Need sample G-code with G33.1

Can anybody help me with sample code for say M16x2 20mm deep.

Need this so I can get functional PP and then produce tapped holes in upcoming tests.

Cheers
Bengt

Assuming that the tool is touched-off with the tap at the top surface for Z = 0, and if you want the hole at (10,10)

M3 S100 ; start the spindle
G0 X10 Y10 Z1 ; move to the start position and height.
G33.1 Z-20 K2

You can put the X and Y on the G33.1 line, but I prefer not to.

Thank you Andy,

will ask my friends at Dolphin Partmaster to fix the PP for me.
