How to Laser Engrave a Stainless Steel Coated Mug for Dad
There’s something truly special about creating a custom gift with your own hands—especially for someone as important as Dad. Whether it’s Father’s Day, a birthday, or just because, engraving a personalized message or design on a stainless steel coated mug makes for a one-of-a-kind gift that will last a lifetime. Thanks to diode laser technology, and more specifically the AlgoLaser Alpha MK2 20W laser engraver, this kind of project is easier and more rewarding than ever.
In this detailed blog post, we’ll walk you through 5 professional-level steps on how to laser engrave a stainless steel coated mug using the ARC rotary tool with the Alpha MK2. We’ll also share real-world engraving settings, expert tips, and answer six of the most frequently asked questions to help you succeed on your first try.
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.
Proper focusing and system settings are what turn an average engraving into a masterpiece. Here’s how to set up the Alpha MK2 for success:
2.1 Use the Focal Gauge to Adjust the Focus
Place the focal gauge (usually a flat acrylic or metal plate) between the laser head and the mug surface. Adjust the height of the laser module until it just touches the gauge, then remove it. This ensures your laser is focused at the optimal distance.
2.2 Set ARC Chuck Mode
On the touchscreen interface of your Alpha MK2, tap “Settings” > “Machine” > “Working Mode” and select “ARC Chuck Mode.” This tells the machine you’ll be engraving on a cylindrical object using a rotary tool.
2.3 Input the Correct Calibre Value
The "calibre value" refers to the diameter of your mug, which ensures accurate rotational speed. For example, if your mug’s diameter is 84mm, input “84” in the calibre field.
2.4 Return to the Home Page
Once your settings are saved, head back to the home screen. You’re ready to start designing!
This is where the magic happens—your custom design or heartfelt message takes shape.
3.1 Click “Projects” > “SD Card”
Navigate to the Projects menu and select “SD Card.” This is where you’ll find your stored design files. If you’re importing a file, make sure it’s in GCode or compatible SVG format.
3.2 Select a Picture
Pick a graphic or message that Dad will love—perhaps a monogram, a favorite quote, or an image like a fishing rod or hammer.
3.3 Select Material and Engraving Effect
Choose “Stainless Steel Coated Mug” as your material. Then pick your desired effect—either grayscale fill or line art. We recommend fill engraving for bold designs or text.
3.4 Set the Size and Position
Adjust the size and positioning of your design so it fits well on the curved surface of the mug. A width of 60-80mm is usually ideal for most mugs.
3.5 Preview with the Frame Button
Click the frame icon to preview the engraving area. The laser head will trace the border of your design so you can make sure it aligns correctly on the mug. If it looks good, hit confirm.
With the design locked in and everything aligned, it’s time to let the Alpha MK2 do what it does best.
4.1 Click “Start” to Begin Engraving
Simply tap the Start button and watch as the rotary tool begins spinning the mug while the laser head engraves the coating off the surface. It’s mesmerizing to see your design come to life with precision.
4.2 Monitor the Progress
While engraving, stay nearby to monitor progress. Listen for any odd sounds or slipping. If something looks off, hit pause immediately.
4.3 Clean the Mug Once Finished
Once the engraving finishes, let the mug cool down and gently remove it from the ARC. Use a soft cloth to wipe off any residue. If needed, use a bit of rubbing alcohol for tougher soot.
To help you get a clean, high-contrast finish on a stainless steel coated mug, here are the tested settings using the AlgoLaser Alpha MK2 20W:
· Material: Stainless Steel Coated Mug
· Power: 100%
· Speed: 15,000 mm/min
· Passes: 1
· Working Mode: ARC Chuck Mode
· Focal Length: Calibrated with focus gauge
· Calibre Value: Match your mug’s diameter (e.g., 84mm)
Note: No need to add additional coating like marking spray—many stainless steel mugs come with a coating that will react directly with the laser, leaving a clean, white, or metallic mark.
1. Can I engrave on plain stainless steel without a coating?
Not with a diode laser like the Alpha MK2. You’ll need to use a marking spray like LaserBond or CerMark to etch bare stainless steel.
2. Why is my mug slipping in the ARC chuck?
Check that the fixture knob is tight, the chuck is level, and the mug’s diameter matches your settings. Even a small tilt can cause slipping during rotation.
3. How long does it take to engrave a mug?
On average, a filled design will take about 5 to 10 minutes, depending on size and complexity.
4. Do I need a rotary tool for mugs?
Yes, definitely. Cylindrical items must rotate during engraving or else the laser won’t maintain proper focus across the surface.
5. Will the engraving fade or wash off?
Nope. The laser removes part of the coating or bonds with it, creating a permanent mark that won’t wash off or fade with time.
6. What design software should I use?
AlgoLaser's built-in software works well, or you can design in LightBurn, export the file as GCode, and then load it to the SD card of the Alpha MK2.
Laser engraving a stainless steel coated mug isn’t just about the tool—it’s about the thought, care, and creativity you bring to the table. With the AlgoLaser Alpha MK2 20W laser engraver and the ARC rotary chuck, you’re not just gifting a mug. You’re delivering a personalized memory that Dad will treasure every morning with his coffee or tea.
