this cnc using slider rod as support frame. the slider rod is about 10$ per meter for 25mm,the slider bearing is about 6$ each. These 4 rods will form a cage get a better result than use rails on one side and also cheaper. The 4th and 5th axis are using harmonic drive gear unit. They are expensive. The used parts i can get on Taobao is about 100$ each for CSF 14 . CSF 14 is a bit small.
