11.9 Alignment Recheck
Note: Alignment is critical. Recheck carefully.
1.) Turn on the alignment tool and recheck alignments. The table alignment must be the same as
in 9.3.6 Level and Center the Table to the Gantry, on page 59. If re-leveling is required, repeat
this procedure. Using the bubble levels, make adjustments as required to maintain required
alignment.
2.) Once alignment has been verified, torque all mounting bolts.
Tighten the location #1 through #7 anchors and torque to:
- Gantry and GT1700V Table:
75 N-m (55 ft.-lb.) for 8-inch Anchor (P/N 2106573)
54 N-m (40 ft.-lb.) for 7-inch Anchor (P/N 5487992-2)
- Lite Table:
Initially torque at 50 N-m (37 t.-lb.), then loosen until approximately 5 N-m (3.7 ft.-lb.)
3.) Remove the laser tools.
4.) Reinstall all the removed table panels and hardware.
5.) Reinstall the gantry rear cover.
Note: If you cannot replace the lower table cover because the floor interferes, adjust all of the table and
gantry levelers by half-turn increments to raise the table/gantry until the lower table covers clear the
floor. Then return to the alignment sections to level the gantry, level the table, and tighten the
locking rings, respectively.
Bolt centering is important to
provide ± 3mm of adjustment
for electrical alignment.
Always use the drilling
centering tool when drilling all
bolt holes.
