Just my opinion, but 200ipm is pretty poor performance when you are paying $7000+ for a 2x4 machine.
The Camaster uses WinCNC, and comes with a PC, monitor, and V Carve PRO. This is probably $2500-$3000 of the price difference.
The Axiom is a table top machine, where the Camaster is a full floor standing machine. Axiom charges $650 for a stand, which is not needed with the Camaster.
The Axiom uses a Chinese spindle and VFD, which can be purchased for as little as $325, about the same price as the Milwaukee router the Camaster comes with.
If you actually compare apples to apples, the cost is not that much different, and you get a lot more performance from the Camaster.
The CAMaster machines are faster. The SR34 is 500 IPM and the SR24 is 350 IPM vs the AR8+ at 200 IPM. All things equal, is the SR34 really going to cut out my parts in less than half the time? Sure, the machine might be capable of cutting at 500 IPM but if solid wood and Baltic Birch plywood can only be cut at a maximum 250 IPM, the speed is much less impressive.
As Ted mentioned, it really depends on what you are doing. You should be able to easily cut baltic birch at 300-400ipm, depending on depth of cut and tool size.
Doubling the rapid speeds can save considerable time for some jobs.
As I said, 200ipm is very slow. My 15 year old MDF and skate bearing machine can cut at 180ipm. It cost me $700, and is bigger than the Axiom.
