Customer ratings

Budget powerhouse with strong cutting

Praised for very strong cutting power at a disruptive price. Large 400×400 mm area and fast traversal speeds stand out. Notes the missing limit switches and recommends external ventilation.

4.2/53dwithus.com
Strong specs, usability quirks

Highlights aggressive pricing, decent build, and capable engraving/cutting for the class. Flags usability drawbacks: lack of homing, app/hotspot limitations, and hose/shield interference.

4/5thephonograph.net
Great entry with caveats

Covers setup and operation with positive remarks on power and size. Emphasizes need for enclosure and third-party safety glasses; built-in filter not adequate.

3.9/5technicaltrendy.com
Performance focused, needs safety upgrades

Video tests show quick cuts on thin plywood and dark acrylic. Creator recommends air assist and an enclosure, and points out the hotspot Wi-Fi design as a nuisance.

4.1/5youtube.com
Engraving specialist

Users favor the 10W for finer text and photo engraving; slower and more passes needed for cutting >3 mm. Everyone stresses real ventilation and better goggles.

4/5thephonograph.net
Safety system unreliable

Multiple reports of unreliable flame detection (missed events/false alarms). Consensus: never leave unattended; treat detector as advisory only.

Conclusion

Illustration of a friendly robot analyzing laser cutters

The Elegoo Phecda 20W is a powerhouse for its price, delivering cutting performance that rivals much more expensive machines. It's best suited for experienced users who can overlook workflow limitations, like the absence of limit switches, in exchange for raw power and value.

FAQ

What’s the main difference between the Elegoo Phecda 10W and 20W?
💡
The 10W has a smaller, more symmetrical spot (~0.06×0.06 mm) that favors fine-detail engraving. The 20W combines diodes for higher cutting power (up to ~14 mm basswood under ideal conditions) but has a larger rectangular spot (~0.07×0.13 mm), so ultra-fine engraving detail is slightly lower.
Does the Phecda have limit switches and auto-homing?
💡
No. Both models ship without limit switches. You’ll set the job origin manually each time. Aftermarket limit-switch kits can add homing, repeatability, and crash protection.
Can it engrave/cut clear or light acrylic?
💡
No. As a ~455 nm blue diode, it won’t absorb in clear or light acrylic. It can cut/engrave dark/opaque acrylics well (better with air assist).
Is the built-in smoke filter enough for indoor use?
💡
No. It reduces odor a bit but doesn’t capture most smoke/particulates. Use an enclosure and vent outside or a proper multi-stage fume extractor.
How reliable is the flame detector?
💡
User reports are mixed; several note missed events or false positives. Treat it as supplemental only—never leave jobs unattended and keep a fire extinguisher handy.
How does Wi-Fi work on the Phecda?
💡
It creates its own hotspot for the app. Your phone connects to that network (no internet during use). Many users prefer USB or TF card for reliability.
What software is supported?
💡
LightBurn and LaserGRBL for desktop workflows, plus Elegoo’s mobile app for basic jobs over Wi-Fi.
Is there autofocus?
💡
No. Focusing is manual via a fold-down positioning bar. It’s simple and repeatable once learned.
What realistic cutting performance should I expect?
💡
20W: confident on 3–6 mm plywood and dark acrylic; thicker woods need multiple passes and good air assist. 10W: good engraving, light cutting (e.g., 2–3 mm plywood/leather/cardstock).
What safety gear do I need?
💡
It’s a Class 4 laser. Use certified 455 nm-rated goggles, an enclosure, external ventilation, and never leave the machine unattended.
Does it support a rotary?
💡
Yes, with an optional rotary attachment for tumblers, glasses, dowels, etc.
What’s the real-world top speed?
💡
Traverse speeds can be very high (e.g., up to ~25,000 mm/min on X), but quality engraving/cutting usually happens at lower speeds for adequate energy deposition.
Any workflow gotchas?
💡
Without homing, you must re-set origin for each job. Manage the air-assist hose/cables to avoid snags; many users re-route or add guides.
What’s the warranty like?
💡
12 months for the machine; several parts are treated as consumables with limited or no coverage (e.g., belts, mirrors, filters).
