How close should my nozzle be to the bed?
Your 3D printer nozzle should be from 0.06 – 0.2mm from your printer bed to give it enough space to comfortably extrude material, which is about the width of a piece of paper. This distance also does depend on your nozzle diameter and layer height.
What is nozzle height?
Introduction. Nozzle height value (Z value) determine the height where the extruder start to print. If the nozzle height value is too large, in other word nozzle too close to platform, then it will start to scratch the build surface and prevent material being extruded, eventually cause the nozzle to be clogged.
How do you know when to change the nozzle?
There isn’t a specific time frame in which you should change or replace your nozzle, but generally you should change your nozzle every 3-6 months. This really depends on how often you are using your 3D printer, what kind of filaments you are using, and how high or low the quality of your nozzle is.
How often should you clean your 3D printer nozzle?
Poor quality or cooked/burned filament can leave residue in your nozzle. Even PLA can solidify in the nozzle over time, so we advise flushing it through at least every 200 – 400 printing hours.
Do you need to readjust 3D printing nozzles?
It is expected that long before the nozzle reaches this state, you need to readjust the bed to nozzle distance and the flow modifier, you will see this in the quality of your prints and the first layer sticking to the bed.
How can I tell if my nozzles are wearing out?
Check the length and you are done. TL;DR You could compare the nozzle to a similar new nozzle to look for wear. The creators of the Olsson Ruby Nozzle have published some pictures of wear on brass, steel and hardened steel nozzles.
Can a carbon fiber printer nozzle be damaged?
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 nozzle has taken a significant amount of wear.
What kind of steel is Olsson Ruby nozzle made of?
The creators of the Olsson Ruby Nozzle have published some pictures of wear on brass, steel and hardened steel nozzles. From their website the following image is taken: Depending on the amount of filament that is being printed, not only the internal dimensions, but also the outer dimension change considerably.
