  • Build Notes for Clank-LZ

    this page occasionally loads slowly

    The CAD

    final

    Clank was developed in Fusion 360. The most recent .f3z (Fusion 360 Archive) and .step files are available in the CAD folder in this repo. These files have enough hardware included that one should be able to figure out which bolts / etc go where, but are not complete (i.e. in a group of four bolts, three may be missing).

    the latest step file
    the latest rhino file (thanks Zain!)

    The BOM

    A Bill of Materials for the lz machine is available in this spreadsheet. Most parts can be sourced from McMaster, DigiKey or Amazon (in the US). Other vendors include SDP-SI and Stepper-Online.

    Hardware totals to around $400 USD for the machine.

    Controllers used here cost about $250 USD.

    The Controller

    Our versions of Clank use experimental controllers that aren't available publicly, but the machine could easily be configured for use with any off-the-shelf GCode interpreter.

    Final Checklist

    Before you turn your machine on, please do these checks:

    • The spindle and spindle motor are well connected: try holding the spindle motor stationary while turning the tool holder (the bottom part of the spindle)
    • Earth, Neutral and Line connections between the power supply and the wall voltage are correct (there are E/N/L labels on the fuse module, double check)
    • PSU is set to 115v, not 220v. There is a slide switch on the side of the PSU.
    • Your 10-pin IDC cable is oriented correctly: see the wiring video to check.
    • The small Black & Green cable from the 20A ESC to the ESC Breakout Board is plugged in with the Black side on the left.
    • The motor boards are appropriately mounted: YL on the Y Left, X on the X, etc.

    To power up:

    • always plug the USB logic in first, before switching the PSU on.
    • when you plug the USB in to your computer, there should be at least one LED turned on at each of the 6 boards. if this isnt' the case, something is wrong
    • if they are all on, you should be OK to boot the controller and mill some things

    Print Settings

    Most parts not-on-the-bom for these machines are 3D Printed: exceptions are the Motor Plates (which can be printed, if you'd like) which we mill in Phenolic (to prevent softening against warm motors), and the Bed which is milled from a sheet of HDPE.

    Printing parts should work with most settings: definitely larger infills and higher perimeter counts than standard settings will make better machines. These are what I use:

    In either Prusa Slic3r, or Slic3r itself:

    • 0.4mm nozzle
    • 0.2mm layer height
    • 'expert settings' (top right) / layers & perimiters / check 'external perimeters first'
    • layers & perimeters / perimeters: 5
    • layers & perimeters / horizontal shells: top: 6, bottom: 6
    • infill, either:
      • 100%, rectilinear
      • 40-60%, grid or line
      • both: combine infill every: 2 layers

    Total Print Times & Weights

    These are rough notes from an early prototype, not exact, but very close.
