Building a Large Format 3D Printer - Part 2: Motion

Explore the second part of a comprehensive tutorial on building a large format 3D printer, focusing on the motion system. Learn about constructing a robust linear motion platform capable of moving an 18-pound pellet extruder within a massive 4'x4'x4' build volume. Discover the process of assembling and modifying OpenBuilds C-beam linear actuators for high-temperature operation, implementing a quad gantry leveling system, and integrating the motion components into the printer frame. Gain insights into critical speed calculations, carriage and actuator assembly, X-Y joint machining, wiring, and plasma cutting panels. Conclude with a sneak peek at the bed heater and witness the testing of the completed linear motion system.
