Foxy,

G code is line logigal. If you put X, Y, Z values on one G0 line Mach will execute them all at the same time. To do what you want, you need to do  G01 Z (Value) F (Value) This will feed Z into the material, then on the next line G01 X (Value) Y(Value) F (Value), this will cut from your starting point to the new X,Y.

Ask again in the Mach General Discussion forum if this isn't clear.

No, just every time you want the feed to change.

Foxy,

Certain G codes are "modal". This means that when you use them, they remain at that value or mode until changed or cancelled. Feed rate "F" is one of them. Now you know the magic word, search in the manual for the list of modal commands.
