When changing from a .4 to a .6 or even a .8 is there settings that need to be changed as well?
I installed a .8 and tried to print an object a few times trying different things. {changing plated and running leveling changing filaments}
I reinstalled the .4 and it is printing good.
What am I not doing right?
Please explain in old man speak..
Thank You
Pete
I’m not sure “upgrade” is the right way to think about it. Going from a 0.4 nozzle to a 0.8 nozzle is not automatically better, just like a 1/2" socket is not automatically better than a 1/4" socket. They are different tools for different jobs.
A larger nozzle mainly gives you more flow. Compared with a 0.4 nozzle, a 0.8 nozzle can lay down a much wider bead of plastic. That can help with speed and sometimes strength, especially for larger functional parts.
The tradeoff is detail and surface appearance. A 0.8 nozzle will not produce the same fine detail or smooth-looking walls as a 0.4 nozzle. The lines will usually be more visible, corners may look less sharp, and small details may not come out as cleanly.
A 0.2 nozzle goes the other direction: finer detail and nicer small features, but much slower printing and usually less useful for big functional parts.
Here is an example:
So the first question is what you mean by “not printing good.”
If you mean the part looks rougher than the 0.4 nozzle, that is expected and normal for a 0.8 nozzle.
If you mean poor layer adhesion, failed prints, under-extrusion, blobs, gaps, or the filament not sticking to the bed, then that is a different problem and likely needs slicer setting changes.
A photo of the same part printed with the 0.4 and 0.8 nozzle would help. Also include the slicer settings you changed, especially nozzle size, layer height, line width, speed, and temperature.
Plain English is fine. We all learn this stuff one setting at a time.
the .4 prints and the .8 doesn’t it just bunches and will not lay on the plate.
The piece I was printing is / was a bird bath and I believe they do not care how it looks.
