What this machine will and will not work
| Wood Production | A production material and half of what this machine will be bought for. Poplar and birch ply, MDF, balsa, veneer, card, paper, cork and thin hardwood all cut and engrave. Working figures against a 100 W measured output with air assist: 3 mm poplar ply cuts in one pass at about 1 100 mm/min, 6 mm at 450 mm/min, 12 mm at 150 mm/min in one pass or two passes at 320 mm/min for a squarer edge; raster engraving runs at 6 000 mm/min at 18 percent power. MDF cuts but leaves a dark charred edge that no setting removes - that is the 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 the polymer and not on the word. Delrin and polypropylene cut cleanly. HDPE and polyethylene cut but melt a rounded edge because the material carries heat away faster than the beam delivers it. Polyester film, rubber and cork behave well; ABS melts, stinks and leaves a tacky edge and is not recommended. **PVC and PTFE are absolutely forbidden** - hydrogen chloride and hydrogen fluoride respectively, which harm the operator and corrode the rails, the rack and the fan. **Polycarbonate is forbidden as a cutting material** even though it is used as the shield panel: it absorbs 10.6 micron strongly at the surface, so it chars, flames and yellows instead of cutting - excellent as a barrier, useless as a workpiece. |
| Acrylic Production | The material a CO2 laser is best at, and the only Roboda platform that can do it at this size. Cast acrylic cuts with a flame-polished edge straight off the machine - no secondary finishing at all - because acrylic absorbs 10.6 micron completely at the surface and vaporises rather than melting. Working figures at a measured 100 W: 3 mm at about 1 400 mm/min, 6 mm at 600 mm/min, 10 mm at 260 mm/min, all in one pass with air assist at low pressure. Extruded acrylic cuts but the edge comes out matt rather than polished, which is the sheet and not the machine. Acrylic burns readily and gives off methyl methacrylate vapour: extraction on, and stay with the machine. |
| Aluminium Not supported | Not supported, and there is no setting that changes it. Bare aluminium reflects the large majority of a 10.6 micron beam and conducts away what it absorbs, so 100 W raises no melt pool at any feed. Worse than useless, it is actively dangerous: a polished aluminium sheet on the bed returns a specular reflection out of the machine's designed beam path, which is precisely the hazard the roof panels and the eyewear exist for. **Do not put polished metal sheet on this bed.** Anodised and powder-coated aluminium can have its coating ablated to expose the metal underneath; that is coating removal and Roboda does not publish it as a metal capability, because it tells you nothing about what the machine can do to metal. |
| Steel Not supported | Not supported. Cutting steel with 10.6 micron light is done at kilowatt class with an oxygen assist jet doing much of the work; marking steel is done at 1 064 nm, which the metal actually absorbs. A 100 W CO2 beam on steel produces a warm spot and a reflection. Steel and stainless cutting on a Roboda platform is the plasma head on this same machine - RBK-L1-P - where the tool is a transferred arc; steel marking is the fibre head on RBK-E1. Neither of those is this variant. |
| Mild steel Not supported | Not supported, for the same physics as steel, plus a trap worth naming. Hot-rolled mild steel carries mill scale, which absorbs 10.6 micron far better than the metal does and will glow convincingly under the beam. That is the scale heating, not the metal being marked, and it wipes off. Mild steel cutting on this platform is available - on the plasma variant, and only there. The laser kit does not cut mild steel. |
