New Purelogic 4(6) axis CNC breakout board


Supply voltage: 12V, Max current: 200mA

Brand new PLD-based board have following main features:
  • Compatible with any LPT СNC software (STEP/DIR - Mach, TurboCNC, etc.).
  • Charge Pump support
  • Advanced PWM->voltage converter
  • 6 optoisolated inputs, 3 power outputs(high-current 6A/220V relays control)
  • Coolant pump timer
  • Motor connection by IDC10 or RJ45 jack
  • STEP pulse built-in test oscillator

  • One supply voltage is used for the whole circuit; board smooth start system.
  • Simultaneous control of up to 6 stepper/servo motor drivers.
  • Control signal buffering. All control signals from LPT-port of PC pass through current amplifying buffer cell (each contact current is amplified to 10mA). LPT-port signals are buffered to prevent failure of port. Board can be connected to any port with 3.3-5V logical unit.
  • Connection to LPT-port via standard DB-25M type or IDC-26 type connector.
  • Connection of external back-up LED for relay trip and optical inputs is provided.
