    • Connect the remaining two motor cables to the two z-axis motors.

    • Connect the other side to the control board.

    Edit

  12. Connect the X-Endstop to the control board.

    • Connect the X-Endstop to the control board.

    • This is the endstop cable from the tool carriage wiring loom.

    Edit

  13. Connect the Hotend heater to the control board.

    • Connect the Hotend heater to the control board.

    • The connector can actually be pulled out of the board to make connecting the cables easier.

    • You will need a small flat head screw driver for this step.

    Edit

  14. Connect the thermistor to the control board.

    • Connect the thermistor to the control board.

    Edit

  15. Connect the hotend cooling fan cable to the control board. This is the cable that you marked earlier in the direct drive stage of the assembly.

    • Connect the hotend cooling fan cable to the control board.

    • This is the cable that you marked earlier in the direct drive stage of the assembly.

    Edit

  16. Connect the part cooling fans to the positions show.

    • Connect the part cooling fans to the positions show.

    • A fan can be connected to either spot.

    Edit

  17. Connect the brown cable from the probe directly to a positive terminal on the power supply. Connect the black and blue cable from the probe to the control board in the position shown.

    • Connect the brown cable from the probe directly to a positive terminal on the power supply.

    • Connect the black and blue cable from the probe to the control board in the position shown.

    Edit

  18. Before beginning, make sure that you have earthed yourself (by touching a large metal object) to avoid the chances of static damage. Prepare the four TMC2209 stepper drivers by removing them from their packaging and securing onto them their heat sinks as shown in the first image. Make sure the heatsink is not touching any of the pins.
