It looks like you're trying to assemble and install a hotend upgrade for your 3D printer. Here are some key points from the instructions: **Printing Notes** * Use PETG, ABS, or other heat-resistant materials instead of PLA. * Adjust print settings for thin walls (0.6mm) to avoid warping or cooling issues. * Print resolution: 0.2mm * Infill: 100% **Assembly Instructions** 1. Lay down the top part on the aluminum arm. 2. Secure with ball-bearing screw, ensuring smooth rotation. 3. Add a washer between printed mounting points and roller-bearing for smooth rotation. 4. Press bottom part onto hotend metal tube. 5. Install backplate on stepper motor, securing with arm and spring-screw. 6. Install stepper motor with arm in place. 7. Adjust screw position to control filament pressure. **Troubleshooting** * If top part doesn't fit, adjust holes or try printing a new top part. * Use a drill to enlarge existing holes if necessary. * Add a flat washer between printed mounting points and roller-bearing for smooth rotation. Please let me know if you have any questions or need further clarification on any of these steps!
