The lines that you want to repeat should be indented more than the
'while True' line.

In the code you posted, only the lines from:

     enable_servo()

to:

     print ("forward1x")

were indented more than the 'while True' line, so only those lines will
be repeated.

If you want the lines that follow them also to be repeated, then indent
then too.
