1- fixed thanks, +264. I haven’t put up a new recommended size yet, so you must be seeing the old dimensions from somewhere. I would make your machine as small as possible paying particular attention to the leg and Z axis height. Bit are generally 1.5″ of usable bite so really anything over that is material height, more is not better.
3- well see I have a lot of it sitting here waitng for the build in different wall thickness’ well see if it is really worth it. I am going to guess for milling not worth it, laser picture engraving and 3d printing probably worth it, anything else conduit is fine.
8- I just recently added both sizes, took a note to fix this.
