Hello! I'm excited to showcase the Z axis upgrade for my Velleman K8200. Initial testing has yielded impressive results, with significant improvements in stability and print precision when utilizing the "Printer settings / Retraction / Lift Z" option. A photo of a dragon print serves as an excellent example, showcasing the before (printer parts) and after (dragon) states. I'll be uploading a video soon to provide a more detailed look at this upgrade. Here are the components used in this project: * 2 x NEMA17 motors with integrated Leadscrews, available in 300mm or 350mm lengths (Z max: 200mm or up to 240-250mm) * 2 x T8 Anti-backlash Spring Loaded Nuts * 4 x Linear Rods, 8mm diameter, and 300mm or 350mm length (Z max: 200mm or up to 240-250mm) * 8 x LM8UU Linear Bearings or Solid Plastic LM8UU Linear Bearings * 1 x Mechanical Endstop Switch with Cable * 2 x Ball Bearings, 8mm x 22mm x 7mm Recommended components: * M3 M4 M5 Screws and Nuts Set, Assortment Kit (mainly used 8-10 mm long) Printed Components: All elements were designed with a 0.2mm offset. * 1 x Arm_component_end_stop.stl * 1 x Arm_component.stl * 2 x Bearing_mount.stl * 2 x K8200_horizontal_mount.stl * 2 x K8200_vertical_mount.stl * 1 x Nema_17_Z_end_stop_mount_v1.1.stl * 1 x Nema_17_Z_mount_v1.1.stl * 1 x NEMA_17_Z_Top.stl * 1 x Z_knob.stl * 8 x Linear_rail_mount.stl For more information about this project, visit: https://forum.vellemanprojects.eu/t/k8200-2-color-z-axis-m2560-prot-mod/33173
