November 08, 2018

Kitronik offers DXF files for making a baby-baby grand case for your Klef Piano.  Kitronik tutorial is found here Klef DXF Files  Timelapse Video of Build.     The Elmwood Glowforge only takes SVG & PNG files.  To get started I imported the DXF file for "Kitronik_Perspex+Wood_Piano" into Inkscape and separated the layers to be laser cut into a SVG file and copied the layers to be embossed/engraved into a separate PNG document.      Links for both are below.Since every laser cutter is different, you mileage may vary.  Laser Cut SVG Piano Template Engraved PNG Piano Template With the two documents uploaded to the Glowforge, I noticed the scaling was slightly too small from the DXF > SVG conversion.
