Further, the acquisition of a new pellet extruder, with a volumetric flow rate five times greater than its predecessor, necessitated immediate upgrades to essential parts of my printing process, including the actuators for improved speed and reliability. In this video, I detail the process of designing and machining custom carriages to integrate rack and pinion linear motion systems for the X and Y axes (speed!) and ball screw actuators for the Z axis (reliable). I also discuss the workings of the rack and pinion system, its components, and share insights on optimizing this type of linear motion setup for peak performance Table of Contents: 00:00​ - Introduction 00:56​ - Relocating Printer 02:00​ - Print Speed 06:56 - Z-Axis Ball Screws 13:49 - Ball Screw Actuator Assembly 15:08 - Upgrading the Gantry 16:32 - Rack and Pinion (R&P) 17:09 - R&P Components 21:14 - R&P Tensioning 23:48 - Mounting Gear Racks 24:50 - R&P Testing 28:54 - R&P Actuators Assembly 37:46 - Floating Printhead 40:53 - Machining Carriage Plate #3DPrinting #LargeFormatPrinting #rackandpinion
