How to identify nozzle wear

E3D-Online and Make Magazine have written about the potential damage printing carbon fiber and glow in the dark filaments can do to your printer's nozzle. What I can't seem to find is what clues or warning signs to be on the look out for if your…

Why is it conventional to set line width > nozzle diameter?

I recently became curious about the Line Width setting in Cura and why one might change it if they aren't using different size nozzle. Since I've gotten my Ender 3, I've always kept the line width equal to my nozzle size (0.4 mm). I've looked around…

Which is the difference between MK6 and MK8 and even MK10?

I made and assembled my own 3D printer two years ago and I notice that some extruders are MK6 and MK(*whatever). Some of them has the block fuser horizontal and others vertical, then uses a nozzle longer. The block heater that I made was an aluminum…

Ender 3 nozzle homes off the bed in the Y axis

I just received my new Creality Ender 3. I was going through and checking/adjusting everything for alignment, and I noticed that when you "auto home" the print head, the nozzle stops off the front of the print bed by 5-10 mm. Is that normal? Is it…

Will I see a noticeable difference switching from a .4mm to a .3mm nozzle?

I currently print with a .4mm nozzle on my extruder, and my prints seem to come out fairly accurate; would I see much of a difference if I went to a .3mm? What are the pros and cons of larger and smaller nozzle sizes?

How close should the nozzle be to the substrate?

I have my nozzle close to the substrate that I am printing on, so that a piece of paper can just about slide underneath it freely, without catching. Is this the right way to do it?

Slicer line width vs. extrusion multiplier for layer adhesion?

My question would like to address what would be better for adhesion and general quality and possibly strength: either increase the slicer line width option or increase the slicer extrusion multiplier for layer to layer adhesion? This question has a…

Ultimaker Layer Resolution vs Nozzle Size

On their website they say the following 0.25 mm nozzle: 150 to 60 micron 0.40 mm nozzle: 200 to 20 micron 0.60 mm nozzle: 400 to 20 micron 0.80 mm nozzle: 600 to 20 micron That confuses me. Why can I go down to 20 micron with the 0.40, 0.60 and…

Wear resistant nozzles

I recently purchased some glow-in-the-dark PLA filament (just "because"). Being new to 3D printing, I didn't realize you shouldn't run this type of filament through a standard brass nozzle and should replace it using a "wear resistant" type nozzle.…

How thin can my extrusion be from a 1.2mm extruder?

I always assumed that the smallest diameter that you could extrude was equal to the diameter of the extruder tip itself. Recently I heard that you can actually extrude a line that's as little as half the width of the nozzle opening. Is that true in…

What is the purpose behind a glass nozzle?

So while doing some research I stumbled upon a wiki page on reprap from a few years back where the user was creating a glass nozzle to replace the brass and PTFE assembly.1 Does anyone know the theory behind this? Glass is a great insulator so I…

Are Makerbot Smart Extruder nozzles swappable?

I'm wondering if anyone has any experience with Makerbot smart extruders and knows whether or not the nozzle size can be changed. I'm trying to figure out if I can use different nozzle diameters (0.25mm, 0.5mm, 0.8mm, etc.). Makerbot doesn't sell…

Teflon tubing in nozzle throat coming out?

I have a HE3D prusa XI3 printer with an MK8 extruder. While printing or testing, the extruder makes a clicking noise as if the filament isnt getting hot enough to extrude. I began my investigation and read about many reasons why this could be…

Tevo Michelangelo nozzle below build plate?

I got a Tevo Michelangelo as first 3D printer today and already got a problem with the bed leveling: The extruder nozzle is way below the build plate. (When I auto-home the axes, which I've done several times). I thought to just adjust the plate…

Geeetech Prusa i3 Extruder seems to push more filament, gear slips/skips?

I got my first printer, a Geeetech Prusa i3, and for the price I paid (160$) I am so blown away. As I saved so much money, I treated myself to a legit copy of Simplify3D, which I am happy with. I'm using white PLA filament (supposedly 1.75 mm) with…
