The version history shows several updates and improvements to a DIY printer design, referred to as Version 1.0 to Version 1.5. **Initial Problems:** - The initial model (Version 1.0) has significant problems including: - Z-axis wobble - Binding issues with the linear bearings - Rigidity issues due to weak corner joints - Extruder grip inconsistencies leading to unpredictable extrusion - Untidy wiring **Subsequent Improvements:** - Version 1.1 fixes several of these initial problems, including introducing a more solid hotend mount and incorporating an E3D-Lite6 Hotend. - Later updates (Version 1.2) continue to improve the design with better rigidity through larger corner brackets and cross braces, adding endstops for automatic bed leveling, improving extruder setup with bowden and integrating it with fan cooling, among others. - Each subsequent version refines the printer’s performance, focusing on reliability, stability, print quality, and simplifying assembly. Key changes include using a more robust extruder carriage, strengthening several components, and reducing clearances to improve build area without compromising mechanical integrity. **Final Upgrades (Versions 1.3 - 1.5):** - Version 1.3 further enhances structural strength and print precision by reinforcing several critical areas. - The updates continue with the release of Version 1.4, which incorporates specific adjustments for easier assembly, improved printer compactness, reduced chance of breakage in corners or under movement stress, and better overall print quality thanks to smoother Z-axis performance using LM8LUU linear bearings. The culmination of these changes results in a refined and capable printer design as evidenced by Version 1.5. This final iteration improves upon its predecessors by ensuring even more stable Z axis functionality, enhanced bed leveling precision (utilizing three points for greater control), increased durability, and practical usability. It’s notable for adopting specific mounting enhancements to hotend carriages for enhanced air circulation, improved cooling of the print zone and integrated 3-point leveling on the PCB heatbed. Each version in this update series highlights continuous effort to improve the design from initial shortcomings to address both functional reliability and user experience, making Version 1.5 an appealing and well-rounded entry-level printer or DIY build project for those familiar with mechanical assembly or those willing to invest time learning.
