change from tool 0 to tool 1

what code and were would i insert it to get the printer to go from tool 0 to tool 1 , so that the letters a are different color than the tag ?


pet_name="NAME"; //Your pet name
phone_number="000-0000000"; //Your phone number
bone_height = 5; //Tag height in mm
font_height=2; //Font height in mm


module t(t){
 translate([-1,(-len(t)*3.8),bone_height])
   rotate([0, 0, 90])
    linear_extrude(height = font_height)
      text(t, 10, $fn = 16);
}
module t2(t){
 translate([-1,(-len(t)*3.8),bone_height])
   rotate([0, 0, 90])
    linear_extrude(height = font_height)
      text(t, 7, $fn = 16);
}



//bone
//left side of bone
translate([-10,-30,0])
{
    translate([20,0,0]) cylinder(h=bone_height, r=14);
    cylinder(h=bone_height, r=14);
};
//right side of bone
translate([-10,30,0])
{
    translate([20,0,0]) cylinder(h=bone_height, r=14);
    cylinder(h=bone_height, r=14);
};
//center of bone
translate([-15,-25,0]) cube([30,50,bone_height]);
translate([0,-5,0])
t(pet_name);
translate([11,14,0]) t2(phone_number);

//tag attachment
difference(){
    translate([-16,0,0]) cylinder(r=6, h=bone_height);
    //prevents non-manifold
    translate([-16,0,-1]) cylinder(r=3, h=((bone_height)+2));
}

Somebody with more (more than zero!) experience with multiple extruders will probably provide more information, but I may be able to help a little right away...

OpenSCAD per se won't help you.  The models it produces don't have any color/material/tool marking.  (And, for STL, that's pretty much the way it is.)  There are some ideas being floated but they haven't been implemented.

What I believe you need to do is to generate *two* models, one for each material, and then recombine them in the slicer.

Probably you would have your OpenSCAD program run in one of three modes:  all parts (probably with preview coloring), the first material, and the second material.

If it's just a small number of prints, there's another option to just
keep the model as it is and define a manual filament swap pause in
the slicer at the height where the main plate ends. This works with a
single extruder by swapping filament at that point. I don't know if
it also allows for manual tool change by sending the appropriate
g-code.

Maybe there's also some specific slicer option to swap tools at some
given height, but I don't know any details as I never had a printer
with more than one extruder.

ciao,
