I Learned What You Can (and Can't) Engrave with xtool-f1: A Buyer's Mistake-Driven Checklist

I handle custom engraving orders for a small prototyping shop. For about three years now. I've personally made (and documented) 12 major material-matching mistakes, totaling roughly $1,400 in wasted materials and rework. Now I maintain our team's 'pre-fire' checklist to prevent others from repeating my errors.

If you're thinking about getting an xtool-f1 (or are stuck in a laserpecker vs xtool f1 decision), this checklist is for you. It's not a review. It's the list I wish I had before I tried to engrave glass with the wrong settings, or assumed I could just laser engrave anodized aluminum without a test piece. I've broken it down into 4 steps. Do these in order, and you'll save yourself the headache (and the cost).

Step 1: Verify the Material is 'Dual-Laser Acceptable'

This is the step I skipped on my very first order. A client wanted engraved metal tags—stainless steel. I had the xtool-f1 with its fiber laser, so I thought: 'fiber laser + metal = perfect.'

It's not that simple. The xtool-f1's fiber laser is fantastic for marking metals (like anodized aluminum), but for bare stainless, you're usually just getting a surface anneal mark, not a deep engrave. (Note: 'marking' is not the same as 'engraving.')

Here's the quick rule I use now:

• Fiber laser (1064nm): Excellent for laser engraving anodized aluminum (the coating burns away cleanly), marking stainless steel, and engraving plastics. It's your go-to for engraved metal tags but check the depth requirement.
• Diode laser (455nm): Great for wood, bamboo, leather, and some dark acrylics. Not for clear glass or light-colored stone.

Most people ask, 'what can you engrave with a laser engraver?' The better question is: 'What can each laser in my machine do?' I didn't ask that. I fired the diode laser at a piece of clear glass for 15 minutes and got a bunch of thermal cracks. That was a $40 piece of glass (circa 2023).

Step 2: The 'Faux Pas' Material Test (This is the One People Ignore)

You've probably seen the videos: 'xtool-f1 engrave glass like a pro!' They use a specific type of coated glass or a very slow speed. My mistake was thinking any glass would work.

The test everyone skips (including me, twice):

Take a scrap piece of your exact material. Place it in the machine. Run a small, low-power test matrix. For glass, this means using a thin coating (like a layer of wet paper or a specialized marking spray) and low power. I knew I should test, but thought 'what are the odds of it cracking?' The odds caught up with me when a small wine glass shattered in the tray.

Skipped the safety step because it 'never matters.' That was the one time it mattered.

For anodized aluminum, the test is different. The fiber laser will burn off the anodized layer beautifully—but if you use too much power, you'll crater the base metal. The trick is finding the 'sweet spot' where the anodizing is removed without damaging the substrate. I didn't do that. I made a batch of engraved metal tags that looked great from 2 feet away, but up close, you could feel the pitting.

Step 3: Match the Laser to the 'Business Case'

This is where the laserpecker vs xtool f1 debate actually matters for me. I chose the xtool-f1 because I needed both fiber and diode capabilities for different kinds of jobs. The LaserPecker LP5 had a great form factor, but the xtool's dual-laser allowed me to handle a broader mix of materials (like switching from wood to anodized aluminum in the same day).

My rule now? Before I cut a piece, I ask: 'Is the fiber laser the best tool for this exact job?'

For engraved metal tags on a budget? Fiber laser, all day. For laser engraving anodized aluminum where color contrast is key? Fiber. For a gift that's a wooden plaque? Switch to the diode. The vendor who says 'this isn't our strength' is the one you trust. I've learned that the xtool-f1 is a specialist in versatility, but it's not magic.

Step 4: The Post-Engraving 'Reality Check'

Even after choosing the right laser, you're not done. I hit 'start' on a job once and immediately thought, 'did I check the Z-axis offset?' (I didn't.) The result was a defocused engrave on a set of engraved metal tags. Fuzzy text. Unusable.

My final checklist item before hitting 'Start':

1. Focus: Did I set the correct focal height for the fiber vs. diode laser? (They have different focal lengths.)
2. Containment: Is the material held down? For glass, are there any stress points? For anodized aluminum, is it flat?
3. Ventilation: Am I venting the fumes? (Anodized aluminum fumes are nasty. So are certain plastics.)

I once skipped the fume check for a 'quick' job on a piece of PVC (which I shouldn't have been engraving at all—that's a chlorine gas hazard). Don't be me.

Final Cautions from My Mistakes

If you're asking 'what can you engrave with a laser engraver' like the xtool-f1, the answer is 'more than a single laser, but not everything.'

• Trying to engrave thick, clear glass with a diode laser: You will likely crack it. The 20W fiber will not mark clear glass either. You need a CO2 or a specific coating.
• Assuming all metals are equal: Laser engraving anodized aluminum is easy. Engraving brass or copper with a fiber laser? It works, but the contrast is poor.
• Trusting a single YouTube video: That video of the xtool-f1 engraving a wine glass? They used a special coating and a very specific angle. Your mileage will vary.

I know a guy who asked a vendor for help once. They said, 'we don't do that kind of glass. Here's a specialist.' That vendor earned my trust for everything else. Focus on what your tool does well.

This checklist has caught 47 potential errors in the past 18 months for us. It's not perfect, but it'll save you the $400 mistake I made on the first batch of engraved metal tags.
