how to go back a step in Mach 3

[tdoe151]

My problem is some times my torch fires but does not pierce and then it finishes the cut {the torch move the shape of the cut but torch is off} and then moves on to the next pierce. Can someone tell me how to go back to previous pierce and restart the program from there? Thank you for your time!!

If i remember right... when you restart in the middle of the gcode. Youll have to reset your Z height.
