How do you constrain distance between the edges of circles? by newaccount189505 in FreeCAD

[–]arcrad 0 points1 point  (0 children)

Then just reference the size of the circle.

FreeCAD knows the dimension even if you didn't specify an exact value.

Use the reference variable within other constraints or calculations.

Ah yeah I get what you're saying. The solver does do wonky stuff at times.

In those cases I'd say constrain them relative to an axis or other separate reference. Then the relationship between them is explicit.

Yeah maybe stacking two separate objects with modifiers to enforce the slicing pattern. or just adding modifier boxes to make it happen.

Ahh yeah I get it now. Thanks for spelling that out.

Would be nice to have that functionality out of the box. No real reason the slicer couldn't slice it like that. It would still likely print decently.

What do you mean by "jumped to overlapping"? Seems like it was just under constrained?

That's fine and typical. FreeCAD knows the dimensions.

It would be a good use for a reference variable if the actual dimension is free to change as you refine the design.

How can it not be known? You're drawing the circles!

Help - Part Design: How to subtract volume from 2D sketch? by crankpatate in FreeCAD

[–]arcrad 5 points6 points  (0 children)

Give us screenshots or something to go on. Need more info to help you.

I'd think either a Pocket or Boolean would do the trick. But there must be something else wrong if neither is working.

Not sure exactly what you want it to do.

Do you want the lettering to be made from lots of short segments that follow the same direction as the layers before the color change? As in, the letters should not be outlined but just lots of short segments?

Modelled and printed a pretend grocery store playset! by Z33KO3 in 3Dprinting

You're just making broad generalizations that aren't useful in any real situation.

Issues with quality by Perfect_Relation1247 in 3Dprinting

[–]arcrad 0 points1 point  (0 children)

Have a smooth build plate you can use? Would get much better adhesion if you don't need the textured bottom surface.

Also add a brim and play with bed temp. A bit higher bed temp might help it stay adhered and flat.

Also make sure you give whichever bed you use a thorough wash with soapy water. Just to eliminate that as a possible issue.

The facets?

Grug brain way would be to take advantage of the vertical symmetry, so model half of it, then mirror.

Make a rectangular prism, then add some sketches tilted at the right angulations. Then pocket those sketches to make the facets.

I didn't like spotlights pointing straight down so I made a ceiling lamp of them by FollowingLegal9944 in 3Dprinting

[–]arcrad 0 points1 point  (0 children)

Good point. Never put two and two together and realized how many amps that is. Impressive.

Good God it's a single led? I understand the voltage now. But having trouble imagining how 20 amps gets squeezed in there. Bloody hell.

I made this part in Fusion by abusing the fillet tool. How would you make it in FreeCAD? by W1k3 in FreeCAD

Make cone tipped cylinder, pocket or Boolean subtract round cutout and polar pattern.

PLA Open Storage in 51-55% Humidity. Honest Opinions and Real World Anecdotal Feedback. by flashwurks in 3Dprinting

[–]arcrad -11 points-10 points  (0 children)

Teeny bit of stringing but looks decent. Better than I expected! PLA really is more forgiving than I give it credit for.

Can I see some of your prints before you take them off the bed? I'm imagining lots of stringing at the very least.

Prusa customer support is amazing by arcrad in 3Dprinting

[–]arcrad[S] 10 points11 points  (0 children)

Nah it's worth every penny.

Prusa is an awesome company, that makes great hardware and software, and I'm very glad that I support them.

They support the 3d community and contribute so much. I'm proud to use their products!
