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.

Chamfers and fillets were the greatest improvements that I could have made to my designs and completely changed my style.

Not only did it improve my printed and designed parts visually, but also improved strength and printability.

By removing sharp corners from your designs, slower and older printers can more easily print your designs and the printing speed can easily be increased even with the lack of #LinearAdvanced and #InputShaping.

The strength is also improved by creating a small chamfer or fillet where a thin wall connects to a larger surface, by increasing the contact surface and sometimes enlarging the surface enough to allow for extra infill.

Finally, rounded corners also result in more consistent printed results, especially when you are printing many copies of the same part, due to the decrease in possible errors and shifts that could occur on sharp corners.
