Removing pla from extruder

  • I read that the best way of removing ABS was to let the temperature at the hot end to drop to around 190deg c then a sharp pull. This worked really well. I am trying to print with PLA but no matter what temperature I drop the hot end to I get left with a length of PLA in the feeder tube. OK I can heat the hot end and poke the excess down with a wire but that is a pain. I think the technique is right but the temperature is wrong. Any help great fully appreciated.

    At what temp are you pulling? Btw this method is sometimes called the Atomic Pull.

    Looks like I had a gap between the hot end and the screwed rod. A gap filled with cool pla. A sort of washer for want of a better description. Will let you know if heating above temp is the answer

    Friendly reminder, I would edit you question when you a update, don't put it in the answer area. Personal experience :)

    Forgot to add that I am not sure for that, I don't have the experience... but maybe you can take it apar and clean it up real good, then a washer or something to close the gap. Heating it to 210*c will melt the pla, maybe you can brush it out with something?

    What is the `screwed rod`?
