xTool F2 Ultra 60W Fiber Complete Setup Guide: MOPA + Diode Dual Laser Workflow

xTool's F1 Ultra, covered elsewhere on this site, paired a 20W fiber module with a diode laser in one dual-source head. The F2 Ultra pushes the same idea further: a 60W MOPA fiber source and a 40W diode source sharing one galvo-driven gantry, in a machine aimed at shops that need both metal marking and wood/acrylic cutting without buying two separate machines. This guide covers assembly, the XCS software workflow, and getting a clean first result out of each laser source — it's a device-specific setup guide, not a repeat of this site's general fiber-marking technique content (see the MOPA color-marking guide for the physics of titanium oxide-layer marking, which applies here as much as on any other fiber source).

What MOPA Actually Buys You Over a Fixed-Pulse Fiber Laser

Most budget fiber lasers use a fixed-pulse-width source: the pulse duration is baked into the laser diode and can't be adjusted independently of power. A MOPA (Master Oscillator Power Amplifier) source decouples pulse width from power, so you can run a short pulse at high power for fine detail or a long pulse at lower power for color-marking work, without the compromises a fixed-pulse source forces. The F2 Ultra's 60W MOPA module is the reason it can do controlled color marking on titanium and stainless — a fixed-pulse 60W fiber laser would blow through the narrow parameter window color marking needs before you could dial it in.

Unboxing and Physical Setup

The F2 Ultra ships mostly pre-assembled on its enclosed frame, closer to the S1's assembly experience than the D1 Pro's open-frame kit build. Out of the box:

• Remove the gantry shipping brackets (zip-tied in two places on the X-axis rail) before powering on — running the homing cycle with these still attached is the single most common first-boot mistake on enclosed xTool machines.
• Connect the included fume extraction hose to a window vent or a dedicated extractor; the enclosure traps smoke effectively, which is good for light leakage but means diode cutting without active extraction will fog the lid within minutes.
• Level the included honeycomb bed if you'll be cutting (not just marking) — galvo marking doesn't need a perfectly flat bed since focus is handled optically within the field, but diode cutting through material to a backing surface does.
• Register the machine in xTool Creative Space (XCS) over WiFi or USB; XCS detects which of the two sources — fiber or diode — is active based on the layer settings you assign in the design.

XCS Workflow: One File, Two Laser Sources

The thing that takes new F2 Ultra owners the longest to get used to is that a single project file can mix fiber and diode layers — you might mark a stainless nameplate with the fiber source and then switch to diode to cut a wooden stand for it, all from one XCS document. Each layer gets assigned a source (Fiber or Diode) alongside the usual power/speed/pass settings, and XCS automatically prompts a reposition and refocus when you run a job that uses both in sequence. Don't try to run both simultaneously on the same pass — the machine only fires one source at a time, and XCS enforces that at the job-queue level.

First Job 1: Fiber-Engraving a Stainless Business Card Holder

Run XCS's built-in stainless preset at reduced power (50%) for your first pass on scrap before committing to the real piece — the F2 Ultra's galvo throws power down fast enough that an untested full-power pass on unfamiliar stock risks blowing out fine detail. A simple logo or line-art engrave at 50% power / 1000mm/s is a good calibration test: if lines look doubled or blurry, your Z-height (focus) is off, since galvo systems are far more focus-sensitive than their Cartesian equivalents.

First Job 2: Diode-Cutting a 3mm Acrylic Panel

Switch the active layer to Diode, confirm air assist is running (the F2 Ultra's air assist pump is built into the base, not a separate accessory you have to plumb in), and cut at the acrylic preset — typically around 15mm/s at 85% power for 2 passes on cast acrylic. Cast and extruded acrylic cut differently (extruded tends to haze more at the edge), so check which you have before trusting the preset blindly; this is covered in more depth in this site's general diode laser acrylic-cutting content.

Safety Notes

A 60W MOPA fiber source is a serious eye hazard outside the enclosure — this is not a laser you want to run with the lid propped open "just to watch," and the class-1 safety rating is only valid with the enclosure sealed and the safety glass undamaged. Reflections off bare metal stock are the main real-world risk during normal fiber use: clear loose reflective scrap from the bed before running a job, since a stray fiber reflection off foil or polished metal stays coherent at a distance in a way a diode reflection does not. For diode cutting, the usual rules apply — never leave the machine unattended on a cut, keep a CO2 or Class D extinguisher rated for the materials you're cutting nearby, and don't cut PVC, vinyl, or anything chlorinated with either source.

For a shop already running a dedicated CO2 or diode cutter for sheet work, the F2 Ultra's real pitch is the 220 × 220mm galvo field's speed advantage on detail and metal marking, not raw cutting capacity — it will not replace a Ray5 or a CO2 tube machine for cutting large panels, but it collapses "a fiber marker and a diode engraver" into one machine for anyone doing both small-format metal work and detail wood/acrylic engraving.
