Thanks, I'll try slowing it down at the end and a little hotter.

Hi,
I'm trying the same thing!
What type of oil do you add? How do you add it ?
Thanks a lot!!!
Any mineral oil will work. Use a light oil.
So for example: baby oil, 3-in-1 oil, sewing machine oil, penetrating oil.
Food oils are not recommended but should work fine (they can go rancid). Oils with additives like detergents (WD40) not recommended either.
Drip the oil on the filament before it goes into the bowden. One drop is enough to coat the whole bowden. Maybe slide it in and out 3 times if you have the latest "plus" feeder or if you have iRoberti feeder.
Then add two drops of oil for every meter so that it is continuously coated. I uncoil the filament and it hangs down like a long string about a meter down and make sure it's coated every 20 minutes of printing.
I just used ninjaflex with UM2+ last week and it worked great.

Ok! Thanks a lot!
And how should i clean it after that?
Clean what? The filament? Just wipe the oil off. Or leave it on the filament. The print will not get significant amounts of oil on it - it's very subtle.

DEfinititely put oil on the filament - it won't hurt anything. I thought the oil might make holes or pockets in the print but it doesn't.
I would try using the feature in cura "cut off bottom" or whatever it's called and practice/experiment with printing those last few layers only. I had to go down to even 10mm/sec I think and a little hotter - 240C to get zero underexturions. And one drop of oil every meter or so and let the filament hang loose to the floor.
