If you are reading this, you are probably staring at the xTool F1 Ultra. That 20W fiber and diode dual laser thing. You have seen the promo videos. You want to cut metal. You also do not want to blow your annual procurement budget on a machine that ends up being a glorified paperweight.
I get it. As the person who signs off on purchases for my company, I have learned that the gap between a product's marketing and its actual utility can be a very expensive canyon. This checklist is for you. It is for the cautious buyer, the admin who has been burned by a vendor who could not provide a proper invoice, and the small business owner who needs this tool to actually work on Monday morning.
Here is a practical, step-by-step guide on how to evaluate, set up, and start *actually* using the F1 Ultra. There are four steps. Do not skip step three.
Step 1: The Unboxing and Reality Check
First, ignore the hype for a minute. The F1 Ultra is a desktop machine. It is heavy, about 11kg (24lbs). Make sure your desk can handle it. It is not a shop floor tool. It is a precision instrument for a clean office or a small workshop.
When you open the box, do not just plug it in. do this instead:
- Inspect the enclosure. The safety lid and the honeycomb worktable. Is everything snug? This is your first hint at build quality. If the lid feels loose, that is a red flag.
- Check the lens. The fiber laser module and the diode module. There are two distinct laser sources here. Make sure they are clean and seated correctly. The manual shows you how. Actually read that part.
- Find the air assist connection. This is critical for cutting. Without it, you will get charred edges on wood and poor cuts on acrylic. Make sure the pump and tubing are in the box.
Honestly, I am not sure why some units ship with the air assist tube slightly kinked. My best guess is it happens during packing. Just check it. It is a five-second fix that saves a lot of frustration.
Step 2: The Software Setup and the One Weird Trick
Set up the xTool Creative Space software. It is free and works on Mac and Windows. You will connect via USB or Wi-Fi. Use USB for the first test. Wi-Fi can be flaky if your network has a lot of devices. I always start with USB to eliminate a variable.
Now, for the weird trick. People think you need to calibrate the laser every time you change materials. That is a myth. This was true maybe five years ago on older CO2 lasers. Today, the F1 Ultra with its dual lasers is much more stable. You *do* need to set the correct focus distance, but you do not need to re-run a full calibration grid each time. Save yourself 20 minutes.
Here is what you actually need to do:
- Load the material on the honeycomb bed.
- Use the manual focus tool (a little plastic wedge that comes in the box) to set the correct height. The laser head should just kiss the wedge.
- Select the material profile in the software. Start with the default settings. Do not touch them yet.
The assumption is that you need to customize every setting. The reality is that xTool's pre-sets for the F1 Ultra are surprisingly good for a first pass. If your first test looks bad, it is almost always a focus problem, not a power problem.
Step 3: The Material Test That Most People Skip (And This Is The Critical One)
Here is the step that most YouTube reviews gloss over. Do not just cut your final project. Cut a test grid. I use a small scrap piece of the same material. This is not new advice, but the *way* you test matters.
People think testing means trying a few different power levels. That is wrong. The real variable is speed vs. passes. The F1 Ultra is powerful, but it is not a 100W CO2 laser. You are not going to cut 10mm plywood in a single pass.
- For wood (e.g., 3mm basswood ply): Start at 100% power, 200 mm/s speed. If it does not cut through, do not increase power. Decrease speed to 150 mm/s. If it still does not cut, increase the number of passes to 2.
- For metal marking (e.g., a Yeti cup): You are going to use the 20W Fiber laser. Power at 100%, speed at 1000 mm/s, frequency around 70kHz. This will mark the powder coating without damaging it. For a deeper etch on bare metal, slow it down to 200 mm/s.
The surprise was not the power of the fiber laser. It was how well the 20W diode handles acrylic. I never expected a diode laser to do clear acrylic, but with the right settings and a pass, it works. Not perfectly like a CO2 tube, but well enough for small parts and prototypes.
Quick note on 'home laser welder' and 'best cheap laser engraver'. The F1 Ultra is not a laser welder. Do not confuse it with one. It is an engraver and a cutter of thin materials. It is also not 'cheap'. It is affordable for what it does, but it is a professional tool, not a hobbyist toy. If you are looking for a sub-$200 engraver to mark coasters, this is overkill. If you need to mark metal and cut thin acrylic in a small office, it is the best value.
Step 4: Workflow and Safety (The Boring but Necessary Part)
Once you have your test grid dialed in, you can start working. But first, workflow. This machine creates fumes. The built-in fan and filter system is okay for a small office, but do not run it for hours in a closed room. Crack a window. We had a vendor once who could not handle simple compliance requests. I do not want you to be that vendor for your safety officer.
Set up a file management system. I name my files with the material, power, speed, and date. 'Wood_3mm_100p_200s_1p_20250115.afdesign'. Sounds obsessive, but when you need to re-cut a part six months later, you will thank me.
Cost Reference: The xTool F1 Ultra itself is around $1,500–$1,800 depending on the bundle (based on mfr. list price, Jan 2025; verify current pricing). That is in the range of a good professional printer. The consumables—laser module replacements (not cheap), air assist filters, and the rotary attachment for Yeti cups—add up. Budget another $200–$400 for accessories and consumables in the first year.
To compare, a standalone fiber laser for metal marking can cost 3x this. The F1 Ultra's strength is being two lasers in one box. Its weakness is that it is not exceptional at either job compared to a dedicated machine. But for a general-purpose office tool? It is a solid 8 out of 10.
Common Mistakes and Final Notes
I've mentioned a few, but here is the condensed list of things that will trip you up:
- Forgetting to focus. The software will yell at you if the lid is open, but it will not check focus. Always use the wedge.
- Fire hazard. Do not leave the machine running unattended. The enclosure is fire-resistant, but thin plywood and paper can still catch fire if the settings are too aggressive. I keep a small CO2 extinguisher nearby. Not a water one, obviously.
- The rotary attachment. It works, but the calibration is fiddly. Set aside an hour to get it right for your first Yeti cup. Do not expect it to be plug-and-play.
The xTool F1 Ultra is a capable machine if you treat it like a precision tool and not a magic wand. It fits a specific niche: the small business or office that needs to mark metal and cut thin materials without buying two separate machines. It is not the best cheap laser engraver. It is the best *versatile* laser engraver for a specific kind of buyer—the cautious one who does their homework first.
