    Oh... I get you...

    No, I am using the cube3_decoder executable in Windows 7.
    It's a fairly straight forward cut and paste

    To be clear, the CAD images are Creo Parametric (what was once Pro|Engineer).
    The slicer file is a .cube3 from the Cube3 application in Windows 7.

    save the cube3 file from the Default Cube3 app.
    drop the file on the executable
    notepad makes quick work of the image characters below the last M107 command in the generated .bfb file
    import the .bfb into Excel as text/space delimited/data type text
    filter column A with "G1"
    highlight columns B,C,&D ctrl-C; then paste that into notepad
    in notepad, replace all characters X, Y, and then Z with nothing
    optionally remove the purge point locations at the start (2) and the end (8?) of the file
    save the file as a .pts file
    import the .pts file into Creo CAD and do magic with the numbers

    Anyway, yes, I am using what I have at hand to analyze the 3D Systems slicer.
    The release of this simple decoder allowed me to do this, finally!

    This method can be used for gathering any point cloud.
    The software in which you want to use it will have a specific format.
    The method described above will yield a space delimited series of X, Y, and Z values in Ascii.

    Cracked another code in the Cube App slicer...

    Design element for designers:
    WELL BONDED PERMIMETER WALLS FOR FLAT OBJECTS

    If you want a first-layer trace-only but a solid face following, try the following in your design;
    Make your trace width 1.68mm (1.7). This creates a 4-wide trace that fuses reasonably well because the center two traces are stuffed between the first two.
    For the most part, it looks like only 3 traces
    Make this first trace layer 0.20mm deep.
    Somehow the layer thickness of "200um" is actually 0.1975mm so it counts for a complete layer.

    The next layer surprised me. Now that I have 4 traces lain, the second layer runs 2 traces along the perimeter.
    So I have two traces to "stick" the solid layer to... and you'd think... or hope it would just draw all the way across the part.
    But no, it stops at the details within the first layer.
    This is not a problem as inner traces on the first layer are also 1.68mm wide and therefore the solid print on the second layer has a shelf to tack onto.
    Talk about GAP! But there is a reason for this. A couple as a matter of fact.

    Do you hate printing thing with large surfaces because they always curl on you, or you feel you need sidewalks?
    Or the opposite of not being able to release the print from LokBuild when there is a large flat area attached?


    I do need to add one thing I noted quickly; your export precision settings do matter.
    If any physical width in the print goes to 1.5mm anywhere (tested down to 1.6mm width), the trace count reduces from 4 to 2.

    Another design tip is when infill starts.
    I need to confirm this, but infill can be avoided if you stay under 7 layers.
    For some reason, it always lays 4 layers on the build plate, and it finishes up with 3 layer on the top surface.
    This is a nice design tip to keep in mind.
    Remember, 0.1975*7=1.3825mm ...or there about will make for a solid print.
    The actual print will come out to around 1.5mm when you run a generous gap as I do.

    Ha! Put up or shut up, right?

    One thing that occurred to me is that this method of recessing a face would help with ABS.
    Done, yes it helps with all the usual caveats.

    LokBuild with glue using 3D Solutech Joy-Pack ABS White:

    I've been lucky on my other LokBuild sheets but this one's been stubborn.
    Repurposed glue to always have glue on the plate; just add water and let dry ... well, sort of.
    This plate also has a 6" square moat around it :|


    No elephant foot on the 1st layers; no curling (feel the need to knock on wood!).

    ABSvane_2.PNG
    Just saying that curl avoidance doesn't mean stuffing your print into the build plate.


    The treatment is the same as PLA. All the stringy lines -are- attached

    ABSvane_3.PNG

    This kind of treatment could be used on larger rectangular surfaces to relieve some of the thermal stress.
    A kind of millennial wicker

    Not to mention much easier removal of the print from the build plate!

    4 out of 5 for 3D Solutech ABS joy-pack refills have been excellent!
    Actually, if you wanted to find them, they are Joy-Packs on Amazon.
    https://www.amazon.com/s/ref=sr_nr_p...rnid=126834011
    (not spamming.... just sharing!)

    I've got a question into them to find out if the formulation is any different from their 1.75mm reels.

    - - - - - - - - - -

    Time to put a caveat on the previous posts...
    Learned something new though.

    Ever notice that the infill on the first layer is sometimes pulled far away from the first 2 outer traces?
    There is a reason, and it affects the above posts.

    Quick narrative is that straight walls (upward) along the side (Z) will follow the rules and guidelines outlined above.

    If the part has a taper inward right from the get-go, the above method of "stick relief" or "texturizing" won't work.
    When it comes to the second layer, the offset inward of the fill traces do not get staked to the first 4 traces created by the first layer.
    This will require more experiments to understand the slicer's behavior.

    If you are following where this discussion has been going, this will make more sense.
    But if you find yourself some day needing this information, of course I will clarify if I can.

    that last piece looks a bit familiar!

    ... you don't have to count the layers, Todd. This one is based on .16" thickness.
