Making progress here. Finally got ball screws last week and spent the weekend getting the inserts into the profile (the fact that Kinitic supply two types of inserts is deeply annoying). I also built the DIY version of @Pyronious awesome board which was fun. Next job is greasing the ball joints and assembling the actuators. I'm a little nervous to do the wiring on the servo's / controller's so waiting for my CTO to help me with that to help me avoid frying parts / myself.
