    type in 50 and press enter, then create the line
    do not type the '%' sign on the end of the number

    a centerline is any line not connected to other stuff.
    you cannot set a cut property on just one segment of a polyline, so the fold tool does a little adjustment...
    a fold line is a line you drew across a shape where you want a hinge to fold. then you click it with fold tool selected and it will automatically disconnect both ends from the parent shape by a little bit, and make it a centerline cut.
    try it and see, draw a line across the middle of a rectangle and centerline it, all the lines turn green.
    draw the same figure and fold cut the line and only the line turns green and if you zoom in you will see that the ends are just short of the bounding rectangle.

    ok...I'm an idiot. Hitting return does the trick (I didn't actually type '%') It's amazing that you have the patience to deal with such nube questions. Thanks.

    I don't have patience, but I pretend pretty good :)
    Just about every question either already been answered in the help or online. The trick is asking google the right question <-:

    Exact stop, Constant speed (G61 , G64)
    For a continuous and smooth cutting, i suggest editing PhlatMill.rb
    (...\Plugins\Phlatboyz\PhlatMill.rb)

    In the line of code:
    stop_code = Use_exact_path ? "G61" : "" # G61 - Exact Path Mode

    put:
    stop_code = Use_exact_path ? "G64" : "G64" # G61 - Exact Path Mode

    1 - there is an option in MyConstants.rb to turn off outputting G61
    by turning the output off, you get to choose what mode your controller lives in. This is because G64/G61 are modal, once set, whichever is set will stay set until the other one is set, and some controllers, like LinuxCNC, will remember it between reboots too.​
    2 - before using G64 please read the manual for your controller to find out exactly what it is going to do. Results can be quite unexpected, especially at high speed on acute corners.

    3 - some controllers support parameters for G64, like 'G21 G64 P1' would set 1mm as an allowable offset in constant speed mode, which means a corner might be rounded off by that much. Without the parameter you don't know how much it is going to round off, might be quite a lot. I have found P0.25 (mm) to be good on a hot wire cutter to prevent segmentation lines on the surface of the foam.

    Grateful for the indication

    For most of our machines with stepper motor and low speed, G64 is more interesting, is an option that meets the majority of cases, cutting is faster and smoother, I suggest you try.
    In specific cases which need to be accurately G61, leave as it was.

    this actually needs to be made into a 3 way option
    output G61
    output G64
    output neither

    meanwhile, for a simpler option
    change
    stop_code = Use_exact_path ? "G61" : ""
    to
    stop_code = Use_exact_path ? "G61" : "G64"

    This means that if Use_exact_path is true it outputs G61, if false it puts G64. as always, every user must do the research and make sure their controller actually knows what to do with this code, and experiment on scrap to see what it does. for example GRBL will not like G64 in the code at all.

    I understand, and saw, what G61 does but I'm not sure what G64 will do and how it compares to have no code at all. Neither G61 nor G64, which is what I do normally.

    controllers which do not support G61/G64 are always in G61 - ie they always go to the programmed position exactly.
    controllers which support these codes, must be in one of the modes, and they will generally remember the last one used which is why G61 can be added to Sketchucam output, for tabs and slots to fit, you need absolute stop mode.

    Hello, may I know if SketchUcam can generate G-code and be save as a gcode file instead of a cnc file?

    sure it can, just type the name that you want and it will save it with that name.extension.
    OR
    set (in the MyConstants.rb file, see the help for how to create it)
    Code:
    Default_file_name = "gcode_out.nc"
    Default_file_ext = ".nc"
    
    to whatever you need the extension to be and next time you start Sketchup, that is what it will use when you output Gcode in the future.

    FWIW, I just installed v1.2 into SU8pro (with the "old" Phlatscript in it), and I did not have an "install extension" prompt in the window/preferences/etc. menu. So I tried the SU7 install method (by renaming the .rb to .zip and then move the unpacked contents to the plugins folder, and it works like a champ!

    Thank you all for your hard work!!!
    The Phlatprinter2 is (although not used that much nowadays) still going strong! And every time I do use it once in a while, I am still amazed and enchanted by the works of the machine!

    there were various versions of Sk8, and older ones do not have the extensions install button.

    Do we have SketchUp 2015 compatibility? I've about had it with SketchUp 2014. It has more bug splats than my windshield in the summer.
