5. Test for approximately 8mm of deflection on
top side of Z-axis belt at its center between
table leadscrews (see
Figure 78).
— If belt deflection is approximately 8mm, no
adjustment is required.
— If belt deflection is greater than or less
than 8mm, proceed to
Step 6.
7. Repeat Step 5 on opposite Z-axis synchro-
nous belt.
If a synchronous belt begins to slip or has frayed
after long-term use, the belt should be replaced.
The following section outlines procedures for
replacing the synchronous belts on the Model
G0911–G0914.

X-Axis Belt Replacement
1. DISCONNECT MACHINE FROM POWER!
2. Open top loading door and center laser head
assembly over table.
3. Remove (2) cap screws on right belt mount-
ing bracket securing X-axis synchronous
belt, then remove bracket from belt (see

6. To adjust belt tension, loosen (2) cap screws
on belt tensioner, adjust belt tensioner
towards or away from belt, then secure cap
screws (see
