No, I have nothing against traditional Dutch footwear, its the clogs which jam up my printer when I do something dum that I dun' like. In this case I know what happened, I had been messing with retraction, and ramped it up to a higher than normal value when I was testing the Hatchbox wood PLA using my BMG direct drive. I think I must have left the retraction high when I went to print something else using regular PLA, and that must have sucked some plastic into the colder part of the heatbreak.
I was getting prints that looked like sponges so I pulled the nozzle off and removed the heatbreak. The clog can be seen in the pic above, it almost looks like the end of a PTFE tube in a non-all metal hot end, but don't be fooled, its a nasty clog, and has to be removed to get the printer working again. To dislodge the clog, I used the blunt end of a 1/16" drill bit bit to push it out with the block removed (with the heatbreak installed but the nozzle removed), and heated to 180°C. Once at temp, with the plastic softened, I pushed the drill bit through a couple times to evict the clog. After that I took the opportunity to swap in a plated MK8 (brass) 0.6mm nozzle which looks like it will work nicely.
