Task-specific source comparisons
A bounded question, with its limits
A metal mark or an acrylic cut: choose the result first
These references have different source/process claims. A price or a power label cannot choose between two different desired results.
The B4 pilot retains a generic metal-marking statement; the MIRA reference has generic wood/acrylic cutting statements. Exact alloy/coating or clear-acrylic grade/thickness and the complete processing conditions remain unresolved. This pair is a source-scope lesson, not a suitability verdict or throughput contest.

Three different outcome questions
A separation through the material, shown conceptually.
A changed surface; this picture establishes no depth or processing capability.
A recess, shown without any depth, speed or quality claim.
Original explanatory cross-sections, not samples or operating instructions. Exact composition, coating, thickness and machine evidence are still required. Coating removal is a further distinct question.
What the supporting record says
ComMarker B4 20W configuration reference

body height mm: 350 mm · Source · 2026-11-07.
footprint length mm: 850 mm · Source · 2026-11-07.
footprint width mm: 530 mm · Source · 2026-11-07.

Evidence and complete costs
Reviewed test coverage and strict comparability rules
0 independently measured process pairs meet the strict retained material/condition comparability rules. Larger labels, different material claims and nominal speed figures are not an overall winner. Stock, many setup requirements and destination-specific charges remain unknown.
Use exact included contents and required-component status when planning the setup. A dated package observation is neither a current checkout total nor a complete operating cost. Do not transfer a lower-power price, generic accessory fit, regional policy or license entitlement across these references.
