My Left Foot

When I power JD on his left foot is not aligned (both servos). When I connect it is fine only happens when I power on. When I go into diagnostic mode it goes to 90 degrees fine. Looks like I have two Servos that have a strange power on location.

Doesn’t do this with my other JD or SIx etc just this one. Any ideas how to fix this.

If the foot servo is not labeled HDD, that is not unusual. The original servos (and most hobby servos) will jump to a random position when powered up until given a ControlCommand() does (when you initialize with ARC).



@Alan wow you are good. This one came with 2 regular servos and not the new HDD Servos on one foot. Was part of Black Friday sale. I will need to go back and look and see if they said HDD or regular servos in description.


Turns out i receiced 4 feet in my revolution kit (but you are only supposed to get 2). My kit has 2 feet with HDD and 2 feet with regular servos. One of the ankles on one of my new HDD feet was broken. The thread on the plastic braket had stipped. I had this on another JD before and printed a new one (must be a common problem maybe it should be metal instead of plastic). This time since I had spare feet I just swapped out foot but replacement was the regular servo.

it was a good kit. just by adding some printed parts and 2 dev kits i now have a complete JD, six, roli, flipper and a spare bits and pieces bot.
