Hi all,
I've recently been seeing very thin strands of filament (~0.1-0.2 mm) hanging off in some of the parts (might be difficult to see in my attached image). These seem very different and much thinner than the loose filament strands you would see with over-extrusion. They're almost like the thin strands left over from using a hot glue gun, if that makes it clearer. I had only encountered this once before when I was first testing the Taulman Bridge nylon filament but am now seeing in with ABS.
I'm using 1.75mm Sainsmart black filament with a Jhead hotend, nozzle diameter 0.4mm. For whatever reason, I've also had to run my hotend at a much lower temperature (~218C) to keep it printing smoothly. I've also recently cleaned out my nozzle, so I don't think it's residue from a previous clog.
Has anyone else experienced anything similar?
Thanks!

Re: Thin, fuzzy stringing in prints
I don't think I can see the strands you're talking about, but It sounds pretty similar to what I'm getting. Printing the same parts with the same settings, I gradually began to see more and more very fine fuzz. I asked support about it, and was advised to try changing the hot end liner. I've done that, but the fuzz hasn't cleared up.
In my models, it consists of very fine, hairlike strands that only appear *inside* the tubes I'm printing. Most strands seem to cross the piece from one side to the other, following the movement of the printer head. I'm printing wind instruments (#Qwistle on Twitter for more about that) - it'd be great if I could persuade my printer to go back to printing the pieces clean on the inside. Here's a photo - here also, the 'hairs' are hard to see as they're so fine, but the internal bore of the tube is literally full of them, criss-crossing, so fine that they disappear in the light.
Sorry I can't help you with the reasons for this, but I'm hoping with two examples to look at, someone might be able to provide a tip as to how to stop this happening.

Re: Thin, fuzzy stringing in prints
I just followed up on some old advice, and went over to Cura.
The 'candy floss' has disappeared completely which is brilliant. The catch is, the piece has some wafer-thin support structures that are now disappearing during slicing. The piece itself is ok quality, much better than before, but without the supports it just falls over. Does anyone know how to get Cura to recognise these wafer-thin (0.5mm) structures, and include them in the geode?
