This is a detailed guide for assembling a custom 3D printer. It includes instructions for installing brass knurl nuts, hotend, and fans, as well as wiring the printer. The guide also warns about the potential pitfalls of wiring and provides tips on how to avoid them. Additionally, it outlines the necessary materials and tools required for the assembly. Here's a summary of the key points: 1. Install Brass Knurl Nuts: * Press M2 brass knurl nuts into printed parts for fan holes. * Use M3 brass knurl nuts for attaching to aluminum effector. 2. Hotend Installation: * Ensure correct installation of nozzle in heatblock (refer to Thomas Sanladerer's guide). * Align hotend so nozzle is closer to the side with standoffs for 40mm fan. 3. Fan Installation: * Install larger fan outside assembly, facing downward. * Use M2 screws to attach to face. 4. Wiring Warning: * Take time and do it right; crimps must be correct to avoid wire issues. * Use a pin removal tool for connectors (or the SN-28B Dupont Crimper as an alternative). 5. Wiring: * Run wires together on corner of small and large fan, then zip tie them. * Leave excess wire, strip back, crimp only two sets of flaps, and insert pins into connector. The guide also includes a to-do list: 1. Add bed leveling attachments. 2. Make a video detailing assembly (especially pin crimps). Lastly, there is a change log that notes updates to the guide, including adding an assembly video on YouTube and updating links to sellers.
