According to this pdf for the TowerPro SG90 servo

http://datasheet.sparkgo.com.br/SG90Servo.pdf

Brown is ground
Red is positive
orange is PWM
in that order

according to the 1.1b user manual
http://reprapelectro.com/wp-content/...ser-Manual.pdf

according to page 58

you have to add the servo pins to pins.h with ifdef statements

so i would assume this would be what is needed to be added

Code:
#ifdef NUM_SERVOS #define SERVO0_PIN 22
 #if NUM_SERVOS > 1
 #define SERVO1_PIN 23
 #endif
 #if NUM_SERVOS > 2
 #define SERVO2_PIN 24
 #endif
 #if NUM_SERVOS > 3
 #define SERVO2_PIN -1
 #endif
#endif

page 48-49

using the motor ext pins MX1

pin 22
pin 23
pin 24

is needed


and according to the drawing on page 48, you need to swap pins on the servo to be

red power
brown ground
orange pwm


so far is my logic correct?


if it is correct here is my issue...

nothing happens when i issue M280 P0 S40


so... any ideas?
