Servo Jumping On Initialisation

The dreaded jumping servo problem has arisen again - just today. All servos in the robot are HDD. The servo on port D0 now jumps after connecting, to about 35 degrees instead of 90 degrees. If I move the servo manually when turned off, the centre position is still 90 degrees, so the sprocket has not shifted. My INIT script has not changed. That...

Controlling Servos For Robotic Arm

Hello, I purchased this robotic arm (https://www.dfrobot.com/product-192.html#:~:text=DFLG6DOF%20is%20a%20bionic%20robotic,be%20rotated%20about%20180%20degrees) and wanted to control it via ARC. Should the servos be compatible? I also think it could have something to do my power adapter. I am using a 9V DC 800 mA adapter.

I have tried scripts I found in the community on here, but since it doesn't connect to a digital port they do not work. I tried editing some of the scripts to use a sound servo to enable RGB animator script, but it still...
