Complete Guide:

This guide is long and tries to cover the basics but not every scenario possible. We highly suggest you read through this guide here to go over some tips, tricks and watchouts for operating a Roller Rotary on a Thunder Laser Nova, Odin or Bolt series laser.

Setup:

Please refer to the quick start video at the top of this article for the detailed process of setting up the rotary.

Basic Steps

1. Placing the rotary in the machine (Either on Honeycomb, hangers or tray)

      Lower the Honeycomb down\Support Rails for clearance

      Install Rotary to honeycomb, tray or support rails

      Plug the rotary into the port

2. Place the tumbler in the rotary. Adjust the width of the rotary to fit

3. Adjust the height of the tail wheels so that the rotary is even to the laser head at the desired focus distance for the lens you are using

Find and Set your Steps:

Default Steps\Roller Diameter

Use these as the starting point as you dial in the steps based off the shape of the object you are engraving

Rotary	Steps	Roller Diameter Inches (mm)
RotoBolt	4300	.94(24)
Low Roller	4400	1.73(44)
Junior	4400	2.32 (59)
RotoBoss	4400	2.32 (59)

Basic Method for Dialing in Steps:

This basic tape method can be used for general, 1 sided, engraves. If you desire to do dual sided or full wraps, you will need to perform additional steps to make sure you have the most accurate setup. Use the table above to set the default Steps\Roller diameter for the rotary you are using. There are other ways to find your steps, this is just a single example.

1. Use a piece of masking tape and a ruler to mark 3 dots on the tape at the 0,2 and 4" marks

2. Place the tape on the tumbler, wrapping it around as even as you can

3. Set up a 4inch by .5"  rectangle in Lightburn. Use a Middle Left User Origin.

4. Send the job to the machine

5. Set the tumbler into the rotary and manually focus so that the tumbler surface is even to the laser head across the engraving area

6. Set the Origin with the red dot on the 2" mark on the tape

7. Frame the Job from the controller. Watch how the laser Red dot cross the 0 and 4" marks

8. If the Red dot crosses inside the 0 and 4" marks, increase the Steps and repeat step 7. If the Red dot crosses outside the 0 and 4" marks, decrease the Steps and repeat step 7

9. Once the Red dot crosses over the 0 and 4" marks, your steps are set and your rotary is set up for a basic 1 side engrave
