+* CNC PC: a Linux machine running the LinuxCNC Software and sends out commands via Parallel Port
+* G4: a old Apple G4 Case holding the stepper drivers and breakout board
+* Stepper Driver: Each stepper driver controls one stepper. There are 5 Stepper Driver in the G4: 2x X, 1x Y, 1x Z, 1x A (currently unused)
+* Breakout Board: Is used to "convert" the parallel commands to a different protocol that the stepper drivers are using. It controls also the spindle speed by sending an appropriate signal to the VFD
+* VFD (Variable Frequency Drive): This Box controls the Spindle. It has a output of 100 to 400Hz on 3 Phases and gets controlled by the Breakout Board.
