This is a detailed guide on how to convert a Makerbot 3D printer to use Ramps 1.4 board, external thermocouple, and reprap LCD controller. The conversion involves replacing the original electronics with new components, wiring them together, and installing firmware. Here's a summary of the steps: **Pre-Build** * Rip out the original electronics (Mightyboard, LCD interface, heater cartridge) * Purchase all the parts on the parts list * Leave the original wiring and connections for later use **Building** * Glue the 12V 30A power supply, Ramps 1.4 board, and external thermocouple board to the bottom of the Makerbot * Connect the components to their proper places on the Ramps 1.4 board using jumper cables * Wire the Ramps 1.4 board to the power supply * Mount the reprap LCD controller to the front of the printer * Run ribbon cables through the original hole to the Ramps 1.4 board **Optional** * Install an LED light board and connect it to the Ramps 1.4 board * Remove the old LED light strip and install a new RGB light strip **Firmware** * Build custom firmware using Marlin (download from GitHub) * Load the firmware onto the board using a USB cable **Calibrating** * Test the printer's movements and motors * Adjust the steps per mm and other settings as needed * Do test prints to ensure everything is working properly **Resources** * Utilize reprap.org for help with wiring diagrams, troubleshooting, and other issues * Download STL files from Thingiverse for custom parts (e.g. SD card holder) Note that this conversion requires a significant amount of technical expertise and patience. The guide provides detailed instructions, but it's recommended to have experience with electronics and programming before attempting this project.
