      Abusing, another piece of help, need to connect something, looks like a
      "charge pump" in order to start and stop the spindle motor, that is simple
      to use, if i can control the motor speed, the better it is.

      This looks like an option.

      I think i have to define an "output pin" linked to the charge pump.

      Thanks

      *CP RELAY2 PDF MANUAL*

      *The CP-Relay2 board, short for Charge Pump relay board uses the 12 kHz
      signal from the parallel port generated by the CNC software to operate a
      relay. Any piece of machinery that uses powerful motors can be dangerous if
      controlled by a computer that can be in an unknown state while being powered
      up or in a software crash condition. Using this relay to disable power to
      motors is a safety device in that it only switches the relay on when the
      software is running correctly.*

      *The board is able to take signals from a standard parallel port and switch
      power lines to stepper motor etc up to 12 Amps at 24V DC. The relay contacts
      are rated at 2400 Watts or 240V AC at 10 Amps or 300 Watts DC. If this is
      not sufficient it could easily switch power to the coil of larger
      relay/contactor, perhaps controlling a three phase motor.*

      *The board has two inputs one a standard relay board switching motors, pumps
      etc under software control. The other a charge pump circuit that can be set
      to normal operation if required. It has it�s own on board 12V regulator
      which has plenty of spare capacity to drive other circuits. The board has
      three LED�s one indicating power on the 12V rail a second and third that
      illuminates when the relays are activated. Power to the board can be in the
      range of 14V minimum to 35V Maximun.*

      *CP-Relay board is available as dual or single relay in Kit form or ready
      assembled*

      *Dual relay Kit Code CPR2K �15.50 or Built Code CPR2 �19.50*

      *Single relay Kit Code CPR1K �11 or Built Code CPR1 �14*

      *Upgrade Kit from Single to dual relay Code CPRUK �5*
