About

A larger nozzle will result in much faster prints, right? Since it affects the printing volume it will affect it like this:

(new diameter / old diameter)^3
(0.8/0.4)^3 = 8

Hoorray! 8 times faster! At least I thought that…

The Problem

The prints were awful:

  • Outer Perimeters looked good, but walls were not completely filled
  • Infill looked uneven and hat "holes" in it
  • Looked like underextrusion, so I cranked up the extrusion multiplier (with no effect)
  • Triple-checked that extruder is working and the wires are not (again…) broken
  • After some googling I found Bob's Project Notebook (Mupped Labs) - which lead me into the right direction…

The Solution
