wiring for Prusa I3 M201 printer

Post by coby » Fri May 27, 2016 12:45 pm

I need to know the wiring for Prusa I3 M201,

1. extruder wiring: it has two extruders, In the processor board, there are three ports for extruders. If you are looking from the front, which port should I plug the extruder on the left side and which port for the extruder on the right.

2. heatbed wiring: the heatbed has six pin, pins 1 & 2 are label as + red and pin 5&6 are label as - black. However, the socket that connects the heatbed has the + and - reversed. What is the correct connection.

3. PSU wiring.: in the youtube instruction video, the red wires are connected to power unit pins 2 &3, yet the written instruction shows the red wires connecting to pins #1 &2. which version is correct.

4. Fan: which fan is FAN3

Thanks for your help.

1. E0 for the left extruder, E1 for the right.
2. There is no “+” and “-“polarity for heating wires.
3. You need to connect the red wires to "+V", the location of "+V" may be different because of the different PSU.
4. Fan3 is for the fan for control board.
