Hello, my commit requared 2560 processor in config.h
// Default cpu mappings. Grbl officially supports the Arduino Uno only. Other processor types
// may exist from user-supplied templates or directly user-defined in cpu_map.h
//#define CPU_MAP_ATMEGA328P // Arduino Uno CPU
define CPU_MAP_ATMEGA2560 // Arduino MEGA 2560 CPU
For relays i was use 4 pins of MEGA for port C
+#define RELAY_DDR DDRC
+#define RELAY_PORT PORTC
+#define RELAY1_BIT 3 // Pin 37
+#define RELAY2_BIT 2 // Piin 36
+#define RELAY3_BIT 1 // Pin 35
+#define RELAY4_BIT 0 // Pin 34
Thanx for all.
