5 Axis CNC Interface Adapter Parallel Breakout Board For Stepper Motor Drivers

  This Parallel Port Breakout board allows a computer's parallel port to control all the signals needed for controlling stepper motors on a 5 axis CNC machine.  5 inputs allow for limit switches or e-stop switches.  This board can be used on any PC with a parallel port, or it can be used with the Raspberry Pi Parallel Hat on a Raspberry Pi.   The 3D printable mount is available here: Pi Parallel Hat and Breakout Board Stand v8   Product description: Size : Approx 90*61*15mm Cable Length : Approx 50cm Weight : Approx 85g (3oz) Features : Full support for MACH3 on Windows and Linux CNC (PC or Raspberry Pi). Both utilize the parallel port control. USB power supply and peripherals powered phase separation to protect computer security.   Peripheral wide voltage input,12-24V. All of the input signals are opto-isolated.  Output port P17 controls the relay.  This is most commonly used for spindle on/off.  Please be careful when turning DC power on and off and use an external
