Dismounting steps are discribed as follows.
A. The horizontal stepping motor is fixed to the motor support with four M3X12 hexagon
socket head screws allocated with plain pad and spring pad. First, remove the
horizontal stepping motor by loosening the four screws, and then take out the horizontal
synchronous belt, and then remove the horizontal synchronous belt wheel which is
fixed to horizontal stepping motor by loosening two M3x5 hexagon socket head set
screws.
B. The vertical stepping motor is fixed to the bracket with three M4X16 hexagon socket
head screws allocated with plain pad and spring pad. First, remove the vertical stepping
motor by loosening the three screws, and then remove the vertical synchronous belt
wheel which is fixed to vertical stepping motor by loosening two M3x5 hexagon socket
head set screws.
C. Remove the dustproof cover by loosening four M3x6 cross pan head screws, and then
remove the press plate by loosening two M3x6 cross countersunk head screws, and
finally take out the vertical synchronous belt.
D. The horizontal senor is fixed to the motor support with one M3X6 hexagon socket head
screw. Remove horizontal sensor by loosening the screw. The vertical sensor is fixed to
the bracket using one M3X6 hexagon socket head screw. Remove vertical sensor by
loosening the screw.
E. The limited position plate which is fixed by three M3X6 cross pan head screws can
adjust horizontal position of the probe arm assembly.
