I looked at it though I am no help in that department, i was just curious. i am guessing you are running mm and the parts are pretty small? I was seeing feedrates F140 and F50. If in inches, that would be fast on any machine i run but they are hobby conversions. I did just run it in Mach as a simulation. I was wrong, you are in inches arent you? It is funny, I wonder with a lot of experience, do people reading GCode see the part as it will be made without the drawing? I am guessing so but I am so far from that point it isnt a concern for me.
