Rick - per the quoted info above, it looks like you only need T1 (1/4" endmill), T3 (Engraving bit), and T4 (1/8" Stub drill, or center drill). I believe the order you want to use them is T3, T4, then T1 (you can verify this by opening the GCode in any text editor and scrolling through the code. You should see something like “M0 T3” or something to that effect at the beginning of the code, as well as when it transitions to the next tool. You could also use https://ncviewer.com/ to see the code and play through the cut). I want to say that when you start the program in GC, if you look in the window where all the GCode is running, it should tell you what tool it is expecting to use. I think it should pause as soon as you hit play to allow for a tool change. Once you verify you have the correct bit in, then you can hit resume.
