2.3.5 X-axis assembly

• Material preparation

• First, solder the connecting wire at one end of the light strip (refer to the wiring diagram for wiring);Insert the light strip into the profile and stick it in the center；
• Install 1 Pcs linear guide MGN12H (length 765mm) on the side of the profile，Use M3x8 FHCS for fixing；
• Install the left/right XY joints on both sides of the profile and tighten the screws (make sure the light bar is on the bottom).

2.3.6 Y-axis assembly

• Material preparation

-First install the AB motors onto the profile (two profiles of the same length are Y)；

• Insert the screwed guide rail from one end of the profile (MGN9H length 760mm，2PCS)，Use M3x8 FHCS for fixing，locking screw；
• Finally install the AB idler assembly；Tighten all parts screws.

X-axis installation

• Install the previously assembled X-axis assembly onto the Y-axis assembly using the SHCS M3x6mm；
• Tighten all parts screws.

2.3.7 XY Belt, IDM bracket installation

XY Belt

• Install the belt as shown；

IDM bracket installation

• After the belt is put on, use Cartographer CNC toolhead to fix it, and use M3x6 BHCS to tighten the belt；Use M3x8 FHCS to fix the IDM ScannerCNC metal parts on the guide rail slide；
• Use M2x10 FHCS to fix 1 Pcs of micro switches on the printed part and 1 Pcs on the metal part；Install the micro switch print on the IDM ScannerCNC metal part and fix it with M3x8 FHCS；

Z-axis connector

• Material preparation

• First install the GE5C fisheye bearing in the connector slot and tighten the screws；
• Use SHCS M5x22 screws to pass through the spring and spacer and lock it to the frame.

• Tilt the gantry into the frame，Use SHCS M3x8 screws to fix the gantry to the guide rails；

2.3.8 Z-axis Belt

• Pass the belt through the reduction motor and idler pulley as shown, and then fix it to the gantry assembly；
• Tighten all parts screws.
