Medlemsmøte 2022-06-07: Free Software for Fabrication

Norwegian Unix User Group (NUUG) inviterer til medlemsmøte.

Tid:

Tirsdag 7. juni 2022 kl 18:30

Sted:

Møterom Kim, Rebel (Teknologihuset 2.0), Universitetsgata 2, Oslo.

Møterom Kim er opp trappen til andre etasje, sving til venstre, og gå LANGT bortover gangen.

Møtet vil også bli direktesendt over internett, samt direkte på <https://frikanalen.no/>. For mer informasjon se <https://wiki.nuug.no/grupper/video/streaming> om NUUGs direktesendinger.

NUUG inviterer medlemmer og andre interesserte til faglig foredrag med påfølgende diskusjon. Arrangementet er gratis.

Månedens tema er: «Free Software for Fabrication» med Sebastian Kuzminsky. Foredraget vil foregå på engelsk. Kort om presentasjonen:

Fabrication machinery such as 3D printers and CNC mills & lathes have become relatively inexpensive and accessible to hobbyists and groups like schools and hack spaces. This presentation outlines the software stack needed to make use of these machines, the interfaces between the layers, and the current state of some of the free software projects in this space.

Modern automated fabrication technologies take a drawing or model of a part and produce a physical copy of that part. Fabrication technologies can be divided into two broad categories: additive and subtractive. Additive machines (3D printers) build the part up from nothing, by adding material to shape the part. Subtractive machines (mills, lathes, laser cutters, etc) start with a chunk of raw material and remove everything that's not included in the part.

A human makes a model of the part they want using a Computer Aided Design (CAD) program such as FreeCAD, SolveSpace, OpenSCAD, Blender, or Inkscape. The data file describing the part is processed with Computer Aided Manufacturing (CAM) software such as FreeCAD, PyCAM, Cura, or Slic3r to generate machine-specific instructions for physically fabricating the part. Finally, the CAM instructions are fed to machine control software such as LinuxCNC, Machinekit, RepRap, or Klipper, which drives a machine to produce the part.

This presentation will demo robust, capable free software implementations of all three of these layers.

Sebastian Kuzminsky is a software engineer with an interest in free software and personal fabrication technology. He has been working with Linux computers that do stuff in the real world since the 1990s. He is an active developer on the LinuxCNC project. When not coding he like to play Go and run.

Alle medlemmer og ikke-medlemmer er velkomne. Vurdér også å melde deg inn i NUUG slik at vi kan arrangere enda flere spennende foredrag.

Vi minner forøvrig om NUUGs IRC-kanal #nuug på irc.oftc.net, epostlisten aktive@nuug.no for diskusjon om aktiviteten i NUUG og at NUUGs kalender er tilgjengelig på iCalender-format via <https://www.nuug.no/adict/ical.php?organizer=NUUG>.

Vel møtt!
