3.10 Check the alignment of the encoder reader of the Y gantry
Whenever the encoder readers have been removed, the readers need to be realigned.
Requirements:
● Machine is switched on.
● Optical head is centered on the X position.
Figure 3-29: Position of the flexures and the optical head
Key:
1) Optical head
2) Flexures
Key:
1) Flexures
Figure 3-30: Flexures
1. Install the flexures (1) at the gantry.
NOTICE
Flexures
Without the flexures the gantry can be moved in slightly different positions. The flexures
help to hold the gantry in the same position so that both sides are align to each other.
