Breakout Board

Parallel port breakout board, Fully buffered, specifically designed for PC control of CNC machines

All independent inputs opto-isolated and fully buffered parallel port breakout board designed for control of CNC machines from PC based controller like Mach3, TurboCNC, EMC2, KCAM etc.

Fully assembled and tested Parallel port breakout board for interfacing your CNC machine to computer parallel port. All outputs are fully buffered and inputs are optoisolated, filtered for noise and buffered.The CNC parallel board is specifically designed for CNC control as there are features like on board charge pump circuit for saftey, 2 outputs are buffered twice separately and connected to independent terminals to enable hardware slaving of two stepper motors in parallel if needed in gantry style CNC machines.

The chage pump circuit can be disabled and the output pin can be reclaimed for other use if not needed. We have also provided LED indicators like CPGood (charge pump good), Relay ON and Estop OK. All of the above 3 signals can be reclaimed and used for any general purpose if needed making the mach3 breakout board flexible enough. Change pump circuit operates from as low as 200Hz to more than 15 KHz. On board rectifier and filter is provided so any AC/DC supply from wall adapter can be used to power the board.
