What am i doing wrong?

Support Servo controllers and servos

hi guys
im using sub moving_wait instead of delay, and controling speed. when im running the script it runs all the way and then “shutting down”, giving the familiar “stack overflow/underflow” error.
i guess i should end the loop with a quit, but cant find the right place for it in the script.
this is the script:

Hello, am_sy.

You are only adding two values to the stack on the line above, but the frame_1_2_4 subroutine expects 3 values. This causes a stack underflow. I found this by removing chunks of code from your loop, and then testing it to see if the error still occurred.
