So the quality of my prints started to drop a few weeks ago, after having not used my bukobot for a while.
I think I've tracked the problem down to something to do with the extruder?
After printing the first few layers successfully, the prints become a weird, spongy spider web of plastic instead of the solid shapes they should be.
Some prints will get quite a way in before the issue creeps in but with others its apparent sooner, although it seems like its getting worse.
For some reason solid, simple shapes haven't been exhibiting this problem to the same degree as more complex organic shapes.
The issue seemed more apparent on support material as opposed to the main body of the print when i first started to notice it.
I used to do a manual extrude and get fast thick streams of plastic that zipped out, often forming a plastic cylinder.
Now when I do a manual extrude from repetier host it is an incredibly slow, thin stream of plastic that takes a long time to finish extruding, even for a small amount. The stream of plastic hardens in a straight line from the tip of the nozzle it moves so slow. I can imagine if it was extruding like this when it should be extruding like it used to, that would explain my current prints.
This originally lead me to believe that it was a clogged nozzle, a problem with the stepper motor on the extruder or something in that vein, something physically wrong with the hardware of the printer.
My machine has always done intermittent extrusions once the extruder is heated past a certain point. It still does these random extrusions and they are fast streams of plastic, just like they should be!
At first I thought it was slic3r giving me issues but I've run gcode from Kisslicer and had the same problem.
I've had the problem with repetier host 0.95f and also 0.85b.
I've tried re-uploading the marlin firmware, as well as a few other things but the issue persists.
I'm pretty stumped, any ideas would be much appreciated!
