Duet 3 Wiring Guide
Duet Wiring Instructions
This is a guide on how to wire the Duet board for your printer. Once you have mounted the Duet 3 and 24v power supply to your 3d printer you can began to wire the Duet 3 Mainboard. I’m using the Duet 3 in standalone mode so I won’t be covering the Raspberry Pi.
Power Supply
Connect the Black wire into the “L” terminal Connect the White wire into the “N” terminal Connect the Green wire into the Ground terminal The wire colors meet US color standards for AC. Colors. The positive wire from the power supply goes to the terminal marked +. Do not solder the power supply wires because the heat generated from the current can melt the solder causing the connection to become loose. Duet3d recommends to use bootlace ferrules on the end of the wires and to re-tighten the terminal block screws after doing the first few prints, because heat generated by the high can cause them to creep and become loose.
Connect the terminal block labelled POWER IN to your power supply Make sure to get the polarity right and the wires you use are of proper gauge size to carry the current to supply the bed heater and electronics.
Letters or numbers to designate coils.
The standard is A+,A-,B+,B- (or B-.B+,A-,A+) on the labelling of Duet3d boards.
