⬢Place the Extruder-idler-mmu2s in place and secure it using a M3x40 screw.
⬢Don't tighten the screw too firmly, it serves as a shaft for the idler. Check that the idler can rotate freely (the range of the movement is small).
⬢Use the M3x40 screw with the spring to introduce tension to the Extruder-idler.
Hold the Extruder-idler on the other side, until the screw reaches the nut. Since there is only one screw, you need to introduce a large force. The head of the screw, should be aligned or slightly below the surface.
⬢Gently twist the sleeve to make it smaller and tighter around the cables and slide the sleeve towards the extruder.
⬢Take 3 zip ties and insert them into the lower row of holes on the cable-holder.
⬢Twist the sleeve again (without twisting the cables inside) and tighten the zip ties.
IMPORTANT: Cut the remaining part of each zip tie using pliers as closest to its head as possible. Note the correct position of each zip ties's head (slightly off-centre to the left).
⬢Use two zip ties and push them through the upper slots on the cable-holder. Add the cables from the hotend and use the channel in the printed part to arrange them properly. Tighten the zip ties, cut the remaining parts.
⬢Don't worry about the cable, we will connect it later ;)
⬢Checked everything? Let's move to the MMU2S unit assembly.
