- The 4 wire motor and OUT1, OUT2 and OUT3 are JST VH series connectors. They require a minimum of 22AWG wire (20AWG or 0.5mm2 recommended. Most NEMA17 size stepper motor wire will will not be thick enough. You will need a suitable crimping tool for the crimp pins, for example Engineer PA21 (use the 2.2mm jaw opening to crimp the bare wire and the 2.5mm on to crimp the insulation). Alternatively you can solder the wire to the crimp pin
- The default 5V power configuration is Internal 5V enable - jumpered, 5V->SBC jumpered (the Duet is powering the SBC) , SBC->5V* not jumpered. If you want the SBC to provide 5V to the Duet then remove the jumper from 5V->SBC and from Internal 5v En. Place a jumper on SBC-5V*. NOTE this bypasses the 5V protection and a fault on the SBC may damage the Duet.
- The two banks of Low Current outputs (OUT4-6, OUT7-9) can be separately selected to be powered by either VIN or internal 12V. Total 12V fan current draw must not exceed 800mA.
- The separate OUT0 Power in allows for a different voltage to be supplied for the OUT0 high current output (e.g for a large bed heater) If this is not required VIN power must be applied to both the POWER IN and the OUT0 POWER IN terminals for OUT 0 to be powered.
