????????????

N9 g00 z0.01
.........
N20 g00 z0.1

^^This.

You are at Z.01 before the canned cycle and the first move you make inside it is Z.1 then Z-.94

Can't move different directions in Z.

N26 and N29 are going to cause problems too.

Thank you for the feed back. I started learning g code a week ago so Im very new to it.

As suggested, change to
N9 G00 Z0.1;

G28, without argument, may cause problem.
