Greetings, so with my spindle I got with my 5Pro 2x4 last night I was doing a project that Carbide Motion 3d gave me an estimated time of 4 hours. While I was running my material with my 1/4" down bit, I increased the feed rate all the way it could go to see what it can do. My time went from just over 4 hours down to just under three hours. No issues, no tare-out not binding etc it was impressive. Now I am not going to run like that all the time, but I also feel your feed rate needs to be adjusted based on the type of bit you are using like I would not try this on an upcut bit. I would only do it on a down-cut bit. But that is my opinion and I feel this is a good subject to talk about.
