Swapper3D Instructions

Wire the Arduino Controller

Turn off and unplug the printer

  1. Turn the power switch of the printer to the OFF position (yellow arrow)
  2. Unplug the power cable from the printer (Green arrow)
  3. Unplug the power cable from the wall (Red arrow)

Connect wire extensions to power

Instructions:

  1. At the bottom of the printer, where the Swapper3D power wire comes out the right side of the printer (This is the wire you previously connected to the Einsy control board, or the printers power supply),
  2. Using a small length of scotch tape (or similar), wrap the tape around the power wire a little bit before the connector, double the tape over so that it sticks to itself,
  3. using a permanent marker (preferably Red since it’s a power connector) write the letters “PWR” on the tape,
  4. then repeat this process for the power Extension extension (blue arrow), this wire has male connectors on one end (orange arrows) and stripped wires on the other end (green arrows),
  5. Plug the power extension wire connectors together with the power wire connectors, connect the Black wires with each other and connect the Red wires with each other.

Add spiral wrap to wire extensions

Instructions:

You may have different numbers of wires coming out from under the printer that are for the Swapper3D. That is ok. You just need to wrap the wires that you have already installed as part of this guide.

  1. Using the 6mm (Outside diameter)  spiral wire wrap,
  2. wrap it around the power extension wire,
  3. wrap until there is 4 inches from the end of the wire,
  4. then cut off the extra spiral wrap

Pro tip: It’s easy to apply the spiral wrap if you wrap the first couple inches on, then simply twist the unwrapped end of the spiral wrap and it will twist on the the wire.

Twist the wire ends together

Instructions:

  1. Find one of the short wires with both ends stripped(pink arrow),
  2. Pull the plastic off  the ends of the wire (green arrow)
  3. Twist the black short wire to the black wire of the power extension (it’s ok to pull the red and black wires apart a little more if you need)
  4. Twist the red short wire to the red wire of the power extension

Pro tip: Use a pair of needle nose pliers to twist the wires, your finger tips will thank you.

Open the Screw terminals

Instructions:

  1. Locate the INPUT for the lowest psu (green arrow) on the back of the Arduino bracket
  2. Using a small flat bladed screwdriver, and turning the screws counter-clockwise,
  3. Loosen the input screws terminals most of the way by turning the screws   (yellow arrow), keep the screws threaded into the terminals though DON’T Remove them all the way, you just need them loose enough to get the wires into the terminals

Connect power wires to psu input

  1. The terminals are labels by white letters printed on the PSU board (Red and Black arrows)
  2. “IN+” Plug the Red twisted wire into the “IN+” positive screw terminal (Red arrow), this is the port furthest from the bottom edge of the PSU board
  3. Tighten the screw
  4. Plug the Black twisted wire into the “IN-” negative screw terminal (Black arrow) this is the port closest to the bottom edge of the PSU board
  5. Tighten the screw

Connect psu 1 (Lower Arduino PSU) input to psu 2 power input

  1. Connect the free end of the BLACK short wire to the negative “IN-” screw terminal of the upper PSU
  2. Tighten the screw
  3. Connect the free end of the RED short wire to the positive “IN+” screw terminal of the upper PSU
  4. Tighten the screw

Plug in, and turn on, the printer

  1. Plug in the power cord to the printer (Green arrow)
  2. plug the power into the wall outlet (Red Arrow)
  3. turn the printers power switch ON (Yellow arrow)

Set voltage on pus’s

Instructions:

  1. Press the led display toggle button to show the output voltage on both the top and bottom PSU, as you turn the adjustment screws the voltage number of the respective LED display will change, turning the screw clockwise will increase the number, turning the screw counter-clockwise will decrease the number.
  2. Using a small flat bladed screw driver,
  3. Adjust the brass screw top psu to 6V for the Servos
  4. Adjust the brass screw on the bottom psu to 12V for the arduino controller

Turn off and unplug the printer

  1. Turn the power switch of the printer to the OFF position (yellow arrow)
  2. Unplug the power cable from the printer (Green arrow)
  3. Unplug the power cable from the wall (Red arrow)

Connect psu 1 output to green barrel plug and screw to output of psu 1

  1. Locate another short wire that has both ends stripped (Blue arrow)
  2. Locate the barrel jack with the screw terminal end (Orange arrow)
  3. Remove the plastic from the stripped end of the wire
  4. Connect the wire stripped end to the barrel jack screw terminals, Red wire to the positive(+) and the Black wire to the negative(-) terminal as marked on the barrel jack housing.
  5. Tighten the screw
  6. Connect the other end of the wire to the output screw terminals of the lower PSU, Red wire connected to the “OUT+” positive side, and Black wire connected to the “OUT-” negative side.
  7. Tighten the screw

Connect power wire to top psu output

  1. Locate another short wire with both ends stripped
  2. remove the plastic from one end
  3. Insert the bare stripped wires into the screw terminal of the top PSU, Red wire to the “OUT+” positive port, and Black wire to the “OUT-” negative port.
  4. Tighten both screws

Connect servo shield to Arduino

  1. In this step you are going to attach the “Servo Shield” to the Arduino. The Servo Shield is what allows the Arduino to control all the servos that the Swapper3D uses to QuickSwap nozzles and it’s where the servos will be plugged into.
  2. Connect the Servo Shield to the Arduino board.
  3. Double check that all the pins are connected to their correct connectors along the top and bottom row.

Plug power into arduino

Instructions:

  1. Plug the Barrel connector into the receptacle on the Arduino board.
  2. Press it in firmly as far as it can go

Connect power to servo shield

Instructions:

  1. Remove the plastic pieces from the end of the short wire connected to the top PSU output screw terminal
  2. Connect the stripped ends of the wire to the screw terminals of correct polarity, Red wire to the “V+” positive terminal (Red arrow), and Black wire to the “GND” negative terminal (Green arrow).
