/**

|
|
* 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
|

/**
|
|
* Rev B 2 JAN 2017
|
|
*
|
|
* Added pin definitions for:
|
|
* M3, M4 & M5 spindle control commands
|
|
* case light
|
|
*
|
|
* Corrected pin assignment for MOSFET_B_PIN pin. Changed it from 9 to 11. The port
|
|
* number (B5) agrees with the schematic but B5 is assigned to logical pin 11.
