@Nomad..... Good thing those servos are only $12... As Rich said... go back and follow the instructions step by step...

yeach really cute cheap robot.sofar am impressed by the servo,not getting hot. i have printed all on paper.fingers crossed.

when you save the calibration,is that saved to in jd?

can i calibrate one servo at the time.?

No, nothing gets saved to the ezb4 (except server/network info... as in what mode it's in, password etc)... Everything is saved on your PC.... For servo positions this is the servo configuration file... You can save more than one config file. You can load any config file you want when you open you JD or any other project....

is it first open ARC then power on jd? he still have the spastik move

Not that I am technical by any means, but on my demo unit I had a similar issue. Can someone give nomad better guidance on checking that the init script is "stand"?

I don't think it is his init settings... If the servos are all set to 90 his robot should more or less resemble a standing JD... He can tweak the offsets from there to get JD standing straight with his arms to his side... I think it might be the way he assembled JD...

On another note, when you first apply power to servos they sometimes act erratically until a position command is sent to them... Maybe that's what he is referring to "spastic"?

I'm about to recalibrate my JD. I'll post something clear, easy to follow and complete shortly.
