Am having issues with my servo.
When i plug it in and power on, it moves to 0 degrees and it sounds like it's trying to move past it.
In pronterface when i check the angle with m280 p0, it returns 0.
Then when i try to move it to any angle, m280 p0 s100, it'll rotate it to that angle, then the USB connection to arduino dies & proterface connection gets broken. I need to unplug/plug usb to reconnect via pronterface.
Also, where do i connect the probe switch on a ramps 1.4?

i'll won't be able to go by the hobby shop anytime soon.
I connected a jumper on the pins just beside the reset Switch.
[reprap.org]
Based on that schematic, it's the 5V & VCC pins, just left of the reset switch.
Servo is connected to the first 3 vertical pins on the right of the reset switch.

Using those connections will work, but will give you big problems because there is simply not enough power available for many servos.
You risk loosing some big prints because of failure to supply the needed current.
The 7805 chip can be bought from most electronic supply shops and there are millions available online and through ebay. Not expensive.

I'm totally new to electronics and reprap. I was following a guide i found online to setup the servo. Thus I'm not aware of another way to hook it up.
What's the 7805 chip and how would i hook it up to the RAMPS & Servo?

Thanks alot!
I think i get what you mean.
Let check if this is right.
Remove my jumper that connects the 5V to VCC pin.
7805 - Pin 1 - Connect to 12v input.
7805 - Pin 2 - Connect to Ground.
7805 - Pin 3 - Connect to the VCC pin i just disconnected
Servo leave it as it is.

Awesome!
Will need to go find the 7805 chip. Will post back my results.
Thanks!

I think i might have a faulty servo.
Got the 7805 and a new servo just in case.
Wired the 7805 up with the first servo i was using. Now the USB connection doesn't disconnect, but i still hear the sound like the servo is trying to go past 0 (trying to turn but getting jammed).
When i issue any m280 commands, nothing happens.
Replaced the servo with a new one. I can control it with m280 commands. Though i still hear sounds like it's trying to go past 0, but it's much softer (first servo has metal gears, new one is all plastic)
Question: Occasionally the servo "jumps" very minutely, like a degree and goes back. When the steppers moves x,y, or z, the 'jumping' happens more frequently. Is that normal?

I just added a 7805 to my RAMPS board for the servo, as well as a switch to control the motor cooling fans. Now whenever I turn the fans on, the servo jumps about 10 degrees.

Make sure that the servo arm is in the correct position before you screw the arm onto the servo.
Best way to do this is to leave the arm off, andthen turn on your power and let the servo home, then attach the servo arm while in the home position.

It's not the arm that's hitting. My arm can rotate 360 unobstructed. Even without the arm, i can hear like the gears still trying to move even at 0.
What value disc capacitor should i try?

A video of the servo. You can hear the gears moving, when i move any servo.
