Z-Axis Supports

thingiverse

The Z-axis supports and guide rod spacer is designed for a rigid Z-axis movement, with the top supports aiding in alignment by capturing lead screw tops and maintaining position relative to guide rods. However, users might find optimal performance when disengaged. Depending on prints, a set screw could help in capturing bearings as shown in an image. Mock bearings are for top brackets, assisting with alignment. Eugene suggests that a better lead screw Z-carriage mechanism/bracket is needed to allow screws to wiggle slightly without causing torque inconsistencies or affecting Z-height. PLA printing at 0.3 mm layer height requires support; however, aligning the Aluminatus T1 can be challenging. Users should loosen everything, including Z stepper motor screws, base gantry mounts, Z-axis supports, lead screw nuts, and X-gantry/guide rod brackets. The order of tightening is: gantry-to-base brackets, Z-axis supports (including top supports), adjusting X-gantry vertical elevation, lead screw nuts, one screw on each guide rod-to-X-gantry bracket, and finally, tightening all guide rod bracket screws. Top Z-axis supports should then be removed for optimal performance.
