This extruder controller card is a temperature monitoring and PID temperature controller for 3D printers. If you have a desktop CNC machine you can easily convert your CNC to a 3D printer with this controller card. You can also handle your temperature related tasks of your 3D printer with this card without the need of a computer.

You can set both the extruder temperature and the heated bed temperature with on board trimpots. You can read digitally your set temps and sensor values from the LCD. You can directly connect your heating elements to the board. High Power MOSFETS can handle your current requirements.
