#self-replicating #Maslow #2d-cutting #CNC with a gallery of open furniture designs
on 02023-12-27Opendesk is a #2d-cutting design exchange website (by the company Fabbed, which runs FabHub.io) with many open-source #furniture designs to #CNC route out of (mostly) 18mm Baltic birch plywood. Furniture makers listed on the site (who can thus submit quotes in response to enquiries from clients) pay a 38% markup: 8% for the designer, 30% for Opendesk. Currently they have 37 designs by 15 designers, and over 48 makers (“digital fabricators”) listed (probably around 100), including Pioppo Carpintería here in Buenos Aires, something like a dozen in France, 15 in England. tav's project
on 02016-10-14#video of the #Maslow #CNC #2d-cutting router for 4×8 plywood, basically a #hanging-plotter using #25 roller chain on a 200:1-reduced DC motor with a relatively coarse shaft encoder on the motor side of the gearbox, with a couple of bricks weighting down the router. 8148 steps/rev encoder, ± 1/64th inch (.4 mm) or better, 48 inches/minute. Not all open source, but all at least cc-by-nc-sa. By BarSmith, aka BarbourSmith. US$350, not including the router or bricks.

on 02015-11-30Explains that in #laser-cutter design for finger joint #manufacturing, you might want to curve the finger (“tooth”) edges a bit to allow for the kerf. No numbers on how far to curve, unfortunately. Does have Ponoko cost numbers from 2008, and mentions that approximating curves with lines “reduces cutting costs significantly”. #2d-cutting
on 02015-11-30Thomas Oster’s bachelor’s #pdf #dissertation on the VisiCut #laser-cutter software. Mentions he got about an inch per second (25 mm/s) at 500dpi out of the Epilog Zing cutter he was using, or 8 inches per second with the laser off, and documents the HP-PCL, PJL, HPGL, and LPD interface of the machine in some detail. #2d-cutting
