Carriage Module for FLSUN Cube

thingiverse

This set of carriages is designed specifically for the FLSUN Cube, accommodating its three supplied extruders. Each carriage can be quickly swapped out with minimal effort by clipping it (and an optional bolt) onto a universal belt bracket. Two notable issues with the standard carriage are addressed: 1. The carriage limit switch is lowered by 2mm to achieve the correct height. 2. The hot end no longer crashes into the bed, as the new carriage can lift off the front bearings on impact. The universal belt bracket (or bridge) remains permanently attached to the belt and has the limit switch fixed to it; the bearings will be secured to the rods. A new carriage, equipped with its extruder(s), heater(s), and thermistor(s), is placed over the rear rod, allowing the rear bearings to slide into the carriage housing from either side. The carriage can then be rotated to fit onto the front bearings, where it will be securely held by the weight of the extruder. The bridge clips into position with the carriage and is firmly fixed using two M3 screws. Locating pegs or M3 screws are positioned to prevent the bearings from sliding out of the carriage. A strong elastic band is used to hold the carriage down onto the front bearings, starting at one locating peg, going diagonally under the bearing, through the centre gap, and then diagonally under the other bearing before finishing at the other locating peg.
