@dj how do post my project ? ty cory

On the left of the reply box, under the row of smilies and UBB code is Attach File... Let's do this the easy way...
Click on browse
Find your project file (were ever you saved it) and click open
Click upload
It's should then be attached to your post.
OR
Save it to the cloud in ARC (I don't have ARC at work so can't do pictures of that way)
thanks you i can do that
i just tryed it didnt post it, maybe i could email him my project
ty cory
genievoicerecogntion3.EZB i forgot hit upload sorry my bad ty cory
Here is my project : Wall-E.EZB
I hope it will help...
This sounds a lot like the problem I was having with my servo. When I would start up ARC for the first time the servo what slam all the way to the end of the rotation then come back to the position I wanted. I talk about it in my project. I did find a workaround. visit my project pages and you'll see a discussed. it's almost towards the end. let me know if this helps. synthiam.com/Community/Questions/2263
@Dave, It seems that we have the same kind of problem. However, none of my servos have "1" as a min position, but have between "15" and "35". Here is a screenshot :
I have made some observations that maybe may help :
1/It happens only after a shutdown/power-up of the EZB, not after a simple deconnexion or closing of ARC. 2/After Power-up, if I just load the project, connect to EZB and directly launch the following script :
Servos go suddenly to "0", then slowly return to asked positions
3/However, if I manually move one servo (with servo control) after connexion and before launching the script, all servo move to "0", except the one that has been moved!
I hope it will make sense for @DJ, because I certainly don't have a clue...
Do this...
If you set the speed before the init position, the servo is going to slowly move into the position you specified.
Also, keep in mind how a servo works. You can find more under the Tutorials section, I advise reading. It uses electrical pulses in a pulse to determine the position. When you power on and off the ez-b, electrical pulses are sent which are going to move the servo randomly. That is an inherit behaviour of the servo and how they work.
