The number everyone misreads: what wattage really controls, and why diode watts and CO2 watts are not the same thing.
Read the guideXTool S1 vs Glowforge Aura in 2026: Which One Is Yours
xTool S1 vs Glowforge Aura compares two rungs of one sealed diode ladder. The S1 is the 40 watt class rung with a mid size bed and desktop software. The Aura is the compact single-digit watt rung with a foot square bed, and ambition decides.

What does each machine really cost, once the bench is stocked?
Both machines live in the middle of the laser money map, but on different floors. The xTool S1 sits at the premium price point of the enclosed diode class, because a 40 watt class engine, a mid size bed, and an appliance grade shell cost real money to bolt together. The Glowforge Aura sits at the budget door of the Glowforge family and asks the smaller ticket of the two, because a single digit watt engine on a compact bed is simply cheaper to build. Same safety philosophy, two budgets, and the gap is hardware, not marketing.
Where the money really goes is after the box lands, and it runs the same direction on both sides. Both machines are sealed for light, not for smoke, so each one wants a hose to a window or a place in a filter box before the first real run. Add a rotary attachment the week tumblers arrive, honeycomb or a raised worktable if you cut, and blanks in every flavor, and the machine becomes the cheap part of the hobby faster than you expect.
So price the two against your calendar, not against each other. The S1 premium makes sense when hours of engraving and bigger batches sit in your near future, and the Aura saving makes sense when the bench is a desk and the orders are gifts. Nobody loses money buying the honest size; everyone loses money buying the wrong ambition.
The way I see it
One box is the full chef knife set that lives by the cutting board, and the other is the folding knife that rides in a coat pocket. Both will slice a bagel beautifully, but only one is ready when the bagel orders start coming in by the dozen.
Which machine matches the way you make right now?
The family tree is short and honest: the S1 and the Aura are both enclosed diode machines with interlocked lids and a beginner friendly promise. What they are not is interchangeable, because engine size and table size split them into two different buyers. Same species, very different habitats.
The xTool S1: the enclosed diode with the big bench
The S1 is the 40 watt class engine of the sealed diode lane, wrapped in a shell with an interlocked lid, a viewing window, and a mid size bed that clears cutting boards, sign blanks, and a row of tumblers in one pass. The air assist pump ships inside the box, and a rear port takes the fume extractor once the runs start smelling. This is the machine you graduate to, not the one you outgrow.
It runs on the brand desktop app, which works happily offline and never asks for a subscription, with a preset library deep enough to skip the guesswork. The rotary family handles round stock, and the whole package behaves like a bench tool with a queue in mind, not a toy waiting on a safety build. The software stays free and the machine stays the star of the bench.
The Glowforge Aura: the compact cube with the friendly face
The Aura is the compact single digit watt diode at the bottom of the Glowforge family, wrapped in a light self enclosed body with a bed roughly a foot square. Coasters, keychains, ornaments, plaques, and one mug at a time are its home turf, and the cloud guided app previews the job and dials the settings for you. It is the least intimidating door into the hobby, full stop.
It is quiet enough for a desk in a shared room, it pairs with the brand rotary for round blanks one piece at a time, and the add on filter from the same family keeps the smell out of the house. The trade is honest: it engraves beautifully and cuts thin craft stock in patient passes, so treat cutting as a bonus rather than the headline. The cube is not a smaller S1, it is a different job description.
Think of it this way
Same breed, two sizes. The S1 is the big dog that wants a yard and a walk schedule, and the Aura is the small dog that thrives in an apartment. Both are house trained, both are loyal, and only one matches the square footage you actually own.
What does the wattage gap buy you on the bench?
Start with what the two share, because it stops a lot of bad shopping. Both shoot the same blue diode band of light, which means both love wood, leather, paper, and coated metal, and both walk straight through clear acrylic and bare glass like the beam is a ghost. The S1 will not unlock a single material the Aura cannot touch, and that is the honest headline of this whole page. The difference is not the menu, it is the appetite.
Now add the watts. The 40 watt class engine engraves a good deal faster than the single digit class and pushes through thin hardwood in passes where the compact cube nibbles. The Aura finishes a set of coasters beautifully in an evening, and the S1 finishes the same set and starts the next batch before you refill your cup. Bed size multiplies the effect, because the S1 fills a mid size bed while the Aura reloads its compact plate in rounds.
The brains part company too. The Aura wants the cloud: upload, preview, and print all flow through the Glowforge app, which is gorgeous until the wifi sulks. The S1 runs from the desktop, works offline, and keeps your files on your own drive. Neither lane is wrong, but only one suits a workshop that must not stop.
Read the chart the way a shopper should. The top three rows are the S1 argument, and the bottom two are the Aura argument, and your project list already knows which half it lives in. If you hesitated on either half, the rest of this page settles it.
Think of it this way
Watts are torque on the same set of drill bits. A cordless screwdriver and a corded drill turn the same screws, but only one powers through oak all afternoon without slowing. The Aura is the screwdriver, the S1 is the drill, and your job list picks which one you carry.
How do you pick one from the jobs you actually run?
Skip brand loyalty and answer five questions against your real order history. The machine that matches your last fifty projects will beat the machine that impresses your neighbor. Receipts are honest, ads are not.
- Write down your top ten projects and their sizes. Full signs and cutting boards point at the S1, while coasters, ornaments, and mugs fit the compact Aura plate with room to spare. Size the bed to the stock, not to the dream.
- Count the hours behind your orders. If you sell pace, the 40 watt class gives your evenings back; if you make gifts, the gentle rhythm of the compact cube never embarrasses you. Speed is only money when your time is on the clock.
