Information

      Start your mornings with attitude and a strong cup of coffee ☕ 

These engraved slate coasters are made for caffeine lovers who run on bold brews and even bolder vibes.
Each coaster features a fun, laser-engraved coffee quote in crisp white lettering on natural black slate:
• HIGH OCTANE ONLY
• WAKE UP. SHOW UP. CAFFEINATE.
• LEAD UNLEADED.
• LIQUID AMBITION

Perfect for coffee bars, kitchen counters, office desks, or as a gift for that friend who is absolutely not a morning person without their brew.

Add a little paint over engraving and they look wonderful.

Instruction

Step1

Preparation

1. Clean the board

Slate is dusty. Wipe the coaster down with a damp cloth or a little isopropyl alcohol to remove loose stone dust. Let it dry completely.

2. The "Pre-Seal" Trick

For a darker, "wet look" background that makes the white engraving pop, apply a thin coat of clear matte or satin lacquer (spray can) to the slate before engraving. Let it dry for 20 minutes.

Step2

Software Setup

1. Import Your Design

Open the XCS file in xTool Studio
Resize the image to fit your coaster (standard coasters are usually 100mm x 100mm or 4" x 4"). Leave a small margin (e.g., size the design to 90mm).

2. Power & Speed Settings

Settings vary slightly by machine, but these are safe "starting points" for common xTool models. Always do a small test grid on the back of a coaster first.

Machine Model	Power	Speed	Lines Per cm (LPC)
xTool D1 / D1 Pro (10W)	80% - 100%	60 mm/s (3600 mm/m)	100 - 120
xTool D1 Pro (20W)	60% - 80%	80 mm/s (4800 mm/m)	120
xTool S1 (20W/40W)	40% - 60%	100 mm/s (6000 mm/m)	120
xTool F1 (Diode)	90% - 100%	150 mm/s	140

Note: If you are using "mm/m" (millimeters per minute) in your settings, multiply the speed above by 60.

Step3

Framing & Engraving

1. Focusing

Place the coaster in the machine.
Use the kickstand lever (D1/S1) or the auto-focus feature to set the correct laser height. Focus is critical for slate; if it's blurry, the engraving won't be bright white.

2. Framing

Click Framing in XCS.
Watch the laser boundary box trace the area on your coaster.
Adjust the coaster physically until the framing box is perfectly centered.

3. Engrave

Put on your safety goggles.
Click Process > Start.
Safety Note: Slate engraving produces a small amount of stone dust and smell. Ensure your exhaust fan is on or a window is open.

Step4

Post-Processing

1. Clean Up

When the laser finishes, the coaster will be covered in fine dust.
Take it to a sink and wash it with an old toothbrush (or soft sponge) and water. Scrub gently to remove the loose dust from the engraved grooves.

2. Final Protection

If you didn't pre-seal it, you can apply a light coat of clear lacquer now to protect the stone from wine stains (ironic, considering the design!).
Add felt or foam feet to the bottom corners to prevent scratching your table.
