The Dual Z-axis replaces the Y-axis/Z-axis to the Cyclone PCB Factory.
The machine uses MGN12H Sliding Blocks and nema17 stepper motor to move the Z-axis.
3 limit switches to check limits and positioning.
All the screws used are all M3 screws.

Electronics and Controller:
The controller is a CNC controller with 8 stepper motor controllers, 16 limit switches inputs, USB and SD capabilities. 
The linking PCB is used to get the power and control to/from the Dual Z-axis. Get it here. 
Under the Dual Z-axis, there is a camera mounted for downwards imaging.
