Hello Mike,
You may have to define your working plane before the "G01 Z-1.20", so
the machine knows where the starting point is in the Y-Z plane before
continueing with the arc???????
I also agree with the use of "K" for Z rotation & redefining Z-1.20
is not necessary, but it shouldn't hurt you if your in the right
plane to begin with.
Hope this helps,
Tim Bostic
