This is a spare part! While the print head can be directly connected to the motherboard of a 3D printer, we recommend to use this as a part of 3D Printing KIT and connect to the printer via Control Unit. When used without control unit, this may need to change settings of your stepper motor driver. In case of questions please contact us.