- Look at the round things in your queue. Tumbler runs in rows want the S1 with the rotary family, while one mug at a time is the Aura lane. Both drink from the same round stock, at very different rates.
- Test your wifi faith honestly. The Aura is cloud first by design, and the S1 runs offline from the desktop. Router tantrums are a design feature on exactly one side.
- Measure the room, not the brochure. A desk in a shared space votes for the Aura, and a bench with a vent path votes for the S1. The best machine in the world is the one that fits the room you have.
See the pattern in the bars. The Aura owns the gift table and the small room rows, and the S1 owns the workshop rows, which means the honest tiebreaker is growth: the S1 handles both worlds, while the Aura handles one of them beautifully.
The way I see it
The Aura is the single group espresso machine that makes the morning cup a ritual, and the S1 is the two group machine that keeps the queue moving once the orders arrive. Buy the one that matches the cups you actually serve, not the barista you dream of being.
Which one earns its keep for the work you do?
Split the worth question by whose bench the box lands on, because the same machine that pays rent in one room gathers dust in another. Worth is decided by the job list, not the sticker. Each machine is only worth what it actually runs for you.
The xTool S1 buyer
The S1 earns its premium the week your job list reads like a shop: signs, cutting boards, tumbler runs, and coated metal tags, in batches that want a bigger bed and a faster beam. It suits the maker who treats the laser as a tool with a queue, who likes desktop software and offline evenings, and who plans to grow into the accessory shelf instead of out of it. Buy it for the bench you are building, not the bench you have.
Buy It If
- Buy the S1 if your list is wood signs, cutting boards, and tumbler runs that want a mid size bed and the pace of the 40 watt class.
- Buy the S1 if you want desktop software that works offline and a machine with headroom for bigger stock and longer runs.
- Buy the S1 if you plan to grow into the rotary and fume family instead of outgrowing the machine.
Skip It If
- Skip the S1 if your catalog is all coasters and keychains, because the premium engine idles through jobs the compact cube finishes happily.
- Skip the S1 if the only home is a ventless desk corner, because this machine earns its keep on a real bench with an airflow plan.
- Skip the S1 if the premium ticket would empty the material drawer, because the machine that runs every week beats the one that only impresses monthly.
The Glowforge Aura buyer
The Aura earns its keep the week your job list reads like a gift table: coasters, ornaments, keychains, and engraved keepsakes, made one careful round at a time in a corner of the house. It suits the first timer who wants the guided cloud flow, the small space dweller who cannot spare a bench, and the maker whose money goes further in blanks than in watts. The cube is the right size for that ambition, and that is a compliment.
Buy It If
- Buy the Aura if your list is engraved gifts and keepsakes at desk scale, made one at a time in a small space.
- Buy the Aura if the guided cloud flow is the feature you want, because the app holds your hand through the first hundred jobs.
- Buy the Aura if the smaller ticket leaves more budget for blanks, a filter, and a rotary, which is where the hobby actually grows.
Skip It If
- Skip the Aura if your orders already run in rows, because the compact bed turns every batch into a slow evening ritual.
- Skip the Aura if you need offline evenings, because the cloud is the only road this machine is built around.
- Skip the Aura if thick hardwood cutting is the headline, because the single digit class engraves for a living and cuts as a courtesy.
Read both lists together and the verdict is already forming. Both machines are fairly priced for their job descriptions; the expensive mistake is buying the bigger one for a small list or the smaller one for a growing one. One rule covers the pair: if clear acrylic or bare glass is the bread and butter, neither diode on this page is the machine, that is a CO2 conversation for another day. Match the ambition, and the money follows.
Which machine wins each round, side by side?
Stack the two on the axes that settle the sale: engine, bed, software, and the job list each machine serves. One wins the workshop rows, the other wins the gift table rows, and the table calls it row by row so the bias stays out of it.
| Option or Product | Engine and pace | Bed and software | Best For | Verdict |
|---|---|---|---|---|
| xTool S1 | 40 watt class diode, fast engraving, thin to medium stock cutting | Mid size bed, offline friendly desktop app | Signs, boards, tumbler runs, growing batches | The workshop winner: bring the queue and it will clear it. |
| Glowforge Aura | Single digit watt diode, gentle engraving pace | Compact bed, guided cloud app | Gifts, keepsakes, small stock, first timers | The desk winner: small, guided, and exactly enough for a gift table. |
Two fair notes before you leave the table. The S1 asks the premium money because it delivers premium pace and room, and the Aura costs less because it promises less and keeps that promise. There is no loser here, only a job list you have not measured yet.
Which one do you bring home this year?
Declare the reader first: this verdict is for the maker with a real bench and a job list that keeps growing, signs and boards today, tumblers and bigger stock tomorrow, who wants one safe enclosed machine to grow into rather than out of. For that reader the answer is the xTool S1: the pace of the 40 watt class, the mid size bed, and the offline desktop software line up with the work, and the premium price point buys years of headroom. It is the machine you will still be glad you bought in year three.
Now the honest counter, because the loser of this page is the winner of another one. The Glowforge Aura is the right call when the catalog is engraved gifts, the space is a desk in a shared room, and the budget is the whole story. It costs less, fits a shelf, guides a first timer through the first week, and never apologizes for its size. The Aura is not a smaller S1; it is the right size for a different ambition.
The Bottom Line
Bottom line: the xTool S1 wins this head to head for the maker with a growing bench and a real job list, because the pace of the 40 watt class, the mid size bed, and the offline friendly desktop software turn hours into batches. The Glowforge Aura wins for the gift maker in a small space who wants the guided cloud flow and the smaller ticket. Buy the ambition you can fill, not the one the ads fill for you.
