Which servo port do you have the ds239 plugged into? Did you zero the servo first before attaching the faceplate lifting arms? Also Ports 1 , 2 are meant for faceplate driving servos, port 3 is for the lip servo if you have that enabled in the code. That said, there are a couple possibilities. The limited faceplate servo angle of articulation could be due to being plugged into port 3 which has a different control range arc since it’s intended for the lip servo (mk85) or if you are plugged into port 1 or port 2 you may need to alter the duty cycle for the ds239 since the Alisha boards are coded for mg90 servos as a default. In which case you should reach out to the Crashworks guys @umbral turret or @glass spade for guidance in altering the code on their GitHub page

The code will need to be adjusted for the duty cycle of this servo. We're working on it now. Stay tuned!

In the config.h comment out the line:
#define SERVO_TYPE GENERIC // Uncomment this line if you are using generic servos
un-comment the line:
//#define SERVO_TYPE DS239MG // Uncomment this line if you are using DS239MG servos
