What this machine will and will not work
| Mild steel Capable | **Marking only - never cutting.** Mild steel is what this head is on the machine for. Long pulses at 200 ns and 20 kHz at roughly 300 mm/s anneal a black oxide mark into the surface without removing material, which is the mark that survives handling and light corrosion. Short pulses at 4 ns and 60 kHz at 800 mm/s engrave a frosted or dark grey mark 0.005 to 0.02 mm deep in several passes. Serial numbers, data-matrix codes, logos, scales and tool identification are all routine. It **cannot cut mild steel** in any thickness. Cutting metal with light needs a kilowatt-class source and an oxygen or nitrogen assist jet; 30 W of average power with a cross-jet of clean air is three orders of magnitude away from that, and nothing in the parameter set closes the gap. Mill scale must be wire-brushed off before marking or the mark is in the scale and wipes away with it. |
|---|---|
| Steel Capable | **Marking only - never cutting.** Stainless in the 304 and 316 groups anneals to a stable black at 200 ns and about 250 mm/s, and takes colour marks - straw, brown, blue - at intermediate energies, which is a temperature effect in the oxide layer and is repeatable once a parameter set is proved. Tool steels and hardened material mark exactly as well as soft ones, because marking is a surface energy process and hardness is irrelevant to it - which is the one thing this head does that the spindle head cannot do at all above 30 HRC. Cutting is not possible, for the same physics as mild steel. A corrosion note that matters on stainless: an annealed mark is an oxide layer, and on 316 in a wet or chlorinated environment an engraved mark that breaks the passive layer will corrode before the parent metal does. Anneal, do not engrave, on parts that live in salt. |
| Aluminium Capable | **Marking only.** Black anodised aluminium is the easiest material on this machine: short pulses ablate the dye and leave a clean white mark at 1 500 mm/s and low power, and it is the mark used on the acceptance coupon. Bare and mill-finish aluminium marks dark grey by oxide formation, but contrast is lower than on steel because aluminium reflects a good deal of 1064 nm and conducts away what it absorbs - expect to slow down and take more passes. Two cautions. Bare polished aluminium is a mirror at this wavelength and is a specular reflection hazard, which is what the beam dump plate is for. And it cannot be cut, at any thickness, at any setting. |
| Plastic Light duty | Only plastics that absorb at 1064 nm mark, which in practice means **pigmented or laser-additive polymers**: carbon-black-filled ABS, PA and PBT, and engineering polymers compounded with a laser additive, which foam or darken cleanly at 30 to 60 kHz and low power. Everything else does nothing useful. Natural PP, PE, POM and clear polymers are largely transparent at this wavelength, so the beam passes through the part and marks whatever is behind it - that is a containment hazard, not a failed setting. **PVC and PTFE are absolutely forbidden** - hydrogen chloride and chlorine from the first, hydrogen fluoride and perfluoroisobutylene from the second, both of which harm the operator and corrode the machine. The class is 'light' because the answer depends on the compound and not on the polymer name, and because a fibre marker is the wrong tool for plastic when a CO2 source exists. |
| Wood Light duty | Wood absorbs 1064 nm poorly. Dense dark hardwoods and thin ply will darken and shallowly char under long pulses at low speed, and the result is inconsistent across the grain because the resin content is inconsistent. Light woods, MDF and paper barely respond at all. This is a wavelength mismatch and not a power limit: organic material absorbs 10.6 micron CO2 radiation strongly and 1064 nm weakly, which is why wood engraving belongs on a CO2 platform. Additionally, this machine's enclosure is designed to contain metal fume and its extraction is filtered for particulate - charring wood inside it loads the carbon stage quickly and for no good reason. |
| Acrylic Not supported | Not supported, and the reason is a hazard rather than a poor result. **Clear and cast acrylic is transparent at 1064 nm.** The beam does not stop in the sheet: it passes straight through at close to full power and marks, ignites or reflects off whatever is behind it - the beam dump, the table, a fixture or a gap in a baffle - with no visible indication that anything is happening, because the wavelength is invisible. Pigmented dark acrylic will absorb and mark, but Roboda does not publish acrylic as a capability, because the difference between a sheet that stops the beam and one that passes it is not something an operator can see. Acrylic cutting and engraving is a CO2 job on a different Roboda platform. |
