➠ Carefully insert the X-axis motor unit (item 4 in Fig. 7.5 - 7) as far as the stop, making sure that
you do not damage the toothed belt. The motor cable points towards the permanent magnets
of the linear drive.
➠ Use the two hexagon socket-head screws (item 7 in Fig. 7.5 - 7) to clamp the X-axis motor unit.
➠ Fit the cable holder for the trailing cable (item 10 in Fig. 7.5 - 7).
➠ Fit the board holder (item 9 in Fig. 7.5 - 7).
➠ Fit the X/Y distributor (item 5 in Fig. 7.5 - 7).
➠ Plug in all plugs into their socket on the X/Y distributor (item 5 in Fig. 7.5 - 7).
➠ Use the cable clamp (item 11 in Fig. 7.5 - 7) to fix the flat ribbon cable.
➠ Use cable ties to fix all cables.
CAUTION
Make sure that the cables are firmly seated. Otherwise, the high acceleration forces may
cause the cable to slip out of position and shear through.
➠ Turn the hexagon socket-head screw (item 2 in Fig. 7.5 - 7) to pre-tension the X-axis toothed
belt.
➠ Use the three M6 x 8 hexagon socket-head screws to fit the black cover strip to the cross-beam
above the gantry concerned.
➠ Connect the cable of the fan motor to the socket.
