xTool F1 Ultra FAQ: Rotary Tool, Leather Engraving, and the Plasma Cutter Question

If you're researching the xTool F1 Ultra, you're probably trying to separate the hype from the practical details. I run a small engraving shop, and I've been handling custom engraving orders for six years. For the past 18 months, the F1 Ultra has been the machine I use most. I've also made 14 trackable mistakes that totaled roughly $9,700 in wasted material and rework. Now I maintain the checklist we use before every job.

Honestly, this FAQ is the one I wish I'd found before buying. It covers the rotary tool, leather engraving, the difference between this machine and a plasma cutter, and why a 40W laser engraving machine isn't automatically the safer choice.

Questions I get asked constantly

• Is the xTool F1 Ultra laser cutter worth it for a small shop?
• Is the xTool F1 Ultra rotary tool worth it?
• Is the xTool F1 Ultra the best laser engraver for leather?
• Can the F1 Ultra replace a plasma cutter?
• Should I just buy a 40W laser engraving machine instead?
• What's the biggest mistake people make on the F1 Ultra?
• What's one thing I should check before every job?

1. Is the xTool F1 Ultra laser cutter worth it for a small shop?

If you're doing small-batch custom work, yes. But 'worth it' depends on what you're cutting. The F1 Ultra is a dual-laser machine: a fiber laser for metal marking and a diode laser for wood, leather, acrylic, and other organic materials. That combination means I don't have to switch between two machines for most orders.

I say 'laser cutter' carefully. It cuts thin materials well. I've cut 3mm basswood, 2mm acrylic, and light leather regularly. It's not a replacement for a heavy-duty cutter. The first month I owned it, I assumed 20W would slice through anything. It won't. I ruined a $200 batch of acrylic by trying to cut 6mm in one pass. That's the kind of mistake that led to our air assist checklist.

Before I bought this, I almost went with a 40W laser engraving machine because the wattage seemed like a stronger spec. In practice, the F1 Ultra's flexibility mattered more than raw power for the mixed orders we get.

2. Is the xTool F1 Ultra rotary tool worth it?

Yes, if you plan to engrave round items. The rotary attachment lets you engrave tumblers, bottles, rings, and pen blanks without rotating the item by hand. I skipped it on my first order to save money. Big mistake.

On a 32-piece tumbler order, I assumed I could manually rotate each tumbler and get consistent spacing. I couldn't. The result was a $620 order that went straight to the trash. The second time, I used the rotary tool and the job took under an hour. The lesson: buy the rotary attachment before you need it, not after.

One thing I learned the hard way: always verify the rotary setup before starting. If the item wobbles, the engraving will drift. Our checklist now includes a 5-second 'spin test' before any rotary run. That one check has saved us from at least four repeat jobs.

3. Is the xTool F1 Ultra the best laser engraver for leather?

For my shop, it's the one I'd choose. Leather engraving is where the diode laser really shines. I've used the F1 Ultra to engrave leather patches, dog collars, wallets, and belts. The key is to use low power and multiple passes instead of cranking the wattage.

I know 'low power' sounds boring. But the most frustrating part of leather is that every batch behaves differently. You'd think a saved preset would work every time, but veg-tan leather, chrome-tan, and dyed leather all react differently. I ruined a batch of veg-tan leather by assuming more power would make the engraving darker. It just scorched the surface.

If you mainly cut thick leather, a 40W laser engraving machine might cut faster. For detailed engraving on leather plus the ability to mark metal on the same machine, the F1 Ultra wins for me. Just test a scrap piece before every job.

4. Can the xTool F1 Ultra replace a plasma cutter?

No. This is the question I see constantly, and the answer is simple: a desktop dual-laser is not a plasma cutter. Plasma cutting temperature is a completely different category from what the F1 Ultra can produce. Plasma uses an electrically conductive gas to cut thick metal. The F1 Ultra uses a focused laser beam to mark or engrave metal, not to slice through steel plate.

I use the F1 Ultra for metal engraving and light metal marking. If a client asks for heavy steel cutting, I outsource it to a shop with the right tools. Trying to force a desktop laser into that job is a recipe for wasted time and damaged equipment. Know what the machine is for, and it'll serve you well.

5. Should I just buy a 40W laser engraving machine instead?

I almost did. A 40W laser engraving machine has more raw cutting power than the F1 Ultra's 20W diode side, so it seems like the obvious choice. But I found the opposite for our small-batch workflow.

Here's why: a dedicated 40W machine usually handles wood, acrylic, and leather, but it can't engrave metal. The F1 Ultra's fiber laser marks stainless steel, aluminum, and some coated metals without moving to another setup. For our order mix, that flexibility has been worth more than the extra cutting speed.

If you only cut wood and never touch metal, a 40W machine might be a better fit. But if you're like me and customers ask for 'a little bit of everything,' the dual-laser approach saves more time than a higher wattage.

6. What's the biggest mistake people make on the F1 Ultra?

Assuming the first settings you try are correct. I've done this more times than I want to admit. The F1 Ultra's official presets are a starting point, not a guarantee.

The mistake that cost me the most happened in March 2023. I engraved a $400 order of stainless steel tumblers using a preset from a forum post. The result looked great in the preview. On the actual tumblers, the contrast was too light because I didn't adjust for the specific tumbler coating. I had to redo the whole run with a slower speed and higher power. That's when I created our 'test first' rule.

5 minutes of verification beats 5 days of correction. Trust me on this one.

7. What's one thing I should check before every job?

Air assist, focus, and the material type. Air assist isn't a luxury—it keeps smoke off the lens and helps cut quality. I learned that after a batch of acrylic came out with melted edges because the air assist line had a small leak and I didn't check it. That mistake cost $150 in material and about four hours of rework.

Now our pre-flight check takes two minutes: clean the lens, verify focus with the included ruler, set air assist, and run a 5-second test on scrap. I know it sounds like overkill. But the 12-point checklist I created after my third mistake has saved us roughly $8,000 in potential rework over the past 18 months. The machine is easy to use—but easy to use isn't the same as impossible to mess up.
