Below is the schematic provided by East 3D in their manual. I’ve included a picture below, though you can also find this in your printed manual or in the PDF.

Wiring Schematic

Step 1 - Optional

Install Fork Terminals on Heatbed Wires

  • If you have the heat bed option, and if you have fork terminals, they aren't included in the kit, install them now.
  • Fork terminals ensure a good connection between the stranded wire and the terminal block.
  • Each of the two red wires from the heat bed get a fork terminal.

Step 2

Install the heat bed wiring

  • Route the head bed wiring over the edge of the base panel into the vicinity of the heat bed controller.
  • Add stickies and zip ties along the wire route and thread the red and black wires through the zip tie loops.
  • The small, black, thermistor cable is routed under the heat bed controller and over to the main controller. Plug the sensor into the terminal at the bottom of the board labeled B-Sensor.
  • The two red wires attach to the larger terminal block on the heat bed controller board. If you do not use fork terminals, be sure that all strands of the wire are fully captured by the terminal blocks. If a single strand is left expose, you risk shorting the terminals together.

Step 3

Route and Instal AC Cabling

  • I recommend routing the AC cabling away from all the DC cabling. This means the AC cable will run along the back panel and then along the base plate edge to the power supply.
  • Use stickies and zip ties to capture the cables while routing them.
  • The plug end should already be terminated.
  • At the power supply you will need to attach the red conductor to Line (L), the grey conductor to Neutral (N) and the yellow conductor to Ground/Earth.

At this point you have wired up all the items that can be wired up in the bottom of the machine. The next set of steps is for wiring up the components on the lifting platform to the controler on the base plate. Before you do that though, take some time to tidy up and tighten any zip ties that are still tight. If a cable is floppy, add another sticky and zip tie.

Step 4

Install Extruder Stepper Motor Cable

  • Once again, located the remaining stepper motor cables. There should be three of them.
  • A single cable is needed to go from the Extruder stepper motor to the control board. Remember that only one end of the cable will fit the stepper motor connector.
  • Unravel all other cables associated with the extruder, hot end, part cooling and limit switch. You may have more cables than pictured here, if you have a part cooler installed or an automatic bed leveler.
  • Figure out how all the cables will route around the extruder so that you don't pinch or pull cables too tight. Once that is done add a single zip tie to keep the bundle together.

Step 5

Add Wire Wrap and Stiffner

  • Remember that long, thick zip tie element from A Level Foam? This is the step where I think it should be used, I believe it is a stiffner for the wire bundle as it goes from the movable extruder to a fixed point on the lifting platform.
  • With the long zip tie held against the cable bundle, wrap the whole bundle of cables + zip tie in the wire wrap.
  • Once completed drape the wire wrap so that there is enough vailable for the extruder to move freely over its whole range of movement. Then fix the end of the wire wrap to the lifting platform. See the pictures.

Step 6

Route Extruder Cables and plug in Extruder Stepper Motor

  • Move the lifting platform to its upper most position. This is so that we leave enough cable slack as to not restrict the lifting platform movement.
  • Add a sticky and zip tie to the base plate to hold all the cables in place.
  • Route the extruder stepper motor cable to the control board and plug it into the connector labeled E Motor.

Step 7 - Optional

Add Ferrules to the Hot End Heater Wires

  • I choose to add ferrules to the hot end heater cartrigde.
  • Pick out the appropriate size ferrule and use a crimper to securely attach the ferrule to the wire.

Step 8

Attach all cables from Extruder

  • The black limit switch cable should be plugged into the first connector from the left, for the row of connectors just below the stepper motor drivers.
  • The hot end thermistor cable, white with white connector, should be plugged into the connector labeled H-sensor at the bottom right of the board.
  • Attach the hot end heater cartridge to the green terminal block on the right edge of the board. The port is labeled HeatHead.
  • Attach the hot end cooling fan to the connector labeled Fan2 on the right edge. The fan cable is red and black with a white connector. Be sure to insert the connector in the proper direction.

Step 9

Route and Attach Remainig Cables

  • Plug in the remaining stepper cables to the X and Y axis stepper motors.
  • Attach the hot end heater cartridge to the green terminal block on the right edge of the board. The port is labeled HeatHead.
  • Plug the X Axis stepper motor cable to the stepper driver connector labeled X Motor.
  • Plug the Y Axis stepper motor cable to the stepper driver connector labeled Y Motor.
  • Plug the limit switch into the second connector from the left, second row below the stepper driver.
  • If you have all three limit switch plugged into the same row, you have done it wrong. Two should be in the row of connectors closest to the stepper drivers and one in the row of connectors below that.

Step 10

Final cable clean up

  • Add stickys and zip ties to the base plate for capturing the remaining cables that are floppy.
