Whoops, my fan had come unplugged and didn’t notice, first few layers were fine so headed off the the shower.
On return it’s not extruding, so let temp drop to 70 do do a cold pull to notice that it’s cooling down really slow, then I notice I can’t hear the fans and see they’re off.
Well this will be fun to remove :-\
If you have a heat gun, slowly bring it up to cold pull temp and cold pull all the way down. Shouldn’t be terribly difficult to remove.
@ThantiK not a bad way to do it,
As it is I just removed the fan mount and let the whole thing heat to 180, was able to pull it out from the top.
Now reassembled, just nee to print a new lower guide as I had to snap the old one to get it off
