From what it was in the beginning to now, its great. I finally passed the fight with extruding PLA at the correct diameter and my prints turn out much better than when using mgchemical filament! Good job Tim and Ian. The filawinder, hasn't let me down since I replaced the hall sensor. (had a broken leg and intermittent sensing) After that its been winding away!

*and frankly any other cheap filament producer's black filament.

Not far from the truth. Luckily there are shoulders of giants to stand on.

Now its your turn to have spoiled an otherwise perfect sarcastic post tongue lol smile

Industrial machines simply use a rusty basin plug, some stockings as a scrim, unicorn horn dust as lubricant and its all done at room temp. I fail to understand why you've made the filastruder so overtly complicated.

Even industrial machines use a melt filter, in fact that is where I got the idea. A guide at the end doesn't help, because often the pellets themselves have debris/contaminantion in them.

The correct solution is a melt filter. Look at an industrial machine for proof.

Grinding occurs somewhere creating metal flakes.
What this thing needs is some kind of a guide inside the tube.
If nozzle was metal instead of brass and drillbit had pointy tip at the end, it could be used as a guide. But for some reasons it was cut off. To get it shorter ?

Having such long drillbit pushing filament thru the tiny hole inside very little clearance tube is almost impossible without some kind of a guide at the front end.
Consequences are jammed 0.4mm printer nozzles and ruined prints and worse.

Turns out they weren't kidding - this had shreds of all kinds of stuff, like twigs and whatnot. It wasn't a lot by volume, but definitely visible. I decided to run it anyway, to give the ole melt filter nozzle a challenge. Here's the results, after running all 20 lbs:

https://dl.dropboxusercontent.com/u/1786359/Photo%20Feb%2017%2C%2012%2014%2045%20PM.jpg

The stuff on the towel is only what stuck to the melt filter - most of it ended up in that glob of ABS I peeled off. Then I dropped the melt filter in acetone for a day, and filtered the solution through that towel to show how much debris it blocked from getting in the filament.

I've printed all 20 lbs of it with no clogs. Filastruder output steadily decreased over time, towards the end of the 20lbs I saw about 70% of the normal extrusion speed I expect.

Layer heights as low as  .1 no problems. 3mm filament BTW, don't have any 1.75 filament nozzles or I'd test them too. today's task is rigging water cooling and air drying stations between my testing extruder and winder.

Filament printed with zero issues and no sign of contaminants. I'd say the filters are a success.

*there were a few small pieces of brass still of the inside from where they did the machining.  Probably best to clean this up before using.

Nice design and machining! And of course, mesh cannot be deformed this way.
It is remarquable how you lengthened the threading to have the mesh at right middle place (heating zone and nipple extremity. I guess you tried difference distances!

Sold.
