So the 0.4mm vs 0.6mm nozzle debate is nothing new in #3dprinting, but it is something I've lived in denial about.

I have used different nozzle sizes before, especially when printing larger enclosures for some of my projects. I can easily use anything from a 0.6mm all the way to a 1.2mm nozzle. It can easily reduce a print by 4 to 6 hours.

But I always find myself switching back to my "default" 0.4mm nozzle as soon as I am done with such a project.

This debate is nothing new and with #Aracne in #prusaslicer you might not even notice the difference switching 0.6mm.

But I have found myself at an impasse.

My 0.4mm profiles are just so well tuned after years of printing. Perfect first and top layers. Excellent strength, long bridges and no stringing. I couldn't ask for better!

But now switching to my 0.6mm nozzle, I can see I have a lot of work cut out before I'll be cutting any printing time.

My first steps will need to be #LinearAdvanced tuning with the K-test.

Linear Advance is a technique for controlling the pressure in the nozzle, especially around corners and tight spots. It simulates the filament like a spring, using a K factor.

Something many don't realise, is that this not only helps with corners, curves and turns, but also layers.

You might have noticed that your first layers and infill is good, until the printed reaches the edge perimeters. You then find these blobs and almost over extrusion as the printer slows down, but keeps on extruding the same amount of plastic.

I am clearly seeing this in my first layers and top layer now.

Damn I love this place.This post is sandwiched between the Dominion judgment and Rupert Murdoch.
Kind of where I wanna be.
