it took me 7 years to figure out that the most reliable cold-pull on my 3d-printer should be done at two different temperatures and speeds. At 110 degrees, I quickly pull it out 4cm to narrow down the part that could get stuck on the bowden tube. Then at 100 degrees I slowly pull it all the way out to extract all the filament out of the nozzle (for filament change and/or for unclogging)
