I’m using a Rambo 1.3 board instead of RAMPS. The firmware is mjrice’s most recent Wilson firmware.
I have the autobed leveling working with the exception of the servo. Reading around the internet I’ve learned you have to connect to the PWM header, and change servo0 in pins.h to pin 5. When the printer is turned on the servo gets really warm but never moves. This makes me think it’s getting some sort of signal, but not the signal I’m expecting.
Here is how I think everything should work (but doesn’t). If someone has any experience with this or can point me in the right direction I would appreciate it.
SERVO WIRE | | | GND 5V SIGNAL PWM HEADER ON RAMBO | | | | | | 5V GND PIN3 PIN4 PIN5 PIN6
So I have:
Servo 5V (middle wire) to PWM 5V
Servo GND to PWM GND
Servo SIGNAL to PWM Pin5
Here is an Image that I hope explains what I wrote above.
