1.5.1 Removing the Z-Axis Motor

Procedure:

1. Turn OFF the machine power.

2. Disconnect the two (2) electrical connections to the motor (at front of the

XY-table).

3. Retract both the IN and OUT carriers, and widen the machine’s conveyor

rails to allow better access to the machine.

4. Move the XY-table to the out loading position.

5. Manually raise the table using the Z-axis timing belt on the left hand side

of the table.

Note: It is possible that timing belt slippage may occur when adjusting the table height using

the timing belt at the right hand s ide o f the table..

6. Loosen the belt tension by loosening the two (2) allen bolts on the right

hand side of the table, and then lower the tension using the adjustment

bolt as shown below.

8. Pop the span-ring by removing the four (4) allen bolts and screwing two

of them into the adjacent holes until loose. Remove the span-ring.

9. Remove the motor gear followed by the four (4) mounting bolts securing

the motor bracket to the XY-table.

1.5.2 Installing the Z-Axis Motor

1. Secure a new motor to the machine.

2. Reconnect the two (2) electrical connectors to the motor.

3. Replace the motor and fasten in place with the four (4) mounting bolts.

4. Replace the table top and secure using the lock nut jig.

1.5.3 Adjusting the Table Top Parallelism

There may be occasions where it is necessary to adjust the parallelism of the table top.

An excessively uneven table top will result in damaged nozzles in some areas and

tombstoning of parts in others.

Procedure:

1. Push the adjustable rail towards the back of the table, while ensuring to

leave the lock nuts exposed.

2. Inch the table in the X and Y-directions towards their respective minus

side mechanical stoppers, while taking care not to enter overtravel.

3. Attach a dial gauge to the Fiducial camera bracket and attach the needle

to point A (refer to diagram below).

4. Using A as the reference point, set the dial gauge to zero and inch in the

Y-direction to take the needle to point B.
