  • 4 x A4892 stepper drivers, capable of up to 2A per coil and 16 microstep control
  • 3 x High current PWM outputs to drive heaters and fans
  • 2 x temperature sensing circuits for thermistors


  • Ethernet connection to control your printer via the web interface
  • USB host capable socket
  • MicroSD card slot for standalone printing


  • Fully open-source free download
  • Automatic calibration of print surface and delta parameters
  • Smooth realtime motion
  • Internal webserver for access via ethernet, with  DHCP and netBIOS
  • Machine controlled via web interface
