Ive Notice Something Wierd

 
#1

has anyone have this happen , after shutting down the power to ezb board .then power up again . when seems good i give command to look home .and servos move fast in wrong way then come back slowly to home position . then everything is ok as long i dont unplug battery pack.

#2

I assume it's because the servos don't know their position when you first power them on... I might be wrong on that though

#3

ive try everything i can think of , its like wierd Grin

#4

I have the exact same issue. I have a script at connexion which move some servos to a defined position. If the script is launched after a shutdown/power-up, the servos go crazy and move suddenly to an unexpected position, then they go to the defined position in the script. If I just disconnect the board and reconnect it (no shutting down), there is no problem... I am also puzzled...

#5

i think we need dj opinion on this too Grin

#6

I have just tried again and observed carefully what happens. It seems that all servo try to go to position 0 before going to the expected position... and as none of the servos is able to go to 0 (limit is more around 10-15), it gives a strange and scary result.
I agree, we certainly need DJ expertise...
