    Friends..
    G32 is for threading...
    not for tapping
    You must use G84 or G88 for tapping
    Format for tapping similiar with drilling
    T0404
    G97 S350 M3
    G0 Z20. X0.
    Z2. M8
    G84 R1.
    G84 Z-65. F.... ( feeding is pitch ) base on you use G99
    G0 Z2. M9
    G28 U0.W0 M5
