There are a lot of factors that come into play for dimensional accuracy. I have a system I developed for coming up with values for X&Y scale and horizonal offset that has worked well for me. Going real small on holes can still be a little tricky - like the tap drill for a 2mm thread is 1.6mm. I usua...

I could see this being useful - and should be pretty easy to implement.

Uncheck that box. Could create other issues due to overheating. Might need to leave it checked and adjust the settings. There's a similar setting under COOLING which you can also look at. I have had to add points under the temperature settings to reduce the temperature when features get smaller as w...

With so much disparity in the responses, looks like you might just have to start printing and figure out what works for you.

Sandpaper.

What kind of printer? Have you tried thinner layers? Not sure what you mean by "smoother". You will have steps - but you can control that somewhat with layer thickness. If it's the extra build up at the end of the solid infill runs, if your printer supports pressure advance or linear advances, that ...

#1 - you can scale models in X, Y, and Z. That combined with horizontal offset can yield excellent dimensional accuracy.

What leads you to believe they are not finishing? Looks like normal top layers stuff to me. The color difference is because you have it showing color vs print speed. Smaller surfaces will slow down to prevent overheating.

IMHO, a .32mm layer is too thick for a .4mm nozzle. I generally stay around or below 50% of the extrusion width. You might be getting some pulling of the extrusion on inside corners, although your .5mm width should mitigate most of that. The STL file is a mess and doesn't pass any of the S3D quality...

Thanks for the suggestions. I can try 2 perimeter shells, though not ideal for what I'm trying to do, still should work. Still seems that doing that outer perimeter as one continuous move and the vertical section as a new move would have been a more optimized path. I fiddle with a few things and se...
