You don't use lubricants for your bearings or threaded rods?Quote

I have printed for thousands of hours with PLA, without ever adding a drop of oil or other lubricant to my system. It doesn't seem like something a well-made system would need.
Nope,Quote
In fact, it seems like it could cause problems with bed/layer adhesion, more than anything.

Are you interested in solving the problem, or are you happy just applying oil to your system?

I've now printed this whistle:
It was not possible to print it before. My extruder would jam and grind the filament. Only thing changed is the added oil.

10mm retraction?
I use only 0.5mm and advance 0.1 when print starts after retract.
There are some hairs in the print, but a quick burn from cigarette lighter will remove it without damaging the part itself.
Use piezo lighter, NOT torch. The "click" will give you fast flame ON - OFF

10mm retraction is a problem, too. You're pulling softened/liquid filament up into the cold end of the hot-end which causes it to solidify and then it "jams" and your extruder chews a divot into the filament because it isn't biting into the filament deeply enough. Reducing retraction to a more reasonable value like 1 mm or so and increasing pinch roller pressure, so that when things get a little tight the motor has half a chance of pushing on through, should fix the problem. Stringiness is more a function of temperature than retraction. Retraction fixes blobs.
When you're ready to actually fix all the problems and print reliably, get an extruder with a geared drive (try an E3D titan- you can use the motor from your old extruder), a decent hot-end, and a bed heater that will get you up to print temperature. 0.4-0.5 W/cm^2 does the job unless you have a super massive bed. Use 3 point leveling instead of 4. While you might get 4 to work, 3 is much easier, faster, and usually more stable. With 3 point leveling and a proper heater/bed plate you'll be able to print edge to edge on the bed instead of just at the center.
