What this machine will and will not work
| Wood Production | A production material and half the reason to buy this variant. Poplar and birch ply, MDF, balsa, veneer, card, paper, cork and untreated hardwood all absorb 10.6 microns strongly and cut cleanly. Working figures at the machine's measured output with air assist and extraction running: **3 mm poplar ply one pass at about 1 200 mm/min, 6 mm at about 500 mm/min, 9 mm at about 250 mm/min**, and 12 mm is the practical limit at about 120 mm/min with a dark edge that no setting removes. Raster engraving runs at **4 000 mm/min at 15 % power, and that ceiling is the machine and not the source**: the X ballscrew whips at 831 rpm, 665 rpm derated, and 4 000 mm/min on a 10 mm lead is the 400 rpm this platform is built around. A belt-driven laser rasters three times faster and it is honest to say so rather than to quote its number here. MDF cuts but always chars a brown edge - that is the urea resin burning, not a tuning problem. Every one of these cuts is a fire in miniature: air assist on, extraction on, operator in the room. |
|---|---|
| Plastic Capable | Capable rather than production, because which plastic works depends on chemistry rather than on the word 'plastic'. Delrin, HDPE, polypropylene and rubber sheet cut, but they melt a rounded edge rather than a square one because they carry heat away faster than the beam delivers it, and polypropylene in particular wants a fast feed and a large nozzle. Foam board, cast nylon and natural leather cut well. **Absolutely forbidden: PVC** - vinyl, faux leather, banner material, foam PVC board - because it releases hydrogen chloride that harms the operator and corrodes the rails, screws and mirrors; **PTFE**, which releases hydrogen fluoride; **ABS**, which melts, gums the nozzle and gives off hydrogen cyanide; and **polycarbonate**, which absorbs 10.6 microns so completely that it chars and burns instead of cutting. That last one confuses people, because polycarbonate is exactly the right material for the enclosure glazing on this machine - for the same reason it is the wrong material to put under the beam. |
| Acrylic Production | **The material a CO2 laser exists for, and the difference between this variant and a diode machine is total.** Acrylic absorbs 10.6 microns completely whatever its colour, so clear cast sheet cuts as readily as black - a blue diode simply passes through clear acrylic and does nothing. Cast acrylic cuts with a **flame-polished edge straight off the machine**, which needs no finishing at all: 3 mm at about 1 500 mm/min, 5 mm at about 700 mm/min, 10 mm at about 250 mm/min, with 12 mm the practical limit at about 150 mm/min. Sign work, display work, light boxes and full 1 200 mm sheets are production jobs here. Extruded acrylic cuts but gives a frosted rather than polished edge. Acrylic burns readily and gives off methyl methacrylate vapour: extraction on, air assist on, and stay with the machine. |
| Aluminium Not supported | Not supported, and there is no setting that changes it. Bare aluminium reflects more than 96 % of a 10.6 micron beam and conducts away most of the rest, so 80 W raises no melt pool at any feed. Worse than useless, it is actively dangerous: a specular reflection off a polished aluminium surface leaves the designed beam path entirely and can find the lens, the enclosure seal or the operator. Anodised and powder-coated aluminium will have its coating ablated to expose the metal underneath, which is coating removal rather than a metal capability, and Roboda does not publish it as one - it tells a buyer nothing about what the machine can do to metal. Aluminium machining on this platform is the spindle: the S and SL variants. |
| Steel Not supported | Not supported. Cutting steel with light needs a kilowatt-class source plus an oxygen or nitrogen assist jet at several bar through a precision nozzle; marking steel needs a 1 064 nm fibre source, because that is the wavelength steel actually absorbs. An 80 W CO2 tube at 10.6 microns delivers neither, and on bare steel it produces a warm spot and a reflection. Steel marking on a Roboda platform is the fibre head on RBK-E1; steel cutting is a plasma head on the large-format platforms. Neither of those is this machine, and no amount of passes turns one into the other. |
| Mild steel Not supported | Not supported, for the same physics as steel plus one trap worth naming. Hot-rolled mild steel carries an abrasive mill scale, and scale is an oxide that absorbs 10.6 microns far better than the metal under it - so it will glow convincingly under the beam and give every impression that something is happening. It is the scale heating, not the metal marking, and it wipes off with a rag. Neither cutting nor marking mild steel is a capability of this head and neither is published as one. |
