I have a clogged nozzle, but can’t seem to take it off the assembly. I’m heating it up to 235 degrees (for ABS) but as hard as I try, it just won’t come off. I tried printing some PLA awhile ago (and have since successfully printing in ABS) but I’m wondering if maybe some leftover PLA is gunking it up from the extra heat, or maybe this is a problem with a leaking nozzle. There’s a bit of plastic melted along the threads. Has anyone had similar problems?
You may want to try a lower temperature. We find that heating the hot end to 160C works well.
