The offset is specific to your robot and no one elses. Because each of the servos may not be perfectly aligned, the servos will need to be calibrated.

To calibrate the servos:

1. Lie JD down on his back

2. Connect ARC to JD

3. Load the JD Project

4. Load the servo Fine Tune Configurator

5. Keep the "position" at 90 for all servos. Never change that.

6. Use the + and - for each of the JD servos to align the lever to be perfectly flush with the servo housing. This is the 90 degree position. The edge of the lever must be parallel with the edge of the servo.

7. Each servo used in JD is described on the right of the servo Fine Tune window.

8. Once the servos are all aligned to be 90 degrees, press the SAVE button and give your configuration a filename (such as JD 1)

From this point forward, every time you load JD, it will ask you for the servo Configuration.

I had to set up a few offsets on my JD last night but mainly for the legs (he was having a hard time walking) however in my haste I didn't hit the save button so I guess I'll be doing it again when I get another chance to play with him.

rich, once you have the legs calibrated, could you share a screenshot of it with me? i'm curious to see what the servo offsets are for some robots.

i will try that dj

i try it.but it get worse.he trows his arms backwarts.

left schoulder makes loud noise and gets hot

I'll make a video for you today that shows how to calibrate the servos

thank you dj.

may the calibration go up to 80 orso?

here's a pic

@nomad... Why did you set the offsets so high for D4, D7 and D9? D4 and D7 are JD's shoulders.... Maybe that's why he is "throwing his arms back"?
