1. What can I do with the Rotary?

The Mr Beam Rotary is designed to precisely engrave round objects around their entire circumference. Objects with a minimum diameter of 10 mm up to a maximum diameter of 100 mm can be processed using this feature.


Note: The Rotary can only be used in conjunction with a built-in Mr Beam Height Extension and after updating to BeamOS 2. Also make sure you have the latest version of Beam OS 2.


Using the included object fixations, you can not only prevent your objects from slipping during the laser process but also utilize them for aligning different diameters.

3. Scope of delivery Rotary

We deliver your Rotary in assembled condition. However, there are of course some accessories that are also included:

  • Mr Beam Rotary
  • 2x gear racks
  • Inclined laser head mount with focussing plate
  • Screwdriver for adjusting the rollers
  • Xx object fixations (different types)
  • BeamOS 2.0 migration stick

4. How to install the Rotary

4.1 Prepare Mr Beam

  • Shut down the device, turn the key to the off position, and unplug the power cable.
  • Ensure that the Height Extension is installed in the Mr Beam. If not, install it according to the instructions in the Height Extension user manual.

4.2 Install gear racks


Note: Perform this section only during the initial installation. Afterward, keep the gear racks installed inside the Mr Beam housing, even when you are not using the Rotary.


  • Ensure that the X-axis is positioned all the way to the back, and the laser head is approximately in the middle of the working area.
  • Place the two provided gear racks, each with four indentations on the underside, onto the screw elevations in the Mr Beam housing.

4.3 Replace laser head mount

  • Move the laser head to approximately the center along the X-axis and about 5 cm forward in the Y-direction.
  • Disconnect the ribbon cable from the laser head and remove the dreamcut tube from the brass tube (only in the model 'dreamcut' and newer).
  • Unscrew the laser head from the standard laser head mount.
  • Press the carriage on the X-axis of the Mr Beam lightly together at the top and bottom to remove the standard laser head mount.
  • Press the carriage on the X-axis of the Mr Beam lightly together at the top and bottom to attach the angled laser head mount.

  • Secure the focusing plate for coarse focusing by pressing it onto the designated screw heads with the indentations.

  • Attach the ribbon cable and the dreamcut tube to the laser head.

  • Screw the laser head into the focusing plate at the desired height.


4.4 Insert Rotary

  • Open the two clips of the Rotary.
  • Install the Rotary by first placing the left gears onto the left gear rack. Then place the right gears parallel to them on the right gear rack.
  • Ensure that the Rotary is straight in the housing by sliding it with the two stops against the X-axis of the Mr Beam.


Note: If that's not the case, you'll need to lift the Rotary slightly to move it forward or backward to align the required teeth.


  • Close the clips on both sides, ensuring that only the upper timing belt is clamped.


Caution: Be cautious while closing the clips to avoid trapping your hand or a third party's hand.


  • Reconnect the Mr Beam, turn it on, and switch to the Rotary mode in the software.
Note: Usually, the camera of your Mr Beam automatically detects the Rotary. Otherwise, you can always manually switch to Rotary Mode using the small switch button.


  • Home the laser head. In the Rotary mode, after reaching the home position, the Laserhead will move a bit forward to provide you with a preview of the workpiece.
