Single Extrusion voids/bug

Fri Jun 14, 2019 2:29 pm

Been trying to work out why my machine was having some issues with extruding single lines - I thought it was the extruder so stripped the machined and cleaned everything, etc, still had the issue with single extrusions being underextruded and not meeting the perimeters - couldn't work it out out, but I just loaded a new model and when previewing, I can see clearly on this one the problem, the extrusions are doing some weird stuff, any idea what's causing this?

There's nothing "Causing" what you are describing......because there's absolutely NOTHING wrong! A 0.4mm wide extrusion will not mysteriously expand to fill a gap that is 0.6mm wide! There will be a gap.

Reduce your number of perimeters down to 2 and increase the (Infill) Outline Overlap to say 80%.....and the slicer will have a chance of filling the non-multiple of extrusion width gap!

Eh? It's a single extrusion that's causing the gap, you can see it's the correct width in half the points and not in others.

Works fine on other layers:

I'm not sure if it's just a rendering bug but it does seem to coincide with the models that have some issues with single extrusion fills.

Could you please post a Factory File where you see the gaps as represented in the first image?

I can send one in, but I can't post it here publically as the model is commerical.
