Fitting the Z Head

< Previous | List | Next >

You will need 

  • Z Head

Installing the Z Head

Positioning the Z Head

Set up the position for the Z Head prior to mounting it.

The Z Head assembly has to be inserted from the far end of the Upper X Beam, with the extraction elbow facing towards you (pointing away from the Y Bench).

A: Extraction elbow

Do not try to insert the Z Head from the home end of the Upper X Beam.

Align the Z Head wheels and pinions with the Upper X Beam channels

Prior to inserting the Z Head, you will need to align the wheels and pinions of the Z Head with their corresponding channels. 

B: Z Head wheels 

C: Pinions

The Upper X Beam channels for the Z Head wheels and pinions are shown below.

D: Pinion channels

E: Wheel channels

Use the motors on the sides of the Z Head to hold, lift or position the Z Head along the beam.

F: Z Head motors

Position the Z Head on the Upper X Beam as shown:

Take care to align the wheels with the inner channels, and the pinions with the outer channels.

G: Pinion

H: Wheel

G1: Pinion channel

H1: Wheel channel

The wheels (H) and the pinions (G) should fit to their respective channels for correct fitting like this:

Loading the Z Head into the Upper X Beam channels

Load the Z Head by inserting the wheels into the Upper X Beam channels until the Z Head holds onto the beam. 

Load the Z Head partially into the channel, or leave the bottom Z Head tab sticking out of the channel. This is to prepare for the drag chain latch plates to be fitted.

I: Bottom Z Head tab

Connecting the signal cable and latch plate

Connecting left hand side latch plate

Pull the signal cable through the recess channel.

J: Recess channel

K: Signal cable

And rest the signal cable on the recess channel like this:

Place the drag chain latch plate over the rectangular face on the left hand side of the Z Head bottom plate.

L: Latch plate

M: Z Head bottom plate 

Ensure the signal cable sits in the recess channel on the left of the latch plate, as shown below.

K: Signal cable

J: Recess channel

L: Latch plate

Ensure the latch plate sits on the tab of the bottom Z Head plate, and is not partially fit or misaligned as this can damage the wheel channel.

 

Successful fitment of the latch plate should look like this:

Incorrect fitting is where the latch plate does not properly sit on the tab of the bottom Z Head plate.

Secure the latch plates on the bottom Z plate with a thumbscrew.

N: Thumbscrew

Connecting signal cable

The signal socket located on the left hand side of the Z Head connects to the signal cable.

O: Signal cable

P: Signal socket

The Z Head signal cable has a thumbscrew on the top. Plug the signal cable to the socket, and secure it with the thumbscrew.

Q: Signal cable thumbscrew

The signal cable connection should look like this:

Connecting the power cable and latch plate

Connecting right hand side latch plate

The power cable is located on the right hand side of the Z Head. Pull the power cable through the recess channel.

R: Power cable

S: Recess channel

Rest the signal cable on the recess channel like this:

Place the drag chain latch plate over the protruding face on the right hand side of the Z Head.

T: Z Head bottom plate 

U: Latch plate

Ensure the signal cable sits in the recess channel on the left of the latch plate, as shown below.

R: Signal cable

S: Recess channel

U: Latch plate

Ensure the latch plate sits on the tab of the bottom Z Head plate, and is not partially fit or misaligned as this can damage the wheel channel.

 

Successful fitment of the latch plate should look like this:

Incorrect fitting is where the latch plate does not properly sit on the tab of the bottom Z Head plate.

Secure the latch plate in place with a thumbscrew.

V: Thumbscrew

Connecting the power cable

The power socket located on the right hand side of the Z Head connects to the power cable.

W: Power cable

X: Power socket

The Z Head power cable has a thumbscrew on the top. Plug the power cable into the socket, and secure it with the thumbscrew.

Y: Thumbscrew

The power cable connection should look like this:

Connecting the spindle

If your SmartBench already comes with a spindle pre-installed in the Z Head, then read through to learn about how to connect the spindle cables to the Z Head.

If the spindle is not already installed, click here to learn how to load the spindle into the Z Head.

The spindle has two cables which connect to the Z Head.

Z1: Z Head spindle-power socket.

Z2: Spindle power cable.

Z3: Spindle signal cable.

Z4: Z Head spindle-signal socket.

Plug the spindle power cable (Z2) into the Z Head spindle-power socket (Z1).

Plug the spindle signal cable (Z3) into the Z Head spindle-signal socket (Z4). 

Fully engage the Z Head

Check that both latch plates and all cable connections are properly mounted and secure.

 

When you are ready, push the Z Head onto the Upper X Beam until all wheels are engaged.
