ARTILUME Mini Rotary Attachment User Manual

Welcome to the ARTILUME Mini Rotary Attachment manual. This guide provides step-by-step instructions for hardware setup, roller spacing adjustment, machine positioning, and software configuration across supported laser engraver models (T1, U1, and A4).

1. Package Contents & Specifications

Before assembly, verify that your package includes the following components:

Rotary Attachment Base: Equipped with 130 mm rubber rollers offering 2 adjustable spacing positions to support both cylindrical and tapered/conical objects (e.g., tumblers, mugs, and cups). Maximum load capacity: 1.5 kg (3.3 lbs).
Riser Legs: 25 mm diameter, maximum stackable height 80 mm (used to elevate the laser frame).
Connecting Cables (3 included):
- Cable A: Adapter cable for third-party motor compatibility.
- Cable B: For T1 and A4 models.
- Cable C: For U1 models.
Hex Wrench & Hardware: For roller spacing adjustment and assembly.

2. Adjusting Roller Spacing (Step 1)

Adjust the distance between rollers based on the diameter of your object:

Place your object between the rollers to check whether the spacing provides stable support without causing the object to sit too high.
If adjustment is needed, use the hex wrench to loosen and remove the screw on the adjustable rear support bracket.
Slide the adjustable roller to set the proper distance relative to the fixed roller, then tighten the locking screw.
Adjust the belt tension pulley assembly so the timing belt remains taut, then tighten the locking bolt.
Rotate one roller by hand to ensure the second roller and motor pulley turn smoothly together. If movement feels stiff, slightly reduce belt tension.

3. Machine Setup & Placement (Step 2)

Place the laser engraver on a flat, level surface and disconnect the Y-axis stepper motor cable.
Install 4 equal-height riser legs under the corners of the machine frame to elevate it. (Note: The T1 model is not compatible with riser legs and does not require them.)
Position the rotary attachment underneath the frame and connect the machine's Y-axis motor cable to the rotary motor.
Align the rotary attachment so the object's axis runs parallel to the X-axis, ensuring the laser beam hits perpendicular to the top center of the object.

Note: Select riser height based on the diameter and length of the object being engraved.

4. Model-Specific Setup & Focusing (Steps 3–5)

Follow the specific alignment and focusing steps for your laser model:

T1 Model Setup (Step 3)

Position the rotary attachment as shown in Figure 3, with the motor on the left side.
Place the focal positioning block as shown in Figure 4 to adjust the focus.
Once connected, no software parameter adjustments are required for the T1.

U1 Model Setup (Step 4)

Position the rotary attachment as shown in Figure 5, with the motor on the right side.
Place the focal positioning block as shown in Figure 6 to adjust the focus.

A4 Model Setup (Step 5)

Position the rotary attachment as shown in Figure 7, with the motor on the right side.
Place the focal positioning block as shown in Figure 8 to adjust the focus.

5. Installing Riser Legs (Step 6)

Riser leg installation varies by model:

A4 Model: Screw the riser legs into the four support feet, then secure them using the included lock nuts.
U1 Model: No nuts required. Screw the riser legs directly into the built-in threaded mounting holes on the feet.
T1 Model: Riser legs are not required.

6. Software Configuration Guide (Step 7)

Important Note: T1 model users do not need to change any software settings.

LightBurn Settings (U1 Model)

Open Rotary Setup in LightBurn.
Select Roller type and toggle on Enable Rotary.
Set Rotary Axis to Z Axis.
Set parameters: mm per rotation = 40.00, Roller Diameter = 12.700 mm.

LightBurn Settings (A4 Model)

Open Rotary Setup in LightBurn.
Select Roller type and toggle on Enable Rotary.
Set Rotary Axis to Y Axis.
Set parameters: mm per rotation = 40.00, Roller Diameter = 12.700 mm.

LaserGRBL Settings (A4 Model)

When using LaserGRBL, calculate the Y-axis step value ($101) using this formula:

4250 ÷ Object Diameter (mm) = Value

Type $101=[Value] into the console and press Enter.

Note: $101 configures the Y-axis steps per mm. After completing rotary engraving, enter $101=80 in the console to restore default factory settings.
