I agree with Dennis. Going slow never hurts unless it is in plastic. Then you melt things including delrin. You are very lucky to have the area available to use coolant. This will help with tool life and finish. Also lets you go faster when you get use to the machine. Like Dennis, I have over 25 years of CNC and manual machine experience to draw from. Even have my own machines but no area to use coolant, so I go slow to make my parts. Good luck with your mill!!

First run on a new program, or even setting it up again later is always a good time for caution. Saves tools, vises and dirty underware! I slow it all down and often single step through so i can read code as it spools and make changes if need be. Been doing it as a business since 1998, and sometimes use Mastercam to produce code, but usually write it out of my head.

You have a very nice finish on there. Doing great.
