3.11 Check the alignment of the x, y and z encoder reader
Furthermore the alignment of the x, y and z readers need to be checked whenever the readers or
the scale bar has been changed.
Requirement:
● Machine is switched on.
Figure 3-32: Diagnostic page
1. Go to the diagnostic page.
2. Click on the tab "Unit function".
3. Go to the section "Gantry".
4. Select the X button and click on the "Home" button.

Figure 3-34: Y scale bar
1. Unscrew the screws (1) off the scale bar using an T shaped Allen key size 2.5.
2. Carefully pull out the scale bar.
3. Do not damage the encoder reader. The sensitive reader may be protected by using a piece of
paper.
4. Put in the new scale bar.
The surface of the scale bars
Fingerprints or scratches damage the scale bars which then need to be exchanged.
Do not touch or scratch the surface of the scale bars.
Installation
1. Tighten the screws (1).
2. Check the space between the reader and the scale bar by using the 2.1 mm spacer provided.
3. Check the lights of the encoder at the back of the machine.
4. Slowly move the gantry backwards and forwards. See section 3.9 Color code for the encoder
readers.
5. Adjust the brackets when the lights indicate to do so.
6. The steps to change the other scale bar are identical.
7. Check the alignment of the y scale bar. Go to section 3.10 Check the alignment of the encoder
reader of the Y gantry and section 3.11 Check the alignment of the x, y and z encoder reader.
