How to Use the D80 C Rotary Axis for Engraving a Stainless Steel Tumbler?
The D80 C rotary axis is perfect for marking cylindrical items like tumblers, bottles, or industrial parts. Here’s a simplified guide to setting it up and engraving a stainless steel tumbler.
1. Installation
- Mount the Rotary Axis: Place the D80 C on the laser engraver’s work platform, align with 100x50mm mounting holes, and secure using M5/M6 screws.
- Connect the Axis: Plug the rotary axis cable into the control box. Ensure the machine is powered off during setup.
- Adjust the Chuck: Use the D80 chuck to secure the tumbler. Tighten gently to hold it firmly, ensuring smooth rotation.
2. Configure the Software (Using EzCad)
· Enable Rotary Mode: In EzCad, activate “Rotary Marking” in settings.
· Input Parameters: Diameter of marked product
· Calibrate: Run a test rotation in EzCad to ensure smooth and accurate alignment.
3. Engrave the tumbler
· Secure the tumbler horizontally in the rotary chuck.
· Load your design (e.g., a logo or text) into EzCad.
· Adjust the focus and run a test engrave on scrap to confirm the settings.
· Start engraving. The rotary axis will smoothly rotate the tumbler as the laser engraves the design.
With the D80 C rotary axis, you can easily achieve professional-grade results on cylindrical items, enhancing both precision and efficiency.
