The servo is used to drive a servo that should lift and lower the pen. You need to make sure the servo pins are powered as by default they are not. To power them you can jumper the vcc and 5v pin located near the reset button on the board. The software uses servo 3 which is the farthest set of pins in servo block from the reset button. You can then click on the pen up and pen down buttons in the gui to test the servo.
You can adjust how far up and down the servo moves with the values in the default.properties.txt file the default values are
servo.downValue=1500
servo.dwell=250
servo.upValue=2350

Thanks Rick! The jumper is the missing piece for me. Will try tonight! |

Got it working, thank you!
The jumper location is completely different on RAMPS 1.6
Here are a couple marked up images of where I found it.

More questions from a n00b, sorry. There are references to servo settings in the processing sketch and in the RepRap firmware, but it's not obvious to me how to hook up the servo to my RAMPS
