What this machine will and will not work
| Wood Production | A production material for this head and the reason most of these machines are bought. Working figures against a 60 W measured output with air assist on: 3 mm poplar ply cuts in one pass at about 840 mm/min, 6 mm ply in one pass at 300 mm/min, 9 mm ply in two passes, and raster engraving runs at 4 000 mm/min at 15-20 % power. MDF cuts to 6 mm but leaves a dark charred edge that no setting removes - that is the glue burning, not a tuning problem. The 900 x 600 bed takes a full 3 x 2 ft panel, so this is genuinely a panel machine rather than a sample cutter. Every one of these cuts is a small fire: air assist on, extraction on, operator in the room. |
|---|---|
| Plastic Capable | Broad but conditional, which is why the class is 'capable' rather than 'production'. Delrin, HDPE, polypropylene and PET cut and engrave, though the thermoplastics leave a rounded rather than a square edge because they melt ahead of the kerf; rubber, polyester felt, cork and leather board cut cleanly. **PVC and PTFE are absolutely forbidden** - hydrogen chloride and hydrogen fluoride respectively, which harm the operator and corrode the machine's rails and screws. **Polycarbonate is forbidden too**: it absorbs 10.6 micron at the surface, so it chars, yellows and catches fire instead of cutting. ABS is forbidden for hydrogen cyanide. The rule is that the material must be identified before it goes on the bed, not after. |
| Acrylic Production | This is the material CO2 was made for, and the difference from a diode source is not marginal. **Clear, coloured, cast and extruded acrylic all absorb 10.6 micron completely**, so there is no pigment requirement and no sheet that quietly passes the beam. Cast acrylic gives a **flame-polished edge straight off the machine** - no sanding, no buffing - which is a finish neither the router head on this platform nor any diode source can produce. Working figures at 60 W with air assist: 3 mm cast in one pass at about 900 mm/min, 6 mm at 360 mm/min, and 10 mm in one slow pass at about 120 mm/min, which is this head's honest ceiling. Extruded sheet cuts as well but the edge comes out matt. Acrylic burns readily and gives off methyl methacrylate vapour - extraction on, and stay with the machine. |
| Aluminium Not supported | Not supported. Bare aluminium reflects most of a 10.6 micron beam and conducts away what it absorbs, and 60 W raises no melt pool at any feed. Worse, that reflection is specular and invisible: a polished aluminium offcut left on the bed is the single most dangerous thing that can be in this machine, because it sends the full beam somewhere the enclosure was not designed to contain. Anodised and powder-coated aluminium can have its **coating** ablated to expose the metal underneath, which is coating removal and not a metal capability - Roboda does not publish it as one, because it tells you nothing about what the machine can do to metal. Aluminium milling on this platform is the S and SL variants with the spindle head. |
| Steel Not supported | Not supported, and no setting changes it. Cutting steel with light needs a kilowatt-class source plus an oxygen or nitrogen assist jet delivered through a high-pressure nozzle; marking steel needs a 1 064 nm fibre source, because that is a wavelength steel actually absorbs. A 60 W CO2 tube at 10.6 micron delivers neither - on bare steel it produces a warm spot and a reflection. Steel marking on a Roboda platform is the fibre head on RBK-E1, and steel cutting is a plasma head on the large-format platforms. Neither is this machine and neither is offered as an upgrade to it. |
| Mild steel Not supported | Not supported, for the same physics as steel. Hot-rolled mild steel additionally carries an absorbing mill scale that will glow convincingly under the beam and give the impression that something is happening - that is the scale heating, not the metal being marked, 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. |
