1601 Effector Assembly - parts needed

Assembled V6 hot-end (Chapter 8)

Hot-end fan assembly for V6 (Chapter 8)

Z-probe assembly for V6 (Chapter 7)

M3 x 14 socket capscrews x 3 (not shown)

M3 x 16 socket capscrews x 2 (not shown)

Molex Microfit female housing - 10-way

PTFE Bowden tubing

1602 Fit V6 to 40mm fan

Insert the hot-end groove in the mating slot in the printed 40mm fan mount and push fully into place. Zip-tie all the wires together as shown.

1603 Fit Hot-end and Z-probe to effector

Fit 2 M3 x 16 capscrews through the probe-holder base and fit it to the effector at the back - closest to the Z-tower carrying the extruder.

Insert the top of the V6 into the recess in the effector from below, align the bolt holes and partially tighten the 2 capscrews through the Z-probe. Fit 3 M3 x 14 capscrews through the remaining mounting holes in the effector, and do up all 5 bolts firmly and evenly. Do not overtighten or you will strip the threads tapped in the plastic.

NOTE: If you find this step difficult then you may want to remove the spider from the carriage adaptors and refit it after the hot end and Z-probe are in place.

1604 Complete the hot-end wiring

Note:  Some of the pictures that follow show an 8-way Molex Microfit housing, but apply equally to a 10-way housing except where stated otherwise.

Identify the correct orientation of the Molex Microfit female crimp housing before inserting pre-crimped cable ends.

This is a view of the top and front. The top has a triangular bump for latching the mating plug.

The front has 8 (or 10) rectangular holes, some of them with fillets in one corner to prevent the plug being fitted upside down.

This is a view of the top and rear of the plug. The crimps are inserted into these holes, which do not have any corner fillets.

A close-up of the inside of the housing, taken from the back, shows small bumps hanging down inside the sockets.

The crimps pre-fitted to the hot-end, probe and fan cables must be inserted into the housing with the open side facing upwards as shown, so as to fit past the bumps. The latching tabs on the crimps are very small, delicate and easily damaged!

Insert the 2 red hot-end heating resistor/cartridge cables in the top 2 left-side sockets of the housing. Orient them as described above, push in firmly and you should feel a slight click as they latch in. Do not force them - if they won’t go in they may be wrongly oriented. Remove, check and try again. Once they latch in correctly they cannot be removed without a special tool.

Repeat for the 2 green thermistor cables next to them.

Turn the housing over and insert the 30mm V6 hot end cooling fan crimps  (NOT the 40mm print cooling fan crimps!) in the 2 right-hand positions with the red wire on the right. Remember to turn the crimp pins over as well!  

Insert the 2 black Z-probe microswitch crimps next to the fan wires, …...

… followed by the black wire of the 40mm print cooling fan in the left-side socket next to the Z-probe switch wires.

Turn the plug over again and insert the red 40mm fan wire in the right-hand position next to the green thermistor wires.

Zip-tie the cables together just above the effector to complete.

1609 Fit Bowden Tube

Cut the 1.0m long PTFE tubing in half. Trim one end of one of the 500mm lengths if necessary to ensure a clean square cut, and insert it into the V6 hot-end, pushing it all the way down as described in E3D’s V6 assembly instructions (Chapter 8). Insert the other end into the pushfit on the extruder.

Set the remaining 500mm length of PTFE tube aside for later use as a filament guide.
