Settings

4-28: Replacing the X-axis motor unit

Gantry 2 or 4

X Carefully insert the X motor unit (4) as far as

the stop, making sure that you do not damage

the toothed belt. The motor cable points

towards the permanent magnets of the linear

drive.

X Fix the X motor unit into place with the two

hexagon socket-head screws (7).

X Fit the cable holders for the trailing cable (10).

X Fit the board holder (9).

X Plug the X motor plug into its socket on the X/

Y distributor (5).

X Fix the flat ribbon cable with the cable clamp

(11).

X Fix all the cables with cable ties.

CAUTION:

Make sure that the cables are firmly

seated. Otherwise, the high

acceleration forces may cause the

cable to slip out of position and shear

through.

X Tension the X toothed belt with the hexagon

socket-head screw (2).

X Use the three M6 x 8 hexagon socket-head

screws to fit the black cover strip to the

crossbeam above the gantry concerned.

X Connect the cable of the fan motor to the

socket.

4-29: Replacing the X-axis motor unit

X Push the head mount (1) towards the X axis

motor unit, as far as the stop on the

elastomeric spring.

X Turn the hexagon socket-head screw (2) to set

the belt tension to 53 Hz + 1/-3 Hz.

CAUTION:

Do not overstretch the toothed belt

when adjusting the belt tension.

X Secure the hexagon socket-head screw (2)

with the locknut (8).

Installation

X Insert the tubes into the new raceway but do

not yet tighten the grub screws which fasten

these tubes.

ATTENTION:

Take care not to bend the tubes.

X Fit the raceway onto the front of the head.

X Fit the raceway gauge onto the motor axis, as

shown in the diagram. Tighten the gauge with

the three screws (1) provided, so that you can

reach all the screws (2) for the raceway and

the Z axis.

X Fit the 0.01 mm feeler gauges (3) on both side

of the Z axis (or the Z axis mechanics gauge).

X Fasten the circular arc guide with the three

screws (2).

X Dismantle the gauge for the raceway.

X Remove the feeler gauges and test the Z axis

for ease of movement.

X With the help of the feeler gauge, adjust the

metal tubes for the air kiss supply to 0.7 mm

higher than the circular arc guide and fix into

place with the grub screws (Allen key,

0.71 mm).

X Attach the silicon hose to the metal tubes and

fix this to the housing with the hose holders.

X Fit the star back into the head. (See section

"Replacing the Star" in the Service Manual.)

Set the zero position with the power pack and

determine the zero point correction value.
