Explore the process of upgrading a large format 3D printer with custom rack and pinion linear actuators to achieve 3X speed and reliability. Learn about designing and machining custom carriages, integrating rack and pinion systems for X and Y axes, and implementing ball screw actuators for the Z axis. Gain insights into the components and optimization of rack and pinion setups for peak performance in 3D printing. Discover the steps involved in relocating the printer, upgrading the gantry, tensioning the rack and pinion system, mounting gear racks, testing the new setup, and assembling the actuators. Understand the concept of a floating printhead and the process of machining carriage plates to accommodate the upgrades.
