I've seen a lot of threads with PLA jamming the hot end, but I somehow managed to do it with abs (black if it matters). The jam starts a little under an inch from the tip of the hot end. I've tried heating it up to 250C and pushing it out from the top (worked for a PLA jam a few weeks ago), but it didn't seem to help. I also tried an acetone bath for about 15 min, but that didn't help either. Any ideas?
