Service manual
The X carriage can run over the X guide. The body of the X carriage (1) supports the aluminium profile (2) that holds the
steel rails (3) on which the Y carriage runs. The photodetector (4) indicates the start position of the movement of the Y
carriage. The motor (12) operates the Y carriage belt by means of the pulley (11). The pulley (9), fitted on the bearing (10),
returns the belt operated by the motor. The barrier (5) obstructs the X start photodetector when the X carriage reaches its
start position. The X carriage runs on its guide using the linear slide unit (6) fastened to the carriage body. The belt (7)
operates the X carriage. It is held to the body of the X carriage by means of the fastening (8). The support (13) holds the
terminal of the X carriage chain (14). The Y carriage chain terminal (15) is screwed directly onto the X carriage. The rubber
protection (16) prevents the Y guide from injuring the user.
