First Tool Path

[Alex Fraser]

I had to figure out a post processor to get it to give me some G-code.  
I used the generic one for LinuxCNC and I got code!  I'm not a wiz with 
G-code so I have to slowly go through it re remembering what each line 
means.  The "Nxx" is for line number and can be left out.   I would have 
to adjust all the feed rates for my tiny Sherline mill.  One problem I 
have is getting the machine's 0 points in X, Y and Z to match the parts 
0 X, Y and Z .  As a rule the code to do that is in every program.  You 
bolt the part to the table, then set zero and if you know what you are 
doing that zero is the zero in the program, tis a mystery....

Attached is a txt file of the code as output from Fusion 360.
