I too am having problems along these lines with alignment and will patiently watch the outcome of this thread.

I have also a number of other issues, such as a head serve doesn't move the head up and down, testing with other ports indicated that the cervo is dead.

The spastic movement of the cervo's when it powers on does seem normal, but at the same time even after calibration in my project the robot fails to walk properly. or do the other programmed commands properly.

On top of that I have a burning smell coming from it, and loud cervo noise that will not go away once the software connects to him. (no noise before software connects)

The claws with no amount of calibration will ever close, they aways want to open wider and crush up against the arms.

Richard R has been asking this, the brackets come assembled onto the cervo. has anyone taken it apart and tried to adjust the cervo physically by replacement of the bracket to the curve assembly.

It seems to to me that there maybe an assembly problem at factory, and was wondering if anyone has tried to physical repositioning to correct this. (before I dive into that myself).

Also; is that burning smell normal? its very pronounced.

i removed averything from ARC and install it back.huge diff. then as you say i lay the arm beside jd.and connect.i didd a calibration off one foot. to see if he remembers it.disconnec&connect again and he did rememmber his foot. so i adjust all brackets when he's connected,and sofar he stands almost perfect. he's now batt charging.i bin doing all day offsets,include bioloid c-type. jd is just similar.in some cases like my cheap pc you have to remove the brackets, while he's connected and reposition them.it looks very good,soon test original poses, dj has made.i know for sure the brackets has to comes off,the horn or axel must move, freelee.if you dont do that,the serov's getting rapidly very hot.if they are not standing, in free rest position and you have to do a pose the servo has twice as much work, bioloid chuts down the servo in minites.i did weeks offsets from bioloid.

rr thank you

here an update.ID-18 / ID-2 / ID-3

dont hold there position as written on the calibration page.

i would say tree bad servo's

ps dj if you read this, plzz your idea

looks like the ARC dont read the calibration page.i have to adjust avery time i connect jd.

if you save the calibrations after you get it set, it will start prompting you for which calibration file you want to load when you load an ARC project.

hi D

yes ARC load the calibration page,but jd keeps spastik when turn on. he is not spatik when i connect to ARC cause i made one off my own. the ecample from dj works bad for me.so i have to get jd in good possition by just turn him on.

Nomad, I provided you with a step by step guide on how to calibrate JD, how to save the servo profile and how to prompt when project open to choose a profile. Nobody can do any more that that to show you what you must do.

I have also provided you with an explanation to the servo movements when powering on, this has nothing to do with ARC, it has nothing to do with the EZ-B it is due to the servos moving slightly when powered on, this is the same for all servos, all controllers, all software.

The example JD project is the same for everyone. It works perfectly fine. I have been using it for the last few days without any issue what so ever.

rich here it doesn .why .jd does lot more then little move. he pulls his ezb- out. i exsplained also many times ,the problem is jd doesn pose like the calibration page. i have to reset avery time i connect. iff there nothing anybody can do !well then its over for me. its not normal when i turn on jd averything flying arround. also the ezb4 doesn click in the housing,the connection falls out . all make a last post,then its goodby mad
