Greetings all;
I have composed this script to cap the output side of a harmonic drive:
But the bearing module is totally ignored. As seperate code elsewhere in
this drive it works great.
// new output disk to contain 62 tooth spline
// and incorporate for space savings the output shaft bearings
// and a timing belt pulley for output coupling.
// turn upside down to print so no supports needed
// will superglue timing pulley in center hole, and make bearing race
// addition later after verifying fit.
IDofspl=67.64;// to fit OD of 60 or 62 tooth spline
splsocht=6.00;// height of cup for spline
ODofCup=IDofspl+splsocht*2;// incorporate bearing in space
echo(11,ODofCup);
bb=4.36;// crosman bb dia plus clearance
//instclr=.4100;
// need some data for rotate_extrude
ctr_ht=splsocht/2;// center bb groove vertically
innr=ODofCup-splsocht/2;// get radius of bb groove
bbofs=splsocht/2;// might be useful
$fn=360;
translate([0,0,splsocht/2])
difference() {
// builds inner|outer walls of splined ring socket
cylinder(h=splsocht,d=ODofCup,center=true);// outer
cylinder(h=splsocht+1,d=IDofspl,center=true);//inner,1st subtract
bearing();
};// ends difference from line 20
// now cap it, this works! turn upside down to render
translate([0,0,splsocht+1.5]) // looks good
difference() {
cylinder(h=splsocht/2,d=ODofCup,center=true);// make hole in center
cylinder(h=splsocht,d=20,center=true);
};
// this code generates a [( )] shape for a ball bearing race pair in
// another file
module bearing() {
rotate_extrude()
translate([ODofCup,0,-10]) // below main gfx so can see
difference()
{
square(splsocht, center = true);
circle(d=bb);
square([.32splsocht, 1.1splsocht],center=true);
}
};
With that -10 in the translate I should see it below the main image and
could adjust it up into the difference, but no hits, no reported errors,
its just not there.
Once I can see it as a seperate item, the difference s/b become a union,
and the first square removed to get the shape for the 2nd removal in the
top difference chain.
I've been a day and a half now playing all those monkeys writing
shakespear, what am I doing wrong?
Thanks all.
Cheers, Gene Heskett

The # modifier is your friend. Put a # in front of the call to
bearing() and the problem will become mostly obvious.
In bearing(), you've translated the 2D object out to x=ODofCup. But
ODofCup is presumably the diameter, and when you translate something
out X and then rotationally extrude it, the translation is the radius.

Thanks, I didn't know that trick. The cheat page shows it

Everything in the Cheat Sheet is underscored.
That cheat sheet is one VERY handy thing. Whenever you have some time,
it's worth browsing it.
Right up there with the # is !, %, and *, which are worth a look.
Of particular interest (to me, at least), is the %. It may not seem
very useful at first glance, but it's handy to use for positioning
things like motors, components, screws, etc. that you want to visualize
but not render.

You are mixing 2D and 3D operations.
Make this change to bearing:
module bearing() {
translate([0,0,-10]) // below main gfx so can see THIS IS A 3D TRANSLATION
rotate_extrude()
translate([ODofCup,0]) // below main gfx so can see THIS IS A 2D
TRANSLATION

Greetings all;
I have composed this script to cap the output side of a harmonic
drive: But the bearing module is totally ignored. As seperate code
elsewhere in this drive it works great.
// new output disk to contain 62 tooth spline
// and incorporate for space savings the output shaft bearings
// and a timing belt pulley for output coupling.
// turn upside down to print so no supports needed
// will superglue timing pulley in center hole, and make bearing
race // addition later after verifying fit.
IDofspl=67.64;// to fit OD of 60 or 62 tooth spline
splsocht=6.00;// height of cup for spline
ODofCup=IDofspl+splsocht*2;// incorporate bearing in space
echo(11,ODofCup);
bb=4.36;// crosman bb dia plus clearance
//instclr=.4100;
// need some data for rotate_extrude
ctr_ht=splsocht/2;// center bb groove vertically
innr=ODofCup-splsocht/2;// get radius of bb groove
bbofs=splsocht/2;// might be useful
$fn=360;
translate([0,0,splsocht/2])
difference() {
// builds inner|outer walls of splined ring socket
cylinder(h=splsocht,d=ODofCup,center=true);// outer
cylinder(h=splsocht+1,d=IDofspl,center=true);//inner,1st
subtract bearing();
};// ends difference from line 20
// now cap it, this works! turn upside down to render
translate([0,0,splsocht+1.5]) // looks good
difference() {
cylinder(h=splsocht/2,d=ODofCup,center=true);// make hole in
center cylinder(h=splsocht,d=20,center=true);
};
// this code generates a [( )] shape for a ball bearing race pair in
// another file
module bearing() {
rotate_extrude()
translate([ODofCup,0,-10]) // below main gfx so can see
difference()
{
square(splsocht, center = true);
circle(d=bb);
square([.32splsocht, 1.1splsocht],center=true);
}
};
With that -10 in the translate I should see it below the main image
and could adjust it up into the difference, but no hits, no reported
errors, its just not there.
Once I can see it as a seperate item, the difference s/b become a
union, and the first square removed to get the shape for the 2nd
removal in the top difference chain.
I've been a day and a half now playing all those monkeys writing
shakespear, what am I doing wrong?
Thanks all.
Cheers, Gene Heskett

That worked fine, and I've made that difference into a union and added

With the #bearing(); I can see the break thru the top disk even at a .1mm
gap, too narrow to render but its not there in the render, so I'm
rendering to see if it is present with the # and a .5mm gap. And no,
that gap is not there in the render. The bearing race channal is there
but not the third argument. And it won't work without it.
So I'm bumfuzzled. This is the new version:

The preview looks great, but the render does not show the last square
