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
#1: • gaps in walls
• infill…barely "infill"…
(• first layer height too low)

The Solution

Lessons Learned

As the author should already have known from RFC1925(8,9) is:

(8) It is more complicated than you think.
(9) For all resources, whatever it is, you need more.
