Python Forum

Hi

total python newbie here

A friend has been using F-engrave http://www.scorchworks.com/Fengrave/fengrave.html

they supply the source code and he would to change the code that write the g code to file. I have identified the code below.
how would I change this so it wrote all the lines in (self.gcode) > then write a line with text "g68 x0 y0 r180" > then repeat all the (self.gcode) lines > then write a line with text "g69" > then write a line with text "m30" > then write a line with text "%".

hope this makes sense

many thanks
