In this video I show how to edit your g code so you can resume a project that you had to stop for some reason, like the bit broke off. And if you are 1 hour into a 2 hour carving you really do not want to start back at the beginning.

This is one of those things that does not come up very often but is good to know just in case. I am using NotePad++ to edit the gcode. It is not hard to do as you will see. Will Winder of UGS will be adding a tool soon that will do this for you, which will make it even easier. But being a DIYer I like to know how things work.

To add the G Code Language to Notepad++, this is a good tutorial.
