Here’s a fun quick hack from [Timo Birnschein] about using the 3D laser engraving (or ‘stamp’ engraving) mode of certain laser cutter toolchains to create a handy countersink shape in …read more Continue reading Quick Hacks: Countersinking Screw Heads With 3D Laser Engraving
Expensive laser cutters have a 3D engraving mode that varies the laser power as it is etching a design, to create a 3D effect. [Benjamin Alderson] figured this could be replicated on a cheap Chinese laser — so he made his own program called SmoothCarve.
He’s got one of those extra cheap blue-box 40W CO2 lasers you can nab off eBay for around $600-$800, but he’s replaced the control board with a SmoothieBoard as an easy upgrade.
