TL;DR
The GM 20W is the low-cost model on Monport's GM Pro page: an integrated 20W fiber with manual focus and a 110 × 110 mm field, $1,410 on Monport's store in October 2026. It suits tags, jewelry and small tools. Monport gives few figures for it: no source brand, depth or weight on the product page, so treat it as a budget marker rather than an engraving machine.

What makes this machine stand out
Hardware and workflow features worth understanding before you buy : not just wattage on a label.
Monport's cheapest fiber
At $1,410 in October 2026, the GM 20W is the least expensive way into Monport's fiber range, with the same rotary and LightBurn bundle options as the Pro tiers.
Sized for small parts
The 110 × 110 mm field covers tags, rings, pendants, keys and small tools, the bread-and-butter of a home or market-stall marking business.
Our verdict
Ideal if you
The GM 20W makes sense for a small marking side business on a strict budget: tags, jewelry and tools fit its field, and the price leaves room for an enclosure and safety gear.
Skip if you
Manual focus slows mixed-height work, the field is small, and Monport publishes few specifications for this model. Anyone planning deep engraving should look at a higher-power tier.
Pros
- Lowest price in Monport's fiber range at $1,410 (Monport store, Oct 2026)
- Integrated one-piece design: source, galvo and column on a single base
- Rotary and LightBurn bundles offered at the same small price steps as the Pro tiers
Cons
- Manual focus: height is set by hand for every new part
- Small 110 × 110 mm field, limiting for tumblers and larger plates
- Specs largely missing from the product page: source, marking depth and weight are not listed

Pro tips
Use the red-dot preview and a focus gauge to set height precisely on each part type, then note the value for repeat jobs.

Common questions
What does the GM 20W lack compared with the GM Pro tiers?
Autofocus and the electric lift: focus is set manually. The field is also smaller (110 × 110 mm instead of 150 × 150 mm), and Monport does not publish its source, depth or pulse figures in the comparison table that covers the Pro tiers.
Can the GM 20W engrave deeply or cut metal?
It is not meant for that. A 20W Q-switched fiber marks and lightly engraves metal; deep relief and thin-sheet cut-outs take many passes and are better left to the higher-power tiers.
Is the GM 20W worth it over a 20W integrated fiber from another brand?
It is priced in the same range as Gweike's G2 20W ($1,299) and close to the ComMarker B4 20W ($1,399). The GM 20W's case rests on Monport's US support and bundles; the published specs are thinner than its rivals', so compare field size and focus type before buying.
