Ok i found the issue. There is only one servo output working.. the first one.  I think i found the right PWM values. / range. Im not really getting the angle / pwm range . when you choose an angle of 700 it will be at max at 700 if you choose 800 it will be at max at 800. Its more like how far you think it is and choose the richt angle? Im now at 800 .. also because all motion files are 700 at max. So there is some room adjust some joints / positions 

for some reason from neutral position to negative angle is always less then to the positive one.  For now im just adjusting the jointcontroller.cpp angle_min / angle_max positions to get even angles on both sides. Dont know if that is the correct way? 

Lots op questions . Robot is working great now .. i just want to understand and if im doing it at the right way.

Im trying to get it work... but with no success. I have uploaded the sketch. Then im making a serial connection. Im pressing "m" or "p" key all i get is: output : 528 (internal = 495) . i dont know what to do now ? When i hold the m or p key the numbers go up and down but nothing happends. Am i doing something wrong here?  Please help me out.

Hi Guvalif, Thank you for your anwser. I will try and get back to you. Im new to the arduino stuff but im a quick learner. Im not sure if i understand the position of the joints. Are you talking about the home positions you set with the control server?

Im trying to determine PWM_MAX and PWM_MIN for my es08MD II servo's. Plen2 is now clapping againt his belly. The arm is not getting the right angle.(Shoulder pitch) It needs to go higher, so i think i have to change the PWM values? I have really no clue wich values i have to use. Angle_MIN and Angle_MAX are set to 800. How to get the right pwm vaules ? Thank you. I do not know how to research with the pwm_checker.ino. Do i have to upload the sketch with the jointcontroller.h and system.h file and watch the serial monitor or something?

Hello , I build a Plen2 robot with es08MD II servos. Do i need to change something in the firmware to use the full servo angle?

Thank you.

Best regards,
