Drawing patterns on cork with the laser cutter.
I recently got into making espresso at home. As part of that I had an old cork mat that I wanted to use to store some of the paraphernalia on. The mat that I wanted to use had a burn mark in the middle but that sanded out quite easily and left a nice smooth surface.
I did a quick image search for “Coffee flower svg” and found an image that I liked then imported that into inkscape. Setting up the paper size in inscape to match the mat size allowed me to scale it to the right size. I converted the image into a path and ungrouped it so I could remove some text. Saved it. Then loaded it into K40. All pretty quick.
I’m happy with the result and will probably play with cork again. Bonded cork like this is made by just squeezing the cork in a high temperature environment so there should be no glue to gas off just wood fumes.
Using the hackspace laser cutter I went with 2.5mA and 100mm/s raster engrave. It took about 45mins. It cut a little deep so I would go with at least 150mm/s next time ( as per the wiki instructions! Doh! ).
