a slow and steady race. You do not want to pry to much in one spot. Or else you run the risk of bending the pins on the Ramps Board. In addition to the top left section of the board, you can also pry apart on the bottom left and the top right corners. If done in equal amounts, the Arduino board should come loose with little effort.
Once you have removed the damaged Arduino, you can set that aside and line the new board's sockets up with the Ramps pins.
If you have the LCD Header pins aligned, the rest should match up. It is very important to make sure to not offset the pin alignment by even 1 set of pins. Otherwise you run the risk of damaging the Arduino and it will need to be replaced again.
Once everything is alightned, you can start to pinch the boards together. Make sure to slowly pinch around perimeter to ensure that none of the Ramps pins are bent in the proces.
Now you can remount the board using the 3 screws you removed earlier. When reinstalling the LCD Smart Shield, make sure to align all pins with the headers on the LCD Smart Shield, otherwise you run the risk of damaging the Arduino board and will need to replace it again. Once the board is mounted, the final step will be to reinsert the USB cable into the Arduino board.
If your replacement Arduino board came with the firmware installed, you are ready to start printing. If the board did not come with firmware installed, please follow this link
to install our latest firmware using the Cura Slicer.
If any of the other wires come loose during the replacement process, email firstname.lastname@example.org
