What this machine will and will not work
| Wood Production | The material this head is best at. Engraves everything - ply, MDF, hardwood, bamboo, cork, card and leather - at a commanded 3 000 to 6 000 mm/min in a single raster pass, though on scan lines shorter than about 200 mm the axis spends most of the line accelerating and never reaches the top of that range. Cuts 3 mm poplar ply in one pass at 350 mm/min, 6 mm in three passes, and 9 mm slowly and badly with a charred kerf. Darker and denser timbers engrave with better contrast and cut worse. Air assist is mandatory: without it ply flames rather than cuts. Brush the ash out of the honeycomb tray between jobs, because accumulated debris is what actually catches fire. |
|---|---|
| Plastic Light duty | Honest answer: some plastics, not most. Dark and opaque ABS, HDPE and painted polystyrene sheet mark and engrave well, and opaque 3 mm sheet cuts in two to three passes with a melted rather than a polished edge. **Natural, clear and light-coloured plastics do not work at all** - 450 nm passes straight through them and the beam lands on whatever is underneath. Polypropylene and nylon melt and string. PVC and PTFE are forbidden outright, and polycarbonate chars instead of cutting. 'Light' is the honest class because the list of plastics this head handles well is shorter than the list it does not. |
| Acrylic Light duty | Opaque and dark cast acrylic only. Black, dark blue and other strongly pigmented cast sheet cuts at 3 mm in two passes with a matt edge, and engraves crisply. **Clear, translucent and light-tinted acrylic cannot be cut or engraved by a 450 nm diode at all** - the material is effectively transparent at this wavelength, the beam goes through it, and the only thing that gets marked is the honeycomb tray. That is a wavelength limit, not a power limit, and no settings change it: clear acrylic is CO2 work and this platform has no CO2 variant. Extraction is mandatory - lasered acrylic gives off methyl methacrylate vapour. |
| Aluminium Light duty | Surface marking on **anodised or powder-coated** aluminium only, by ablating the dye or the coating to expose the metal underneath. That produces a permanent, high contrast mark for panels, tags and instrument fronts, and it is a genuine capability. **Bare aluminium is not marked, not engraved and not cut.** At 450 nm bare aluminium reflects most of the beam, and 20 W optical over a 0.06 mm spot cannot reach its melting point - it also throws that reflection somewhere nobody has assessed, which is why polished metal is forbidden under the beam. No marking spray is supplied and none is claimed. |
| Steel Not supported | This head cannot cut, engrave or mark steel, and Roboda will not claim it can. Cutting steel by laser needs a kilowatt-class source with an oxygen or nitrogen assist; 20 W is three orders of magnitude short. Marking steel needs a source the metal actually absorbs and a pulse energy that melts a surface layer - in practice a 1064 nm fibre laser - and a 450 nm diode reflects off bare steel and reaches nothing like the required intensity. Steel marking in the K-Series exists only on the enclosed fibre variant of the professional platform, and steel cutting only on the plasma variants of the large-format platforms. Neither is this machine. |
| Mild steel Not supported | Mild steel is refused for the same physics as steel, and refused twice over on this platform. A 20 W 450 nm diode does not couple into it, does not melt it and does not mark it; putting mill-finish mild steel under the beam produces a bright specular reflection out of the machine and nothing on the workpiece. Painted or powder-coated mild steel can have its **coating** ablated, which is coating removal and is described under aluminium, not steel marking - Roboda does not present it as one. Cutting mild steel sheet in the K-Series is a plasma-head job on the large-format platforms only. |
