8.4.4 Calculate the Zero Point Correction for the D Axis
PLEASE NOTE
The starting value on the axis display should be approximately 0 if the pin of the nozzle support is pointing
towards component table no. 3.

Key to Fig. 8.4.1
To accurately calculate the zero point correction value, you require the IC head camera and a type 416 noz-
zle.
●
Place the nozzle in the correct position, as shown in Fig. 8.4.2.
●
To ensure that the nozzle is clearly visible to the IC camera, mark the tip of the nozzle with washable white
paint.

The axis display should read 0 digits. If this is not the case, proceed as described for calculation of the
zero point correction for the z axis (see section 8.3.9, page 8 - 14).
