GO Config is ok, so it's your karel program issue.
1. guess that .pc is background running? so condition will force the GO value...
2. replace POS_TOL 0.1 to a bigger value , e.g 1 and try again
Thanks for your response.
The point is the configured Digital Output Signals do not respond with corresponding Group Out Signal.
when robot is at home position, Group Out #2 signal Ought to be number 1 which means the robot is Home.
