Materials and Wiring Instructions
To connect the Raspberry Pi Model B to your Einsy Rambo board, you will also need six ~200mm male to female jumper wires.
Mount the case with the M3*10mm screws included in the spare bag onto the MMU Superswitch mounting holes already drilled into the frame. Wrap the wires coming out of the Einsy box with the extruder's spiral wrap, and ziptie them onto the Pi case to prevent them from interfering with the X-axis.
1) The Einsy Rambo's 5V regulator is not sufficient for powering the Raspberry Pi Model B, you will need a separate USB Adapter or 5VDC PSU. It may be a good idea to disconnect the 5VDC wire between the Pi and Einsy to prevent the Einsy being powered on by the Pi's PSU when the printer PSU is switched off.
2) Make sure your GPIO connections are correct! Refer to the official manuals and GPIO wiring scheme.
