I am using two PWM outputs from a Netduino 2 to control two servos. One of the PWM pins works perfectly fine but the other doesn't work until I have touched it with an oscope probe. The probe doesn't need to remain connected or even grounded. Just a small tap gets it running.
I removed the pin headers so I could directly solder the wires to the PCB so perhaps I damaged something? It's strange because everything works fine after I tap the connection with the probe. Both servos are powered and grounded from the same rails.
