The mill had to be slowed down enough so we weren't breaking bits, but then the enclosure took 45 minutes to finish. Then, we only got about 5 enclosures finished before a bit would break, and the bits were like $35 a piece. This is after it took me about two weeks to figure out the cad/mill program and got it calibrated to work properly and make it repeatable.
All that being said, I'm really excited about the aesthetic direction we are moving toward. Can't wait to share with you guys!

Are these the typical pressed alu cases under that nice finish? If so, what router do you have? Not trying to dissuade you from changing it up or anything but we also engrave in house with a fairly inexpensive table top router and i have it down to about 3-5 mins/piece depending on the amount of engraving. I can use 600mmmin (~24 ipm?) feed rate ok, no coolant. Feeds and speeds is a bit of a pain in the ass to figure out, but all to say better than the times you quoted are likely possible on the machine you have should you ever venture back....
looking forward to see whatever you try next!

any advice would be super rad, i would definitely consider trying it again in the future.
as an aside, i am such a huge fan of the count to 5. currently trying to figure out how to budget one into my life. so damn cool.

Ya definitely hit me up if you want via email if you try again. We moved workspaces recently and I finally have the cnc back up (I have 2 actually), soon I will be engraving for the current run so maybe i can make you some videos of the setup etc when we get there, with whatever comments I can provide. I found a lot of info online in general but also there is not that much regarding "pressed" aluminum, other than it is not a pleasure to machine. I really didn't know shit about cnc stuff when i bought my first cnc and also spent a lot of time breaking bits and getting poor results, it's always improving though, slowly. All to say i can definitely relate to your frustration when I read your post. It is also a lot of effort even when it works compared to i imagine silk screening, it's just that it can work better than i get the impression it is for you.
