/**
 *
 * This is a starting-point to support the Makerbot Replicator series of 3D printers.
 * It's not functional because Marlin has limited support for some features.
 * Marlin will need the following augmentations before it will be supportable:
 *
 *   - Support for two or more MAX6675 thermocouples
 *   - Support for multiple i2c buses to control the MCP4018 digital pots
 *   - Support for one additional unidirectional SPI bus, to read the thermocouples
 *   - Support for an RGB LED that may work differently from BLINKM
 *
 * The MCP4018 requires separate I2C buses because it has a fixed address (0x2F << 1 = 0x5E)
 * The thermocouples share the same SCK and DO pins, with their own CS pins.
 * The controller interface port connects to a 3-wire shift-register display controller
 *
