Error: Duplicate lpart id's

[mbugert]

Hi Ken,

the library requires each lpart to have a unique name so that it can identify them during the arrangement process later on. You define an lpart named pad and instantiate it three times, therefore it returns Error: Duplicate lpart id's: pad.

A quick fix would be to include the diameter in the lpart names, i.e. by writing lpart(str("pad", diam), [diam, diam]) and lpart(str("pad_with_hole", odiam, idiam), [odiam, odiam]).

If you need multiple pads of the same diameter, this will fail for the same reason as before of course. You could then do the following:

include <laserscad.scad>

kerf = 0.5;
thickness = 3;
$fn = 200;
font_color = "black";
font_size = 1.5;

module pad(diam, id="") {
    lpart(str("pad", diam, id), [diam, diam]) {
        lengrave(thickness, true){
            color(font_color)
            text(font="DejaVu Sans", size=font_size, str(diam),
            halign="center", valign="center");
        }
        cylinder(h=thickness, d=diam + kerf);
    }
}

for (x=[1:4], y=[1:4]) {
    translate([x*10,y*10,0])
        pad(8, id=str(x,y));
}

Many thanks. I thought that every lpart _type_ needed a unique name. You’re telling me that each lpart _instance_ needs a unique name. I’ll get back on it. Many thanks, Ken ******************************* Kenneth R. Beesley, D.Phil. PO Box 540475 North Salt Lake UT 84054 USA

Yeah, I agree that it's not particularly obvious from the readme. I'll update that.

I’ll get back on it.

👍👍

Hello Michael, Thanks for the updates and messages. When I run your code sample (from the message below) or my own code, with the modifications that you describe, I get the following ValueError message: beesley$ make cut model=/Users/beesley/perso/shop/3D/openscad/projects/pads/pads-bugert.scad Getting object bounding boxes...
