Trouble with setting up ABL on Rambo board... help!
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?
Printer will print perfect...
