Oldham Coupler for 3D Printers: VzBoT BLV Correction

The Oldham Coupler is an essential component for achieving smooth, precise movement in 3D printers, particularly the VzBoT models. Designed to handle the demands of high-speed operations, our Oldham Coupler is engineered to provide excellent performance and reliability, making it the ideal choice for both beginners and professional users alike.

What is an Oldham Coupler?

An Oldham Coupler is a type of mechanical coupling that connects two shafts while allowing for slight misalignment between them. This is crucial in 3D printers where precision is vital for quality prints. By using a central disc with grooves that fit into two outer hubs, the Oldham Coupler provides a robust connection. Its unique design helps to isolate vibrations, ensuring that extruder movements remain smooth and controlled.

Features & Benefits

• High Tolerance Levels: Our Oldham Coupler is constructed with high-quality materials, ensuring it can withstand the mechanical stresses of continuous use. This means improved longevity and durability for your printer.
• Precision Alignment: By allowing for minor misalignments, this coupler guarantees that your printer's axles remain aligned for optimal performance, thus enhancing print accuracy.
• Reduced Wear and Tear: The design minimizes friction and wear, resulting in a decrease in maintenance needs and operational downtimes, saving time and money in the long run.
• Easy to Install: The Oldham Coupler is designed for easy installation, allowing users of all skill levels to replace or upgrade their existing couplers quickly.
• Compatible with Various Models: Specifically designed for VzBoT BLV 3D printers, it can also be fitted to a range of other models, making it a versatile choice.

Perfect for Z-axis Applications

The Oldham Coupler is particularly beneficial for Z-axis applications in 3D printers. When used in conjunction with a lead screw and a hotbed, the coupling ensures smooth upward and downward motion, which is fundamental for the layering process in 3D printing. This eliminates issues such as layer misalignment and z-banding, resulting in high-quality prints that meet your expectations.

Installation Guide

Installation of the Oldham Coupler is straightforward, even for novice users. Here is a simple guide to help you:

1. Gather Your Tools: You will need a wrench, screwdrivers, and possibly a replacement belt if adjustments are necessary.
2. Turn Off and Unplug Your 3D Printer: Safety first! Make sure your printer is completely powered down before starting.
3. Remove Existing Coupling: Carefully detach the existing coupler from your printer's Z-axis by loosening the screws with a screwdriver.
4. Install the Oldham Coupler: Position the new Oldham Coupler onto the Z-axis screw and secure it firmly using the provided screws.
5. Check Alignment: Ensure the coupler is properly aligned and that any shafts are level.
6. Power On Your Printer: After confirming everything is secure, plug in your printer and perform a test print to confirm proper installation.
