The ports look like the solder on them is good, it all looks very clean and they are not dull.
I was able to get it up and running on port 13 and all movements seemed to be working good.
I performed all of the preprogrammed skills, and it was balancing well as i tilted the ground under it
After about 20 minutes or so, the front left paw stopped working again and the rear left paw went straight out and started shaking.
I've moved the servo to port 11 now, and recalibrated all of them (i centered and zeroed everything and started over with leg calibration)
the rear left paw shakes as it moves into position behind all of the others, and the front left paw is not moving to the proper position. it is not extending out to touch the ground, stopping a few degrees short.
I'm thinking that the front left servo might be bad and damaging the ports? (i've confirmed that the two ports do not work with any servo any more)
I have no idea what is going on with the rear left paw, it did not return to center when i put it back in calibration mode, which would suggest the sensor may not be functioning.
Any ideas of what i can do? (sorry to be a burden, i'm sure you get tons of questions)
