Has anyone experienced this? I removed a piece of PLA about the size of a matchbox from the casing around the print head. The entire aluminium casing was full of material. I suspect it sprung a leak and continued to extrude. It has even bent the copper heating head so it no longer sits flush.

    This can happen on failed prints or it could have leaked if you didn't have enough pressure on the white PTFE coupler.

    Do you have any photos?

    This is common if your part doesn't stick to the glass and starts getting dragged around wtih the head part way through the print and then you walk away for 3 hours.

    You need to learn how to keep your parts sticking to the glass better but first - to fix this issue - realize that even hot tea is plenty hot enough to loosen the PLA. So get a hair dryer or a heat gun and start heating all that plastic up and then remove the fan shroud and then start removing it carefully. It's very easy to damage the 2 cables going into the back of the heater block so be careful and gentle back there!

    The newer printers come with a tiny white ring to block the path of PLA from your part up into the head. I guess you didn't get one of those :(
