Anet A8 Bed LM8LUU Bearings For Custom Carriage

thingiverse

Designed for the Gulfcoast Robotics Anet A8 A6 3D Printers Upgrade Y Carriage Anodized Aluminum Plate, this upgrade is engineered to utilize three LM8LUU bearings for the hotbed instead of the standard four LM8UU from Anet. This innovative approach enables easier bearing alignment and better stability. **Key Features** * Simplified bearing alignment * Enhanced stability * Lighter than stock bearing blocks * A slightly larger build volume due to a recessed endstop "wall" **Required Components** * 1x Custom Y Carriage - The custom placement of holes is essential for using the bearings in this manner.

I personally use Misumi branded ones to eliminate all play.

You can use the ones that came with your Anet A8. * 6x Zip Ties - For securing the bearings. **Printing Instructions** * No supports are required. * Print all parts exactly as oriented to maximize quality, strength, and ease of printing. * You may use 20% infill for all parts. * You may print all parts at 0.2mm layer height. **Assembly Instructions** 1. Print out the bearing blocks. 2. Snap the LM8LUU bearings into the blocks. 3. Secure the bearings with zip ties, which is not strictly necessary but may be helpful. 4. Pay attention to the file names to determine which bearing block goes where. It does matter. Also, check the second picture to see exactly how the bearings should be mounted in relation to the custom carriage's holes. * The left side bearing can be oriented in any way. * The right back bearing needs to have the endstop "wall" facing the endstop. * The right front bearing needs to have the text "FRONT" facing the front. 5. Tighten the M4x8 screws into the bearings. If you have any questions or encounter issues, be sure to comment! I will do my best to assist you. As usual, I am including the Blender source file in case you want to edit it.
