Maintenance
7.6 Drive units
7.6.1 Belts
All axes are driven by toothed belts and are
therefore maintenance-free.
The toothed belts must be checked for tears
and damage each week in order to avoid any
breakages.
7.6.1.1 Belt tension - X, Y, Z axes
X-axis
Y-axis
Z-axis
The toothed belt runs between the fixed plate
above the deflection pulley, drive roller and
clamping plate.
To change the belt tension it is necessary to
slacken off the 4 clamping bolts (Pos.1) and
adjust the tensioning nut (Pos.2). This does not
alter the toothed belt clamp.
Retighten the clamping bolts after adjusting the
belt tension.
The drive wheel must be allowed to move in
order to tension the lower end of the belt. It
is therefore necessary to release the motor
brake.
