Rat Rig toolhead plate

4x M3x6 Countersink Screw

Second linear rail carriage

Tighten the M3x6 Countersink Screws to secure the plate to the carriage.

Pay attention to the orientation of the metal plate, having the pointy side towards the front of the printer, chamfered holes up.

Avoid using a ball end hex key, as they are more prone to damaging the sensitive M3 countersink screw head.

After tightening the screws, it is essential to verify that the X carriage retains its free movement. Excessive tightening of the screws may lead to the binding of the carriage.
