I have just received my new JD this week and immediately with switching on I had a problem with the left ankle moving to to max position and jittering. I tried to compensate by adjusting the profile without success. It has now been confirmed that port 14 on the control unit is faulty... I temporarily plugged the left knee into port 14 and it goes immediately to max. I now have a burnt out servo in the left ankle and while everything else works OK I can't walk or do anything else which requires the legs. Can someone please contact me ASAP about what I need to do to replacement parts? Dave. @Bonepole mad sick confused
