Before we dive into design, software, or settings, your engraving starts with the proper mechanical setup. The ARC (Automatic Rotary Chuck) is essential for engraving on cylindrical objects like mugs, bottles, and tumblers. Here’s how to get it dialed in:
1.1 Place the ARC in the Engraving Area
Start by placing the ARC rotary accessory securely inside the working area of your AlgoLaser Alpha MK2. Make sure it sits level on your workspace and has ample room to rotate without obstruction.
1.2 Select the Appropriate Connecting Cable
Your ARC comes with a dedicated cable that links it to your engraver’s control board. Locate that cable in your accessories box.
1.3 Connect to the Y-Axis Terminal
Now, plug one end of the ARC cable into the Y-axis terminal on your Alpha MK2 laser engraver. Plug the other end into the ARC itself. This overrides the standard Y-axis movement and enables the rotary chuck to spin the mug during engraving.
1.4 Place the Motor Flat and Tighten the Knob
Ensure the motor side of the ARC is laid flat on the table. Then, gently rotate and tighten the knob underneath to lock it into position. A secure, flat base is critical for even engraving.
1.5 Adjust the Fixture Angle and Clamp the Mug
With your mug in hand, measure its diameter and align the ARC chuck accordingly. Gently open the chuck jaws, place the mug inside, and tighten the fixture knob to hold it in place. The grip should be firm, but not so tight that it damages the coating.
1.6 Adjust the Chuck Until It’s Level
Manually rotate the mug a few times and check that it stays horizontally level throughout the spin. If needed, tweak the chuck height or base alignment until it spins smoothly and evenly.
