    Added linear-axis for guiding the cable - works reliably

    Ghost released this 2024-03-14 13:13:49 +00:00 | 5 commits to main since this release

    Extensively tested the newly added linear-axis for guiding the cable
    with 50m target length

    Major additions since last version:

    • Hardware:

      • Add stepper driver to cabinet
      • Change pin assignment
      • Add 100mm linear axis with stepper motor
      • Populate voltage divider for measureing supply voltage in pcb
      • Add filter pcb to denoise stepper signal

    • Firmware:

      • Add stepper driver
      • Customize driver significantly to add accel/decel limit, force to 0
        at direction change
      • Guide: Add algoritm to travel the guide left<->right depending on
        direction, measured cable length and already wound layers
      • Detect poweroff by monitoring the 12V supply voltage
      • Store last axis position in nvs at shutdown to optimize homing
      • Add readme, Add photo, Add modbus-tests, Add datasheets, Add
        schematic

    • CAD:

      • Add parts for mounting the axis
      • Create new Reel versions: Add interlocking counterpart, Make sturdier

    Known issues / Todo:
    - Make guide travel length variable (e.g. when winding 5m only there is no
    need to use the entire reel width)
    - Store last cable length at shutdown as well?
