+/**
+ * Rev B   3 JAN 2017
+ *
+ * Details on pin definitions for M3, M4 & M5 spindle control commands and for
+ * the CASE_LIGHT_PIN are at the end of this file.
+ *
+ * This started out as an attempt to add pin definitions for M3, M4 & M5 spindle
+ * control commands but quickly turned into a head scratcher as the sources for
+ * the revisions provided inconsistent information.
+ *
+ * As best I can determine:
+ *   1.5.3 boards should use the pins_ULTIMAKER.h file which means the BOARD_INFO_NAME
+ *      define in this file should say 1.5.3 rather than 1.5.4
+ *   This file is meant for 1.1 - 1.3 boards.
+ *   The endstops for the 1.0 boards use different definitions than on the 1.1 - 1.3
+ *      boards.
+ *
+ * I've added sections that have the 1.0 and 1.5.3 + endstop definitions so you can
+ * easily switch if needed.  I've also copied over the 1.5.3 + LCD definitions.
+ *
+ * To be 100% sure of the board you have:
+ *   1. In Configuration_adv.h enable "PINS_DEBUGGING"
+ *   2. Compile & uploade
+ *   3. Enter the command "M43 W1 I1".  This command will report that pin nmumber and
+ *      name of any pin that changes state.
+ *   4. Using a 1k (approximately) resistor pull the endstops and some of the LCD pins
+ *      to ground and see what is reported.
+ *   5. If the reported pin doesn't match the file then try a different board revision
+ *      and repeat steps 2 - 5
