The ACMER P2 33W is a 33W diode laser engraver. This page lists 7 community-tested settings covering speed, power, passes, air assist, and DPI across a range of materials. Always run a test cut on scrap material first — results vary depending on your material batch, focus, and ambient conditions.
Removes anodized coating, revealing bare metal underneath. High contrast result. 33W machine needs lower power than weaker diodes for same anodize removal — start low and test. Works on black, red, green, and gold anodize. Wipe with microfiber after for crisp reveal.
Opaque black acrylic only — 450nm diode passes through clear acrylic. With 33W and air assist, cuts cleanly in a single pass at high speed. Remove protective paper before cutting. Constant power mode. Check for slight haze on edge — remove masking immediately if present.
Veg-tan leather only. 33W is powerful — keep speed high and power moderate to avoid burning through. Test on scrap first; hide thickness varies significantly. Never use chrome-tanned leather (toxic fumes). Dynamic power mode.
Tested directly on stainless steel at 200mm/min, 100% power, 1 pass with air assist on. Result: legible text/marks. Varying power and line interval (0.05–0.1mm) produces color oxidation effects (blues, oranges, purples) — a standout feature of the P2's high power. Black acrylic paint pre-coating not required at full power.
High speed engrave leveraging the P2's 30,000mm/min rated speed and linear guide rails. Use dynamic power mode. Result: good contrast with minimal charring. Bump to 55% for deeper/darker mark. Always run a material test grid first.
33W cuts 3mm MDF cleanly in one pass with air assist. MDF produces heavy fumes — ventilate well. Air assist critical to prevent flare-up and keep lens clean. Multiple fast passes are an alternative for cleaner edges on thicker MDF (8mm: 2 passes).
33W with included air assist makes light work of 3mm basswood in a single pass. Optimal range tested: 70–100% power at 800–1100mm/min. Air assist included as standard — always use it for cutting. Constant power mode. Check flatness of sheet.
"Used it with a Glowforge — engraved beautifully with no changes. I will be purchasing more digital downloads from this shop."

"This template made my slate coasters so much easier. 4×4 coasters from Michaels drop in easily and are easy to remove. Def worth it."
