I couldn’t find any affordable 5 axis machines. All of Roland’s machines are 3 or 4 axis. If your machining soft materials some of the desktop CNC Routers might be a good alternative. One thing you need to be careful of is not only the quality of the ball screws used but also that they have a usb interface. The market is flooded with older stepper motors that require older pc’s to run them ie > Win XP 32 bit.
After about a year and half looking I ended up here.
