Weak prints
OK, I totally messed up some parameter, somewhere in the application. everything I print is very weak, transparent (at 3 outside perimeter thickness), spongy looking, (you can see and feel it looks very "spongy"), falls apart when twisting the print. I don't know how to recover. would my best bet be to uninstall the application and then reinstall (to get back to the default settings)? I only use slic3r, not cura ( using this slicer will not give me a top layer on the prints). I've never even tried the third slicer, it seemed awkward. Any ideas?

Have you seen the problem I described before? It was driving me crazy. My prints would sometimes come out very
loosely formed, with lots of very rough surfaces.
I did everything to figure it out.
I checked the PID, extrusion speed rate, printer and slice extrusion
settings, you name it, I checked it.
It wasn’t until I printed my white ABS that I noticed that when the
object printing started looking good that I noticed the black specks.
I took apart the extruder and noticed that there was a crusty black junk
in the stem that connects to the aluminum block.
Turns out that the Teflon tube
is only rated for about 265c before it breaks down and my printer had a temp runaway printing nylon and shut down at
275.
I do have a question. Is this Teflon tubing used to determine what size
filament the printer can use. It has an inside diameter of 2mm, and the whole
it fits into is 4mm.
If I were to replace it with an inside diameter of >3mm
(or not use any Teflon at all, could I push 3.0 filament thru the printer?
What is the purpose of the Teflon? Does it
act like a washer to prevent the filament from leaking upwards into the
extruder motor?
Is 0.25mm (filament is 1.75mm) difference enough to prevent the
melted filament from leaking upwards?
Just
asking, trying to learn more about this printer.
Sincerely,
Israel
