1. Pressing cycle start makes the machine move to machine coords Z zero (i.e. Z home switch)

2. After cutting out the part it moved back to machine coords X, Y, Z zero (i.e all home switches)

I'm used to Vectric posting code out which moves the machine to

The code posts out G28 (line 6, and last but 2 lines), which is moving the machine to machine zero. Here it is:

In the post processor screen for F360 I tried changing the 'use G28' option to 'no', but this just omits the G28, and looks like it will then just home above the feature just cut.

Any thoughts to get it to go to

Before I part with some hard earned pension, has any body got experience of this problem ?
