Electronics and Wiring

For the electronics, you will need to crimp your own connectors. We recommend adding quick connectors for the printheads, to make removing the printheads for maintenance easy. In this example, 5x2 DuPont connectors were used for everything but the heater wires, which use a MOLEX style connector. Assuming you have prepared all wires as in the “Crimped Wires” section under “Bill of Materials”, please follow the guide below.

Attention

Wiring for the printer also requires some mains wiring. This should only be done by a certified electrician. The plans can be found at the end of this guide.
