J1 Clogged hotend repair

I had an unusual problem yesterday. I had started a print of a nut that I got off Thangs and when it started to print it dragged the nozzle across the bed and made a nasty scratch in the surface. I can deal with that, but it also left the nozzle severely clogged, is there any other kind? I’m not entirely comfortable with dissecting a new machine that I had hoped would be pretty trouble free but I was forced to remove and replace the hotend, the very easy part. I completely disassembled the hot end and was able to remove the clog, pretty easy as well but considerably more anxious about that… I have cleared the clog and replaced the hotend, calibrated and just started to offending print again and it started as it should. Pretty happy about that and I’m slowly becoming a bit more confident in my abilities.
