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
- …read on! The pictures will nicely illustrate what I've changed and what effect it had:
• \o/ this looked much better!]]
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.
