Re: Gaps in top and bottom layers

But the new 0.35 nozzles are steel and the old one was brass. Can make the difference because they have different coefficient of thermal conduction. 303 Stainless Steel has 14% the thermal conductivity of 360 brass - so if enough plastic is being pushed through the nozzle a stainless nozzle might n...

Re: Gaps in top and bottom layers

Partially clogged nozzle.
inadequate drive pressure in the extruder.
Print speed too high.

Re: Where's the Small Perimeter Settings?

Have you looked at the Extra Restart under the retraction settings?

Re: relation between warping and infill patterns

I'd run a 4"x4X"x1" square with sharp corners - and I agree with extremeshok - ABS would be a good test material. I hope you'll share your findings with us.

Re: Thin Walled Wing Printing

I wouldn't expect those settings to do anything if you are printing the overlapping pieces with different processes. You will have to tweak your overlap settings by tweaking your geometry, or perhaps scaling of the ribs to adjust overlap.

Re: Thin Walled Wing Printing

Thanks for replying zemlin. I am new to S3D, how do I apply different process to the skin and the ribs? Would I have to import them as separate models or can I select different regions of a model? You need to load the skin and ribs as separate models. I don't know of any tricks for aligning models ...

Re: Thin Walled Wing Printing

Use different processes for the outer surface and the ribs. That way the outer surface will always print continuous and you can set the overlap for the ribs to get the bond strength you need. There may be small artifacts of the ribs on the wing surface, but it should not interrupt the surface printi...

Re: Single layer font

I like that idea, but it borders adding modeling features to a slicing program - and geometry creation is a whole different animal from slicing. From a feature standpoint, perhaps it could be handled as a way to handle single-layer geometry so it does not impact the underlying infill pattern. It's p...

Re: Perimeter Grid?

I think what you'd need to do is create two models. One with the x-axis walls and one with the y-axis walls. Overlay them in S3D and assign a different process to each one. When you slice you'll get a warning about overlapping geometry - ignore that. Then (I think) it will print the walls the way yo...
