  • updated firmware to latest version of laos. To do this had to switch around X and Z axis in LAOS code, and compile manually. We did this mainly through following the instructions @ GitHub - LaosLaser/Firmware: Embedded software (firmware) for the laser system and components, including configuration files, but had to adjust parts of the mbed ethernet stack to allow it to compile.

  • changed timeout of extraction in config to 120s from 30s after the last movement has happened

  • tested and updated version of visicut on the visual arts mac to 1.9-70. This is the latest version that works consistently, with newer versions refusing to cut on non-complex files. @thinkl33t to raise an upstream issue with our findings.

  • set to in service

  • Replacement strut fitted on lid RHS
    • New strut mount wasn’t aligned with pre-drilled holes so they have been drilled to widen them and the mount is installed with some bolts and nuts
  • Seems stable but would advise caution for the moment
    • Don’t leave your head unattended within the vicinity of the open lid :upside_down_face:
