gnexlab controller card ver 1.0

This product is no longer available



  • Standalone No PC Connection Required
  • Based on the Arduino Diecimila ( Atmega 8 )
  • 2×16 LCD
  • two trim-pots (to set two separate temperature values, one for nozzle one for the build platform)
  • 2  Power Transistor Outputs
  • 2 Relay Outputs
  • 2 Thermistor Input
  • 1 Thermocouple input (AD595)
  • Can Be Powered With ATX PC Power Supply

This board is controlling and monitoring the temperatures of the hot end and the build platform and it works as a stand alone device with no PC connection. This is very important because Mach3 is not tolerant of any serial communication while it is producing it’s pulse stream to the motor drivers.
