Setup
1. Initial Assembly and Connection

2. Software Configuration (LightBurn)
Proper software configuration is crucial for accurate engraving. Follow these steps in LightBurn:
- Go to 'Laser Tools' -> 'Rotary Setup'.
- Select 'Chuck' or 'Roller' mode based on your setup.
- Enable 'Enable Rotary' and 'Mirror Output to Rotary'.
- Measure the object's diameter and circumference using the provided calipers and tape measure.
- Input the 'Object Diameter' and 'Circumference' into the Rotary Setup.
- Adjust 'Rotary Axis' (mm per rotation) as needed. For chuck mode, a common value is 128.00 mm per rotation. For roller mode, a common value is 32.00 mm per rotation.
- In 'Machine Settings', navigate to 'Outputs setup'.
- Toggle 'Y Direction pin invert ($3)' to 'True' or 'False' as required for correct rotation direction.
- Save and write the new settings to your controller.
Refer to Video 1 for a visual guide on LightBurn settings for both Chuck and Roller modes.
Operating Instructions
1. Using Chuck Mode
Chuck mode is ideal for holding mugs, spherical objects like baseballs, and other items that can be securely gripped by the jaws.
- Select the appropriate jaws (L-shaped, hexagonal, or ladder) for your object and attach them to the chuck.
- Secure the object firmly in the chuck. For longer items, use the tailstock for additional support.
- Adjust the laser height to focus on the object's surface.

2. Using Roller Mode
Roller mode is suitable for cylindrical objects like pens, small bottles, or other items that can roll smoothly on the rollers.
- Remove the chuck jaws and install the roller attachment.
- Place the cylindrical object on the rollers.
- Adjust the laser height to focus on the object's surface.

3. Adjusting Angle for Tapered Objects
The R1 Pro features a 180° adjustable angle, allowing you to engrave on tapered objects like wine glasses or conical tumblers. Use the built-in angle adjustment mechanism and the spirit level to ensure the object's surface is parallel to the laser's focal plane.

Maintenance
To ensure the longevity and optimal performance of your ATOMSTACK MAKER R1 Pro, follow these maintenance guidelines:
- Cleaning: Regularly clean the rollers, chuck jaws, and main unit to prevent dust and debris buildup. Use a soft, dry cloth.
- Lubrication: Periodically check moving parts for smooth operation. Apply a small amount of light machine oil if necessary, avoiding contact with rubber rollers.
- Storage: When not in use, store the rotary module in a clean, dry place, preferably in its original packaging or a protective case.
- Inspection: Before each use, inspect all components for any signs of wear, damage, or loose connections. Tighten any loose screws.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Rotary not moving or incorrect direction | Incorrect cable connection; incorrect software settings (Y-axis invert, rotary enabled). | Ensure correct cable is used and securely connected. Verify 'Y Direction pin invert' in LightBurn Machine Settings is correctly set (True/False). Confirm 'Enable Rotary' is checked. |
| Engraving is distorted or stretched | Incorrect 'mm per rotation' or object dimensions in software. | Accurately measure object diameter and circumference. Adjust 'Rotary Axis' (mm per rotation) in LightBurn Rotary Setup. |
| Object not held securely by chuck | Wrong jaw type; jaws not tightened sufficiently; object shape incompatible. | Use the most suitable jaw type for the object. Ensure jaws are tightened firmly. Consider alternative holding methods for highly irregular shapes. |
| Laser focus issues on curved surfaces | Incorrect laser height; object not level (for tapered items). | Adjust laser height to ensure proper focus. For tapered objects, use the 180° angle adjustment and spirit level to make the engraving surface parallel to the laser. |
